• Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep cord away from heat, oil, sharp edges or

moving parts. Damaged or entangled cords increase the risk of electric shock.

• When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of

electric shock.

• If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces

the risk of electric shock.

Personal Safety

•

Stay alert, watch what you are doing and use common sense when operating a power tool.

Do not use a power tool while you are tired or under the influence of drugs, alcohol or

medication. A moment of inattention while operating power tools may result in serious

personal injury.

• Use personal protective equipment. Always wear eye protection. Protective equipment such

as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate

conditions will reduce personal injuries.

• Prevent unintentional starting. Ensure the switch is in the off position before connecting to

power source and/or battery pack, picking up or carrying the tool. Carrying power tools with

your finger on the switch or energising power tools that have the switch on invites accidents.

• Remove any adjusting key or wrench before turning the power tool on. A wrench or a key

left attached to a rotating part of the power tool may result in personal injury.

• Do not overreach. Keep proper footing and balance at all times (Fig. 1). This enables better

control of the power tool in unexpected situations.

• Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing, and gloves

away from moving parts. Loose clothes, jewellery, or long hair can be caught in moving

parts.

• If devices are provided for the connection of dust extraction and collection facilities, ensure

these are connected and properly used. Use of dust collection can reduce dust related

hazards.

• Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can

cause severe injury within a fraction of a second.

Power Tool Use and Care

•

Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for

which it was designed.

• Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must

be repaired.

• Disconnect the plug from the power source and/or the battery pack, if detachable, from the power tool before making any adjustments, changing

accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

• Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the

power tool. Power tools are dangerous in the hands of untrained users.

• Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power

tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

• Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

• Use the power tool, accessories, and tool bits, etc. in accordance with these instructions taking into account the working conditions and the work

to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

• Keep handles and grasping surfaces dry, clean, and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe

handling and control of the tool in unexpected situations.

Service

•

Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power

tool is maintained.

Chainsaw Safety Warnings

•

Keep all parts of the body away from the saw chain when the chainsaw is operating. Before

you start the chainsaw, make sure the saw chain is not contacting anything. A moment of

inattention while operating chainsaws may cause entanglement of your clothing or body

with the saw chain.

• Always hold the chainsaw with your right hand on the rear handle and your left hand on the

front handle (Fig. 2). Holding the chainsaw with a reversed hand configuration increases the

risk of personal injury and should never be done.

• Hold the power tool by insulated gripping surfaces only, because saw chain may contact

hidden wiring or its own cord. Saw chains contacting a “live” wire may make exposed metal

parts of the power tool “live” and could give the operator an electric shock.

• Wear safety glasses and hearing protection. Further protective equipment for head, hands,

legs, and feet is recommended. Adequate protective clothing will reduce personal injury by

flying debris or accidental contact with the saw chain.

• Do not operate a chainsaw in a tree. Operation of a chainsaw while up in a tree may result

in personal injury.

• Always keep proper footing and operate the chainsaw only when standing on a fixed,

secure and level surface. Slippery or unstable surfaces may cause a loss of balance or

control of the chainsaw.

• When cutting a limb that is under tension, be alert for spring back. When the tension in the

wood fibres is released, the spring-loaded limb may strike the operator and/or throw the

chainsaw out of control.

• Use extreme caution when cutting brush and saplings. The slender material may catch the

saw chain and be whipped toward you or pull you off balance.

• Carry the chainsaw by the front handle with the chainsaw switched off and away from your

body. When transporting or storing the chainsaw, always fit the guide bar cover (Fig. 3).

Proper handling of the chainsaw will reduce the likelihood of accidental contact with the

moving saw chain.

• Follow instructions for lubricating, chain tensioning, and changing accessories. Improperly

tensioned or lubricated chain may either break or increase the chance of kickback.

• Keep handles dry, clean, and free of oil and grease. Greasy, oily handles are slippery

causing loss of control.

• Cut wood only. Do not use the chainsaw for purposes not intended. For example: do not

use chainsaw for cutting plastic, masonry, or non-wood building materials. Use of the

chainsaw for operations different than intended could result in a hazardous situation.

• It is recommended that the first-time user should have practical instruction in the use of the chainsaw and the recommended protective

equipment from an experienced operator. The initial practice should be cutting logs on a sawhorse or cradle.

• Other than the wear parts identified in this manual, the chainsaw has no user serviceable parts.

• The work piece, bar, and chain can be hot after cutting. Wear gloves to avoid burns.

• Prolonged use of power tools has been reported to cause vascular, muscular, and/or neurological disorders (such as vibration white finger or

Raynaud’s syndrome), particularly when operating the tool in cold weather. If you experience numbness or loss of feeling in your extremities, stop

using the tool until symptoms fade. To reduce the incidence of vibration induced trauma, follow these instructions:

• Wear gloves and keep hands and body warm.

• Maintain a firm grip on the chainsaw, but do not use prolonged, excessive pressure. Let the chainsaw do the work.

• Assure that the cutting system is maintained properly.

• Take frequent breaks.

• The vibration in normal use can differ from the stated values in this manual, depending on the material being cut, maintenance of the cutting

system and other factors.

• Keep the cord behind you and know the position of the cord at all times. Keeping the cord behind you and knowing the position of the cord will

help minimize tripping hazards and prevent severing of the cord with the chainsaw.

• If the cord is cut or damaged, immediately stop using the chainsaw and disconnect the cord from the mains. A damaged or cut cord increases the

risk of electrical shock.

• When used in a wet environment use a GFCI with a tripping current of less than 30mA. Use of a GFCI reduces the risk of electric shock.

Causes and Operator Prevention of Kickback

•

Kickback may occur when the nose or tip of the guide bar

touches an object, or when the wood closes in and pinches the

saw chain in the cut.

• Tip contact, in some cases, may cause a sudden reverse

reaction, kicking the guide bar up and back towards the operator.

• Pinching the saw chain along the top of the guide bar may push

the guide bar rapidly back towards the operator.

• Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. Do not rely exclusively on the

safety devices built into your saw. As a chainsaw user, you should take several steps to keep your cutting jobs free from accident and injury.

• Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as

given below:

• Maintain a firm grip with thumbs and fingers encircling the chainsaw handles, with both hands on the saw and position your body and arm to

allow you to resist kickback forces. Kickback forces can be controlled by the operator if proper precautions are taken. Do not let go of the

chainsaw.

• Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chainsaw

in unexpected situations.

• Follow the sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback.

Kickback Safety Devices on this Saw

• DAN

GER: NEVER MODIFY OR ATTEMPT TO DISABLE THE CHAIN BRAKE.

• DANGER: ONLY USE REPLACEMENT BARS AND CHAINS SPECIFIED BY THE MANUFACTURER. INCORRECT REPLACEMENT BARS

AND CHAINS MAY CAUSE CHAIN BREAKAGE AND INCREASED RISK OF KICKBACK INJURY.

• CHAIN BRAKE

• This chainsaw comes equipped with a chain brake, which stops both the motor and the

motion of the chain when kickback occurs (Fig. 4). The chain brake can be activated by

the forward motion of the front handguard as the saw rotates backward during kickback; it

can also be activated by the inertial forces generated from a kickback event.

• CHAIN

• This chainsaw comes equipped with a saw chain that met the reduced kickback

performance requirements of the American National Standards Institute (ANSI) and

Canadian Standards Association (CSA), ANSI B175.1, ISO 9518, and CSA Z62.3

respectively, when tested according to the provisions of the standards. For replacement

chain, contact the manufacturer.

• BAR

• This saw comes equipped with a reduced kickback guide bar that has a small radius nose. Smaller radius noses have less potential for

kickback than a bar of the same size with a larger nose radius. When replacing the bar, only order the bar listed in this manual to maintain low

kickback performance.

Storage, Transporting, and Disposal

• S

TORING THE CHAINSAW

• Unplug the chainsaw.

• Inspect the cord for cuts or damage.

• Clean chainsaw thoroughly.

• Install the guide bar cover.

• Store in a dry place.

• Keep out of reach of children or pets.

• It is normal for a small amount of oil to seep from the guide bar when the chainsaw is not in use. To protect against seepage, install the guide

bar cover and place an absorbent pad under the bar.

• TRANSPORTING THE CHAINSAW

• Tools can shift during transport. Ensure the tool is secure and cannot fall or move into contact with people or property.

• Unplug the chainsaw.

• Install the guide bar.

• If desired, drain the bar and chain oil to reduce seepage.

• CHAINSAW DISPOSAL

• This product is designed and manufactured with high quality materials and components which can be recycled and reused. Upon product end-

of-life, the electrical appliance should be disposed of separately from household waste. Please dispose of this equipment in an environmentally

correct manner at a local community waste collection/recycling centre.

Preparing for Use

DANGER: To avoid serious personal injury, do not operate the chainsaw without the guide bar, saw

chain, and side cover properly assembled.

WARNING: Do not attempt to operate the chainsaw if any part is damaged or missing.

WARNING: An electric power tool that is plugged in can start accidentally. Unplug the chainsaw before

preparing for use or performing maintenance.

Checking the Front Handguard Position

After unpacking the chainsaw, check the position of the front handguard. The chainsaw will not run with the

chain brake engaged. Pull the front handguard back towards the front handle before operation (Fig. 5).

Filling the Bar and Chain Oil Reservoir

IMPORTANT: Bar and chain oil prevents premature wear. Never operate the chainsaw if oil is not visible

in the inspection window. Check oil level frequently and fill as needed.

Bar and chain oil is required to properly lubricate the guide bar and saw chain. The chainsaw is equipped with an

automatic oiler that deposits oil on the bar and chain when running, keeping them properly lubricated. Use

manufacturer-supplier bar and chain oil for best results. It is specially designed to provide low friction and faster

cuts. NEVER use oil or other lubricants that have not been specifically designed for use on the bar and chain.

This can lead to a clogged oil system which may cause premature wear of the bar and chain.

Operation

Introduction

This chainsaw is designed for occasional light-duty use. It is not designed to fell large trees or cut large diameter

logs. This chainsaw is not designed for tree service. Do not cut trees or wooden timbers that have a diameter

greater than the effective cutting length of the chainsaw, 40 cm (16 inches).

General Operation

DANGER: To avoid serious personal injury, do not

overreach and do not stand on a ladder, step stool, or any

raised position that is not fully secured. Never cut above

shoulder height.

WARNING: To reduce the risk of injury, always wear

proper boots, gloves, head, ear, and eye protection.

Grip

Always grip the tool with both hands. Grasp the front handle

with the left hand and the rear handle with the right (Fig. 17).

Wrap the fingers over the top of the handle with the thumb

below the handle.

Testing The Chain Brake

Make sure the chain brake is working before using the chainsaw. To check brake operation:

1. Place the saw on a firm, flat surface.

2. Start the saw briefly.

3. Keep the left hand on the front handle and roll the left wrist to move the front handguard forward to manually

activate the chain brake (Fig. 20).

4. Release the trigger switch.

A properly functioning chain brake stops the motor and saw chain immediately. If the motor and saw chain

do not stop immediately, have the chain brake checked at an approved service location.

5. Return the front handguard to operating position.

Power Cord Use and Care

Selecting An Extension Cord

Select an extension cord that is:

•

Specifically labelled for outdoor use

•

Of a wire size (AWG) heavy enough to carry the current the full length of the cable according to the table

below

Select the gauge of extension cord based on the desired length and the electrical specifications found on the

product label. These are the recommended gauges based on the length of cord.

Make sure the insulation is free of cracks and that the plugs on both ends are undamaged.

Using The Strain Relief Bracket

It is important to use the strain relief bracket for two reasons:

•

It saves wear on both the power cord and the extension cord and their plugs.

•

It prevents the chainsaw from becoming unplugged from the extension cord accidentally.

To use the strain relief bracket, bend the extension cord into a U-shape and put it through the hole in the rear

handle. Slide the loop of cord over the hook and tug lightly until snug (Fig. 21).

Cutting

WARNING: To reduce the risk of injury, wear

proper boots, gloves, head, ear, and eye

protection.

WARNING: To reduce the risk of electric shock,

make sure the cord insulation is intact and that

the cord is in a dry location where there is no

danger of it being cut or tripped over.

WARNING: To reduce the risk of injury, always

be sure of footing and hold the chainsaw firmly

with both hands while the motor is running.

WARNING: To reduce the risk of injury, plan

ahead and plan multiple escape paths before

beginning work.

CAUTION: Establish a bystander safety zone of 6 m (20 ft) prior to operation of this equipment.

Bystander safety zone is a minimum 6 m (20 ft) circle around the operator that must remain free from

bystanders, children, and pets (Fig. 22). Felling operations require a larger safety zone according to the

size of the tree, see “Felling a Tree” section.

IMPORTANT: Practice cutting logs on a sawhorse or cradle until you become comfortable operating the

saw.

To get the best performance and to operate the saw safely, follow these instructions:

•

Observe all applicable national and municipal rules and regulations for cutting.

•

Take frequent breaks to reduce the risk of injury.

•

Before beginning to cut, make sure the saw chain is properly tensioned and the chain is sharp.

Saw chains are made to cut wood only. Do not use the chainsaw to cut any other materials, and do not allow the

chain to come into contact with dirt, stones, nails, staples, or wire. These materials are extremely abrasive and

will wear away protective plating from the chain in a very short time.

Sharpen or replace the saw chain if any of these conditions occur:

•

The pressure required to make cuts increases noticeably.

•

Wood chips coming off of the chain are very fine or dust-like.

Do not work with a dull chain as it will increase the effort required to cut, cause jagged

cuts, increase wear on the chainsaw and increase the risk of kickback. Never force a dull

chain to cut.

•

Assume the proper cutting grip and stance in front of the wood with the saw turned off. Press the trigger

lock-out and squeeze the trigger switch. Let the chain reach full speed before beginning the cut.

•

Begin cutting by lightly pressing the guide bar against the wood. Use only light pressure and let the saw do

the work.

•

Maintain a steady speed throughout the cut releasing pressure just before the end of the cut.

•

Know the location of the cord at all times to avoid trip hazards and avoid cutting the cord.

•

Know the location of the tip of the bar at all times and avoid contact with other objects.

•

If the saw stops suddenly when cutting, remove the saw from the cut, then resume cutting using lighter

pressure on the work piece.

Pruning

CAUTION: Falling limbs may bounce or “spring back” after they hit the ground, so it is essential to keep

the ground clear to provide multiple retreat paths. Clear the work area and wear head protection.

Pruning is removing dead or overgrown branches to maintain plant health.

1. Plan retreat paths before beginning to cut, and make sure there are no obstructions. Always know how to get

out of the way of falling branches.

2. Make sure bystanders or helpers are a safe distance from falling branches. Bystanders or helpers should not

stand directly in front of or behind the operator. See Fig. 22.

3. Maintain solid footing and hold the chainsaw firmly with both hands. Do not overreach. Never climb a tree or

ladder to reach high limbs.

4. Secure any branches that might be hazardous.

5. Use proper auxiliary equipment.

6. Prune lower limbs before pruning higher ones.

7. Allow the saw chain to achieve full speed before cutting.

8. Apply light pressure to the branch.

9. For long limbs (Fig. 23), cut the end of the limb first (1) to relieve pressure from the limb, then prune closer to

the trunk (2).

10. Thick limbs (greater than 10 cm (4 inch) in diameter) can splinter or pinch the chain when making a single

cut from the top. To avoid pinching or splintering, first make one shallow relief cut on the bottom surface of

the limb (1), then cut the limb all of the way through from the top of the limb (2) to match the bottom cut (Fig.

24).

SC7 Chainsaw

E&OE © Baumr-AG 24

After most of the limb has been removed, make one smooth cut near the trunk (Fig. 25).

Felling A Tree

CAUTION: A tree is likely to roll or slide downhill after it is felled. Plan and clear a retreat path before

cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of

fall (Fig. 26).

Felling is cutting down a tree.

•

Before felling is started, consider the natural lean of the tree, the location of larger branches and the wind

direction to judge which way the tree will fall.

•

Remove dirt, stones, loose bark, nails, staples, and wire from the tree where felling cuts are to be made.

•

When bucking and felling operations are being performed by two or more persons at the same time,

separate the felling operation from the bucking operation by a distance of at least twice the height of the tree

being felled.

•

Trees should not be felled in a manner that would endanger any person, strike any utility line or cause any

property damage. If the tree contacts any utility line, immediately leave the area, and notify the utility

company.

•

Use the metal spikes on the front of the saw to support the saw on the wood. Set metal spiked bumper into

the wood and use as a leverage point to increase stability when cutting large diameter wood.

Notching Undercut

•

First, make the notch 1/3 the diameter of the tree perpendicular to the direction of fall. Make the lower

horizontal notching undercut first (1). This will help to avoid pinching of either the saw chain or the guide bar

when the second cut (2) is being made (Fig. 27).

Felling Back Cut

•

Second, make the felling back cut at least 50 mm (2 in) higher than the horizontal notching undercut (Fig.

28). Keep the felling back cut parallel to the horizontal notching undercut.

•

Make the felling back cut so enough wood is left to act as a hinge. The hinge wood keeps the tree from

twisting and falling in the wrong direction. Do not cut through the hinge.

•

As the felling cut gets close to the hinge, the tree should begin to fall.

•

If there is any chance that the tree may not fall in the desired direction or it may rock back and bind the saw

chain, stop cutting before the felling back cut is complete and use wedges of wood, plastic, or aluminium to

open the cut and drop the tree along the desired line of fall.

•

When the tree begins to fall, remove the chainsaw from the cut, stop the motor, put the chainsaw down, then

use the retreat path planned.

•

Be alert for overhead limbs falling and watch footing.

Limbing A Tree

CAUTION: Limbs under tension can “spring back” and contact the operator or throw the chainsaw out of

control resulting in personal injury. Always be alert for wood under tension which may strike the

operator or chainsaw when cut.

Limbing is removing the branches from a fallen tree.

•

When limbing, leave larger lower limbs to support the log off the ground.

•

Remove the small limbs in one cut.

•

Branches under tension should be cut from the bottom up to avoid binding the chainsaw (Fig. 29).

Bucking A Log

CAUTION: Bucking logs under tension increases the chance of kickback. Use one of the methods below

to support the log when bucking.

Bucking is cutting a log into lengths. It is important to make sure footing is firm and weight is evenly distributed

on both feet. When possible, the log should be raised and supported by the use of limbs, logs, or chocks.

•

When the log is supported along its entire length, cut from the top (overbuck) (Fig. 30).

•

When the log is supported on one end, cut 1/3 the diameter from the underside (underbuck), then make the

finished cut by overbucking to meet the first cut (Fig. 31).

•

When the log is supported on both ends, cut 1/3 of that diameter from the top overbuck, then make the

finished cut by underbucking the lower 2/3 to meet the first cut (Fig. 32).

•

When bucking on a slope, always stand on the uphill side of the log (Fig. 33).

•

To maintain complete control when cutting through, release the cutting pressure near the end of the cut

without relaxing the grip on the chainsaw handles.

•

Don’t let the chain contact the ground.

•

After completing the cut, wait for the saw chain to stop before you move the chainsaw.

•

Always stop the motor before moving from tree to tree.

BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG

SC7 Chainsaw

•

Make sure the cord and plug are dry before connecting to an outlet.

Tensioning the Saw Chain

IMPORTANT: Only tension the saw chain when the chain is cool. A hot chain may contract and damage

the guide bar or chain as it cools.

If the chain does not touch the underside of the bar when the chainsaw is off and cool, it should be tensioned.

Tension the chain as described in “Tensioning the Saw Chain”.

Sharpening the Saw Chain

It is recommended that an authorised Service Dealer sharpen the chain, but it can also be sharpened by the

operator.

WARNING: If the chain is incorrectly sharpened or the depth gauge is set too low, there is an increased

risk of injury. Always sharpen the chain according to the specifications described in this manual.

IMPORTANT: Sharpening according to these instructions will address minor damage to the saw chain

from contact with dirt or similar occurrences. To repair more serious saw chain damage (such as after

contact with concrete), take the chain to an authorised service dealer, or replace the chain.

Chain sharpening requires these tools:

•

File guide

•

4.5 mm round saw chain sharpening file (use only special saw chain sharpening files)

•

0.025-inch (0.65 mm) depth gauge tool

•

Flat file

After collecting the tools, wear gloves and eye protection, and unplug the chainsaw. Then, file the chain to set

the depth gauge:

1. Loosen the side cover knob and remove side cover.

2. Loosen the chain tensioning ring as far as it will go.

3. Remove the chain.

4. Place the chain in a vise to hold it steady.

5. Place the depth gauge tool on top of the chain so that one depth gauge protrudes through the slot in the tool.

6. If the depth gauge extends above the top of the slot, file the depth gauge down level with the top of the tool

using a flat file (Fig. 31). Never file the depth gauge down enough to exceed the depth gauge setting

specified in this manual.

BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG BAUMR-AG

10. Repeat for each depth gauge on the chain. After setting the depth gauge, sharpen the cutters:

11. Place the chain file into the file guide.

12. Align the file guide so that the correct top plate filing angle marked on the file guide is parallel to the chain

(Fig. 34).

13. Sharpen cutters on one side of the chain first. Make 3-4 strokes with the file from the inside of each cutter to

the outside. Use the same number of strokes on each cutter. Then, turn the chainsaw around and repeat for

cutters on the other side of the chain (Fig. 35).

14. File back any damage on the chrome top or side plates (Fig. 36).

15. Keep all cutter lengths equal.
