of these persons may result from one-handed operation. A chain saw is intended for two-
handed use.
Avoid body contact with grounded surfaces such as metal pipes and wire fences. There is an
increased risk of electric shock if your body is grounded.
Do not operate a chain saw that is damaged, improperly adjusted, or not completely and
securely assembled. Chain should slow to a stop when the switch trigger is released. If the
chain continues to turn after the switch trigger has been released, have the unit serviced by
your nearest GREENWORKS service dealer.
Check for damaged parts. Check for alignment of moving parts, binding of moving parts,
breakage of parts, mounting, and any other conditions that may affect its operation. A guard
or other part that is damaged should be properly repaired or replaced by an authorized
service dealer unless otherwise indicated elsewhere in this m
anual.
All chain saw service, other than the items listed in the operation and maintenance sections,
should be performed by your nearest GREENWORKS service dealer.
Always maintain a proper stance.
Do not use chain saw if switch does not turn it on and off. Have defective switch replaced by
aut
horized service centre.
Remove the battery when not in use, before servicing, and when making adjustments and
changing attachments, such as saw chain and guard.
Do not cut vines and/or small underb
rush.
Do not operate a chain saw in a tree, on a ladder, or scaffold; this is extremely dangerous.
NOTE: The size of the work area depends on the job being performed as well as the size tree or work piece
involved. For example, felling a tree requires a larger work area than making bucking cuts.
Use extreme caution when cutting small size brush and saplings, because small material may
catch the saw chain and be whipped toward you or pull you off balance.

SAFETY INFORMATION
WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities
contains chemicals known to cause cancer, birth defects or other reproductive harm. Some
examples of these chemicals are:
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well- ventilated area, and work with approved safety
6
SAFETY INFORMATION
KICKBACK (See Figure 1-2)
WARNING
Kickback may occur when the moving chain contacts an object at the upper portion of the tip of the
guide bar or when the wood closes in and pinches the saw chain in the cut. Contact at the upper
portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for
an instant. The result is a lightning fast, reverse reaction which kicks the guide bar up and back
toward the operator. If the saw chain is pinched along the top of the guide bar, the guide bar can
be driven rapidly back toward the operator. Either of these reactions can cause loss of saw control
which can result in s
erious injury. Do not rely exclusively upon the safety devices built into the saw.
As a chain saw user, you should take several steps to keep your cutting jobs free from accident or
injury.
The following precautions should be followed to minimize kickback:
1.
unit is running. Place your right hand on the rear handle and your left hand on the front
with a stiff left arm will help you maintain control of the saw if kickback occurs.
2. Make sure that the area in which you are cutting is free from obstructions. Do not let the
nose of the guide bar contact a log, branch, fence, or any other obstruction that could be
hit while you are operating the saw.
3. Always cut with the unit running. Fully squeeze the switch trigger and maintain cutting
speed.
4. Use only the replacement guide bars and low kickback chains specified by the
manufacturer for the saw.
With a basic understanding of kickback, you can reduce or eliminate the element of surprise.
Sudden surprise contributes to accidents.
Keep proper footing and balance at all times.
Do not cut above shoulder height or overreach when cutting.
Follow the sharpening and maintenance instructions for the saw chain.

SAFETY INFORMATION
Push and Pull - This reaction force is always opposite to the direction the chain is moving
where wood contact is made. Thus, the operator must be ready to control the PULL
when cutting on the bottom edge of the bar, and PUSH when cutting along the top edge.
(See Figure 3)
UNDERSTANDING YOUR CHAIN SAW SAFETY DEVICES (See Figure 4)
LOW KICKBACK SAW CHAIN
The rakers (depth gauges) ahead of each cutter can minimize the force of a kickback reaction
by preventing the cutters from digging in too deeply at the kickback zone. Only use replacement
B175.1. Low kickback/skip tooth saw chain is a chain that has met the kickback performance
requirements of ANSI B175.1 - 1991 (American National Standard for Power Tools - Gasoline-
Powered Chain Saws-Safety Requirements) when tested on the representative sample of chain
useful life, they lose some of the low kickback qualities and extra caution should be used.

BASIC OPERATING/CUTTING PROCEDURES
Practice cutting a few small logs using the following technique to get the “feel” of using the saw
Take the proper stance in front of the wood with the saw idling.
Press the switch lock and squeeze the switch trigger then release switch lock and let the
chain accelerate to full speed before entering the cut.
Begin cutting with the saw against the log.
Keep the unit running the entire time you are cutting, maintain a steady speed.
Allow the chain to cut for you; exert only light downward pressure. Forcing the cut could result
in damage to the bar, chain, or motor.
Release the switch trigger as soon as the cut is completed, allowing the chain to stop. If you
run the saw without a cutting load, unnecessary wear can occur to the chain, bar, and unit.
Do not put pressure on the saw at the end of the cut.
WORK AREA PRECAUTIONS
(See Figure 11)
Cut only wood or materials made from wood; no sheet metal, no plastics, no masonry, no non-
wood building materials.
Never allow children to operate the saw. Allow no person to use this chain saw who has not
read this operator’s manual or received adequate instructions for the safe and proper use of
this chain saw.
Keep everyone – helpers, bystanders, children, and animals – a SAFE DISTANCE from the
cutting area. During felling operations, the safe distance should be a least twice the height of
the largest trees in the felling area. During bucking operations, keep a minimum distance of
15' (4.6 m) between workers.
Always cut with both feet on solid ground to prevent being pulled off balance.
Do not cut above chest height as a saw held higher is difficult to control against kickback
forces.
Do not fell trees near electrical wires or buildings. Leave this operation for professionals.
Cut only when visibility and light are adequate for you to see clearly.

FELLING TREES
HAZARDOUS CONDITIONS
WARNING
Do not fell trees during periods of high wind or heavy precipitation. Wait until the hazardous
weather has ended.
When felling a tree, it is important that you heed the following warnings to prevent possible
Do not cut down trees having an extreme lean or large trees with rotten limbs, loose bark,
or hollow trunks. Have these trees pushed or dragged down with heavy equipment, then cut
them up.
Do not cut trees near electrical wires or buildings.
Check the tree for damaged or dead branches that could fall and hit you during felling.
Periodically glance at the top of the tree during the backcut to assure the tree is going to fall in
the desired direction.
If the tree starts to fall in the wrong direction, or if the saw gets caught or hung up during the
fall, leave the saw and save yourself!
OPERATING YOUR CHAIN SAW
21
PROPER PROCEDURE FOR TREE FELLING
(See Figure 12-15)
Felling a tree — When bucking and felling operations are being performed by two or more
persons, at the same time, the felling operation should be separated 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 does make contact with any utility line, the utility company should
Operator should keep on the uphill side of terrain as the tree is likely to roll or slide after it is
felled.
Pick your escape route (or routes in case the intended route is blocked). Clear the immediate
area around the tree and make sure there are no obstructions in your planned path of retreat.
Clear the path of safe retreat approximately 135° from the planned line of fall.
Consider the force and direction of the wind, the lean and balance of the tree, and the location
tree along a line different from its natural line of fall.
Remove dirt, stones, loose bark, nails, staples, and wire from the tree where felling cuts are to
be made.
Notched Undercut. Cut a notch about 1/3 the diameter of the trunk in the side of the tree.
Make the notch cuts so they intersect at a right angle to the line of fall. This notch should be
cleaned out to leave a straight line. To keep the weight of the wood off the saw, always make
the lower cut of the notch before the upper cut.
Felling Backcut. As the felling cut gets close to the hinge the tree should begin to fall. If there
is any chance the tree may not fall in the desired direction or it may rock back and bind the
saw chain, stop cutting before the felling cut is complete and use wedges of wood, plastic or
aluminum to open the cut and drop the tree along its desired line of fall. Make the backcut
level and horizontal, and at a minimum of 2" (5 cm) above the horizontal cut of the notch.

NOTE: Never cut through to the notch. Always leave a band of wood between the notch and back cut (ap-
proximately 2" (5 cm) or 1/10 the diameter of the tree). This is called “hinge” or “hingewood.” It controls the fall
of the tree and prevents slipping or twisting or shoot back of the tree off the stump.
On large diameter trees, stop the back cut before it is deep enough for the tree to either fall
or settle back on the stump. Then insert soft wooden or plastic wedges into the cut so they do
As tree starts to fall, stop the chain saw and put it down immediately. Retreat along the
cleared path, but watch the action in case something falls your way.

REMOVING BUTTRESS ROOTS
(See Figure 16)
A buttress root is a large root extending from the trunk of the tree above the ground. Remove
vertical cut. Remove the resulting loose section from the work area. Follow the correct tree felling
procedure as stated in Proper Procedure For Tree Felling after you have removed the large
buttress roots.
BUCKING
(See Figure 17)
Bucking is the term used for cutting a fallen tree to the desired log length.
Always make sure your footing is secure and your weight is distributed evenly on both feet.
Cut only one log at a time.
Support small logs on a saw horse or another log while bucking.
Keep a clear cutting area. Make sure that no objects can contact the guide bar nose and
chain during cutting, this can cause kickback. Refer to Kickback earlier in this manual.
When bu
cking on a slope, always stand on the uphill side of the log. To maintain complete
control of the chain saw when cutting through the log, release the cutting pressure near the
end of the cut without relaxing your grip on the chain saw handles. Do not let the chain contact
the ground. After completing the cut, wait for the saw chain to stop before you move the chain

BUCKING WITH A WEDGE
(See Figure 18)
If the wood diameter is large enough for you to insert a soft bucking wedge without touching the
chain, you should use the wedge to hold the cut open to prevent pinching.
BUCKING LOGS UNDER STRESS
(See Figure 19)
When the log is supported on one end, cut 1/3 the diameter from the underside. Then make the
finished cut by overbucking to meet the first cut.
When the log is supported on bothe edn, cut 1/3 of the diameter from the top overback. Then
make the finished cut by under bucking the lower 2/3 to meet the first cut.
OVERBUCKING
(See Figure 20)
Begin on the top side of the log with the bottom of the saw against the log; exert light pressure
downward. Note that the saw will tend to pull away from you.
UNDERBUCKING
(See Figure 21)
Begin on the under side of the log with the top of the saw against the log; exert light pressure
upward. During under bucking, the saw will tend to push back at you. Be prepared for this

Leave the larger support limbs under the tree to keep the tree off the ground while cutting.
Limbs should be cut one at a time. Remove the cut limbs from the work area often to help
keep the work area clean and safe.
Branches under tension should be cut from the bottom up to avoid binding the chain saw.

CUTTING SPRINGPOLES
When bucking on a slope always stand on the uphill side of the log. when cutting through to maintain
complete control release the cutting pressure near the end of the cut without relaxing your grip on the
chainsaw handle. 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.
(See Figure 24)
A springpole is any log, branch, rooted stump, or sapling which is bent under tension by other
wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted
stump has a high potential of springing back to the upright position during the bucking cut to
separate the log from the stump. Watch out for springpoles — they are dangerous.
WARNING
Springpoles are dangerous and could strike the operator, causing the operator to lose control of the
chain saw. This could result in severe or fatal injury to the operator.

NOTE: When placing the bar on the bar studs, ensure that the adjusting pin is in the chain tension pin hole.
Replace the chain cover.
Replace the sleeve and chain cover lock bolt; use a hexagon ring spanner to rotate bolt
Remove all slack from the chain by turning the chain tensioning bolt clockwise with a hexagon
ring spanner until the chain seats snugly against the bar with the drive links in the bar groove.
Lift the tip of the guide bar up to check for sag.
Release the tip of the guide bar and turn the chain tensioning bolt 1/2 turn clockwise. Repeat
this process until sag does not exist.
Hold the tip of the guide bar up and tighten the chain cover lock bolt. The chain is correctly
tensioned when there is no sag on the underside of the guide bar, the chain is snug, but it can
be turned by hand without binding.
NOTE: If chain is too tight, it will not rotate. Loosen the chain cover lock bolt slightly and turn the chain ten-
sioning bolt 1/4 turn counterclockwise. Lift the tip of the guide bar up and retighten the chain cover lock bolt.
Ensure that the chain will rotate without binding.

NOTE: During normal saw operation, the temperature of the chain increases. The drive links of a correctly
tensioned warm chain will hang approximately 1/16" (1.3 mm) out of the bar groove.
NOTE: New chains tend to stretch; check the chain tension frequently and tension as required.
CAUTION
A chain tensioned while warm may be too tight upon cooling. Check the “cold tension” before
next use.

MAINTENANCE
CHAIN MAINTENANCE
(See Figure 37)
Use only a low-kickback chain on this saw. This fast-cutting chain provides kickback reduction
when properly maintained. For smooth and fast cutting, maintain the chain properly. The chain
requires sharpening when the wood chips are small and powdery, the chain must be forced
through the wood during cutting, or the chain cuts to one side. During maintenance of the chain,
consider the following:
Raker (depth gauge) clearance.
Too low increases the potential for kickback.
Not low enough decreases cutting ability.
the wood, have an authorized service center sharpen the chain.
NOTE: Inspect the drive sprocket for wear or damage when replacing the chain. If signs of wear or damage
are present in the areas indicated, have the drive sprocket replaced by an authorized service center.
NOTE: If you do not fully understand the correct procedure for sharpening the chain after reading the instruc-
tions that follow, have the saw chain sharpened by an authorized service centre or replace with a recom-
mended low-kickback chain.

CAUTION
Make sure the battery is removed from the chain saw before you work on the saw.
WARNING
The saw chain is very sharp. Always wear protective gloves when performing maintenance to

CAUTION
A dull or improperly sharpened chain can cause excessive motor speed during cutting, which
may result in severe motor damage.
WARNING
Improper chain sharpening increases the potential of kickback.

MAINTAINING THE GUIDE BAR
(See Figure 47)
Every week of use, reverse the guide bar on the saw to distribute the wear for maximum
bar life. The bar should be cleaned every day of use and checked for wear and damage.
Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be
smoothed with a file as soon as they occur. A bar with any of the following faults should be
replaced:
Wear inside the bar rails that permits the chain to lay over sideways
Bent guide bar
Cracked or broken rails
Spread rails
Lubricate guide bars weekly with a sprocket at their tip. Using a grease syringe, lubricate weekly
in the lubricating hole. Turn the guide bar and check that the lubrication holes and chain groove
are free from impurities.
