5.1 GENERAL POWER TOOL SAFETY WARNINGS
WARNING Read all safety warnings, instructions, illustrations and specifications provided
with this power tool. Failure to follow all instructions listed below may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions for future reference.
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
Work area safety
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control.
Electrical safety
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets
will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
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 residual current device
(RCD) protected supply. Use of an RCD 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 a 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. This enables better control of
the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair and clothing 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 remove 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 and accessories. 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.
5.2 GENERAL SAFETY INSTRUCTIONS FOR CHAINSAW USE
Chainsaws pose a very significant health and safety risk, even to careful and informed operators,
for example, the use of a chainsaw in the workplace requires extensive training and certification.
The dangers of using and applying a chainsaw should not be taken lightly. Seek guidance, training
or employ a professional to carry out the task if uncertain or nervous of the potential risks and
dangers involved.
Warning: Danger of death.
Personal Protective Equipment (PPE)
– Due to the nature and ferocity of a petrol driven
chainsaw, no PPE equipment can provide 100%
protection against chainsaw cuts.
– Equipment specifically designed for use with a chainsaw shall be worn, consisting of;
• Safety helmet (EN 397).
• Mesh visor (EN 1731).
• Hearing protection (EN 352).
• Gloves (EN 381-7) with protective guard on back of left hand.
• Leg protection (EN 381-5).
• Non-slip boots (EN 345-2).
• High visibility jacket.
Leg protection is achieved with a chain clogging material designed to stop the chain before it
penetrates fully through and into flesh.
The gloves, boots and leg protection should be marked
with the symbol (right) and indicate the chain speed to
which they have been tested.
Preparation
– Before use inspect the guide bar grooves for distortion, the guide bar rail for cracks, the nose
sprocket teeth condition, chain tension and condition, drive sprocket condition and operation
and operation of the chain brake.
– Never operate the chainsaw alone in case of emergency. Have an assistant in
visual/communicative range.
– Ensure the site is assessed for potential risk and a safe working distance is marked to prevent
bystanders entering.
– In case of accident, ensure means of contact with emergency services are possible and
adequate information is available to facilitate an urgent recovery.
– Always carry a basic first aid kit containing large wound dressings.
– Identify all services (e.g. gas, water, electric, phone etc.), particularly overhead before felling
commences.
– Ensure a distance of at least twice the tree height is observed from all obstacles and dangers.
– Keep bystanders a minimum of 10M away and all access points into the work area marked
accordingly.
– Tree felling must only be carried out by a single individual and only after the danger zones and
escape routes have been identified and cleared.
– Do not fell when wind conditions may influence/control the direction.
– Close observation and inspection for dead or diseased wood and insecure limbs or branches
must be carried out prior to any cutting. Dead wood can cause unexpected reactions during a
routine felling.
– Remove any scrub or other obstructions from the area to enable a quick escape route and
ensure visibility of the chain is not impeded during cutting.
– Plan work to reduce manual lifting, i.e. lightest off cuts move furthest.
– If work is a result of wind blow, ensure no unstable trees or limbs pose any further danger.
– Never stand on anything other than the ground.
– When preparing to work on the ground, e.g. cross cutting or limbing, ensure no obstacles are
hidden or obscured from view. Contact with such an object can result in loss of footing or
kickback from the chainsaw.
Saw operation
– Do not operate the chainsaw without being completely familiar on all safety aspects, functions
and most importantly how to stop the chainsaw in an emergency.
– Do not operate the chainsaw above shoulder height.
– Regularly clear cut material as build up will create a hazard under foot.
– Never use the chainsaw if the stop switch is FAULTY or not functional.
– Prior to each use inspect the chainsaw for damage. Ensure all safety features and
mechanisms function correctly and that the cutting means is of the type and design as
specified by the manufacturer.
– Adopt a secure and balanced stance, bend knees instead of back. Hold the saw close into
your body for balance.
– Maintain a good grip with both hands on the saw. The chainsaw is solely designed for
operation of the rear handle by the right hand and the left hand on the front handle. Grip the
front handle with left thumb underneath to allow resistance in case of kickback.
– Stop the chainsaw before setting it aside.
– Only begin cutting with throttle at maximum.
– Kickback occurs when the chainsaw is stopped suddenly resulting in the tip or the guide bar
being violently thrown up towards the operator’s head/face. Correct stance and knowledge of
the operating procedure can greatly reduce that risk.
– Operate the chain brake before moving with the saw. If moving more than a short distance,
stop the saw and refit the bar guard.
– Warning: during and after use, take care not to touch the hot engine parts, in particular the
exhaust muffler.
– Do not attempt to use the chainsaw if tired, ill or under the influence of alcohol or other drugs.
Felling
– Remove lower branches/limbs from the tree up to shoulder height.
– When removing the lower branches ensure the operator is protected from kickback by using
the tree stem for protection and keeping the guide bar out of line with the body (off set).
– Ensure there is sufficient fuel in the tank to safely complete the felling cut.
– Never leave a partially felled tree.
– When the tree begins to fall move back and away at 45º as quickly as possible. Branches on
the underside of the tree can cause the stem to move sideways or backwards dangerously.
– In the event of a tree becoming hung in another tree or obstacle seek assistance from a
professional. A hung tree poses many dangers and creates more potential risks than felling a
normal tree. Do not abandon a hung tree, walk under or attempt to climb one.
– Always perform a notch cut followed by a felling cut to create a felling hinge. Felling wedges or
levers may be necessary to prevent the chainsaw from becoming pinched in the felling cut.
Limbing
– Ensure the tree is stable before any limbering commences.
– The ideal working height for performing limbing is between waist and knee height.
– Stand on the left side of the stem, working from the root upwards, then return down the other
side.
– Use the top (pushing chain) and bottom (pulling chain) to make the cuts, constantly taking
note of the bar tip in conjunction with limbs further round the stem which may be less visible or
obscured.
– Ensure the tip of the bar does not come into contact with the ground.
– If the felled tree is on a slope always remain above the tree in case the removal of a limb were
to cause potentially dangerous movement.
– Rest the weight of the saw on the tree where possible.
– Take care of limbs and undergrowth under tension as there is a danger of spring back once
the cut has been performed.
– At regular intervals, stop the chainsaw and clear the cut debris to maintain a firm footing.
Cross cutting
– The timber must be raised off the ground with supports to perform a safe cut.
– When working on slopes, always work above the timber in case of movement.
– Always adopt a good firm footing.
– Observe the timber to assess the surfaces for tension.
– Tension and compression in supported timber can result in the timber splitting or pinching the
guide bar if incorrectly cut.
– Alleviate tension in the timber by making an initial cut (1/3) into the compressed surface
before finishing the cut (2/3) into the tension surface.
– Stand off to the side of the saw in case of kickback.
– If the chainsaw becomes trapped, switch off immediately before attempting to free the guide
bar. Use the correct tools when attempting to free a trapped saw.
– Be ready to step back quickly in case of the timber rolling.
– Ensure no debris is present in the work area.
Maintenance
– Never modify the chainsaw in anyway.
– Always maintain the chainsaw in good working order regularly serviced by an authorised
service agent.
– Ensure the handles remain clean and free from oil, fuel & moisture.
– Only use replacement parts supplied by the manufacturer.
– Ensure the chain does not rotate while the saw is at idle.
– All safety devices must remain fitted, functioning and where possible serviced. Especially the
chain brake.
– Only use fresh, clean and good quality fuel/oil mix in the chainsaw.
– Regularly inspect the chain lubricant level, regularly topping up. When the chainsaw is running
at high speed the chain oil will dispel quicker and require checking/adjusting more frequently.
– Never operate the chainsaw without chain oil.
– Never operate the chainsaw with a maladjusted or blunt chain as this is highly dangerous.
– When the chainsaw has warmed up, stop the chain & engine before checking/adjusting the
tension.
– Never refuel in close proximity to naked flames, sparks or other sources of ignition, e.g.
cigarettes.
– Allow the engine to cool before refuelling. Avoid spillage while refuelling.
– Wipe up and correctly dispose of any fuel spillage immediately with a suitable medium.
– Ensure the correct ratio of fuel and oil are used.
– Do not set down a hot chainsaw on or near easily combustible materials. e.g. dry leaves and
grass.
– Move away from the refuelling area before restarting the chainsaw.
– Store fuel for short periods only and avoid mixing more than is required. Store in a container
specifically designed for petrochemical applications away from heat and direct sun light.
– Prior to use check for chain oil distribution on a piece of paper or cut timber. Observe spatter
before continuing.
– After each use clean the chainsaw thoroughly.
– Regularly check external nuts and fixings to ensure vibration caused by normal use has not
begun to loosen them.
– Periodically remove all shavings and sawdust from the visible parts of the chain brake
mechanisms.
9. OPERATING INSTRUCTIONS
Storage
– Thoroughly clean/service the chainsaw and refit the bar guard. Remove the spark plug
ignition lead from the back of the spark plug and position the lead to avoid accidental
reconnection.
– Locate the machine out the reach of children, in a dry locked unit.
– Remove all residual fuel from the fuel tank before storing.
5.2 HEALTH AND SAFETY INFORMATION CONCERNING THE USE OF
FUELS
Fuels are inflammable and explosive. Reduce the risk of explosion and fire by:
– Turning off and cooling the motor down before filling the tank with fuel.
– Refraining from smoking and starting open fires when handling fuels.
– Storing and mixing fuels in approved and correspondingly labelled canisters.
– Storing fuels in closed containers. Keeping in mind that fuels may evaporate at room
temperature and collect on the floor of closed rooms (risk of explosion).
Fuels are toxic, they contain substances that have an immediate toxic effect and may cause
permanent damage to your health. Take all precautionary measures to prevent your body
from absorbing any of these substances:
– Tank and siphon fuels only outdoors or in well-ventilated rooms.
– Do not inhale fuel fumes.
– Avoid contact with eyes and skin.
– Wear gloves when transferring fuel.
– When fuel has come into contact with your clothes, change them immediately. Clean your
clothes before putting them back on.
– Store fuels out of the reach of children.
When handled inappropriately, fuels may cause damage to the environment:
– Transfer fuel carefully. Fuel must never trickle into the ground or the sewage system.
– Dispose of any remaining fuel in an appropriate manner. Never dispose of fuel with regular
household waste.
– Fuels may be stored only for a limited time. Purchase only such quantities that can be used up
within a few months.
9.14 SHARPENING (FIG.34)
– Sawdust instead of chips is an indication that the
saw chain needs sharpening, or replacing.
– Before sharpening, the chain must be made taught
by means of the chain tensioner.
– After sharpening, slacken and adjust the chain as
per the mounting instructions.
– During sharpening, lock the chain using the brake.
– Use a round file specific for the chain fitted.
Observe the sharpening angle (Fig. 29 parts
2,3,5,6).
– Sharpen by filing from the inside outwards (Fig. 29
part 1) all the teeth on one side and then all the
teeth on the other.
– Position the file to project 20% of its diameter
above the cutter (Fig 29 part 4).
– Make sure every cutter is filed to the same length
and angle and that all depth gauge links are the
same height.
– Inconsistent angles can result in a poor cut or
endanger the user. Seek advice from a
professional if unsure.
FIG.33
FIG.34
9.13 CHAIN LUBRICATION (FIG.33)
– Prior to use check for chain oil distribution on a
piece of paper or cut timber. Observe spatter
before continuing.
– If the chain is not sufficiently lubricated, increase
the oil flow by rotating the setting screw (32) of the
pump anti-clockwise.
