GENERAL SAFETY RULES
WARNING:
The warnings, labels and instructions found in this section of the operator’s manual are for your safety. Failure to follow all instructions may result in serious personal injury.
Safe operation of this tool requires that you read and understand this operator’s manual and all labels affixed to the tool. Safety is a combination of using common sense,
staying alert, and knowing how your sa w works.
READ ALL INSTRUCTIONS
Q KNOW YOUR TOOL. Read the operator’s manual
carefully. Learn the saw’s applications and limitations as well as the specific potential hazards related to this tool.
Q CHAINSAWS are designed for cutting wood only.
Q KICK-BACK 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 lightning-fast reverse reaction kicking the guide bar up and back toward 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 ma y 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 the saw. As a chainsaw user, y ou should take several steps to keep cutting jobs free from accident or injury .
1. With a basic understanding of kick-back, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.
2. Keep a good firm grip on the saw with both hands when the engine is running. Place your right hand on the rear handle and your left hand on the front handle with thumbs and fingers encircling the chainsaw handles. A firm grip together with a stiff left arm will help you maintain control of the saw if kick-back occurs.
3. 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 which could be hit while you are operating the saw .
4. Cut at high engine speeds. Always cut with the engine running at full speed. Fully squeeze the throttle trigger and maintain a steady cutting speed.
5. Do not overreach or cut above chest height.
6. Follow the manufacturer’s sharpening and
maintenance instructions for the saw chain.
7. Only use replacement bars and chains specified by the manufacturer or the equivalent.
Q DO NOT OPERATE A CHAINSAW WITH ONE HAND.
Serious injury to the operator, helpers and/or bystanders may result from one-handed operation. A chainsaw is intended for two-handed use.
Q DO NOT OPERATE A CHAINSAW WHEN YOU ARE
FATIGUED. Never operate a chainsa w when you are tired or under the influence of medication, drugs or alcohol.
Q USE SAFETY FOOTWEAR. Wear snug-fitting clothing,
protective gloves and eye, hearing and head protection devices.
Q DO NOT STAND ON ANY UNSTABLE SURFACE while
using your chainsaw. This includes ladders, scaff olding, trees etc.
Q USE CAUTION WHEN HANDLING FUEL. Move the
chainsaw at least 15 m (50 ft) from the refuelling point before starting the engine.
Q DO NOT ALLOW OTHER PERSONS to be near the
chainsaw when starting or cutting with the chainsaw . Keep bystanders and animals out of the w ork area.
Q DO NOT START CUTTING until you have a clear work
area, secure footing and a planned retreat path from the falling tree.

GENERAL SAFETY RULES
Q KEEP ALL PARTS OF YOUR BODY awa y from the saw
chain when the engine is running.
Q ALWAYS CARRY THE CHAINSAW WITH THE ENGINE
STOPPED AND THE BRAKE ENGAGED, the guide bar and saw chain to the rear , and the silencer a wa y from your body . When transporting the chainsaw , use the appropriate guide bar scabbard.
Q DO NOT OPERATE A CHAINSAW THAT IS DAMAGED,
improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.
Q TURN OFF THE ENGINE before putting the chainsaw
down. DO NOT leave the engine running unattended. As an additional safety precaution, apply the chain brake before putting down the sa w.
Q USE EXTREME CAUTION when cutting small-size
brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance.
Q WHEN CUTTING A LIMB under tension, be alert for
spring-back so you will not be struck when the tension in the wood fibres is released.
Q KEEP THE HANDLES dry, clean and free of oil or
fuel mixture.
Q OPERATE THE CHAINSAW ONLY in well ventilated
areas.
Q DO NOT OPERATE A CHAINSAW IN A TREE unless
you have been specifically tr ained to do so.
Q ALL CHAINSAW SERVICE, other than the items listed
in the instruction manual, and all maintenance should be performed by competent chainsaw service personnel. For example , if improper tools are used to remov e the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel may occur and subsequently cause the flywheel to burst.)
Q KEEP ALL PARTS OF YOUR BODY awa y from the saw
chain when the engine is running.
Q KEEP SAFE-T-TIP ANTI-KICK-BACK NOSE GUARD
properly mounted on the guide bar to prevent rotational kick-back.
Q FOLLOW THE SHARPENING and maintenance
instructions for the saw chain.
Q USE ONLY THE REPLACEMENT GUIDE BARS and
low kick-back chains specified for your saw.
Q DO NOT adapt your power head to a bow guide or use it
to power any attachments or devices not listed for your saw.
Q SAVE THESE INSTRUCTIONS. Refer to them
frequently and use to instruct other users. If you lend someone this tool, lend them these instructions too.

SPECIFIC SAFETY RULES
WARNING:
The warnings, labels and instructions found in this section of the operator’s manual are for your safety. Failure to follow all instructions may result in serious personal injury.
GENERAL PRECAUTIONS
Q DO NOT CUT VINES and/or small underbrush less than
76 mm (3 in.) in diameter.
Q SILENCER SURFACES ARE VERY HOT during and
after operation of the chainsaw; keep all body parts away from the silencer. Serious burns may occur if contact is made with the silencer.
QALWAYS HOLD THE CHAINSAW WITH BOTH HANDS
when the engine is running. Use a firm grip with thumbs and fingers encircling the chainsaw handles.
Q NEVER LET ANYONE USE YOUR CHAINSAW who has
not received adequate instructions in its proper use. This applies to hired as well as privately owned saws.
Q BEFORE YOU START THE ENGINE, make sure the
saw chain is not contacting any object.
Q OPERATE THE CHAINSAW only in well ventilated areas.
SAFETY APPAREL
Q Wear snug-fitting clothing. Always wear heavy, long
trousers, boots and gloves. Do not wear jewellery, shorts, sandals, or go barefoot. Do not wear loose fitting clothing which could be drawn into the engine or catch the chain or underbrush. Wear overalls, jeans or chaps made of cut-resistant material or ones that contain cut-resistant inserts. Secure hair so that it is above shoulder level.
Q Wear non-slip safety footwear and heavy-duty gloves to
improve your grip and to protect your hands.
Q Wear eye, hearing and head protection when operating
this equipment.
REFUELLING (DO NOT SMOKE!)
Q To reduce the risk of fire and burn injury, handle fuel with
care. It is highly flammable.
Q Mix and store fuel in a container approved for petrol.
Q Mix fuel outdoors where there are no sparks or flames.
Q Select bare ground, stop the engine, and allow it to cool
before refuelling.
Q Loosen the fuel cap slowly to release pressure and to

MAINTENANCE PRECAUTIONS
Never operate a chainsaw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released. If the saw chain moves at idling speed, the carburettor may need adjusting. Refer to “Operation” later in this manual. If the saw chain still moves at idling speed after adjustment has been made, contact a Homelite service dealer for adjustment and discontinue use until the repair is made.
WARNING:
All chainsaw service, other than items in the operator’s manual maintenance instructions, should be performed by competent chainsaw service personnel. If improper tools are used to remove the flywheel or clutch, or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur which could subsequently cause the flywheel to burst with possible serious injury.
KICK-BACK
Kick-back is a dangerous reaction which may lead to serious injury. Do not rely only on the safety devices provided with your saw. As a chainsa w user, you must take special safety precautions to help keep your cutting jobs free from accident or injury .
NOTE: See the “Operation” section later in this manual for added information on kick-back and how to avoid serious personal injury .
NOTE: Your chainsaw has been fully factory tested. It is normal to find some slight oil residue on the saw.

LOW KICK-BACK SAW CHAIN
The rakers (depth gauges) ahead of each cutter can minimise the force of a kick-back reaction by preventing the cutters from digging in too deeply at the kick-back zone. Only use replacement chain which is equivalent to the original chain or has been certified as a low kick-back chain.
As saw chains are sharpened, they lose some of the low kick-back qualities and extra caution is required.
WARNING:
The warnings and instructions in this section of the operator’s manual are for your safety and to prevent serious personal injury.
UNDERSTANDING YOUR CHAINSAW SAFETY DEVICES
SAFE-T-TIP® ANTI-KICK-BACK NOSE GUARD
The SAFE-T-TIP® prevents kick-back because it covers the tip of the bar where rotational kick-back is generated. Inexperienced persons should never attempt to cut when the SAFE-T-TIP® has been removed from the bar tip .
GUIDE BARS
Generally , guide bars with small r adius tips hav e somewhat lower kick-back potentials.
When making a replacement, be sure to order one of the Homelite bars listed for your saw in this operator’s manual. The proper size SAFE-T-TIP on the bar. Use only guide bars that have a provision for mounting the SAFE-T-TIP®.

OPERATION
CHAIN BRAKE
Chain brakes are designed to quickly stop the chain from rotating. When the chain brake lever/hand guard is pushed towards the bar, the chain should stop immediately. A chain brake does not prevent kick-back.
The chain brake should be cleaned and tested daily. Refer to “Operation” later in this manual for additional information.
WARNING:
Even with daily cleaning of the mechanism, the dependability of a chain brake to perform under field conditions cannot be certified. Keep the SAFE-T-TIP nose guard on the saw guide bar and use proper cutting techniques.
RUN POSITION
WARNING:
KICK-BACK occurs 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 towards 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 may cause loss of saw control which can result in serious injury.
Do not rely exclusively upon the safety devices built into the saw. As a chainsaw user, you should take several steps to keep your cutting jobs free from accident or injury.
KICK-BACK PRECAUTIONS
Rotational kick-back occurs when the moving chain con­tacts an object at the Kick-back Danger Zone of the guide bar. The result is a lightning-f ast, rev erse reaction which kicks the guide bar up and back tow ards the operator . This reaction may cause loss of control which can result in serious injury.
