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 saw works.

READ ALL INSTRUCTIONS

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.

CHAINSAWS are designed for cutting wood only.

KICK-BACK MAY OCCURWHENTHE NOSE ORTIP 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 toward 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 upon the safety devices built into your saw. As a chainsaw user, you should take several steps to keep your 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 your 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 that 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.Use only replacement bars and chains specified by the manufacturer or the equivalent.

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.

DO NOT OPERATE A CHAINSAW WHENYOU ARE FATIGUED. Never operate a chainsaw when you are tired or under the influence of medication, drugs, or alcohol.

USE SAFETY FOOTWEAR. Wear snug-fitting clothing, protective gloves, and eye, hearing, and head protection devices.

DO NOT STAND ON ANY UNSTABLE SURFACE while using your chainsaw: that includes ladders, scaffolds, trees, etc.

USE CAUTION WHEN HANDLING FUEL. Move the chainsaw at least 50 feet (15 m) from the refuelling point before starting the engine.

DO NOT ALLOW OTHER PERSONS to be near the chainsaw when starting or cutting with the chainsaw. Keep bystanders and animals out of the work area.

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

KEEP ALL PARTS OF YOUR BODY away from the saw chain when the engine is running.

ALWAYS CARRYTHE CHAINSAW WITHTHE ENGINE STOPPED ANDTHE BRAKE ENGAGED, the guide bar and saw chain to the rear, and the silencer away from your body. When transporting the chainsaw, use the appropriate guide bar scabbard.

DO NOT OPERATE A CHAINSAWTHAT 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.

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 saw.

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.

WHEN CUTTING A LIMB under tension, be alert for spring-back so that you will not be struck when the tension in the wood fibres is released.

KEEP THE HANDLES dry, clean, and free of oil or fuel mixture.

OPERATETHE CHAINSAW ONLY in well-ventilated areas.

DO NOT OPERATE A CHAINSAW IN ATREE unless you have been specifically trained to do so.

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 remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and subsequently cause the flywheel to burst.)

KEEP SAFE-T-TIP® ANTI-KICK-BACK NOSE GUARD properly mounted on the guide bar to prevent rotational kick-back.

FOLLOW THE SHARPENING and maintenance instructions for the saw chain.

USE ONLY THE REPLACEMENT GUIDE BARS and low kick-back chains specified for your saw.

DO NOT adapt your powerhead to a bow guide or use it to power any attachments or devices not listed for your saw.

SAVE THESE INSTRUCTIONS. Refer to them frequently and use to instruct other users. If you lend someone this tool, lend them these instructions also.

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

DO NOT CUT VINES and/or small undergrowth (less than 76 mm (3 in.) in diameter).

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.

ALWAYS HOLDTHE CHAINSAWWITH BOTH HANDS when the engine is running. Use a firm grip with thumbs and fingers encircling the chainsaw handles.

NEVER LET ANYONE USE YOUR CHAINSAW who has not received adequate instructions in its proper use. This applies to rentals as well as privately owned saws.

BEFORE YOU START THE ENGINE, make sure the saw chain is not contacting any object.

OPERATE THE CHAINSAW only in well ventilated areas.

SPECIFIC SAFETY RULES

PROPER CLOTHING FOR SAFETY

Wear close-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 undergrowth. Wear overalls, jeans, or leggings made of cut-resistant material or ones that contain cut-resistant inserts. Secure hair so that it is above shoulder level.

Wear non-slip safety footwear and heavy-duty gloves to improve your grip and to protect your hands.

Wear eye, hearing, and head protection when operating this equipment.

REFUELLING (DO NOT SMOKE!)

To reduce the risk of fire and burn injury, handle fuel with care. It is highly flammable.

Mix and store fuel in a container approved for petrol.

Mix fuel outdoors where there are no sparks or flames.

Select bare ground, stop the engine, and allow it to cool before refuelling.

Loosen the fuel cap slowly to release pressure and to keep fuel from escaping around the cap.

Tighten the fuel cap securely after refuelling.

Wipe spilled fuel from the unit. Move 15 m (50 ft.) away from refuelling site before starting engine.

Never attempt to burn off spilled fuel under any circumstances.

BASIC PRECAUTIONS IN THE CUTTING/ WORK AREA

Do not operate a chainsaw in a tree.

Do not cut from a ladder: this is extremely dangerous.

Keep bystanders and animals out of the work area.

Do not allow other persons to be nearby during starting or cutting with the chainsaw.

NOTE: The size of the work area depends on the job being performed as well as the size tree or workpiece involved. For example, felling a tree requires a larger work area than making other cuts, i.e., bucking

cuts, etc.

PUSH AND PULL

The reaction force is always opposite to the direction the chain is moving. Thus, the operator must be ready to control the PULL when cutting on the bottom edge of the bar and the PUSH when cutting along the top edge.

NOTE: Your chainsaw has been fully factory tested. It is normal to find some slight oil residue on the saw.

MAINTENANCE PRECAUTIONS

Never operate a chainsaw that is damaged, improperly adjusted, or is 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 – Adjusting Idling Speed” later in this manual. If the saw chain still moves at idling speed after adjustment has been made, contact a Ryobi 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 and serious injury could result.

KICK-BACK

Kick-back is a dangerous reaction that can lead to serious injury. Do not rely only on the safety devices provided with your saw. As a chainsaw user, you must take special safety precautions to help keep your cutting jobs free from accident or injury.

NOTE: Refer to “Operation” later in this manual for added information on kick-back and how to avoid serious personal injury.
