GENERAL SAFETY RULES

guide bar and saw chain to the rear, and the muffler away from your body. When transporting the chain saw, use the appropriate guide bar scabbard.

Do not operate a chain saw 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.

■Shut off the engine before setting the chain saw down. Do not leave the engine running unattended. As an additional safety precaution, apply the chain brake prior to setting 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 that is under tension, be alert for springback so that you will not be struck when the tension in the wood fibers is released.

■Keep the handles dry, clean, and free of oil or fuel mixture.

Beware of carbon monoxide poisoning. Operate the chain saw only in well-ventilated areas.

■Do not operate a chain saw in a tree unless you have been specifically trained to do so.

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

All chain saw service, other than the items listed in the instruction manual and all maintenance, should be performed by competent chain saw 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 could cause the flywheel to burst.)

Always have a fire extinguisher available when using chain saw.

Use only the replacement guide bars and low kickback chains specified for the saw.

■Do not adapt the powerhead to a bow guide

or use it to power any attachments or devices not listed for the saw.

■The gas powered saw (or electrically powered saw) is classified by CSA as a Class 1C (or Class 2C) saw. It is intended for

infrequent use by homeowners, cottagers,­ and campers, and for such general applications as clearing, pruning, cutting firewood, etc. It is not intended for prolonged use. Prolonged periods of operation can cause circulatory problems in the user’s hands due to vibration. For such use, it may be appropriate to use a saw having an anti-vibration feature.

Save these instructions. Refer to them frequently and use to instruct other users. If you loan someone this product, loan 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.

Do not cut vines and/or small underbrush (a diameter of less than 3 in.).

Muffler surfaces are very hot during and after operation of the chain saw; keep all body parts

away from the muffler. Serious burns may occur if contact is made with the muffler.

■Always hold the chain saw with both hands when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles.

■Never let anyone use the chain saw who has not received adequate instructions in its proper use. This applies to rentals as well as privately owned saws.
