RULES FOR SAFE OPERATION Kickback Safety Precautions for Chain Saw Users WARNING! KICKBACK 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. Rotational kickback Tip contact in some cases may cause a lightning fast reverse REACTION, Kicking the guide bar up and back towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.
CORRECT USE OF CHAIN BRAKE CHAIN BRAKE OPERATION Chain brake function When the lever is pushed forward, chain brake instantly stops the chain. • Set the lever in the unlocked position before starting to cut. • If the brake is tripped by kickback reaction, the chain will stop immediately. Release the throttle to avoid possible damage to the engine or clutch. • Do not attempt to operate the engine with the brake locked.
AUTOMATIC CHAIN BRAKE End of the guide bar may be placed at the height of about 35 cm (14 in.). Kickback produced from the tip of the guide bar will trip the automatic chain brake. To make sure that the automatic chain brake operates properly, follow these steps: 1. Stop the engine. 2. Hold the saw with the guide bar approximately 35 cm (14 in.) above a wooden surface. Right hand should hold the rear handle, and left hand should hold the front handle. 3.
12. 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. 17. All chain saw service, other than items listed in the Instruction manual maintenance instructions, should be performed by competent service personnel.
OPERATOR SAFETY VIBRATION AND COLD • It is believed that a condition called Raynaud’s Phenomenon, which affects the fingers of certain individuals, may be brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning followed by loss of color and numbness in the fingers.The following precautions are strongly recommended because the minimum exposure which might trigger the ailment is unknown.

FELLING THE TREE 3 m (10 feet) Direction of fall warning Retreat A falling tree can seriously damage anything it may hit - a car, a house, a fence, a power line, or another tree. There are ways to make a tree fall where you want it, so first decide where that is! Not this way Before cutting, clear the area around the tree.You will need good footing while working and you should be able to work the saw without hitting any obstacles. Next, select a path of retreat.
Limbing Limbing a fallen tree is much the same as bucking. Never stand on the tree that you are limbing. When limbing, caution is the word. Be careful of the tip touching other limbs. Always use both hands. Don’t cut with the saw overhead or aligned vertically with your body. If the saw should kickback, you may not have enough control to prevent possible injury. Bucking Bucking is the sawing of a log or fallen tree into smaller pieces. There are a few basic rules which apply to all bucking operations.

• Place the depth gauge tool firmly on guide bar so that depth gauge protrudes. Then file top of depth gauge with the flat file until flat with top of the depth gauge tool. 1/5 One fifth of file diameter remains above cutter edge • Be sure to round off the front edge of the depth gauge.
