OPERATION

PROPER CUTTING STANCE

See Figure 19.

n Balance your weight with both feet on solid ground.

nKeep left arm with elbow locked in a “straight arm” posi- tion to withstand any kickback force.

nKeep your body to the left of the chain line.

nKeep your thumb on underside of handlebar.

WORK AREA PRECAUTIONS

See Figure 20.

nCut only wood or materials made from wood; no sheet metal, no plastics, no masonry, no non-wood building materials.

n Never allow children to operate the saw. Allow no person to use this chain saw who has not read this operator’s manual or received adequate instructions for the safe and proper use of this chain saw.

n Keep everyone – helpers, bystanders, children, and ani- mals, a SAFE DISTANCE from the cutting area. During felling operations, the safe distance should be a least twice the height of the largest trees in the felling area. During bucking operations, keep a minimum distance of 15 feet between workers.

n Always cut with both feet on solid ground to prevent being pulled off balance.

n Do not cut above chest height as a saw held higher is difficult to control against kickback forces.

n Do not fell trees near electrical wires or buildings. Leave this operation for professionals.

n Cut only when visibility and light are adequate for you to see clearly.

BASIC OPERATING/CUTTING PROCEDURES

Practice cutting a few small logs using the following technique to get the “feel” of using the saw before you begin a major sawing operation.

nTake the proper stance in front of the wood with the saw idling.

nAccelerate the engine to full throttle just before entering the cut by squeezing the throttle trigger.

nBegin cutting with the saw against the log.

nKeep the engine at full throttle the entire time you are cutting.

nAllow the chain to cut for you; exert only light downward pressure. Forcing the cut could result in damage to the bar, chain, or engine.

nRelease the throttle trigger as soon as the cut is com- pleted allowing the engine to idle. Running the saw at full throttle without a cutting load can result in unnecessary wear to the chain, bar, and engine.

nDo not put pressure on the saw at the end of the cut.
