PROPER GRIP ON HANDLES

See Figures 20 and 21.

Refer to “Specific Safety Rules – Safety Apparel” earlier in this manual for appropriate safety equipment.

Wear non-slip gloves for maximum grip and protection.

Hold the saw firmly with both hands. Always keep your LEFT HAND on the front handle and your RIGHT HAND on the rear handle so that your body is to the left of the chain line.

WARNING:

CHAIN LINE

WARNING:

Never use a left-handed (cross-handed) grip or any stance that would place your body or arm across the chain line.

Maintain a proper grip on the saw whenever the engine is running.The fingers should encircle the handle and the thumb be wrapped under the handlebar.This grip is least likely to be broken (by a kick-back or other sudden reaction of the saw). Any grip in which the thumb and fingers are on the same side of the handle is dangerous because a slight kick of the saw can cause loss of control.
