OPERATION
Preparation for Cutting
Proper Grip on Handles
Refer to Safety Section for appropriate Safety Equipment.
1. Wear non-slip gloves for maximum grip and protection.
2. Maintain a proper grip (A) on the saw whenever the engine is
running. The fingers should encircle the handlebar and the
thumb is wrapped under the handlebar. This grip is least likely
to be broken (by a kickback or other sudden reaction of the
saw). Any grip in which the thumb and fingers are on the same
side of the handle (B), is dangerous because a slight kick of the
saw can cause loss of control.

3. Hold the saw firmly with both hands. Always keep your LEFT
HAND on the front handlebar and your RIGHT HAND on the
rear (throttle) handle as shown in Illustration (C), so that your
body is to the left of the chain line. Never use a cross-handed
grip, or any stance which would place your body or arm across
the chain line.
Proper Cutting Stance
Weight should be balanced on both feet - feet on solid ground.
Keep arm with elbow locked in a "straight arm" position (D) to
withstand any kickback force.
Your body should always be to the left of the chain line (E).
Thumb on underside of handlebar (F).

Basic Cutting Procedure
Practice cutting a few small logs using the following technique
to get the "feel" of using your saw before you begin a major
sawing operation.
1. Take the proper stance in front of the wood with the saw idling.
2. Accelerate the engine to full throttle just before entering the cut
by squeezing the throttle trigger.
3. Begin cutting with the saw against the log.
4. Keep the engine at full throttle the entire time you are cutting.
5. Allow the chain to cut for you; exert only light downward
pressure. If you force the cut, damage to the bar, chain, or
engine can result.
6. Release the throttle trigger as soon as the cut is completed,
allowing the engine to idle. If you run the saw at full throttle
without a cutting load, unnecessary wear or damage can
occur to the chain, bar, and engine.
7. Do not put pressure on the saw at the end of the cut.
Always cut with both feet on solid ground to prevent being
pulled off balance.
Do not cut above chest height, as a saw held higher is difficult
to control against kickback forces.
Do not fell trees near electrical wires or buildings. Leave this
operation for professionals.
Cut only when visibility and light are adequate for you to see
clearly.
Work Area Precautions
Cut only wood or materials made from wood; no sheet metal,
no plastics, no masonry, no non-wood building materials.
Never allow children to operate your 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.
Keep everyone - helpers, bystanders, children, and animals 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 (4.5m) between workers.
