1.Fill the oil tank every time engine is fueled. Chain saw should use approximately one tank of oil per tank of fuel.

2.The automatic oil pump is a positive displacement pump operated through gears driven off the clutch drum assembly. The pump will not oil at idle speeds.

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.

WARNING: 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 Fig. 41, 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. Left-handers should follow these instructions too.

2.Maintain a proper grip (B, Fig. 42) 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 (C), is dangerous because a slight kick of the saw can cause loss of control.

WARNING:

Proper Cutting Stance (Fig. 43)

-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 pres- sure. 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.
