OPERATION

BASIC OPERATING/CUTTING PROCEDURES

Practise 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. Forcing the cut could result in damage to the bar, chain or engine.

6.Release the throttle trigger as soon as the cut is completed 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.

7.Do not put pressure on the saw at the end of the cut.

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 chainsaw who has not read this operator’s manual or received adequate instructions for the safe and proper use of this chainsaw.

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 4.5 m (15 ft) between workers.

ADJUSTING THE CARBURETTOR

Before adjusting the carburettor, clean the air filter and the starter cover vents. Allow the engine to warm up before carburettor adjustment. Refer to “Maintenance” later in this manual.

Fig. 23

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 kick-back forces.

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

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