OPERATION

BASIC OPERATING/CUTTING PROCEDURES

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

6.Release 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 unneces- sary wear to the chain, bar, and engine.

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

WORK AREA PRECAUTIONS

See Figure 19.

￿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.

Fig. 19

￿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.

ADJUSTING THE CARBURETOR

See Figures 20 and 21.

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

STARTER COVER

VENTS

The carburetor is factory set and should not require adjusting. The carburetor will permit only limited adjust- ment of the “L” (Low Jet) and “H” (High Jet) needles. Any adjustment should be done by a Homelite Service Center.

Under no circumstances should the “L” (Low Jet) and “H” (High Jet) needles be forced outside the range of adjust- ment.

CAUTION:

Serious damage can occur to the engine if improper adjustments are made to the “L” and “H” needles.

Do not force the “L” and “H” needles outside the adjustment range!
