SHARPENING YOUR HOMELITE¨ DUAL RAKER SAW CHAIN

WARNING: Unplug chain saw from power source before ser- vicing. Severe injury or death could occur from electrical shock or body contact with moving chain.

Sharpening Cutters

Use file holder for 30° filing.

1.Adjust chain for proper tension (see Saw Chain Tension Adjustment, page 7).

2.Clamp guide bar in vise to hold saw steady. Note: Do not clamp chain.

3.Press 5/32" round file (attached to file holder) into groove between top plate and depth gauges on chain. File holder should rest on top plate of cutter tooth (see Figures 19 and 20). Note: File at midpoint of guide bar.

4.Hold file holder level. Make sure 30° mark on file holder is parallel to center

of guide bar (see Figure 19). This will insure that you file cutters at 30° angle.

5.File from inside towards outside of cut- ter until sharp. Only file in this one di- rection (see Figure 19). Note: Two or three strokes with file should sharpen cutter.

6.After sharpening each cutter, move chain forward to sharpen next cutter. File all cutters on one side of chain.

7.Move to other side of chain and repeat process.

WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain.

Kickback-suppressing type 35-MD50 semi- chisel tooth, 3/8" pitch, Dual Raker saw chain has two rakers (depth gauges) instead of just one gauge preceding each tooth. When chain contact is made within the kickback zone of a guide bar nose, the two rakers provide sufficient support to prevent the cutters from pulling themselves deeply into the wood. Thus the tendency toward a violent kickback reaction is suppressed or reduced.

Keep chain sharp. Your saw will cut faster and more safely. A dull chain will cause undue sprocket, guide bar, chain and motor wear. If you must force chain into wood and cutting creates only sawdust with few large chips, chain is dull.
