Filing Cutter Depth Gauges
The cutter depth gauge clearance is reduced as cutters are sharpened. After every second or third sharpening, reset cutter depth gauges.
1.Place depth gauge tool (.025") firmly across top of two cutters. Make sure depth gauge enters slot in depth gauge tool (see Figure 22).
2.Use medium flat file. File depth gauge level with depth gauge tool.
3.Remove depth gauge tool. With flat file, round off front corner of cutter depth gauge (see Figure 23).
After several hand filings, have authorized service center or sharpening service machine sharpen chain. This will insure even filing.

SHARPENING SAW CHAIN
(Fast Sharp Model)
WARNING: Unplug chain saw from power source before servic- ing. Severe injury or death could occur from electrical shock or body contact with moving chain.
WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain.
WARNING: Do not hand- sharpen this Fast Sharp chain.
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.
Follow the steps below to sharpen Fast Sharp chain. The automatic chain sharpener sharpens cutter, lowers cutter depth gauge, and adjusts guard drive link.
1.Adjust saw chain for proper tension (see Saw Chain Tension Adjustment, page 7).
2.Clean out excess sawdust and wood chips from drive sprocket area.
3.Turn sharpener knob counterclockwise until clicking stops (see Figure 24).
4.Turn sharpener knob clockwise until you hear five distinct clicks.

5.Place saw on clean, flat surface.
6.Connect saw to power supply.
7.Hold saw, with both hands in normal cutting position.
8.Press in switch lockout with right thumb and squeeze trigger.
9.Gently push on sharpener knob. Saw must be running for chain to sharpen.
Note: Sparks appearing shows sharp- ener is working (see Figure 25). If no sparks appear, continue to adjust sharp- ener one click at a time. After each click, press sharpener knob until light flow of sparks appears.
After several sharpenings, you must turn sharpener knob more to bring stone into position.

REPLACING SAW CHAIN
Replace chain when cutters are too worn to sharpen or when chain breaks. Only use replacement chain noted in this manual. Always include new drive sprocket when replacing chain. This will maintain proper driving of chain. Note: For proper chain and drive sprocket, see Replacement Parts and Accessories, on back cover.
