CLEANING AND MAINTENANCE
NOTICE: Below are instructions for servicing your chain saw. Any servicing not mentioned below should be done by an authorized service center.
CLEANING SAW BODY
WARNING: Remove battery from chain saw before servicing. Severe injury or death could oc- cur from body contact with mov- ing chain.
WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain.
WARNING: When cleaning saw body,
•do not submerge saw in any liquids
•do not use products that contain ammonia, chlorine, or abrasives
•do not use chlorinated cleaning solvents, carbon tetrachloride, kerosene, or gasoline
Keep saw body clean. Use a soft cloth damp- ened with a mild soap and water mixture. Wipe saw body to clean.
CARE OF GUIDE BAR
Uneven bar wear causes most guide bar prob- lems. Incorrect sharpening of chain cutter and depth gauge settings often cause this. When bar wears unevenly, it widens guide bar groove (see Figure 30). This causes chain clatter and rivet popping. Saw will not cut straight. Replace guide bar if this occurs.
Inspect guide bar before sharpening chain. A worn or damaged guide bar is unsafe. A worn or damaged guide bar will damage chain. It will also make cutting harder.

Normal Guide Bar Maintenance
1.Remove guide bar from chain saw.
2.Remove sawdust from guide bar groove periodically. Use putty knife or wire (see Figure 31).
3.Clean oil slots after each day of use.
4.Remove burrs from sides of guide bar. Use flat file to make side edges square.
Replace guide bar when
•bar is bent or cracked
•inside groove of bar is badly worn
Note: When replacing guide bar, see Replacement Parts and Accessories for replacement information. See Parts Lis for correct bar.

SHARPENING SAW CHAIN
WARNING: Remove battery from chain saw before servicing. Severe injury or death could oc- cur from body contact with mov- ing chain.
WARNING: Cutting edges on chain are sharp. Use protective gloves when handling 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.
Items Needed to Sharpen Chain
Purchase these items from your local dealer, hardware store, or chain saw sup- plies outlet.
•5/32" round file
•Depth gauge tool
•File guide
•Vise
•Medium sized flat file
Sharpening Cutters
Use file guide for 30° filing.
1.Adjust chain for proper tension (see Saw Chain Tension, page 11).
2.Clamp guide bar in vise to hold saw steady. Note: Do not clamp chain.
3.Press 5/32" round file (attached to file guide) into groove between top plate and depth gauge on chain. File guide should rest on both top plate and depth gauge (see Figure 32). Note: File at midpoint of guide bar.

4.Hold file guide level. Make sure 30° mark on file guide is parallel to cen- ter of guide bar (see Figure 33). This will insure that you file cutters at 30° angle.
5.File from inside towards outside of cutter until sharp. Only file in this one direction (see Figure 33). Note: Two or three strokes with file should sharpen cutter.
6.After each cutter is sharpened, 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.
