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.
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 fat 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, page 19, for replacement information. See Parts List, page 42, for correct bar.

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
