CLEANING AND MAINTENANCE

Cleaning Saw Body

WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain.
body,WARNING: When cleaning saw
•do not submerge saw in any liq- uids
•do not use products that contain ammonia, chlorine, or abrasives
•do not use chlorinated cleaning solvents, carbon tetrachloride, kero- sene, or gasoline
Keep saw body clean. Use a soft cloth dampened with a mild soap and water mixture. Wipe saw body to clean.
Care of Guide Bar
Uneven bar wear causes most guide bar problems. Incorrect sharpening of chain cutter and depth gauge settings often cause this. When bar wears unevenly, it widens guide bar groove (see Figure 21). 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.
