CLEANING AND MAINTENANCE

NOTICE

Below are instructions for servicing your chain saw. Any servicing not mentioned below should be done by an authorized service person.

CLEANING SAW BODY

!WARNING

Unplug chain saw from power source before servicing. 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

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 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 18). 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.

SHARPENING YOUR SAW CHAIN

!WARNING

Unplug chain saw from power source before servicing. 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.

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.

Purchase these items from your local dealer, hardware store, or

chain saw supplies outlet.
