SHARPENING YOUR SAW

ing. Severe injury or death could
occur from electrical shock or
body contact with moving chain.

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.
