Replacing/Changing Chain
And Guide Bar Fig. 23
Replace chain when cutters are too worn to sharpen or
when chain stops.
Only use replacement chain noted in this manual.
Inspect Guide Bar before replacing chain.
A worn or damaged Guide Bar is unsafe and will damage
chain. It will also make cutting harder.
Fit the chain and guide bar as described in
"Assembly and Tensioning Chain", (See pages 16 and 17). The circular groove of the
guide bar will wear particularly on the lower edge with time. When replacing the chain turn
the chain bar 180 ° to allow even wear, thus extending chain bar life.
Check Drive Sprocket. If it is worn out or damaged due to strain,
have it exchanged by an authorized service dealer.
If The Chain Bar Is Worn Out Or Damaged, take the chain tensioning catch off the bar by
loosing the screw counter-clockwise. Then fit the tensioning catch into the new bar by tightening
the screw clockwise. The catch protrude (1) must be fitted into the bar hole. (See Fig. 23)
SHARPENING SAW CHAIN
A WARNING:
Unplug chain saw from power source before servicing. Severe injury
or death could occur from electrical shock or body contact with moving chain. 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.
