Maintenance
3. TO CLEAN THE BAR RAILS
1) Remove chain cover and bar and chain. (see section ASSEMBLY)
2) Using a wire brush, screwdriver or similar tool, clear the residue from the inner
groove of the bar. (See F)
3) Make sure to clean oil passages thoroughly.
Conditions which require chain and guide bar maintenance:
Saw cuts to one side or at an angle.
Saw has to be forced through the cut.
Inadequate supply of oil to the bar and chain.
Check the condition of the guide bar each time the chain is sharpened. A worn guide
bar will damage the chain and make cutting difficult.
After each use, remove the battery pack, clean all sawdust from the guide bar and
sprocket hole.
When rail top is uneven, use a flat file to restore square edges and sides.

Worn Groove
Correct Groove
Replace the guide bar when the groove is worn, the guide bar is bent or cracked, or
when excess heating or burring of the rails occurs. If replacement is necessary, use
only the guide bar specified for your saw in the repair parts list or on the decal located
on the chain saw.
4. REPLACING BAR & CHAIN
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 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.
Fit the bar tensioning plate tab into the new bar by tightening the screw clockwise.
The tab protrusion (a) must be fitted into the bar hole. (See G)
