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 Fig. U).
3. Make sure to clean oil passages thoroughly
Conditions which require 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, with unit disconnected from
power source, 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.
File Rail Edges
and Sides
Square
Worn 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.
Replacing bar & Chain
Replace chain when cutters are too worn
to sharpen or when chain stops. Only use
replacement chain noted in this manual.
Always include new drive sprocket when
replacing chain. This will maintain proper
driving of chain.
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 catch into the new
bar by tightening the screw clockwise. The
catch protrude (b) must be fitted into the bar
hole (See Fig. S).

ShaRPENiNg 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.
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.
