2. GUIDE BAR MAINTENANCE
• Conditions which can require guide bar
maintenance:
— saw cuts to one side
— saw has to be forced through a cut
—inadequate supply of oil to bar and
chain.
• Check the condition of the guide bar each
time the chain is sharpened. A worn guide
bar wil) damage the chain and make cut­
ting more difficult.
• Replace the guide bar when:
— the inside groove of the guide bar rails is
worn.
— the guide bar is bent or cracked.
Figure 34
• Use only the Reduced-Kickback Guide Bar
specified for your saw in “Specifications” for
replacement.
a. Remove the guide bar to service.
b. Clean oil holes at least once for each five
hours of operation.
c. Remove sawdust from the guide bar
groove periodically with a putty knife or a
wire. Figure 36.
d. Remove burrs by filing the side edges of
the guide bar grooves square with a flat file.
Figure 37.
e. Restore square edges to an uneven rail
top by filing with a flat file. Figure 37.
