CARE OF GUIDE BAR
Uneven bar wear causes most guide bar problems.
Incorrect sharpening of chain cutter and depth gauge
settings often cause this. When bar wears unevenly,
it widens guide bar groove (see Figure 19). This
causes chain clatter and rivet popping. Saw will not
cut straight. Replace guide bar if this occurs.
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.
CLEANING SAW BODY
WARNING: When cleaning saw
body,
• do not submerge saw in any liquids
• do not use products that contain am-
monia, chlorine, or abrasives
• do not use chlorinated cleaning sol-
vents, carbon tetrachloride, kerosene,
or gasoline
Keep saw body clean. Use a soft cloth dampened with a
mild soap and water mixture. Wipe saw body to clean.
