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 17). This
causes chain clatter and rivet popping. Saw will not
cut straight. Replace
guide bar if this occurs.
Inspect guide bgu be`tore sharpening chain. A worn or
demaged guide bar is unsa`t_. A worn or damaged guide
bar will damage chain. It will also make cutting harder.
Normal Guide Bar Maintenance
1. Remove guide bar from chain saw.
2.
Remove sawdust from guide bar groove periodi-
cally. Use putty knife or wire (see Figure 18).
3.
Clean oil slots after each day of use.
4.
Remove burrs from sides of guide bar. Use flat
file to make side edges square.
Replace
guide bar when
• bar is bent or crocked
• inside groove of bar is badly worn
