Guide Bar
1. The guide bar groove should be cleaned every time
the saw chain is removed or at regular intervals.
This can be done with any instrument small enough
to fit in the groove. Run the instrument along the
groove to remove all the residue.
2. The oil passage in the base of the guide bar should
be cleaned every time the saw chain is removed or
at regular intervals to ensure proper lubrication to
the chain and bar. This can be done with any
instrument small enough to insert into the passage.
Remove all the residue.
3. The guide bar should be turned from top to bottom
every time the saw chain is removed or at regular
intervals to help ensure even guide bar rail and
groove wear.
4. The guide bar rails should be checked for wear at
regular intervals.
A. Place a straight edge against the side of the
guide bar and one cutter.
B. If the saw chain is straight and there is clearance
between the guide bar and straight edge, the
guide bar rails are good. See Figure 15.
C. If the saw chain leans and there is no clearance
between the guide bar and straight edge, the
guide bar rails are worn. See Figure 16. Replace
the bar.
