ADJUSTMENT: GUIDE RAIL
The straightness of the guide bar can vary
between different chainsaws.
It should only be necessary to adjust a guide
bar once, provided that it is not bent during
sawing.
If you notice that you have to readjust
the guide bar in the same direction when
turning it over, it may be that the guide
bar mount is not straight. This can be
compensated for by placing one or more
shims between the slide rails and the
carriage bottom plate.
You can use thin pieces of aluminium plate
from a soft drink can.
Tighten the lower bolt joints where the
guide rail struts are tted to the strut plates
in the long legs.
Look along the guide rail and press it
straight at the same time as you tighten the
upper bolt joints.
Check the straightness of the guide rail. Look along the guide rail from one of its top corners, and you can
easily see if it is not straight. You can also stretch a string along the guide rail. Place a coin under the string
on both ends of the guide rail, so you get a gap between the string and the guide rail.
