IMPORTANT:
Be sure that the depth gauge is not cut
back too far, as doing so will result in
a faster deterioration of the cutter.

Guide bar care

1. When work using the pruner is finished for the
0.64mm
day, remove the guide bar and saw chain from the
pruner.

2. Remove any wood chips or other particles
attached to the groove of the guide bar or in the oil
hole. Be particularly certain that no particles are
clogging the oil hole.

oil discharge hole and around the sprocket on the
main unit of the pruner.

IMPORTANT:
• When installing the guide bar,
occasionally switch it to the top and
bottom to prevent uneven wear and to
extend the life of the guide bar.
• If the oil discharge hole becomes
clogged by wood chips or other particles
the pruner could seize up.

2. If the sprocket is worn by 0.3 mm or more, as
shown in the diagram below, replace the sprocket.
Continuing to use the pruner with the sprocket in
55°
such a condition will shorten the life of the saw
chain.
