Inspection of sprocket
1. Inspect the sprocket to ensure that the screw is not loose
or that it is not worn out.
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 such a
condition will shorten the life of the saw chain.
Gearcase
1. Remove the gear case from the shaft assembly.
2. Remove the grease plug and prepare some lithiumtype
grease.
3. Inject enough grease (about 10g) so that some of it spills
out through the spline hole, to which the drive shaft is
inserted.
Guide bar care
1. When work using the pruner is finished for the day, re
-
move 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.
3. Remove wood chips and other particles around the 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.
