MAINTENANCE
GEAR
There is a grease nipple and a plug for injecting lubricant into
the gear housing. Use a grease gun to fill with grease. This
should be done after every 25 working hours. (see Fig. 23)
CAUTION!
The gear housing must not be filled completely
with grease. The grease expands as the machine heats up
during operation. If the gear housing was completely filled with
grease it could damage the seals and lead to leakage of grease.
The grease in the bevel gear does not normally need to be
changed except if repairs are carried out.
NOTE: The gear housing gets hot when the machine has been in
use. To avoid burning yourself do not touch the gear housing.
CUTTING BLADE
Clean any resin and plant residue from the blades using
cleaning agent before and after using the machine.
Lubricate the blade bars with rust preventive oil before long
periods of storage. (see Fig. 24)
To ensure good cutting results it is important that the contact
pressure between the blades is correct. The contact pressure
is adjusted by turning the screws on the underside of the bar
clockwise as far as they will go. Lock the screws using the
locking nut on the top of the bar. (see Fig. 25)
Check that the screws are loose enough to allow the washers
under the screw heads to slide sideways.
When the blades are correctly adjusted the play between the
blades should be 0,2–0,4mm, measured at the screws.
The edges of the blades are too hard to be filed. Dull blades
should be sharpened using a grinder.
Replace the blades if they are bent or damaged.
HAND GUARD
The hand guard prevents hands from coming into contact with
the moving blades, for example, if the operator loses grip on the
front handle. (see Fig. 26)
Check that the hand guard is fitted correctly.
Check that the hand guard is undamaged
