Use and Care Manual

Prepare two pieces of cardboard, one is 1mm thick, other is 3mm
thick. They are usually good gap gauges for resetting the wear
plate.
1. Remove the feed hopper. (See Figure 13)
2. Loosen the bolts that x the wear plate.
3. Use a stick to rotate the cutting disk to move the inside knife
next to the wear plate. Put the 1mm gap gauge in the clearance
between the inside blade and the wear plate. Slide it at the
position of closest to the rotor shaft. Keep the clearance 1mm.
(See Figure 19)
4. Rotate the cutting disk to move the outside knife next to the
wear plate. Put the 3mm gap gauge in the clearance between
the outside blade and the wear plate. Slide it at the position
of farthest to the rotor shaft. Keep the clearance 3mm. (See
Figure 20)
If the wear plate is not set correctly, excessive vibration will
occur when chipping and the knife will seem to be dull. If there is
not enough clearance, the knife edges may touch the wear plate
through deection when cutting heavy branches and damage the
sharp edge. Too much clearance will allow small twigs and brous
materials to be dragged through without being cut.

After the maintenance or adjustment have been made,
rotate the cutting disk with a stick and watch and
listen carefully for unusual noises, clicking or vibration.
If you detect any of these, inspect the machine for
damage or loose parts and repair, replace, or tighten
before starting the machine.

5. Fasten the bolts of wear plate.
NOTE: The wear plate can be adjusted through the mounting slots.
Loosen the bolts that x the wear plate and move the wear plate in
the long holes, then x the bolts when reach the right clearance.

V-BELT CHECK
To ensure the optimum power for the transmission from the
engine to the rotor shaft, check the V-Belts are in good condition
and are operation under the proper tension.
1. Turn off the engine. The engine must be cool.
2. Pull up the belt tension lever to tighten the belts.
