Fig 8.Feeder reel speed settings.
D The speed is suitable when the wood does not push
against the grinding wheel or the feeder reel spikes
do not slow down the feeding of wood.
D Make sure that you are using clean oil in the
hydraulic system. Dirt in the oil will damage valves
and hydraulic motors.
7.5.EMTYING THE CHIPPER AFTER USE
D Before stopping the chipper, chip about ∅ 80---100
mm wood. Let the blades cut a few centimetres, after
which reverse the feed direction to clean the blades.
Leave the tree into the feeder to remind you that the
chipper has been emptied. This way you will avoid a
possible jam when you turn on the chipper next time.
When you stop the chipper, wait for all
movement to stop. The grinding wheel
will continue to revolve like a flywheel
once the power outlet has been switched

off.
8.CHANGING THE HYDRAULIC UNIT
FOR USE WITH CONSTANT
PRESSURE PUMPS
The chipper valve is built for fixed displacement
pumps. If your tractor has a constant pressure
pump, the hydraulic feeder unit should be modified
as follows:
D Insert a plug in the directional control valve -- see Fig 9.
D Remove the hose and T--nipple and insert a plug in the
end of the flow regulator valve -- see Fig 10.
D Connect the tank hose directly to the directional control
valve -- see Fig 11.

D Instructions for connecting the hydraulics when using
the optional hydraulic unit can be found in hydraulic
units mounting instructions.
9.MAINTENANCE
D The feed roller bearings are sealed and do not
require periodic maintenance.
D Lubricate the roller bracket shaft slide bearings after
every 20 operating hours.
D Check and tighten loose bolts at regular intervals.
D Check the condition of the hydraulic hoses and
regularly inspect the connections for leaks.
D Be sure to use only clean oil in the hydraulic system.
The presence of impurities in oil damages the valves
and hydraulic motors.
