OPERATING INSTRUCTIONS
C190-0176 01.03.2019 Rev: 2.0
BLOCKAGES
In the event of heavy blockages the rotor housing access hatch can be removed (see parts locator on page 3).
Allow machine time to clear excess chips still remaining in rotor housing before you continue feeding brushwood. Feed in
a small piece of wood while watching to make sure that it comes out of the discharge. If this does not clear it, repeat the
process and carefully inspect the discharge tube to find any obstruction.
NOTE
Continuing to feed the chipper with brushwood once it has become blocked will cause the chipper to compact the chips
in the rotor housing and it will be difficult and time consuming to clear.
AVOID THIS SITUATION - WATCH THE DISCHARGE TUBE AT ALL TIMES.
WARNING
DO NOT REACH INTO THE
ROTOR HOUSING WITH
UNPROTECTED HANDS.
THERE ARE SHARP
BLADES AND ANY SMALL
MOVEMENT OF THE
ROTOR MAY CAUSE
SERIOUS INJURY.
STARTING TO CHIP
CHIPPING
Chipping must be performed at maximum engine speed. Wood up to the recommended diameter can be fed into the
feed funnel. Put the butt end in first and engage it with the feed rollers. The hydraulic feed rollers will pull the branch into
the machine quite quickly. Large diameter material will have its feed rate automatically controlled by the no stress unit.
Sometimes a piece of wood that is a particularly awkward shape is too strong for the feed rollers to break. This will cause
the top roller to either bounce up and down on the wood, or both rollers to stall. If this occurs, press the
blue reverse
feed control until the material has been released. Pull the material out of the feed funnel and trim it so the chipper can
handle it.
Both feed rollers should always turn at the same speed. If one or both rollers stop or suddenly slow down it may be that
a piece of wood has become stuck behind one of the rollers. If this occurs, press the
blue reverse feed control and hold
for 2 seconds - then repress green forward feed control. This should enable the rollers to free the offending piece of
material and continue rotating at the correct speed. If the rollers continue to stall in the 'forward feed' or 'reverse feed',
turn the engine off, remove the ignition key and investigate.
WARNING
DO NOT USE OR
ATTEMPT TO START THE
CHIPPER WITHOUT THE
PROTECTIVE GUARDING
AND DISCHARGE UNIT
SECURELY IN PLACE.
FAILURE TO DO SO MAY
RESULT IN PERSONAL
INJURY OR LOSS OF LIFE.
Check that the machine is level and running smoothly. •
Release the catches on the feed tray and lower into the working •
position. Pull to release the red stop button.
Perform the “before using the chipper” checks (see page 11). This
•
will take you through the starting procedure and get the machine
up to the point of use.
Press the
green forward feed control. The rollers will begin to turn •
in the forward feed direction.
Immediately check the function of the
red safety bar and also the •
blue reverse feed controls on both sides of the feed tray.
Stand to one side of the feed tray. •
Repress the green forward feed control. •
Commence feeding material. •
ROTATION

DISCHARGE CONTROLS
Controlling the discharge is an essential part of safe working.
BUCKET ANGLE
Adjust the bucket to the desired angle using the
handle provided.

Always be aware that what you are putting into the chipper must
come out. If the chips stop coming out of the discharge tube but the
chipper is taking material in - STOP IMMEDIATELY. Continuing to feed
material into a blocked machine may cause damage and will make it
difficult to clear.
If the chipper becomes blocked, proceed as follows:
Stop the engine and remove the ignition keys. •
Remove the discharge tube. Check that it is clear. •
Wearing gloves, reach into the rotor housing and scoop out the •
majority of the debris causing the blockage.
Replace the discharge tube. •
Restart the engine and increase to full speed. •
