Working with the shredder
1. Safety and technical remarks
1.1. The user should be 18 years old or more.
1.2. The machine should be positioned on a horizontal. Firm surface.
1.3. User must wear safety gloves (not provided with this unit), ear-protection and safety goggles.
(fig.4)
1.4. When working in a confined space, always make sure there is sufficient ventilation and
lighting, in order to reduce the risk of suffocation and injury.
1.5. Only one person at a time should operate the machine.
1.6. Pieces jamming the input tube can only be removed safely when the engine is stopped and
blocked. If necessary, unbolt and tip the input and output tubes to facilitate access to the
rotor. Use a wooden pole to remove pieces stuck in the rotor. Never use your
hands.(fig.6-8)
1.7. Never leave the machine running unattended.
1.8. Changing the blades of the rotor or the counter blade and checking blade bolts should only
be done when the engine and rotor are stopped, the spark plug cap is removed and the
rotor is blocked.
1.9. After one hour of use always check that all bolts and nuts are still tightened properly. If not,
tighten them again or bring the machine back to your dealer/service-point.
1.10. Use only original parts for maintaining your shredder, otherwise the warranty will be void.
1.11. The shredder can only be repaired by a skilled dealer/service-point.
1.12. The shredder exceeds 108 dBA during operation. Therefore all users and onlookers must
wear ear-protection.
1.13. Before use, make secure that the bolts on the fixed blade are firmly fixed. Check after one
hour that the bolts still are firmly fixed (just first time).

2. Before operating the machine
Make sure the machine stands firmly on the ground and does not tilt in any way. The danger
zone on the output of the machine must be respected, in order to avoid serious injury by chips
thrown out of the output tube. chips can be thrown a distance of 12 meters, so onlooker must
remain behind the direction of throw or at least 12 meters away from the output tube.
Before using the machine for the first time, check the maximum engine speed by screwing in/out
the screw which controls the position of the throttle lever so that it is positioned as in the
diagram.
After the first hour’s use check that the bolts of the blades and counter blade are firmly fixed and
that the gap between blades and counter blade is 0.5mm (half a millimeter ). Adjust in the slots if
necessary and fix the bolts.
3. Starting and operating the machine
Start the engine at half throttle and let it warm up for about 3 minutes. (for proper use of the
engine on should also read the engine manual). Then put the engine on full throttle.(fig.9,10)
Put the branches in the input tube and when you feel they are pulled in by the rotating blades, let
the branch go. Do not hang on to the branch, the branch will be pulled in by the machine by itself.
Warning!
In case of emergency or any doubt, immediately activate the safety switch (red knob) to be found
by the engine.(fig.11)
Before starting the engine check that the bolts holding the input and output tubes are fully
tightened.(fig.12,13)

4. Transport
Before moving the machine, stop the engine!
Maintenance and checks
All technical check-ups and maintenance should be done with the engine shut off and the spark
plug cap removed from the spark plug.
While cleaning the shredder, never spray the bearing with a high pressure washer! It could cause
water to enter the bearings which will cause damage to the machine; (this is not covered by
warranty). The two grease nipples on the rotor require lubricating once a year or every 500
hours.
Before putting the shredder into storage grease or oil the bearings, blades and rotor to protect
against corrosion.
1. Points to be checked
2. Cleaning the machine
For engine maintenance refer to the engine manufacturers engine manual.
Note that the first engine oil change is after 5 hours use.

Problem & Solutions
Problem
Cause
Solution
The shredder does not
perform properly: the
wood is not pulled in by
the machine itself. The
chips do not have the
same size.
-the blades are worn too
much
-the diameter of the
branches inserted into the
machine is too large
-there is too big a gap
between the fixed blade
and the counter blade:
correct gap is 0.5 mm (half
a millimeter)
-change or sharpen the blades and
counter-blade. Note that the blades are
sharpened on both edges so they can be
reversed.
-shut the engine off and remove the branch
that is too thick
-adjust the gap between the blade and the
counter-blade in the slots
The engine does not
start/ the engine shuts
off by itself
-electrical problem whit
the engine
-no fuel
-no or not enough oil in the
engine (the oil should be
level with the threads of
the fillr hole.)
Check that
-the input tube is correctly fitted and the
bolts are tight
-put the start-switch of the engine “on”
-de-activate the emergency switch (turn the
knob)
-check oil and fuel levels
-contact your dealer
Important : screw back the blade bolts.
The rotor jams
The engine will not start/
turn because the rotor is
jammed.
-the diameter of the
branch is too big
-there are unacceptable
materials such as stones
or metal in the input tube
-a length of branch
remains in the rotor
remains in the rotor after
the engine was last
stopped.
-shut off the engine, remove the spark plug
cap and turn the rotor counter-clock-wise.
Use a wooden stick to turn the rotor and to
remove the material from the rotor and
input tube.
If necessary, remove the cap of the bearing
housing and rotate the rotor axle with a
spanner.
If necessary, remove the input or output tube
to facilitate access to the rotor.
Check the sharpeness of the blades and
counter blade and replace them if
necessary.
Important: screw back the blade bolts.
