PROBLEMS, CAUSES & SOLUTIONS
Problem Cause
The shredder does not - The blades are worn too much
perform properly: the
wood is not pulled in - The diameter of the branches
by the rotor itself inserted into the machine is too large
The chips do not have - There is too big a gap between the
the same size fixed blade and the counter blade:
correct gap is 0.5 mm (half a mil-
limetre)
The engine does not - Electrical problem with the engine
start/ the engine shuts
off by itself -No fuel
- No or not enough oil in the engine
(the oil should be level with the
threads of the filler hole.)
The machine jams - the diameter of the branch is too big
during use - there are unacceptable materials
The engine will not such as stones or metal in the input
start/turn because the tube
rotor is jammed
The machine does not Too much wet material (leaves,
throw out chips any grass, rotten material) has been fed
more. into the machine
The output tube is
jammed

Solution
Reverse or sharpen or change the blades - see 3.4 below
Remove branches thicker than 8 cm
Adjust the gap between fixed blade and counter blade: the correct gap is 0,5mm
Check that the start-switch on the engine is on "on" or "1".
Check if the emergency switch is de-activated.
Check oil and fuel levels
Contact your dealer
Shut off the engine and remove the key from the start switch. Remove the cap
from the rotor-axle. Turn the rotor a few degrees counter-clock-wise by means
of the special spanner. Block the rotor by blocking the special spanner on the
rotor axle behind the wheel axle. Remove material from the input tube by means
of a stick or tool and start the machine again. If need be, change the blades.
NEVER PUT YOUR HAND INTO THE INPUT TUBE OR ROTOR.
Shut off the engine, remove the spark plug cap. Block the rotor-axle by blocking
the special spanner behind the wheel axle. Dismount/remove the output tube.
Do not touch the blades, even if you are wearing gloves! There is a high risk of
cutting your hands badly. Remove debris with a stick or tool. Mount the output
tube again, tighten the screws firmly. Remove the special spanner from the axle.
Fit the cap on the rotor axle. Start the engine again.
