TROUBLE SHOOTING
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.
- 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 millimetre)
- change or sharpen the blades &
counter-blade. Note: that the blades are
sharpened on both edges so they can be
reversed.
(this should be undertaken by
an approved service dealer only)
- shut the engine off & remove the branch
that is too thick
- adjust the gap between the blade & the
counter-blade in the slots.
The engine does not
start/ the engine shuts
off by itself
- electrical problem with
the engine.
- no fuel.
- insufficient oil in the
engine (refer to the
engine manual.)
Check that
- the input tube is correctly fitted & the
bolts are tight
- put the start-switch of the engine
“
on
”
- de-activate the emergency switch (turn
the knob)
- check oil & fuel levels (see engine
manual).
- contact your approved engine dealer.
The rotation assembly
jams.
The engine will not
start/ turn because the
rotation mechanism 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 rotation
mechanism after the
engine was last stopped.
- shut off the engine, remove the spark
plug cap and turn the rotation
mechanism counter-clock-wise. Use a
wooden stick to turn and to remove the
material from the mechanism and input
tube.
If necessary, remove the cap of the
bearing housing (fig. 6) and rotate the
mechanism axle with a spanner (fig 8)
If necessary, remove the input or output
tube to facilitate access to the rotor (fig. 7
& 8).
Check the sharpness of the blades and
counter blade and replace them if
necessary.
Important: screw back the blade bolts.
