 Longer material standing out from the machine could
lash out when being pulled in by the knives! Please
keep at safe distance!
– Only insert as much material so that the chute assembly 8
will not be blocked up.
– Shred withered, moist material and garden waste which
has been stored for some days alternately with branches.
This prevents the cutting roller 16 from clogging.
– Do not fill soft waste such as kitchen rubbish into the
shredder but compost directly.
– Take care that the shredded material can fall freely from
the discharge chute – danger of backing up!
– The ventilation slots 3 must not be covered by the shred-
ded material.
– Avoid blocking the discharge chute with shredded material
as this could result in kickback of material through the
chute assembly 8 opening.
Advice on Shredding
Branches become harder to shred depending on the type, age
and dryness of the wood.

Troubleshooting

For best results, shred fresh branches soon after they have
been cut.
Soft garden waste should be shredded in smaller loads, par-
ticularly when wet. Any blockages can be avoided by intermit-
tently shredding branches.
Pressure Plate Adjustment (see figure H)
The pressure plate 15 is factory adjusted and may not require
adjustment before the first use.
Adjustment of the pressure plate 15 is necessary as a result of
wear (shredded material, e. g. branches, hangs together as a
chain and is not properly cut through).
With the motor running in the forward direction (green button
4), turn the adjustment knob 10 a small amount at a time in a
clock wise direction until a light grinding sound can be heard
(the cutting roller 16 cuts the pressure plate 15 to the proper
clearance, and some small aluminium shavings fall out of the
ejection chute).
To check, look for shavings in the collection box 11.
Readjust only to the required extent, otherwise the pressure
plate 15 could wear unnecessarily.
Possible Cause
Collection box not fitted correctly
Chute assembly not fitted correctly Fit chute assembly correctly
Mains socket faulty
Extension cable damaged
The machine is overheated
Fuse faulty/blown
Collection box/chute is not correctly
assembled
Undervoltage protection

in" and ready to use
Undervoltage protection

Corrective Action

Inspect cable, replace if damaged
Wait until the machine cools down

Ensure the collection box is in position
Ensure the chute assembly is in position and clamped
by turning the clamping knob (red) fully clockwise
Press the STOP button. Wait until the machine cools
down. The machine will beep for 2 seconds and switch
to standby.
Restart machine.
Check extension cable is as required in instructions
(lower quality extension cables can cause error)
