Keep the grinding machine clean. Remove accumulated
saw dust from the cylinder and other moving parts. Re-
move sticking resin from the inner cylinder with a cloth
soaked in resin remover while the machine is disconnect-
ed from the power supply.
Warning: See to sufficient ventilation when working with sol-
vents. Do not use solvents to clean plastic parts.
A few fundamental rules have to be followed to guarantee
long-lasting and satisfying work with your grinding machine.
1 Lubricate the moving parts regularly with a lubricant,
which is not oil-based. Parts to be lubricated (among
others): thread depth adjustment, slide surfaces and
bronze bushes with depth adjustment mechanism. Do
not use oil or grease as these tend to attract and hold
wood dust.
2 Check the tight fit of the frame screws and motor/cyl-
inder mounting screws regularly.
3 Keep the grinding cylinder feed roll clean.
4 Only use clean grinding strips.
5 Check the alignment of the cylinder feeder belt and
table regularly. Re-align, if necessary.
Warning: Do not operate the machine when the cylinder cover
is opened. Be extremely careful during cleaning and main-
tenance works. Do not wear shirts with long sleeves, ties or
jewellery. Tie long hair in a net when cleaning the cylinder.
Otherwise, serious injuries may result.
Cleaning the grinding cylinder strips
During operation, the grinding strip gets choked with saw
dust, which leads to insufficient grinding power and burn-
ing of the work piece. Check the condition of the grinding
strip from time to time when the machine is switched off
and the mains plug is disconnected. This has to be done
more often when working with wood, which is highly res-
inous. Otherwise, the strip gets too choked and can no
longer be cleaned. Thus it has to be replaced.
1 Observe all warning signs and be extremely careful when
carrying out these cleaning works.
2 Put the speed regulator switch of the conveyor belt to
the lowest speed. Avoid any contact with the belt.
3 Open the protective cover to gain access to the grinding
cylinder and the grinding strip.
4 Use a long cleaning pole to keep your hands away from
the rotating cylinder.
5 Switch on the machine, hold the cleaning pole in both
hands and support yourself at the housing of the grind-
ing cylinder. Then, move the pole downwards towards
the rotating cylinder. Lift the pole from time to time to
remove the accumulated saw dust.
6 Remove the pole when the cleaning is completed,
switch off the machine and close the locking of the
protective cover.
Replacing the conveyor belt
Frequent causes that make a replacement of the conveyor
belt necessary are: normal wear, unintended contact with
the grinding strip during grinding, cracks caused by the
belt drifting sideways or excessive accumulation of a film,
which cannot be removed.
The following steps describe how to replace the conveyor
belt, if necessary.
1 Disconnect the machine from the power supply.
2 Lift the cylinder to its highest position (approx. 7.6 cm
over the conveyor belt table) with the height adjust-
ment handle.
3 Remove the two screws and star washers, with which
the front cover is mounted to the speed regulator box,
with a cross tip screw driver. Then, remove the front
cover by moving it to the left and over the outer drive
roll nut.
4 Remove the mounting screws of the conveyor table at
the outer open side of the machine with the supplied
6mm hexagon spanner.
5 Decrease the tension of the conveyor belt by turning
the inner as well as the outer belt adjustment screws
anti-clockwise.
6 Remove the old belt by gripping it with both hands at
both sides. Lift the conveyor table slightly at the same
time. If the belt cannot be lifted, further decrease the
tension to make sure that you can lift the table suf-
ficiently high and the belt can be removed.
7 Carry out steps 6 to 3 in reversed order to mount the new
belt. Centre the replaced belt on the conveyor table and
create an even tension with the inner and outer track
adjuster. Refer to the section „Track adjustment of the
conveyor belt“, if track problems occur.
