Remove 2 screws securing belt safety cover and remove cover to expose the drive belt
(see Fig. 19& 20).
Whilst rotating the blade cylinder by hand, ease the belt off the small pulley by applying
side pressure to the belt as the pulley rotates.
Remove the belt, working it between the large pulley and the left hand guide shaft
spring.
IMPORTANT
When carrying out this procedure, it is recommended that a pair of good quality
industrial gloves is worn to protect against cuts etc. Also take care fingers are not
trapped between the belt and pulleys.
When fitting new belt, ensure the belt is centralised on both pulleys, and that all the
grooves in the pulleys are used.
With the new belt in situ, reassemble the machine in reverse order, taking care to fit all
lockwashers etc, and ensuring all screws etc are tightened sufficiently, DO NOT
overtighten.
After fitting new belt or blades, when first starting the machine allow it to run for a couple
of minutes before attempting to use it. If any unusual noises or excessive vibration is
detected, switch off and isolate from the main electrical supply by removing the plug
from the socket.
Investigate the cause and rectify before
attempting to switch on and use again.
Anti Kick back Mechanism
The effectiveness of the device for the
prevention of kickback should be
regularly inspected to ensure safe
operation.
The kick back claws are located at the
front of the machine (see Fig. 21).
Ensure all the claws are in place, not
broken, and move freely on the shaft, if
any claws are broken or missing, these
must be replaced before using the
thicknesser again.

Dust Extraction
The thicknesser is provided with a dust extraction facility, where a vacuum extractor or
dust bag may be connected. An adapter is provided for this
purpose, and must be fitted at all times whether using dust
extraction or not, this is a safety requirement which prevents
finger access to the blades.
The adapter fitting is a bayonet type and is simply fitted by
pushing onto the outlet port on the rear of the machine and
twisting clockwise, once in position, the adapter must be
secured in position by tightening both screws, Do Not
overtighten.
Please note however, using dust extraction does not preclude the user
from wearing a face mask to prevent the inhalation of dust particles.

3. Place straight edge across the centre
of the base plate and the infeed roller
Fig. 3c, there should now be a gap
between the straight edge and infeed
roller. Whilst holding the straight edge
flat on the base plate, slowly turn one
of the allen screws B Fig. 3b in a
clockwise direction, keep turning
screw until the roller is just clear of the
straight edge. Gently tighten the
locknut ensuring the allen screw
doesnt move, check with straight
edge the roller is still clear, if not readjust.
Carefully turn the other allen screw clockwise until it just touches the bracket
without raising the roller, tighten the locknut ensuring screw doesnt move, recheck
the roller is just clear of the straight edge, check both ends as well as the centre, if
necessary readjust as required.
Once satisfied the roller is just clear of the straight edge along its full length, carefully
ensure both locknuts are firmly tightened, ensuring the allen screws do not move.
4. Whilst holding the straight edge flat across one end of the base plate and roller,
loosen the corresponding screws A Fig. 3a and adjust the roller so that it just touches
the straight edge, carefully tighten screws, repeat for other end.
Recheck other end and adjust if necessary.
Once satisfied the roller is level with the base plate, carefully ensure all screws and
nuts are securely tightened.
Once all screws and nuts are tight, recheck and if necessary readjust as required.
Repeat steps 1 - 4 for the outfeed roller.

2. Loosen locknut and unscrew allen screws B Fig. 3b approx
4 full turns anticlockwise.
Repeat for other side, infeed roller should now lower as the
second screw is turned.
