Warning!
Disconnect power from power source before attempting to change the
sanding belt.
3) Pull the tension lever (A) Fig.12 completely to the left “loose” position as shown.
4) Remove the used sanding belt from both rollers.
5) The sanding belt runs counterclockwise on the rollers, before installing a new
sanding belt on the rollers, make sure the arrows on the inside of the sanding
belt correspond to the belt rotation label on the safety guard on the right side
of the machine.
6) Place and centre the new sanding belt around both rollers. Tension the sanding
belt by pulling the tension lever (A) Fig.12 completely to the right “tensioned”
position.
7) Reinstall the access cover and secure it with two lock knobs. Close both safety
guards and secure them with their retaining clips.
8) Once a new belt has been installed, check sanding belt tracking and adjust if
necessary.

Warning!
Disconnect power from power source before any maintenance
operations.
CHANGING GrAPHITe PAd ON THe STeeL PLATeN
The graphite pad (A) Fig.13 will wear down and will eventually require replacement
once visible signs of wear are apparent. To change graphite pad:
1) Following the instructions for removing the sanding belt.
2) Pull the old graphite pad (A) Fig.13 off the steel platen. A strong solvent may
be required to unglue the graphite pad from the steel platen.
3) Install a new graphite pad on the steel platen. Some graphite pads have
adhesive backings, some will require using contact glue.
TIMING beLT TeNSION AdJUSTMeNT/rePLACeMeNT
Over time the timing belts which transfer power from the motor shaft to the drive
roller for oscillation movement may require tensionning. Loose timing belts will
cause intermittant operation of the oscillation feature and cause excessive noise
and vibration. In such situation the timing belts will need to be tensioned.
1) Loosen hex. nut (A) Fig.14.
2) Turn the hex. bolt (B) clockwise then retighten the hex. nut (A).
3) If a timing belt should break and replacement is required, loosen and remove
four hex. bolts (C) under the motor assembly and remove the cover (D).
Replace timing belt(s). Reinstall cover.
LUbrICATION
SANdING beLT TeNSION MeCHANISM
It is important to keep the sanding belt tension mechanism (A) Fig.15 lubricated
and free of dust and debris. Clean mechanism and reapply all purpose grease to
the spring and shaft every 6 months or as needed.
