To get the full range of table angling, handle must be very loose,
so that it slides along the slot in the table bracket. The table can
then be moved back to get maximum angles.
1. Loosen the table-locking Handle (#25).
2. Position the table back to the platen so there is about 1/16"
space between it and the belt.
Figure 21
3. Using a square, protractor or other 90° tool, measure the
angle of the table against the Platen (#67). Shown in
figure 21. Once the 90° is setting is found, lock it in place,
then adjust the hex Set Screw Stop (#80), that extends under
the table.
Figure 22
4. To set the table to a different angle, loosen the handle and
tilt the table forward until it is at the required angle. Shown in
figure 22.
5. Tighten the handle to lock the table in position for sanding.
V-Belt tension adjustments
Always ensure the sander is turned off
and unplugged prior to making any
adjustments to the machine.
If the sanding belt or disc slows down or stalls, the V-belt may
be slipping on the two pulleys. This may be because the motor
or frame has loosened from the base, or the V-belt has stretched
over time due to the machine use. In either case, re-adjustment
of the V-belt is needed.
1. To gain access to the V-belt, remove the V- belt rear metal
Safety Plate (#39) and V-Belt & Disc Guard (#37).
For clarity, figure 22 shows the V-belt and pulleys with the
metal sanding disc plate, table assembly and lower disc
guard removed.

2. Tilt the sander back, and slightly loosen the two hex head
Screws (#7) so that the sanding Frame (#64) can be moved
a bit forward or backwards to tension the V-belt as shown in
figure 23.
Figure 24
3. Position the frame so the tension on the V-belt is about 1/4"
to 1/2" deflection when moderate pressure is applied to the
belt. FIG. 30.
4. Tighten the hex head screws to secure the frame in its new
position on the base.
5. Re-install the safety guards over the V-belt, in step 1 above.
If needed, see page 7 for the installation process.
