Adjusting or Replacing the Platen
1. Disconnect the electrical power to the machine to pre-
vent accidental start-ups.
2. Remove the top cover, side guard and belt as outlined in
Belt Replacement.
3. Remove the table by unscrewing the locking handling
and lifting the complete table assembly, from the machine.
4. If you are replacing the platen, remove the three screws
that hold it to its mount -- then install the new platen and
replace the mounting screws finger tight.
5. If you are only adjusting the platen, loosen the three
mounting screws to allow adjustment.
6. Using a straight edge as shown in Figure 22, adjust the
platen height until it is 1/32 inch higher than the crown of
both the drive and idler drums.
7. Tighten the platen adjustment screws.
8. Reinstall the table and belt.
9. Check and adjust, if necessary, the tracking of the belt
according to instructions in Belt replacement.
10. Reinstall the guards and covers.
11. Check and adjust the table angles and miter slot
squareness, according to table adjustment instructions in
this manual.
12. Reconnect the electrical power to the machine. Caution: Wilton sanders are available in a wide vari-
ety of electrical configurations to meet the needs of the
purchaser with respect to power available and compliance
with electrical codes. Each machine is tested at the factory
for operation before shipment and the power cord is tagged
with the power requirements for the machine, as shipped.
HOWEVER, before attempting any electrical hookup, you
should be certain:
1. The electrical characteristics of the service branch match
the requirements of the motor.
2. The service branch is equipped with wires of the re-
quired gauge or size.
3. The branch circuit intended for the machine is protected
with a time delay fuse or circuit breaker with a rated amper-
age just slightly greater than the full load current of the
motor.
