• Remove the two screws securing pulley guard, and remove the pulley guard. Inspect
the inside of the guard for signs of contact with the pulleys.
• Loosen the four bolts securing motor. Do not remove the bolts, simply loosen them to
allow the motor to move freely back and forth in its milled slots.
• Using an Allen wrench, loosen the pulley set screws on the drive pulley. Slide the motor
towards the outfeed end of the machine, allowing the belt to slip off the pulley. With
the drive belt out of the way, remove the pulley from the motor drive shaft
• With the drive pulley and motor bolts removed, the motor can be now be pulled from
the machine. Depending on the model, there will either be two or four wires still
connecting the DB15 connector to the machine. These wires will be for the air valve
and the cutoff switch (depending on model).
• Using a pair of wire cutters, cut the wires going to the air valve. It is recommended to do
this between the wire splice and air valve, as close to the splice as possible.
• If your machine is equipped with a cutoff switch, the terminals connecting to the cutoff
switch will be spade terminals and can simply be removed by pulling on the connectors
at the switch.
• The new motor assembly will be shipped with a new DB15 connector and harness. It will
have splices ready to crimp to the air valve wires. The air valve is Alternating Current, so
wire orientation is not important. We recommend installing the DB 15 connector first
using the jack screws and nuts. Reinstall spade terminals to cutoff switch if so equipped.
Cutoff switches have three terminals: Common, normally open, and normally closed.
The wires should be connected to common and normally open. These are the bottom
two terminal connections.
• After connecting the air valve wires, insert the new motor into the machine body. The
shaft of the motor will be ready to accept the drive pulley. Leave the four motor bolts
slightly loose.
• Tighten the pulley set screws and secure with a drop of blue Loc-Tite or other thread
locker. Do not overtighten.
• With the pulley installed, slide the motor back towards the outfeed end. Loop the drive
belt over the pulleys. Slide the motor towards the infeed end to tension the belt, and
tighten the four motor bolts.
• Replace the pulley guard. The new motor is now ready for use.
Thermostat, heater cord and heating element testing
• Turn power to machine off.
• Insert AC volt meter into heater cord outlet on back of control panel. Turn power on.
• Rotate thermostat from zero (off) to 10 (full power). You should read an output
equivalent or close to that of the nominal input voltage. In most U.S. Locations, this will
be around 120 Volts AC on the meter.
• Rotate thermostat back towards zero (off) position until it clicks again, you should read
0 Volts AC on the meter.
• If no voltage is present at outlet during the above test, check for voltage to thermostat.
If voltage is present then the thermostat is bad.
