blades will also be evident on the underside of the fan cover. To correct this problem,
remove and reattach the cover.
NEVER operate the Comtec Model 1100 or Model 2200 without a cover over the
electric motor’s cooling fan.
5.2. Failing motor or pump
A failing motor bearing or hydraulic pump can cause a constant noise whenever the
machine is turned on. Additionally a failed motor bearing will typically cause the
electric motor to become excessively hot. Contact Comtec to see if a replacement
motor or pump is available for your machine.
5.3. Incorrect line voltage supplied to the machine
The operating voltage of each Comtec machine is stamped on the machine’s
nameplate. It is critical to the safe and proper operation of the machine that it is
supplied with the correct operating voltage. If the voltage is too low, the motor may
stall when pressing. If the voltage is too high, the motor or heating elements on the
machine can overheat.
Have qualified personnel measure the voltage at the outlet that the machine is plugged
into.
5.4. Motor is failing
While it is extremely rare, the electric motor on the press can fail, especially when the
machine has been dropped or poorly maintained. Symptoms of a failing motor can be
a motor that overheats, or a motor that stalls whenever the machine presses. Contact
Comtec to see if a replacement motor is available for your machine.
5.5. Blown fuse
The heating system of both the Model 1100 and the Model 2200 is protected by a 10A
fuse. NEVER operate the machine if this fuse has been bypassed or is missing. If the
dies on your machine don’t heat up, the fuse is the simplest item to check.
5.6. Failed thermostat
The temperature of the forming dies is regulated by a thermostat with a numbered dial.
When the thermostat is operating properly, the red “heating” light at the back of the
machine will turn off when the knob is rotated full counterclockwise. The light will also
turn on when the knob is rotated fully clockwise. If you have already checked the fuse,
and the orange light does not operate as stated above, then you should replace the
thermostat. Additionally, if you cannot rotate the knob, you should replace the
thermostat. Contact Comtec to see if a replacement thermostat is available for your
machine.
