Damaged power cord
If the power cord is damaged, it must be replaced with an approved
cord that includes continuous line to ground (earth). Return unit to
Fogmaster or authorized importing distributor for service.
WARNING: A continuous ground (earth) line in the
power cord is essential for safe operation. Do not
operate machine without a continuous line to earth.
Replace motor
When excessive wear on the motor commutator shortens brush life
unacceptably, install a new motor (see “Simple Workstation”). Disconnect
motor wires and remove old motor, noting the sequence and orientation
of the plastic motor gaskets and metal torque ring.
Replace motor and reinstall gaskets and torque ring in proper
sequence. Take care that the bent tab on the torque ring faces the motor
and is seated in the small hole on the motor frame.
Reconnect electrical lines as shown on the circuit diagram.
Replace fan blade
Twisting the machine aggressively while it is running will cause the
fan blade to flex and scrape against the fan housing with a shrill, grinding
noise. Repeated flexing will eventually cause the fan to fail; the motor
operates but does not blow air.
To replace fan blade, open power head (see “Simple Workstation”)
and remove motor. Straighten the three bent tabs holding the fan housing
to the motor frame. Remove fan housing and unscrew the 1/2” nut hold-
ing fan blade to motor shaft. Replace fan blade (part number = 040) and
reassemble.
NOTE: You may have to remove motor brushes and the aluminum
armature bracket to grip the armature so it does not rotate when you
unscrew nut.
