position
Not sufficient air pressure
• Examine and adjust the system
pressures to the correct values,
refer to the Machine Specific
Information for pressure settings
The air line is bent or
blocked
• Repair any tight bends or
restrictions in the air lines
A fitting or tube
connection is loose
• Tighten loose connections
• Examine flow control fitting

does not run
No air flow
The motor overload relay,
OL-1, is in the tripped state
• Reset the exhaust fan overload
relay
• Examine FU-5 in the electrical
enclosure
Insufficient air flow
capacity in the factory air
ducts
• Install larger air ducts to increase
air flow
• Reset the exhaust fan overload
relay
The filter and
ducting are fine and
the motor
temperature is
normal.
The overload relay current
