-----------------------------------------------------------------------------------------------------------------------------------------------
Symptom Possible Cause (s)
-----------------------------------------------------------------------------------------------------------------------------------------------
Compressor will not run 1. No electrical power
2. Blown fuse
3. Breaker open
4. Thermal overload open
5. Pressure switch faulty /
broken
-----------------------------------------------------------------------------------------------------------------------------------------------
Motor hums but cannot 1. Defective no-return valve
run or runs slowly or unloaded
2. Poor contacts, line voltage low
3. Shorted or open circuit motor
winding
-----------------------------------------------------------------------------------------------------------------------------------------------
Fuses blow/circuit breaker 1. Incorrect size fuse, circuit
trips repeatedly overloaded
CAUTION! Never use an 2. Defective no-return valve or
extension cord with this unloader
product
-----------------------------------------------------------------------------------------------------------------------------------------------
Thermal overload protector 1. Low voltage
cuts out repeatedly 2. Clogged air fi lter
3. Lack of proper ventilation/room
temperature too high
4. No-return valve malfunction
5. Compressor valves failed
5. Replace valve assembly
-----------------------------------------------------------------------------------------------------------------------------------------------
Knocks, rattles, excessive 1. Loose bolts, tank not level
vibration 2. Defective bearing on eccentric
or motor shaft
3. Cylinder or piston ring is worn
or scored

Corrective Action
1. Plugged in? Check fuse/breaker
or motor overload
2. Replace blown fuse
3. Reset, determine cause of problem
4. Motor will restart when cool
5. Replace
1. Replace or repair
2. Check connections, eliminate
extension lead if used, check circuit
with voltmeter
3. Replace motor
DANGER! Do not disassemble non return
valve with air in tank; bleed tank fi rst
1. Check for proper fuse, use time-delay
fuse. Disconnect other electrical
appliances from circuit or operate
compressor on its own branch circuit
2. Replace or repair
DANGER! Do not disassemble non return
valve with air in tank; bleed tank fi rst
1. Eliminate extension cord, check with
voltmeter
2. Clean fi lter (see Maintenance section)
3. Move compressor to well ventilated
area
4. Replace
DANGER! Do not disassemble non return
valve with air in tank; bleed tank fi rst
1. Tighten bolts, move tank to level
position
2. Replace
3. Replace or repair as necessary
1. Tighten
2. Disassemble no-return valve
assembly, clean or replace
3. Clean all connections with soap
and water solution and tighten
Ensure that the compressor draws clean
air
For the correct function and longevity of your air com-
pressor it is important that the air, which is drawn into
the compressor is clean. The compressor should not
be used in an area, where the air is contaminated
with dust or over-spray from spraying applications.

Securing the wheels to the frame

The wheels are secured to the lower frame on the
underside of the air receiver. To fi x the wheels to the
frame, put the fi xing bolt through each wheel and
then through the hole in the frame. Secure by means
of the washer and nut. The positioning of the wheel
can be seen in Fig 1.

The safety blow off valve

The compressor is equipped with a safety valve (see
fi g 1). If the pump were to continue operating passed
the maximum pressure, due to a defective pressure
switch, the safety valve would open and eject air from
the air receiver. If the safety valve discharges air,
please turn off the compressor and contact the help-
line. The safety valve is either located to the side of
the pressure switch as in Fig 1 or directly screwed
into the air receiver.
