MAINTENANCE & TROUBLESHOOTING
MOTOR
Excessive dust in the motor could cause excessive heat in the
motor. Every effort should be made to prevent foreign material from
entering the motor. A visual inspection should be made at frequent
intervals. Accumulations of dry dust can usually be blown out to
prevent the interference with normal motor ventilation. To remove
dust, blow off motor with a low pressure air hose.
CAUTION:
TO AVOID INJURY OR ADVERSE REACTION TO
DUST, A HIGH PRESSURE HOSE SHOULD NOT BE USED
ESPECIALLY IN POORLY VENTILATED AREAS.
The operator performing this cleaning function should wear
safety glasses and a filter mask. If any servicing (other than the
above cleaning) becomes necessary, it should be performed by an
authorized service center.
Operational hints
During the first use and after cleaning, the filter bag may allow
some dust to escape. This is normal and will stop after a short
period of time.
CAUTION:
WEARING A PARTICLE MASK/RESPIRATOR FOR
PROTECTION AGAINST FINE DUST PARTICLES DURING
CLEANING IS HIGHLY RECOMMENDED.
Clean both the filter and the collection bags frequently to keep the
dust collectors’ performance at its optimum. To clean:
1. Disconnect the machine from the power source.
2. Loosen the retaining straps, remove the bags from the housings
and empty contents.
3. Turn the bags inside out and shake vigorously.
4. Turn the bags inside in and reattach to the housings using the
retainer straps to secure.
5. Connect the machine to the power source.
Use the proper type of hose to connect the dust collector to the
machine being operated. A dryer vent hose is not acceptable for
this purpose.
PROBLEM
Motor will not run.
Excessive sawdust in
air.
Excessive impeller
noise.
Excessive noise.
Motor fails to develop
full power.
NOTE: LOW VOLTAGE
(Power output of motor
decreases rapidly with
decrease in voltage at
the motor terminals.
Motor starts slowly or
fails to come up to
speed.
Motor overheats
PROBABLE CAUSE
1. Defective cord, plug, switch
and/or motor.
2. Blown fuse.
1. Loose connectors.
2. Filter/dust bag and/or chip col-
lector bag releasing sawdust.
1. Picked up large wood chips
and debris.
2. Loose impeller.
3. Rubbing impeller.
1. Motor.
1. Circuit overloaded with
lights, appliances and other
motors.
2. Undersized extension cord or
extension cord is too long.
3. General overloading of power
company facilities.
1. Low voltage.
2. Windings are burned out or
open.
3. Starting switch will not
operate. Capacitor is bad.
1. Motor overloaded.
2. Improper cooling, air
circulation is restricted
through motor due to
sawdust accumulation.
REMEDY SUGGESTED
1. Consult service. Any attempt to repair this motor may create a hazard unless
repair is done by a qualified service technician. Repair service is available at
your nearest service center.
2. Check for blown fuses and replace with fuse of proper capacity.
1. Tighten connections.
2.a. Sawdust trapped between clamp bag and dust filter.
b. Lower bag is hung up on sawdust shoot extension. Reposition chip bag properly.
1. Do not pick up metal or ferrous materials. Stop the machine and the material
will fall to the bottom of the inlet tube.
2. Unplug dust collector prior to disassembly. Hazardous moving parts inside.
Attach inlet guard before plugging in. Use a piece of wood to free impeller.
3. Consult service to repair loose or rubbing impeller. A repair to the housing may
create a hazard unless it is done by a qualified service technician. Servicing is
available at your nearest service center.
1. Have the motor checked by a qualified service technician.
1. Do not use other appliances or motors on the same circuit as your dust collec-
tor.
2. Increase the wire size on extention cord, or reduce the length of the extension
cord.
3. Request a power check from your power company.
1. Request voltage check from your power company.
2. Have motor repaired or replaced by a qualified service technician.
3. Have capacitor replaced by a qualified service technician.
1. Clean out sawdust to provide normal air circulation through the motor. See
‘’Maintenance’’ section in this manual.
