MAINTENANCE
UNIT CYCLES AUTOMATIOALLYWHEN POWER IS ON. WHEN DOING MAINTENANCE, YOU MAY BE EXPOSED
TOVOLTAGE SOURCES, COMPRESSEDAIROR MOVING PARTS. PERSONAL INJURIES CAN OCCUR. BEFORE
PERFORMING ANY MAINTENANCE OR REPAIR, UNPLUG THE COMPRESSOR AND BLEED OFF ALL AIR
PRESSURE.
ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE DONE BY
QUALIFIED SERVICE PERSONNEL.
Air Filter- Inspection and Replacement 10. Replaceconsolecover.
Safety Valve - Inspection
Hot surfaces. Risk of burn. Compressor
heads are exposed when filter cover is
removed. Allow compressor to cool prior
to servicing. _ _
Niter Retainer
NlteF
Keep the air filter clean at all times. Do not operate the
compressor with the air filter removed.
A dirty air filter will not allow the compressor to operate at
full capacity. Before you use the compressor, check the
air filter to be sure it is clean.
Check Valve - Replacement
Risk of personal injury. Mainfold assembly contains
compressed air which can be hazardous. Manifold
gets hot during operation.
Before servicing:
•Unplug or disconnect electrical supply to
compressor.
-Bleed tank of pressure.
•Allow compressor to cool.
1. Release al{ air pressure from air tank and unplug
outfit.
2. Remove console cover.
3. Loosenlower outlettube nut thatsecures outlettubeto
the upper manifold section.
4. Remove the six screws securing the upper manifold
section to the lower section.
5. Lift upper manifold assembly and invert so that the
flapper valve and o-ring are exposed.
6. Remove the two small screws securing the flapper
valve and restrictor.
7. Replace flapper valve and re-assemble restrictor and
two screws.
8. Assemble upper manifold assembly to the lower
section. Make sure the o-ring is retained in the upper
section as it is inverted and the outlet tube slides into
the upper section. Tighten six screws.
9. Tighten the lower outlet tube nut.
If the safety valve does not work properly,
over-pressurization may occur, causing air
tank rupture or an explosion. Before starting
compressor, pull the ring on the safety valve
to make sure that the safety valve operates
freely. Ifthe valve Is stuckor does not operate
smoothly, it must be replaced with the same
type of valve.
Motor
The motor has an automatic reset thermal overload
protector. If the motor overheats for any reason, the
overload protector will shut off the motor. The motor
must be allowed to cool down before restarting. The
compressor will automatically restart after the motor
COOLS.
If the overload protector shuts the motor off frequently,
check for a possible voltage problem. Low voltage can
also be suspected when:
1. The motor does not get up to full power or speed.
2. Fuses blow out when starting the motor; lights dim
Storage
Before you store theair compressor, make sure you do
the following:
1. Review the "Maintenance" and "Operating Proce-
dures" sections andperform maintenance as neces-
sary. Be sure to drain water from the air tank.
2. Protectthe electrical cord and air hose from damage
(such as being stepped on or run over). Wind them
loosely around the compressor handle.
Store the air compressor in a clean and dry location.
