AIR COMPRESSOR 11-GALLON (41.6 L) - 058-8386-8
How to shut down
1.
Set the pressure switch (C) to the
OFF
position.
2.
Unplug the power cord (K).
3.
Reduce the pressure in the tank through the outlet hose. Pulling the safety valve ring (D) and
keeping it open will also reduce the pressure in the tank.
CAUTION!
Escaping air and moisture can propel debris that may cause eye
injury. Wear safety goggles when opening the drain valve.
WARNING!
To avoid personal injury, always shut off and unplug the unit, and
relieve all air pressure from the system before performing any service on the air
compressor.
WARNING!
Risk of unsafe operation. Unit cycles automatically when power
is on. When performing maintenance, you may be exposed to voltage sources,
compressed air or moving parts. Personal injuries can occur. Before performing any
maintenance or repair, disconnect power source from the compressor and bleed off
all air pressure.

DESCRIPTION / REASON
SERVICE
INTERVAL
Drain the
tank
Through normal operation of your air compressor, condensation water will
accumulate in the tank. To prevent corrosion of the tank from the inside,
condensation must be drained at the end of every workday. Be sure to
wear protective goggles. Relieve the air pressure in the system and open
the drain valve on the bottom of the tank to drain. In cold conditions, it is
especially important to drain the tank after each use to reduce the chance
of problems resulting from the freezing of condensation water.
NOTE:
Refer to
To drain tank
, page 19.
Daily
Check
the valve
Pull/activate the safety valve daily to ensure that it is operating properly
and to clear the valve of any possible obstructions.
Daily
Clean the
air filter
A dirty air filter will reduce air compressor performance and life. To avoid
contaminating the pump, the filter should be cleaned frequently and
replaced on a regular basis. Clean the foam filter by immersing it in warm,
soapy water. Dry thoroughly after.
Weekly
Test for
leaks
Check that all connections are tight. Small leaks in the tank, hoses,
connections or transfer tubes will substantially reduce the air compressor
and tool performance. Spray a small amount of soapy water around
the area of suspected leaks with a spray bottle. If bubbles appear,
repair, replace or re-seal the faulty component. Do not over tighten any
connections.
Monthly
Storage
Before storing the air compressor, do the following:
•
Drain tank (see
Operating Instructions
paragraph in the
Maintenance
section of this manual for the correct procedure).
•
Use an air blow gun to clean all dust and debris from the compressor.
•
Disconnect and wind up the power cord.
•
Drain all moisture from the tank.
•
the
Pull
pressure safety valve to release all pressure from the tank.
•
Cover the entire unit to protect it from moisture and dust.
•
Store
the
air compressor in a clean and dry location.
•
In
cold weather, store the compressor in a warm building when it is
not in use. This will reduce problems related to starting the motor and
the freezing of water condensation.
