MAINTENANCE
WARNING:
Always shut off and unplug the compressor and relieve all air pressure from the system
before performing any cleaning or inspection on the air compressor.
CLEAN AND INSPECT DAILY
1. Pull the pressure release valve ring to open the pressure release valve after each operation.
2. Open the tank drain valve underside the compressor to drain the tank daily after each operation. To minimize
moisture inside of the unit, tip the compressor during drainage so that the drain valve is aimed directly towards the
ground. This will allow all moisture to drain completely and prevent the tank from corrosion.
3. Wipe the tool clean. Blow the tool clean using high compressed air, then use non-flammable cleaning solutions to
wipe exterior of the tool as necessary, particularly before storage. Do not soak tool with cleaning solutions. Such so-
lutions can damage internal parts. Keep the handle clean, dry and free from slippery substances such as oil or grease.
4. Inspect the machine components before operation to make sure that there are no damaged or worn parts. Re-
place any damaged parts immediately. Do not operate if there are any damaged components. Only repair using
identical replacement parts.
5. Do not overtighten connections to avoid creating leaks.
CHECKING/CHANGING OIL
Check the oil level regularly from the oil gauge. The oil level must be between A
and B (Fig. 6). Do not overfill or underfill. When the oil level is below B, refill
with semi-synthetic compressor oil until the level reaches the center of the red
circle in the oil gauge.
Oil should be changed after 200 hours of operation. Prepare a container to catch the oil and unscrew the M6 oil
drain plug on the pump head. The compressor may need to be tipped slightly to let the oil drain completely. After
the oil has been drained, tighten the oil drain plug. Open the oil cap breather and fill the pump with semi-synthetic
compressor oil until the oil level reaches the center of the red circle in the oil gauge (Fig. 6).
NOTE: Dispose of the collected oil responsibly at a public collection facility.
TESTING FOR LEAKS
Make sure all connections are tight and secure before testing for leaks. A small leak in any hoses or connectors
will greatly reduce the abilities of the compressor. To locate a leak, simply spray a mixture of soap and water
across the entire surface of both the tank and the hose (wherever the leak is believed to be). Bubbles will begin to
appear if a leak is indeed present. Fix immediately. Try to avoid getting soapy water near any of the inlets on the
tank or the pump.
STORAGE
Before storing the compressor, drain the tank by opening tank drain valve on the underside of the compressor. This
will drain the compressor to prevent moisture from collecting and rusting the inside of the tank. Pulling on the air
release valve located next to the tank pressure gauge will quickly empty out the tank. Do not store in cold climates,
as cold climates may create problems with the motor while possibly freezing water condensation.
