Air Compressor Maintenance
Maintenance consists of keeping the air compressor clean.
Store the unit in a clean dry environment where it will not be
exposed to excessive dust, dirt, moisture or any corrosive
vapors. Cooling air slots in the air compressors engine must
not become clogged with dirt, leaves or any other foreign
material.
NOTE: DO NOT use a garden hose to clean air compressors
engine. Water can enter engine fuel system and cause
problems.
Cleaning Unit
Keep your air compressor clean and dry by placing it in a
location far away from sources of contamination. Make sure
the unit is kept in a well-ventilated area. Protect hoses,
connectors, quick connects, and accessories from damage.
To prolong compressor life, perform these steps weekly. If
the operating environment is particularly dirty, perform daily.
IMPORTANT: DO NOT use jets of water or flammable liquids
to clean unit.
1. With spark plug disconnected, use a soft cloth and a
small brush for cleaning accumulated dirt and debris
from the following locations:
• Cooling fins on top and sides of air compressor
pump, and engine blower housing slots (A).
• Oil fill locations and adjacent areas on both air
compressor pump housing and engine
• Oil drain plugs and adjacent areas on both air
compressor pump housing and engine
• Pressure control knob, gauges, quick connect
fitting, drain valves and safety valve
• Engine switch and adjacent area
• Choke lever, engine speed lever, fuel valve lever and
adjacent area on carburetor
• Spark plug and adjacent area
• Idle control valve and toggle
• Fuel tank cap and adjacent area
Inspect Safety Valve
1. Pull ring on safety valve (B) and observe that safety
valve operates freely.
2. If valve is stuck or does not operate smoothly, it must
be replaced with same type of valve. Take unit to
authorized service facility for repair.
Inspect Quick Connect Fittings and Tank Drain Valves
1. Turn off your air compressor as described in Stopping
your air compressor.
2. Disconnect air tool or accessory from unit. Inspect
quick connect fittings for damage and clean.
3. Pull ring on safety valve to reduce air pressure. Release
safety valve ring.
4. Open both drain valves (turn fully counterclockwise)
and permit accumulated water to be discharged. Valves
should operate smoothly and have full range of
operation.
5. After water has drained, close drain valves fully
clockwise.
NOTE: If drain valves are plugged, pull safety valve ring to
fully drain air from tanks. Remove, clean and reinstall drain
valves using pipe thread sealant.
