SAFETY GUIDELINES
ELECTRICAL SAFETY
Grounding instructions: In the event of a
malfunction or breakdown, grounding provides
the path of least resistance for electrical
2
current in order to reduce the risk of electric
shock. This tool is equipped with an electric
cord that has a grounding wire and a
grounding plug (1). The plug must be plugged
1
into a matching power supply outlet (2) that is
properly installed and grounded in accordance
MC-589308-01
with all local codes and ordinances, or a
grounded wall socket, for optimum
performance. The grounding plug has two
flat-blade terminals and a grounding pin.
If the grounding plug does not fit into the outlet, do not try to modify it. Have a qualified electrician
repair the proper outlet.
If the compressor's electrical cord requires repair or replacement, have this done by an authorized,
qualified service technician.
Guidelines for using extension cords
Note: Do not use the extension cord unless it is necessary. It is better to use a longer air hose that
reaches the work area where air is needed.
•
Use only a three-wired extension cord that has a three-prong grounding plug that fits into a
three-slot receptacle.
•
Ensure the extension cord is properly wired and in good electrical condition. Always replace a
damaged extension cord immediately or have it repaired by a qualified technician.
•
Protect the extension cords from sharp objects, excess heat and damp or wet areas.
•
Using extension cords with inadequately sized wires will cause a serious drop in voltage,
resulting in loss of power and tool damage. The smaller the gauge number, the heavier the
extension cord. If in doubt, select the next heavier gauge.
Note: Recycle unwanted materials rather than disposing of them as waste. When the tool is no
longer of use, sort the tool and its components in specific categories and take to the local recycling
center or dispose of them in an environmentally safe way.

IMPORTANT INFORMATION
General use
This Mastercraft Maximum® 5 U.S. Gallons (18.9 L) Air Compressor is designed to provide compressed
air to power air tools. This compressor is provided with an ON/OFF switch, an air tank and a motor with
automatic reset thermal overload protector.
Air compressor components
Air filter
The filter is attached to the compressor cylinder head for removing impurities from the air intake of
the compressor.
Air tanks
These air tanks are cylindrical components that are used to store the compressed air.
Check valve
This valve is an one-way valve that is connected between the air tank and pressure transfer tube to
prevent backflow of compressed air from the air tank to the compressor pump.
Drain valves
These valves are located at the bottom of the air tanks to drain moisture from the tank.
Pressure regulator knob
The knob can be adjusted to regulate the pressure at the air line outlet of the compressor. Turn the
knob clockwise to increase pressure and counter-clockwise to decrease pressure.
ON/OFF switch
This switch is operated manually to turn ON or OFF the compressor. When switch is in the AUTO
position, the compressor shuts down or starts up automatically based on air pressure level in the air
tank. Always set this switch to OFF position when the compressor is not being used and before
unplugging the compressor.
Pump
The pump is used to compress the air and discharge the compressed air into the air tank through a
reciprocating piston.
5 U.S. GALLONS (18.9 L) AIR COMPRESSOR 058-9308-0
12
This valve automatically gets activated if the compressor does not shut down automatically due to
high pressure in the air tank. To operate manually, pull the relief valve ring to relieve air pressure in
the tank.
Tank pressure gauge
The gauge indicates the pressure level of stored air in the air tank. It cannot be adjusted manually.
Thermal overload protector
This protector will automatically turn OFF the compressor if the temperature of the electric motor
exceeds a predetermined limit. If the thermal overload protector is activated, the motor must be
allowed to cool down before starting.
Outlet pressure gauge
The gauge is used to measure the regulated pressure at the air line outlet.
Effects of moisture in compressed air
Moisture in compressed air will form droplets when passing through the pump. When humidity is high
or when a compressor is in continuous use for an extended period of time, this moisture gets collected
in the air tank. If the compressor is connected to air tools for spraying applications, this water will flow
from the tank through the hose and outside the gun as droplets mixed with the spray material.
In paint spray application, water spots will be formed on painting surface due to condensation. In
sandblasting application, sand clumps will form and clog the gun, thereby causing the gun to be
ineffective.
Note: To reduce the moisture in compressed air, place a filter near the gun.

MAINTENANCE
Checking the safety relief valve
1.
Turn ON the power supply to the compressor and allow the motor to run until cut-off pressure
is reached.
2.
Pull the relief valve ring to check whether it is operating properly and to clear possible
obstructions of the valve.
3.
Replace the safety relief valve if it does not release pressure when pulling the ring.
CAUTION!
Potential hazard that may result in moderate injury or damage to
equipment.
•
Wear safety glasses when opening the drain valves and pulling the safety
valve ring, as the air and moisture released from the tank can propel debris
that may cause eye injury.
•
Do not direct the fast moving air from the tank toward your face.
•
If the safety relief valve does not work properly, over-pressurization may
occur, thereby causing air tank rupture or explosion.
Replacing the air filter
After continuous use of the compressor, the air
filter may get clogged. This will reduce the air
intake capacity of the compressor. Therefore it
is necessary to replace the air filter.
1.
Turn OFF the power supply to the
compressor.
2.
Remove the old air filter (1) from the
motor head (fig L).
3.
Install new air filter.
