DeWalt DWFP55120 Instruction Manual page 9

When the air compressor is operating, the
check valve (G) is open, allowing compressed
air to enter the air tank. When the air compressor
reaches cut-out pressure, the check valve
closes, allowing air pressure to remain inside
the air tank.
TANK PRESSURE GAUGE
C The tank pressure gauge (B) indicates
B
D
the reserve air pressure in the tank.
OUTLET PRESSURE GAUGE
The outlet pressure gauge (C)
indicates the air pressure available at
the outlet side of the regulator. This
pressure is controlled by the regulator
and is always less than or equal to the tank pressure.
REGULATOR
The regulator (D) controls the air pressure shown on the outlet
pressure gauge. Turn regulator knob clockwise to increase
pressure and counterclockwise to decrease pressure.
DRAIN VALVE
The drain valve (F) is located at the base of the air
tank and is used to drain condensation at the end of
each use. See Draining Air Tank under Maintenance.
COOLING SYSTEM
This compressor contains an advanced design cooling system.
It is normal for this fan to blow air through the vent holes in large
amounts. The cooling system is working when air is expelled.
AIR COMPRESSOR PUMP
The pump compresses air into the air tank. Working air is not
available until the compressor has raised the air tank pressure
above that required at the air outlet.
MOTOR OVERLOAD PROTECTOR (NOT SHOWN)
The motor has 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.
G
TO RESTART:
1. Set the on/off switch to "O" and unplug unit.
2. Allow the motor to cool.
3. Plug the power cord into the correct branch circuit receptacle.
4. Set the on/off switch to "I" position.
