Operation - Campbell Hausfeld WL6500 Series Operating Instructions Manual

Oilless Compressors

Operation

Pressure Switch - Auto/Off Switch - In
the ON position, the compressor shuts
off automatically when tank pressure
reaches the maximum preset pressure.
The compressor will automatically
restart when it reaches the minimum
preset pressure. In the OFF position,
the compressor will not operate. This
switch should be in the OFF position
when connecting or disconnecting the
power cord from the electrical outlet
or when changing air tools.
Regulator - The regulator controls the
amount of air pressure released at the
hose outlet.
ASME Safety Valve - This valve
automatically releases air if the tank
pressure exceeds the preset maximum.
Handle - Designed to move the
compressor.
Tool Storage - 1/4 inch quick connect
couplers fit in holes to support air
chuck and other inflation fittings.
Never use the

handle on wheeled
units to lift the unit completely off the
ground.
MOISTURE IN COMPRESSED AIR
Moisture in compressed air will
form into droplets as it comes from
an air compressor pump. When
humidity is high or when a
compressor is in continuous use for
an extended period of time, this
moisture will collect in the tank.
When using a paint spray or
sandblast gun, this water will be
carried from the tank through the
hose, and out of the gun as
droplets mixed with the spray
material.
IMPORTANT: This condensation
will cause water spots in a paint
job, especially when spraying other
than water based paints. If
sandblasting, it will cause the sand
to cake and clog the gun,
rendering it ineffective. A filter in
the air line (MP3105), located as
near to the gun as possible, will
help eliminate this moisture.

Drain Petcock - This valve is located on
the bottom of the tank. Use this valve
to drain moisture from the tank daily
to reduce the risk of corrosion.
Reduce tank pressure below 10 PSI,
then drain moisture from tank daily to
avoid tank corrosion. Drain moisture
from tank(s) by opening the drain
petcock located underneath the tank.
LUBRICATION
This is an oilless product and DOES
NOT require lubrication to operate.
IMPORTANT: Do not operate compres-
sor before reading instructions or
damage may result.
1. Turn switch to OFF position and plug
in power cord.
2. Attach chuck or other tool to open
end of hose.

3. Turn regulator clockwise to open air
flow.
4. Turn switch to ON position.
5. Compressor will build to maximum
preset pressure and shut off.
6. Adjust regulator to proper pressure
for tool or tire. Operate tool per
instructions. Compressor will
automatically restart when pressure
in tank drops below cut-in pressure.
7. Turn regulator knob counterclock-
wise to shut off the air and turn
switch to Off position.
In the ON position, the compressor
pumps air into the tank. It shuts off
automatically when unit reaches its
maximum preset pressure. In the OFF
position, the compressor will not
operate. This switch should be in the
OFF position when connecting or
disconnecting the power cord from the
4
electrical outlet.
ASME SAFETY VALVE
Do not remove or
WARNING
!
attempt to adjust
the safety valve!
This valve should be checked under
pressure occasionally by pulling the ring
by hand. If air leaks after ring has been
released, or valve is stuck and cannot be
actuated by ring, it MUST be replaced.
Figure 7
REGULATOR KNOB
1. This knob controls air pressure to an
air operated tool, or paint spray gun.
2. Turning knob clockwise increases air
pressure at outlet.
3. Turning counterclockwise will lower
air pressure at outlet.
4. Fully counterclockwise will shut off
flow of air completely.
OUTLET (TOOL) PRESSURE GAUGE
1. This gauge shows at-a-
glance, air pressure at
outlet. Air pressure is
measured in pounds
per square inch (psi).
2. Be sure this gauge reads ZERO before
changing air tools or disconnecting
hose from outlet.
TANK PRESSURE GAUGE
Gauge shows pressure in
tank indicating
compressor is building
pressure properly.
WARNING
!
Disconnect power source
then release all pressure
from the system before
attempting to install,
service, relocate or perform any
maintenance.
