OPERATION
Description of operation
WARNING:
Risk of Noise
•
Wear hearing protection to protect your
ears against exhaust noise and noise during
operation.
Drain valve:
The drain valve is located at the bottom of the air tank
and is used to drain condensation at the end of each use.
Thermal circuit breaker:
The electric motor has a manual reset thermal circuit
breaker. If the motor overheats for any reason, the circuit
breaker will shut off the motor. Turn the ON/AUTO - OFF
switch to the "off" position and wait for unit to cool before
pushing the reset button and restarting the compressor.
Motor thermal overload protector:
When the current rating of the motor is exceeded
the thermo-protector will open and shut off the motor
automatically. The motor must be allowed to cool down
before restarting. The compressor will automatically
restart after the motor has cooled down.
If you are using an extension cord, the compressor
shuts off even after performing above procedures. In this
case, the extension cord is too long or narrow. Replace
the extension cord with proper length and width.
ON/AUTO - OFF switch:
Turn this switch to "on" position to provide automatic
power to the pressure switch and to "off" position to
remove power when finished using the compressor or
when compressor will be left unattended.
WARNING:
Always turn off the ON/AUTO -
OFF switch when not in use.
CAUTION:
When carrying the tool, turn off the
ON/AUTO - OFF switch.
Air filter (Air intake):
Keep the air filter clean at all times. Do not operate the
compressor with the air filter removed. The compressor
does not operate at full capacity if the air filter is dirty.
Before using the compressor, always check the air filter
if it is clean. If not, clean the air filter or replace the filter
element.
Air compressor pump:
To compress air, the piston moves up and down in the
cylinder. On the down stroke, air is drawn in through the
air intake valve. The exhaust valve remains closed.
On the upstroke of the piston, air is compressed. The
intake valve closes and compressed air is forced out
through the exhaust valve, through the outlet tube,
through the check valve and into the air tank. Useable
air is not available until the compressor has raised the
air tank pressure above that required at the air outlet.
Check valve:
When the air compressor is operating, the check valve
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.
Pressure switch unloading valve:
The pressure switch unloading valve located on the
side of the pressure switch, is designed to automatically
release compressed air from the compressor head and
the outlet tube when the air compressor reaches "cut-
out" pressure.
Pressure switch:
The pressure switch automatically starts the motor
when the air tank pressure drops to the factory set
"cut-in" pressure. It stops the motor when the air tank
pressure reaches the factory set "cut-out" pressure.
Safety valve:
If the pressure switch does not shut off the air compres-
sor at its "cut-out" pressure setting, the safety valve
will protect against high pressure by "popping out" at
its factory set pressure which is slightly higher than the
pressure switch "cut-out" setting.
Outlet pressure gauge:
The outlet pressure gauge indicates the air pressure
available at the outlet side of the regulator. This pres-
sure is controlled by the regulator and is always less or
equal to the tank pressure.
Tank pressure gauge:
The tank pressure gauge indicates the air pressure in
the tank.
Regulator:
The air pressure coming from the air tank is controlled
by the regulator knob. Turn the knob clockwise to
increase pressure and counter-clockwise to decrease
pressure. To avoid minor re-adjustment after making
a change in pressure setting, always approach the
desired pressure from a lower pressure. When reducing
from a higher to a lower setting, first reduce to some
pressure less than desired pressure. Depending on the
air requirements of each particular accessory, the outlet
regulated air pressure may have to be adjusted while
you are operating the accessory.
Air outlet:
For regular pressure pneumatic tool, use outlet max
pressure; 0.93 MPa (9.3 bar).
Daily Start-up Checklist
WARNING:
Do not use the air compressor
if the switch does not turn it on and off. Any air
compressor that cannot be controlled with the switch
is dangerous and must be repaired.
Connecting hoses
WARNING:
Risk of Unsafe Operation
Firmly grasp hose in hand when installing
•
to prevent hose whip. Losing control of the
hose may result in personal injury and prop-
erty damage.
•
Always follow all safety rules recommended
by the manufacturer of hoses, connectors,
air tools, and accessories in addition to
all safety rules for the air compressor.
Following this rule will reduce the risk of
serious personal injury.
