Description Of Operation - Accuspray 93-116-SW Manuel D'utilisation

Drain Valve: The drain valve is located at the base of the air
tank and is used to drain condensation at the end of each
use.
Motor Thermal Overload Protector: The electric motor has
an automatic thermal overload protector. If the motor
overheats for any reason, the thermal overload protector will
shut off the motor. The motor must be allowed to cool before
restarting.
ON/AUTO - OFF Switch: Turn this switch ON to provide
automatic power to the pressure switch and OFF to remove
power at the end of each use.
Air Intake Filter: This filter is designed to clean air coming
into the pump. This filter must always be clean and ventila-
tion openings free from obstructions. See "Maintenance".
Air Compressor Pump: To compress air, the piston moves
up and down in the cylinder. On the downstroke, air is drawn
in through the air intake valves. The exhaust valve remains
closed. On the upstroke of the piston, air is compressed.
The intake valves close and compressed air is forced out
through the exhaust valve, into the outlet tube, through the
check valve and 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.
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" pres-
sure, the check valve "closes", allowing air pressure to remain
inside the air tank.
Pressure Release Valve: The pressure release valve located
on the side of the pressure switch, is designed to automati-
cally release compressed air from the compressor head and
the outlet tube when the air compressor reaches "cut-out"
pressure or is shut off. If the air is not released, the motor will

DESCRIPTION OF OPERATION

try to start, but will be unable to. The pressure release valve
allows the motor to restart freely. When the motor stops
running, air will be heard escaping from this valve for a few
seconds. No air should be heard leaking when the motor is
running, or continuous leaking after unit reaches cut-out
pressure.
Pressure Switch: The pressure switch automatically starts
the motor when the air tank pressure drops below 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
compressor at its cut-out pressure setting, the safety valve
will protect against high pressure by "popping out" at its
factory set pressure (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 pressure is controlled by the regulator and is always less
or equal to the tank pressure.
Tank Pressure Gauge: The tank pressure gauge indicates
the reserve 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 counterclockwise to decrease pres-
sure. To avoid minor readjustment 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 that desired,
then bring up to the desired pressure. Depending on the air
requirements of each particular accessory, the outlet regu-
lated air pressure may have to be adjusted while you are
operating the accessory.
