OPERATION
1. Start up
(1) Open the drain cock located at the lower part of
the tank (Refer to Fig. 8).
(2) Insert the plug into the receptacle.
(3) Start the compressor by pulling the knob of the
pressure switch to “ON” (Refer to Fig. 1 and Fig.
2).
(4) Close the drain cock.
WARNING: Do not stop or start the compressor
by use of the plug. Always use “ON/
OFF” knob located on the pressure
switch.
The operation of the compressor is automatic and is
controlled by the pressure switch which stops it when
the pressure in the air-tank reaches the maximum
level and restart it when the air pressure drops during
use to the restart level.
The motor of the compressor is fitted with a thermal
protection with manual reset (push-button), which
stops the compressor when the temperature is too
high. Should this be tripped, the compressor will
restart only if reset is done.
2. Adjustment of working pressure
Unlock the knob of the pressure reducer pulling it up,
adjust the pressure to the required level by turning the
knob clockwise to increase and counterclockwise to
decrease.
A pressure gauge (B) is provided to know when the
required pressure is reached, lock the knob by
pushing it down firmly (Refer to Fig. 7).
When adjusting the pressure, check and make sure
that a pressure gauge for the tank has the pressure
level that is higher than that of the pressure to be
adjusted.
It is also imperative that you make adjustment by
slowly starting up the pressure from the level that is
lower than the pressure to be adjusted.
WARNING:
Check the manufacturer’s maximum
pressure rating for nailers, staplers
and accessories. Compressor outlet
pressure must be regulated so as to
never exceed the maximum pressure
rating of the nailers, staplers and
accessories.
