5.‐ OPERATION
To compress the air, the pistons move up down in the cylinder. On the down stroke, air is drawn
in though the valve inlet. The discharge valve remains closed. On the upstroke of the piston, air
is compressed. The inlet valve closes and compressed air is forced out through the discharge
valve, through the check valve and into the air receiver.
Air supply is not available until the pressure in the receiver has not raised the pressure required
by the connected tool.
The air inlet filter openings must be kept clear of obstructions, which could reduce air delivery of
the compressor.
5.1.‐ Tank safety valve
This valve is factory installed to prevent any damages due to a malfunction of the compressor. It
is factory set at a specific limit for your particular model and adjustment should never be
tampered by user, this will automatically void warranty.
From time to time, check the ring of the safety valve is not blocked. Change the safety valve in
case of need.
5.2.‐ Pressure switch
The air pressure switch is set at the factory to get the best performance from your equipment.
Do not ever bypass or remove this switch because this could cause serious damages to the
equipment and, or personal injuries could result due an air pressure too high. This switch is able
to be adjusted, but it is not allowed to get higher than 10 Bar, this adjustment is done by the
screw located under the cover of the pressure switch itself.
This pressure switch allows the compressor to run automatically, it stops it when max. pressure
is raised, and starts running again when the pressure is low.
Attention!!
Whenever you want to turn the machine off, first press the pressure switch
of and then unplug the plug from the power supply. If these steps are not followed, the pump
could suffer damages the next time the compressor starts running.
5.3.‐ Air receiver
Do not ever weld, perforate or make any changes to the tank, because it could lose its properties
and resistance.
Under the tank, you will find a drain device. From time to time, open this drain to remove water
result from inside condensation.
5.4.‐ Oil
This range of compressors does not need oil, which minimize maintenance controls and enlarges
the life time of the compressor.
