OPERATION AND USE
ADJUSTING THE PRESSURE SWITCH
(
Fig.5
):
Note: This is the only operation where it is
acceptable to switch the compressor off
without using the pressure switch.
To decrease the pressure switch, run the
compressor up to the desired capacity for the
pressure switch to be set. At this point, turn
the mains power off and do not operate the
red button on the pressure switch as this will
release the pressure. Disconnect the machine
from the power source before removing
cover
(D)
. With this removed, the adjustment
bolt
(C)
will be visible. Adjust this anti-
clockwise gently until the switch is heard to
release the pressure. Replace the cover and
tighten the screw. The switch will now be set
to the new pressure.
To increase the pressure switch, remove the
switch cover (having disconnected the
machine from the power supply) and turn the
adjustment bolt clockwise 3 turns and
replace the switch cover. Run the compressor
up to the desired capacity for the pressure
switch to be set (
do not
let the compressor
run past its maximum pressure). At this point
turn the mains power off and disconnect from
the supply. Remove the cover and adjust the
bolt anti-clockwise gently until the switch is
heard to release the pressure. Replace the
cover and tighten the screw. The switch will
now be set to the new pressure.
HOW TO ADJUST WORKING PRESSURE
(
Fig.6
):
See in the instruction manual for the rated
pressure value of the accessory you are going
to use.
By means of the pressure reducer
(G)
you
can adjust delivery air pressure. Turn the
knob clockwise to increase the pressure or
anti-clockwise to decrease the pressure.
Check the operating pressure value on
pressure gauge
(F)
.
After having used your compressor, set
pressure to zero by turning knob
(G)
so as to
avoid damaging the pressure reducer.
MAINTENANCE
OPERATION AND USE
- 7 -
- 8 -
Some of the operations listed in this section will require the compressor to be returned to an
Authorized Service Agent.
Before carrying out any service or routine operation to your compressor, ensure the power
has been disconnected and all pressure has been released from the tank, so as to prevent
any sudden unexpected restart. After any maintenance operation, make sure all components
have been fitted correctly.
OVERLOAD CUT-OUT (
Fig.7
):
The compressor is equipped with an overload
cut-out
(H)
which operates as a safety device
to protect the motor. In case of motor overload
or overheating due to operation troubles. The
safety device will automatically activate,
disconnecting the compressor and avoiding
possible motor damages.
To restart the compressor, proceed as follows:
- Allow three minutes.
- Position the pressure switch to"0" OFF.
- Manually reset the thermal cut-out.
- Position the pressure switch to "1" ON.
If you restart the compressor and the overload
cut-out releases again, turn the main switch to
position "0" OFF, unplug the equipment and
contact the Authorized Service Centre.
If disconnection is required from the air tap
assembly, ensure the tap is fully closed to stop
air loss from the tank.
NOTE: After reconnection is complete,
ensure that the tap is opened again.
It is essential to connect air line, air filter
separator and lubricator to ensure a good,
clean air supply is provided for the tool.
(NOTE: If the intended tool for use is a spray
gun, use only a filter separator as
lubrication will cause contamination of the
material being sprayed).

To ensure an optimum air supply, please
refer and carry out the following procedures
as recommended.
