Open drain fitting and tilt compressor to empty accumulated
water.
28. DO NOT STOP COMPRESSOR BY PULLING OUT THE
PLUG
Use the "AUTO/OFF" knob of pressure switch.
29. USE ONLY RECOMMENDED AIR HANDLING PARTS
ACCEPTABLE FOR PRESSURE NOT LESS THAN 125 PSI
(8.6 BAR)
Risk of bursting. Use only recommended air handling parts
acceptable for pressures not less than 125 psi (8.6 bar).
REPLACEMENT PARTS
When servicing use only identical replacement parts.
Repairs should be conducted only by authorized service center.
GROUNDING INSTRUCTIONS
This compressor should be grounded while in use to protect the
operator from electric shock. The compressor is equipped with a
three-conductor cord and three-prong grounding type plug to fit
the proper grounding type receptacle.
The green (or green and yellow) conductor in the cord is the
grounding wire. Never connect the green (or green and yellow)
wire to a live terminal.
EXTENSION CORD
Use only three-extension cords that have three-prong grounding
type plugs and three-pole receptacles that accept the
compressor's plug.
Replace or repair damaged cord. Make sure your extension cord
is in good condition. When using an extension cord, be sure to use
one heavy enough to carry the current your product will draw. An
undersized cord
will cause a drop in line voltage resulting in loss of power and
overheating.
Table shows the correct size to use depending on cord length and
name plate ampere rating. If in doubt, use the next heavier gage.
The smaller the gage number, the heavier the cord.
For 3 HP/2.2 kW and voltage 220/230 V, the section of the
extension cord must be 2.5mm².
WARNING
Avoid electrical shock hazard. Never use this compressor with a
damaged or frayed electrical cord or extension cord. Inspect all
electrical cords regularly. Never use in near water or in any
environment where electric shock is possible.

OPERATION AND MAINTENANCE
NOTE: The information contained in this Instruction Manual is
designed to assist you in the safe operation and maintenance of
the compressor.
Some illustrations in this Instruction Manual may show details or
attachments that differ from those on your own compressor.
INSTALLATION
Remove the compressor from its packing, makes sure it is in
perfect condition, checking if it was damaged during transport,
and carry out the following operations. Fit the wheels and rubber
tab on the tanks on which they are not already fitted.
Position the compressor on a flat surface or with a maximum
permissible inclination of 10°, in a well aired place, protected
against atmospheric agents and not in a place subject to
explosion hazard. If the surface is inclined and smooth, check if
the compressor moves while in operation – if it does, secure the
wheels with two wedges. If the surface is a bracket or a shelf top,
make sure it cannot fall, securing it in a suitable way.
USE INSTRUCTIONS
– Take care to transport the compressor correctly, do not overturn
it or lift it with hooks or ropes,
– Check oil level, consulting the reference marks on the stick or
the oil level inspection window.
ELECTRICAL CONNECTION
Single-phase compressors are supplied with an electrical cable
and a two-pole + earth plug. The compressor must be connected
to a grounded power socket.
10
IMPORTANT:
Never use the ground socket instead of the neutral wire. The
ground connection must be made to meet safety standards (EN
60204).
The plug of the power cable must not be used as a switch, but
must be fitted in a power socket controlled by a suitable
differential switch (thermal breaker).
Check that the mains power matches that indicated on the
electrical data-plate – the permissible tolerance range is +/-5%.
Press into position "0" the knob located on the upper section.
Fit the plug in the power socket and start the compressor, turning
the pressure switch knob into position "I". The compressor is fully
automatic, and is controlled by the pressure switch which stops it
when tank pressure reaches maximum value and restarts it when
it falls to minimum value. The pressure difference between
maximum and minimum values is usually about 2 bar (29 psi).
E.g.: the compressor stops when it reaches 8 bar (116 psi –
maximum operating pressure) and restarts automatically when
the pressure inside the tank drops to 6 bar (87 psi).
After connecting the compressor to the power line, load it to
maximum pressure and check exactly how the machine is
operating.
NOTE: The head/cylinder/delivery tube unit can reach high
temperatures. Take care when working near these parts, and do
not touch them to avoid possible burns.
IMPORTANT
The electro-compressors must be connected to a power socket
protected by a suitable differential switch (thermal-breaker).
ADJUSTING OPERATING PRESSURE
You do not have to use the maximum operating pressure at all
times. On the contrary, the pneumatic tool being used often
requires less pressure.
On compressors supplied with a pressure reducer, operating
pressure must be correctly adjusted. Adjust pressure to the
required value by turning the knob clockwise to increase pressure
and anti-clockwise to reduce it.
MAINTENANCE
Before attempting any maintenance jobs on the compressor,
make sure of the following:
– Master power switch in position "0".
– Pressure switch and the control unit switches all off, in position
"0".
– No pressure in the air tank.
You are recommended to replace or clean the air filter element at
least every 50h if the compressor operates in a clean
environment, but more frequently if in a dusty environment.
To clan this air filter: dismantle the suction filter and clean the
filtering element by blowing compressed air on it.
The compressor generates condensate water which accumulates
in the tank.
The condensate in the tank must be drained at least once a week,
by opening the drain tap under the tank.
Take care if there is compressed air inside the cylinder, and water
could flow out with considerable force.
Recommended pressure: 1 – 2 bar max.
Condensate of compressors that are oil lubricated must not be
drained into the sewer or dispersed in the environment as it
contains oil.
OIL CHANGES – TOPPING UP WITH OIL
Unscrew the oil drain plug on the housing cover, allow all the oil to
flow out, and re-screw the plug.
Pour oil into the upper hole of the housing cover until it reaches
the level indicated on the stick or indicator. Pour oil into the upper
hole of the head.
Once a week: check oil level of the pumping element and see if it
needs topping up.
WHAT TO DO IF SMALL MALFUNCTIONS OCCUR
Loss of air in valve under pressure switch
This trouble depends on poor tightness of the check valve – take
the following action:
- Discharge all pressure from the tank
