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 opera-
tor from electric shocks. The compressor is equipped with a three-
conductor cord and three-prong grounding type plug to fit the proper
grounding plug socket. 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
Only use extension cords with three conductor cord that have three-
prong grounding type plugs and threepole that accept the compres-
sor's plug. Replace or repair damaged cords socket. 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 1 shows the correct size to use
depending on cord length and name plate ampere rating. If in doubt,
use the next heavier gauge. The smaller the gauge number, the heav-
ier the cord.
Tab.1 SECTION VALID FOR A MAX LENGHT OF 20 mt single-phase
Model Nr. 79-004
Avoid electrical shock hazard. Never use this compressor with a dam-
aged or frayed electrical cord or extension cord. Inspect all electrical
cords regularly. Never use in near water or in any environment where
electric shocks are possible

OPERATION AND MAINTENANCE
NOTE:
The information contained in this Instruction Manual is de-
signed 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 on the tanks on which are not
already fitted, observing the instructions in fig.1. In case of infiatable
wheels, the maximum inflation pressure must be of 1,6 bar (24 psi).
Position the compressor on a flat surface or with a maximum permissi-
ble inclination of 10°, in a well aired place protected against atmos-
pheric agents and not in a place subject to explosion hazard. If the sur-
face is inclined and smooth, check if the compressor does not move
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. To ensure good ventilation and efficient cooling, the
compressor's belt guard must be at least 100 cm from any wall (fig. 2).
USE INSTRUCTIONS
-
Take care to transport the compressor correctly, do not overturn it
or lift it with hooks or ropes
-
Replace the plastic plug on the guard cover (fig.3) with the oil level
stick (fig.5), supplied with the instructions booklet. Check oil level,
consulting the reference marks on the stick (fig.5).
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
Check that the mains power matches that indicated on the electrical
data-plate the permissible tolerance range is +/-5%.Press the knob

WARNING
STARTING
located on the upper section of the pressure switch to "0" position. Fit
the plug in the power socket and start the compressor,turning the
pressure switch knob into "I" position. The compressor is fully auto-
matic, 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 mini-
mum values is usually about 2 bar (29 psi).After connecting the com-
pressor to the power line, load it to maximum pressure and check ex-
actly how the machine is operating.
NOTE:
The electro-compressors must be connected to a power socket pro-
tected by a suitable differential switch (thermalbreaker). The compres-
sor motor is equipped with an automatic thermal breaker located inside
the winding - this stops the compressor when there motor temperature
reaches excessively high temperature. If the breaker is tripped, the
compressors restarts automatically after 10 to 15 minutes.
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). Pressure can be seen on the gauge.

Before attempting any maintenance jobs on the compressor, make
sure of the following:
-
Master power switch is in "0" position.
-
No pressure in the air tank.
Every 50 hours of duty, we advise you to dismantle the suction filter
and clean the filtering element by blowing compressed air on to it
(fig.11).You are recommended to replace the filter element at least
once if the compressor operates in a clean environment, but more fre-
quently if in a dusty environment. The compressor generates conden-
sation which accumulates in the tank.The condensation in the tank
must be drained at least once a week by opening the drain tap (fig.12)
under the tank.Take care if there is compressed air inside the cylinder
as water could flow out with considerable force. Recommended pres-
sure: 1 - 2 bar max. Condensation from of compressors that are oil
lubricated must not be drained into the sewer or dispersed into the en-
vironment as it may contain oil.
The compressor is filled with synthetic oil "SAE 5W50".We recommend
a full change of oil in the pumping element within the first 100 hours of
duty. Unscrew the oil drain plug on the housing cover, allow all the oil
to flow out and re-screw the plug (fig. 13).Pour oil into the upper hole
of the housing cover (fig. 15) until it reaches the level indicated on the
stick (fig.5). Once a week: check oil level of the pumping element and
see if it needs topping up. For operation at ambient temperature in the
range -5°C to +35°C, use "SAE 5W50" synthetic oil. The advantage of
this oil is that is does not lose its characteristics either in winter or
summer. Do not drain used oil into the sewer or dispose of it in the en-
vironment.
Other types of oil: mineral multigrade
Loss of air in valve under pressure switch
This can be caused by under tightening of the valve - take the follow-
ing action (fig.17):
-
Discharge all pressure from the tank
-
Unscrew the hexagon-head of the valve (A)
- 6-
The head/cylinder/delivery tube unit can reach high tempera-
tures. Take care when working near these parts, and do not
touch them to avoid possible burns (fig.8-9).
