29. DO NOT STOP COMPRESSOR BY PULLING OUT THE
PLUG
Use the "AUTO/OFF" knob of pressure switch.
30. 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.
SAFETY
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. If your units is
for use on less than 150 volts, it has a plug that looks like that
shown in sketch (A) in figure on the right. An adapter, see sketches
(B) and (C), is available for connecting sketch (A) type plugs to
two-prong receptacles. The green-colored rigid ear, lug, or the like
extending from the adapter must be connected to a permanent
ground, such as a properly grounded outlet box. NOTE: the
grounding adaptor, sketch (C), is prohibited in Canada by
Canadian Electrical Code Part.1. Therefore, the instructions for its
use are not applicable in Canada.
EXTENSION CORD
Use only three-extension cords that have three-prong grounding
type plugs and three-pole receptables 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 lenght and name plate ampere rating. If in
doubt, use the next heavier gage. The smaller the gage number,
the heavier the cord.

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 After having removed the compressor from its
packing (fig. 1) and having checked its perfect integrity, making
sure that it has not been damaged during transport, proceed as
follows.

COMPRESSOR WITH TANK (FIG.20)
Fit the wheels and the rubbers on the tanks where these have not
been fitted, following the instructions provided in fig. 2. Also fit the
air filter (fig. 2B) in compressors in which this has not been fitted.
COMPRESSOR WITHOUT TANK (FIG.21)
Fit the suction cups underneath the base of the unit as indicated in
fi g.2A. Position the compressor on a flat surface or one with an
inclination of 10° at the most (fig. 3), in a well-ventilated area away
from atmospheric agents and not in explosive areas. If the surface
is sloping and smooth, make sure that the compressor does not
move while running, otherwise block the wheels with two wedges.
If the surface consists of a shelf or the ledge of a stand, make sure
that it may not fall off by securing it appropriately. The compressor
must be positioned at least 50 cm away from any walls to ensure
its ideal ventilation and effective cooling. (fig. 4).
THIS COMPRESSOR RUNS WITHOUT OIL (4A)
OPERATIONAL INSTRUCTIONS
- Transport the compressor in the correct manner without tipping it or
lifting it with hooks or ropes. (fig. 5 - 6)
ELECTRICAL CONNECTION The single-phase compressors
are supplied complete with an electrical cable and two-pole + earth
power plug. The compressor must be connected to a power socket
provided with earth connection. (fig. 7)
The earth connection must be achieved according to the industrial
safety standards (EN 60204). The plug of the power supply cable
must not be used as a switch but must be plugged into a power
socket that is controlled by a suitable differential switch (magneto
thermal switch).
Make sure that the mains voltage corresponds to that indicated on
the electrical data nameplate (fig. 8), the admitted tolerance range
must remain within ± 5%.
COMPRESSOR WITH TANK (Fig. 20): Turn or press, depending
on the type of pressure switch fitted on the equipment, the knob
situated in the upper part to «0» (fig. 9). Put the plug in the power
socket (fi g. 7) and turn the knob to «I». Attach the rubber hose or
the spiral type hose to the appropriate fi tting situated near the
pressure switch (fig.25). The compressor runs in a completely
automatic manner and is controlled by the pressure switch that
stops it when the pressure inside the tank reaches the maximum
pressure and starts it again when the pressure falls back down to
the minimum level. The difference in pressure is usually 2 bar (29
psi) roughly between the maximum and minimum value. I.e.: the
compressor stops when it reaches 8 bar (116 psi) (max. running
pressure) and is automatically re-started when the pressure inside
the tank falls to 6 bar (87 psi). After having connected the
compressor to the electrical power supply line, load to the
maximum pressure and check the correct efficiency of the
machine.
COMPRESSOR WITHOUT TANK (Fig. 21): Put the plug in the
power socket (fig. 7). Press the starting push button situated at the
side of the compressor (fig. 9A). This type of compressor is
provided with a device that automatically controls the maximum
working pressure even if the user is not using compressed air.The
compressor automatically releases the excess air from a valve
situated on the head. The compressor does not stop automatically.
Use the ON/OFF push button to stop the compressor. Attach the
rubber hose or the spiral type hose to the appropriate fitting
situated at the top of the compressor, near the gear motor (fig. 25).
NOTE: The head/cylinder/delivery hose unit situated beneath the
panelling may reach high temperatures therefore be careful when
working near these components and do not touch them to avoid
getting burned (fig. 10).
