22. DO NOT WIPE PLASTIC PARTS WITH SOLVENT
Solvents such as gasoline, thinner, benzine, carbon tetrachloride,
and alcohol may damage and crack plastic parts. Do not
wipe them with such solvents. Wipe plastic parts with a soft cloth
lightly dampened with soapy water and dry thoroughly.
23. USE ONLY GENUINE REPLACEMENT PARTS
Replacement parts not original may void your warranty and can
lead to malfunction and resulting injuries. Genuine parts are
available from your dealer.
24. DO NOT MODIFY THE COMPRESSOR
Do not modify the compressor. Always contact the authorized
service center any repairs. Unauthorized modification may not
only impair the compressor performance but may also result
in accident or injury to repair personnel who do not have the
required knowledge and technical expertise to perform the repair
operations correctly.
25. TURN OFF THE PRESSURE SWITCH WHEN THE
COMPRESSOR IS NOT USED
When the compressor is not used, turn the knob of the pressure
switch "0" (OFF), disconnect it from the power source and open
the drain cock to discharge the compressed air from the air tank.
26. NEVER TOUCH HOT SURFACE
To reduce the risk of burns, do not touch tubes, heads, cylinder
and motors.
27. DO NOT DIRECT AIR STREAM AT BODY
Risk of injury, do not direct air stream at persons or animals.
28. DRAIN TANK
Drain tank daily or after 4 hours of use. Open drain fitting and tilt
compressor to empty accumulated water.
29. DO NOT STOP COMPRESSOR BY PULLING OUT THE
PLUG
Use the "O/I" (ON/OFF) knob of pressure switch.
30. PNEUMATIC CIRCUIT
Use recommended pipes, pneumatic tools that withstand a
pressure greater than or equal to the maximum operating
pressure of the compressor.
REPLACEMENT PARTS
When servicing use only identical replacement parts.
Repairs should be conducted only by authorized service center.
WARNINGS
GROUNDING INSTRUCTIONS
This compressor should be grounded while in use to protect the
operator from electric shock. The single-phase compressor is
equipped with a two-pole plus ground cable. The three-phase
compressor is supplied with power cord without plug. The electrical
connection must be carried out by a qualified technician. Never
disassemble the compressor or perform other connections in the
pressure switch. Any repairs must only be performed by authorized
service centers or other qualified centres. The green or green and
yellow conductor in the cord is the grounding wire. Never connect the
green wire to a live terminal. Before replacing the plug of the power
cord, make sure you have connected the ground wire. Should you
have any doubts, call a qualified electrician and check the ground
connection.
EXTENSION CORD
Use only extension cords that have three-prong grounding type
plugs. 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. The diameter of the extension cable of the
single-phase compressors must be in proportion to its length: see
table (tab 1).

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 (fig.1), 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, observing the instructions
in fig.2. In case of inflatable wheels, the maximum inflation pressure
must be of 1,6 bar (24 psi). Position the compressor on a flat surface
or with a maximum permissible inclination of 10° (fig. 3), 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. To ensure good
ventilation and efficient cooling, the compressor's belt guard must be
at least 100 cm from any wall (fig. 4). Compressors fitted on the tank,
with fixed feet, should not be rigidly secured to the ground. In this
case, we advise you to fit 4 anti-vibration supports.
USE INSTRUCTIONS
- Take care to transport the compressor correctly, do not
overturn it or lift it with hooks or ropes (fig. 5 - 6)
- Replace the plastic plug on the guard cover (fig. 7 - 8) with
the oil level stick (fig. 9) or with the relevant breather plug (fig. 10),
supplied with the instructions booklet. Check oil level, consulting
the reference marks on the stick (fig. 9) or the oil level inspection
window (fig. 11).
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 (fig.12).
