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). Also fit the Air Filter. 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).
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 (thermalbreaker).
STARTING
Check that the mains power matches that indicated on the electrical data-plate (fig.14) – the
permissible tolerance range is +/-5%. Turn or press into position "0" (according to the type of pressure
switch fitted on the appliance) the knob located on the upper section (fig. 15 & 15B). Fit the plug in the
power socket (fig. 12 - 13) and start the compressor, turning the pressure switch knob into position "I".
NOTE (Fig 15B): Position 'II' has no function on Bostitch compressor models.
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 (fig. 18 - 19).
IMPORTANT
The electro-compressors must be connected to a power socket protected by a suitable differential
switch (thermal-breaker). The motor of most compressor models (not PSV/BULLDOG) is equipped with
an automatic thermal breaker located inside the winding – this stops the compressor when motor
temperature reaches excessively high values (180 o C). If the breaker is tripped, the compressors restart
automatically after 10 to 15 minutes. The motors of compressor models PSV/ BULLDOG are supplied
with a manually resetting automatic amperometric thermal-breaker, located outside the terminal board
cover. When the breaker is tripped, wait for a few minutes and then reset the breaker manually (fig. 20).
