quick connections;
These quick connection valves allow
outlet pressure regulation.
4. OPERATING
INSTRUCTIONS
This type of compressor is frequently
used in civil works, repairing shops
and industries. It provides compressed
air for several equipments, such as air/
painting guns and pneumatic tools.
When using the compressor, its user
must consider some safety measures:
� Do not touch the cylinders gasket,
cooling fins and compressed air
pipes, once these elements reach high
temperatures while operating. After
stopping the compressor wait some
minutes until the parts cool down;
� Never place any flammable, nylon or
cloth objects nearby and/or over the
compressor;
� The pipes or hoses connected to
the compressor must have the same
characteristics of flow and pressure.
At least they must be equal to the
compressor's technical specifications;
� Never switch on the compressor if the
air filter isn't assembled;
� Never change the safety valve neither
the tank.
� If there are any ball-type shutoff valves
in the compressor connections to the
stationary system, they must be opened
slowly. Never open the valve quickly
once it will release energy that may
damage equipments or tools;
� The compressor mustn't be switched
on
without
the
belt
otherwise it may cause physical or
goods damages;
� If the compressor is going to be used
on painting works, its user must be over
10m away from the equipment. It is
36
recommended to use the connection
hoses to work with enough distance
from the compressor;
� The compressor must only be set
into operation in environments with a
temperature between + 5°C e +45°C;
Before starting the compressor,
its user must ensure that all the
components are correctly assembled.
4.1 - COMPRESSOR START
AND STOP (FIG. F)
After carrying out all the assembly and
installation procedures, the compressor
is ready to operate. The initiation should
be carried out right after the installation
respecting the following order:
1. Check the oil level through the display
(24) and plug in the power cord;
2. Place the "ON/OFF" (28) switch,
on the power contactor box (7), in (I)
position;
3. Pull the power switch (17) to switch
the engine on:
- The engine will run until the tank is
completely full. When the tank reaches
its maximum pressure, displayed in the
pressure switch (16), the engine shuts
down automatically.
- When the engine shuts down, the
accumulated compressed air inside the
pipes between the compression pump
and the non-return valve is released.
This is the necessary condition to
prevent a restart with the engine in
effort. Therefore it prevents damages
and increases compressor's lifespan.
4. Press the power switch to stop the
engine and prevent an automatic start;
5. Open the condensates drain (26)
protection,
to drain the condensed water inside
the tank;
6. After draining out completely, close
the drain;
7. Connect the air guns and tools into
the quick connection valves (3) or into
the stationary system;
8. Pull the power switch to set the
compressor to operate;
- When turning the compressor ON,
if the tank pressure is inferior to the
minimum pressure indicated in the
pressure switch, the engine will start
immediately.
9. Check if there are any air leaks in
the pipes or connecting accessories.
If there aren't any tools or accessories
connected to the compressor or to the
distributing system and the compressor
starts systematically, it means that
there are leaks;
4.2 - PRESSURE SWITCH/
POWER SWITCH (FIG. G)
The compressor's automatic operation
is controlled by the pressure switch
(16). The compressor starts when
the minimum and maximum pressure
values are reached, as long as the
power switch's button is pulled up.
The minimum and maximum pressure
are established from factory, do not
change them.
The power switch connected to the
pressure switch (17) allows stopping
the compressor every time its user
intends to or in case of an emergency.
4.3 - SAFETY VALVE (FIG. G)
The safety valve (29) is prepared to
trigger according to the compressed
air tank admissible pressure (25). If for
some reason the admissible pressure
is reached (11) and the engine doesn't
stop, the safety valve shall open (14). It
is not allowed to adjust de safety valve
or to remove the plastic seal.
In order that the safety valve can
function correctly in case of need, it
must be activated frequently.
1. To make sure that the safety valve
