Checking the oil level
WARNING! BEFORE SWITCHING ON
THE MACHINE FOR THE FIRST TIME,
the breather plug must be installed.
Remove the plastic transit plug (it’s
only a protective shipping plug) from
the oil filter hole and replace it with
the oil tank plug (breather) (13).
Before starting operation as well as during operating,
it is necessary to check oil level in the tank through
the inspection window (16). If oil level is low, then the
machine should be filled up with oil.
1. Place the machine on the clean flat surface.
2. Clean with a cloth the area around the oil tank plug
(13) and pull the oil tank plug (13) out.
3. Top up the oil tank with oil (do not exceed marks of
maximal level).
4. Reinstall the oil tank plug (13). [F2]
Lubricating oil must be clean. Apply only recommended
classes motor oil SAE30 if machine operates at
temperature over 10°C, and SAE10, if machine
operates at temperature lower than 10°C.
ATTENTION! Using the machine
without oil or with insufficient oil
volume is prohibited, as this may lead
to the machine being broken down
and can void the warranty.
SWITCHING ON/OFF
Switching on
∙ Connect the device to the power source.
∙ Move the on/off switch (10) upwards.
Switching off
∙ Move the on/off switch (10) downwards.
∙ Disconnect the plug from the socket.
WARNING! Never disconnect the plug
to stop the machine! Set the on/off
switch (10) in position OFF, instead!
OPERATING INSTRUCTIONS
∙
Install the machine on a dry rigid flat surface, thus
ensuring proper lubrication of the machine components.
∙
Make sure no water drops can reach the machine.
∙ The work area must be well ventilated.
∙ If it is necessary to transport the machine, first
switch it off, disconnect it from the power source and
release pressure from the receiver (2), afterwards,
transfer the machine.
∙ When not using the machine, switch it off, remove
the plug from the socket and discharge all the air in the
receiver (2) and the connected tools.
Automatic pressure switch (9)
The automatic pressure switch (9) keeps a constant
pressure value in the receiver (2), switching on or
switching off the electromotor of the machine, depending
on compressed air consumption by attached units.
At machine switching on, the compressor starts to pump
air into the receiver (2) through the pressure connector
(12).
After achieving the maximal pressure value (the value
of this parameter is set by the factory at the compressor
running), the automatic pressure switch (9) actuates
and the machine electromotor is deactivated.
Excessive air volume in the pressure connector (12)
and compressor pump (15) is released through the
non-return valve (26), so that there will be no excess
pressure in the compressor pump (15) and in the
pressure connector (12). In fact, the non-return valve
(26) prevents backflow of air from the receiver (2) to the
compressor head. This will reduce electromotor load at
the next start of the compressor.
When pressure drops to the minimal value, electromotor
will start operating and compressor will start pumping
air into the receiver (2), until the maximal pressure is
achieved.
If the automatic pressure switch (9) fails to actuate,
then overall pressure will be released through the
safety valve (11). Repair should be carried out by an
authorized IVT Service Centre.
Thermal protection (if present)
If the machine is equipped with thermal protection, this
device will switch off the electromotor at excessive loads
(for example, when the air filter (17) is clogged) and at
overheating. This prevents the machine electromotor
from excessive loads.
If the thermal protection is actuated, the machine
should be switched off, and the cause which led to the
protection actuating, should be eliminated. Then allow
the machine to cool off, before restarting the operation.
