Instruction manual
∙
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 (10)
The automatic pressure switch (10) keeps a constant
pressure value in the receiver (2), switching on or switching
off the electromotor (4) 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 (13).
After achieving the maximal pressure value (the value
of this parameter is set by the factory at the compressor
running), the automatic pressure switch (10) actuates
and the machine electromotor (4) is deactivated.
Excessive air volume in the pressure connector (13)
and compressor pump (16) is released through the
non-return valve (31), so that there will be no excess
pressure in the compressor pump (16) and in the
pressure connector (13). In fact, the non-return valve
(31) prevents backflow of air from the receiver (2) to the
compressor head. This will reduce electromotor (4) load
at the next start of the compressor.
When pressure drops to the minimal value, electromotor (4)
will start operating and compressor will start pumping air into
the receiver (2), until the maximal pressure is achieved.
If the automatic pressure switch (10) fails to actuate,
then overall pressure will be released through the
safety valve (12). 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 (4) at excessive
loads (for example, when the air filter (18) is clogged)
and at overheating. This prevents the machine
electromotor (4) 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.
Adjusting the pressure
Pressure reducer (24)
The pressure reducer (24) allows adjusting outlet air
pressure in the connection nipple (3) of the controlled
pressure pipeline, depending on consumption.
Set required working pressure, - pressure value should
be read on pressure gauge (6):
∙
to decrease pressure: turn the pressure reducer
handle (5) counterclockwise.
∙
to increase pressure: turn the pressure reducer
handle (5) clockwise.
[F3]
NOTE: the machine design provides the adjustment of
compressed air output pressure only in the nipple (3) of
the controlled pressure pipeline. Output pressure in the
pipe connector (8) is equal to receiver (2) pressure value;
pressure value should be read on pressure gauge (9).
MAINTENANCE AND STORAGE
Before any work on the device itself,
pull the mains plug.
∙
Always keep the tool and the ventilation slots (if
present) cleaned. Regular cleaning and maintenance of
the appliance will ensure efficiency and prolong the life
of your tool.
∙
If the tool should fail despite the rigorous
manufacturing and testing procedures, the repair should
be carried out by an authorized IVT customer service.
∙
Keep all nuts, bolts, and screws tight, to be sure the
tool is in safe working condition.
∙
Replace worn or damaged parts for safety.
∙
Use only original spare parts. Parts not produced
by manufacturer may cause poor fit and possible injury.
∙
Store the tool in a dry room out of reach of kids and
away from any flammable material.
∙
Never wet the device or spray water on it!
CAUTION! Prior to starting any
procedure, the machine should be
obligatory disconnected, power cable
should be taken out from the socket and
receiver (2) pressure should be released
(pull the ring of safety valve (12)).
Cleaning the machine
Exterior surfaces of the device should be cleaned after
operation with a soft brush and cloth.
Do not use caustic substances or solvents for cleaning
the machine.
Changing the oil
Regularly check the condition of the oil (every 6 months).
It is necessary to change the oil after the first 30 hours
of machine operation.
