5.9 Checking suction valve
In order to access the intake valve, the air filter has to be removed in accordance with
section 5.5.
Then open the air throttle by hand, ensuring that it has a smooth stroke and can be opened fully.
If the air throttle jams or
doesn’t operate fully, then replace the valve with a new one.
5.10 Servicing bearings of electric motor
When the compressor is used, fresh viscous lubricant (formulated for rolling bears) should
be added to the
motor’s bearings.
Lubricant should be added using a special syringe for viscous lubricants through lubricators
accommodated in the
motor’s bearing caps.
The volume of lubricant added can be calculated using the formula:
D2
motor shaft
( mm ) х 0,005 = М
(lubricant mass)
( g ).
Do not over-lubricate the bearings beyond the standard level as all excess lubricant will be
squeezed out of the bearings into the motor when the motor is running.
6. Fault handling
6.1 Faults and corrective actions
Problem Possible faults Corrective actions
The compressor starts up with
lag. There is a slow build up in
the electric
motor’s speed.
The belt is overtightened
Tighten the belt with the rel-
evant load.
The oil is thick. Replace the oil.
There’s a whistling during the
compressor’s operation.
The belt is slipping.
Tighten the belt with the appro-
priate tensile force (see section
5.3 Checking drive belt).
The compressor won’t start.
There’s a temperature block on
the control unit’s display.
The ambient air temperature in
the facility does not meet the
required temperature (below
+5 °C or above +40 °C).
Ensure the necessary ambi- ent
air temperature where the com-
pressor is installed.
The compressor is overheating.
There’s insufficient ventilation in
the facility where the compres-
sor is installed.
Increase the air circulation
inside the facility.
The oil level is too low. Top up oil.
The radiator is dirty Blow down the radiator with
compressed air.
