5.7 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.
5.8 Servicing bearings of electric motor
When the compressor is used, fresh viscous lubricant (formulated for rolling bears) should be add-
ed to the motor's bearings. Lubricant should be added using a special syringe for viscous lubri-
cants through lubricators accommodated in the motor's bearing caps. The volume of lubricant
added can be calculated using the formula:
D 2
motor shaft
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.
