Comprag А3713 [29/92] Servicing bearings of electric motor

COMPRAG Screw air compressor A-Series

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

lly.

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:

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.
