5.4 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 vis-
cous 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.
