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
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 lu-
bricant 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.

In order to access the radiator (1), open
the front or right panel. Regularly clean the
radiator in order to maintain its cooling ef-
ficiency at an acceptable level.
Remove any dirt particles from the radia-
tor using a fibre brush, then aim a jet of
compressed air at the radiator from the
bottom to the top; the jet should be held
at an approximate 90° angle to the plane
of the radiator.
