Problem

Possible Cause

Remedy

The machine does not start. The motor is not supplied

with the correct voltage.

• Check the power supply.

The motor is defective.

• Replace the motor.

The coupling (CPL) is de-
fective.

• Replace the coupling

(CPL).

The machine does not reach
the usual pressure on the
suction connection.

Oil level too low.

• Top up oil.

The inlet screen (IS) is par-
tially clogged.

• Clean the inlet screen (IS).

The inlet filter cartridge (op-
tional) is partially clogged.

• Replace the inlet filter

cartridge.

Internal parts are worn or
