– Only use original spare parts or parts of matching quality for the engine. Using spare parts of

lower quality can seriously damage the engine.

– See also the SAFETY RULES in the Engine Manual, which is to be considered an integral part of

this Manual.

– Pay attention to hot parts when working near the engine and the mufer.

(For SW900 B)

– Before using the battery charger, ensure that frequency and voltage values, indicated on the

machine serial number plate, match the electrical mains voltage.

– Do not pull or carry the machine by the battery charger cable and never use the battery charger

cable as a handle. Do not close a door on the battery charger cable, or pull the battery charger

cable around sharp edges or corners. Do not run the machine on the battery charger cable.

– Keep the battery charger cable away from heated surfaces.
– Do not use the machine if the battery charger cable or plug is damaged. If the machine is not

working as it should, has been damaged, left outdoors or dropped into water, return it to the

Service Center.

– Before performing any maintenance procedure, disconnect the battery charger cable from the

electrical mains to avoid any risk of re, electric shock or injuries.

– Do not smoke while charging the batteries.

Dust Control System

Functional Description

The dust generated in the compartment of the main
broom is drawn toward the lter from a air ow gen­erated by the fan on main motor (Battery version) or
dynamotor (Petrol version).

The lter located between the vacuum system and the
hopper, retain dirt which is then discharged into the

hopper itself.
The operation of the system depends on the activation
of the machine and the main broom.
The vacuum system consists of a fan installed on the
main motor / dynamotor which is powered by the re­lay (K0) (see Electrical and Control System chapter).

Dust Control System 27Service Manual – SW900

VERSION WITH ELECTRICAL FILTER SHAKER

The electric lter shaker system consists of a motor

(M1) which is powered by the relay (K1) and protected
by the fuse (F1) (see Electrical and Control System
chapter).

VERSION WITH MANUAL FILTER SHAKER

By operating on the lever on the right side of the ma­chine, a rake acts mechanically on the lter ns al­lowing dirt trapped in the folds of the same to fall by
gravity into the hopper.
