Vacuum fan

FIG 20
Electric sweeper
1
The vacuum fan 1 (fig. 20) generates the suction which removes the dust lifted by the brushes. The fan is driven by the motor 2.
!
WARNING! Shut off the suction with lever 1, fig. 3 when driving over wet floors.
When driving the sweeper from one place to another without sweeping, proceed as follows:
– For the "electric sweeper" stop the rotation of brushes and vacuum fan motor by the switch 5 (fig. 3);
– For the "petrol sweeper" lift the brushes by the levers 2 – 6 fig. 3 to stop its rotation.
At the end of fan drive shaft there are pulleys which drive the following belts:
1. Pump drive belt. (petrol sweeper).
2. Primary brush drive belt.
Every 100 – 150 hours work, check the tension and the wear of the primary brush drive belts.
See the relevant section for details on how to replace this belt.

Dust flaps

FIG 21
2
The dust flaps prevent the dust raised by the brushes from blowing out from under
the motor-sweeper. They must therefore be kept in peak condition and replaced if
they become worn or damaged.
Replacing the flaps
1. Remove the fixing bolts and remove the worn or damaged flap.
2. Fit a new flap 1-2-3-4 (fig. 21) and secure it in position with the same bolts. The
side and rear flaps should ride at about 3 – 4 mm above floor level.
