Side Broom Position Check And Adjustment - Nilfisk Advance RS 501 Manuel D'utilisation

Suction inlet skirt and wheel adjustment check
6. Check that the skirt (9, Fig. Z) is integral and that it does
not have excessive tears (10) or lacerations (11), which
can affect the suction inlet operation.
If necessary replace the skirt (9) (see the procedure in
the Service Manual).
7. Drive the machine on a level ground and lower the
suction inlet (10, Fig. G) according to the procedure
shown in the relevant paragraph.
8. Turn off the engine, by turning the ignition key (17, Fig.
D) counterclockwise, to the end of stroke, then remove
it.
9. Check that the distance (12, Fig. Z) of the skirt from the
ground is not bigger than 1 cm. Greater distances can
affect the suction inlet operation.
If necessary replace the skirt (9) (see the procedure in
the Service Manual).
10. Also check that, when the wheels (1, Fig. Z) contact the
ground, the sliding panels (3), (4), (5) and (6) do not
touch the ground. Otherwise the wheels (1) must be
replaced to avoid an excessive wear of the sliding
panels (see the procedure in the Service Manual).
11. Start the machine according to the procedure shown in
the relevant paragraph, then lift the skirt (9, Fig. Z) and
check that it lifts freely. Check that it lifts also when a
force of some kg is applied (simulating to move bottles
or other heavy objects that must then be collected). If
necessary, adjust the opening force of the skirt (9)
according to the following procedure:
– Turn off the machine.
– Remove the screws and the right panel (20, Fig. E)
in the cab.
– Loosen the control valve locknut (1, Fig. Y) and
turn the screw (2) as necessary, reminding that:
– The opening force decreases by loosening the
screw;
– The opening force increases by tightening the
screw.
– When the adjustment is completed, tighten the
locknut (1).
– Install the right panel (20, Fig. E) in the cab and
tighten the screws.
12. Assemble the components in the reverse order of
disassembly.

USER MANUAL
NOTE
Brooms of various hardness are available. This
procedure is applicable to all types of brooms.
Check the side brooms for proper height and tilting,
according to the following procedure:
– Drive the machine on a level ground.
– While keeping the machine stationary, fully lower
the side brooms and allow them to rotate for a few
seconds.
– Stop and lift the side brooms, then move the
machine.
– Check that the size and orientation of the prints left
by the side brooms are as follows:
– The right side broom must touch the ground along
a circle arc ranging from "11 o'clock" position to "4
o'clock" position (1, Fig. AB).
– The left side broom must touch the ground along a
circle arc ranging from "8 o'clock" position to "1
o'clock" position (2, Fig. AB).
Adjust the broom height when the prints are out of
specification, according to the following procedure.
Engage the parking brake with the lever (7, Fig. E).
Turn the ignition key (17, Fig. D) counterclockwise, to
the end of stroke, then remove it.
On both sides of the machine, operate on the tensioning
self-locking nut (1, Fig. AA) of the spring (2) and
consider the following:
– To lower the broom, the nut (1) must be
unscrewed;
– To lift the broom, the nut (1) must be screwed.
Perform step 1 again.
On both sides of the machine, loosen the screws (5 and
6, Fig. AA), then adjust the forward tilting angle (3).
When the adjustment is completed, tighten the screws
(5) and (6).
Perform step 1 again.
