Suction Inlet And Skirt Height And Operation Check - Nilfisk RS 501 Instrucciones De Uso

SUCTION INLET AND SKIRT HEIGHT AND OPERATION CHECK

Preliminary operations
Engage the parking brake (7, Fig. E).
1.
2. Lift the suction inlet (10, Fig. G) according to the procedure shown in the relevant paragraph.
Turn off the engine, by turning the ignition key (17, Fig. D) counterclockwise, to the end of stroke, then remove it.
3.
Suction inlet wheel check
Check that the three wheels (1, Fig. Z) of the suction inlet are in good conditions and turn freely (they must not be bent/
4.
misshapen because of bumps or excessive pressure, etc.). Check also that the rubber thickness (2) is not lower than some
millimeter.
If necessary replace the wheels (1) (see the procedure in the Service Manual).
Skid plate check
Check that the main sliding panel (3, Fig. Z), the front skid plates (4) and (5), and the rear skid plate (6) are in good conditions
5.
and that their thickness (7) is not lower than 0.2 in (5 mm), otherwise replace them (see the procedure in the Service Manual).
It is important to replace the skid plates (3), (4), (5) and (6) when they are not completely worn, to avoid damaging the relevant
mounting screws and making them difficult to remove.
Replace the skid plates (3), (4), (5) and (6) as a unit, to avoid steps in the union areas (8), caused by different levels of wear.
Suction inlet skirt and wheel adjustment check
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
6.
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.
Turn off the engine, by turning the ignition key (17, Fig. D) counterclockwise, to the end of stroke, then remove it.
8.
Check that the distance (12, Fig. Z) of the skirt from the ground is not greater than 0.4 in (1 cm). Greater distances can affect
9.
the suction inlet operation.
If necessary replace the skirt (9) (see the procedure in the Service Manual).
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.
10.
Otherwise the wheels (1) must be replaced to avoid an excessive wear of the skid plates (see the procedure in the Service
Manual).
Start the machine according to the procedure shown in the relevant paragraph, then lift the skirt (9, Fig. Z) and check that it lifts
11.
freely. Check that it lifts also when a force of 6.6÷11 lb (3÷5 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.
