Frequently Asked Questions - SW4000 NILFISK

What type of fuel to use for the Nilfisk SW4000 engine?

Use unleaded petrol with an octane rating of at least 91 for the petrol version. For the LPG version, use liquefied petroleum gas (LPG) with a suitable cylinder.

How to empty the waste container?

Place the machine on a level surface, raise the brooms, then press simultaneously the confirmation switch (66) and the lifting switch (79) to raise the container. Use the lever (9) to tilt the container and empty the waste. Then lower the container by repeating the reverse operation.

How to adjust the central broom height?

Let the central broom run for one minute on a flat surface, then measure the width of the trace left (should be 2 to 4 cm). Turn the handle (62): counterclockwise to increase pressure, clockwise to reduce it. Check the trace again.

What to do if the engine does not start?

First check the engine oil level (too low = automatic stop). Make sure the petrol tap is open (petrol version) or the LPG valve is open (LPG version). Check that the cold start lever is in the correct position. If the spark plug does not produce a spark, clean or replace it. Also check fuses F3 and F0.

How to clean the dust filter?

Three methods are possible: Method A: vacuum the dust and tap lightly; Method B: blow compressed air at 6 bar max from the clean side; Method C (for standard paper filter): immerse in hot water for 15 min, rinse at 2.5 bar max, dry completely before reassembling. Always wear goggles and a mask.

What is the emergency stop procedure?

In case of emergency, press the emergency pushbutton (77) located to the left of the operator. This immediately stops all machine functions. To deactivate it after use, turn it in the direction of the arrow indicated on the button.

How to replace the right side broom?

Place the machine on a flat surface, parking brake engaged, key in position '0'. Raise the side broom with lever (64). Release the pivot latch (A), remove the pivot, then remove the broom (B) and the protection ring (C). Install the new broom on the hub (D) with the ring, insert the pivot and engage the latch. Then adjust the height according to the procedure.

How to check the engine oil level?

Ensure the machine is stopped on a flat surface. Open the engine hood (18), remove the right side panel (45). Remove the oil dipstick (A), clean it, insert it without screwing, then remove it. The level should be between the lower (C) and upper (D) marks. If necessary, add the recommended oil (see engine manual). Do not overfill.

What are the main safety devices of the SW4000?

The machine is equipped with: an emergency pushbutton (77) for immediate stop, a seat microswitch that prevents any movement if the operator is not seated, a container position sensor that reduces speed and stops suction and brooms when the container is raised, and a hydraulic safety valve that prevents accidental container fall.

How to activate the DustGuard™ dust control system?

The dust control system (optional) is activated via the switch (80) on the dashboard. Ensure the water tank (24) is filled with clean water (do not fill completely). The system will start automatically when the side brooms are lowered and the machine is moving. Use cold water (< 20 °C) to prevent bacterial growth.

B C A RUN START LPG START

P100592

Figure 1

1. After the ignition, let the engine run for a few seconds, when the engine is warm move the choke lever in position (A, Fig. 1).
2. Disengage the parking brake.
3. Drive the machine to the working area, by keeping the hands on the steering wheel (1) and pressing the pedal (5). The drive speed can be adjusted from zero to maximum speed by increasing the pressure on the pedal.
4. The forward/reverse direction is selected with the relevant switch (68) on the dashboard. When the reverse gear is selected, the relevant buzzer turns on.
5. Lower the main broom with the lever (63).
6. Lower the side brooms with the lever (64).

NOTE

When the brooms are lowered, the brooms, the vacuum system and the dust guard system (optional - if turned on with the switch (80)) automatically activates only when the machine is moving.

1. Start sweeping by driving the machine with the hands on the steering wheel (1) and by pressing the drive pedal (5).

NOTE

The brooms (14, 15 and 17) can be lowered and lifted even when the machine is moving.

The brooms do not turn when they are lifted or when the machine is stationary.

When the machine is stationary, the vacuum system and dust guard system (optional), turn off automatically.

WARNING!

When steering, avoid abrupt direction changes, pay careful attention and drive the machine at slow speed, especially when the hopper is full or when operating on inclines.

Drive the machine slowly on inclines. Use the brake pedal (6) to control machine speed while descending inclines.

Do not turn the machine on an incline; drive straight up or down.

Stopping the machine

1. To stop the machine, release the drive pedal (5).

To stop the machine quickly, also press the service brake pedal (6).

WARNING!

Frequent and extended use of the service brake (6), especially on slopes, can cause a rapid wear of the pads.

Keep the braking system in maximum efficiency (see paragraphs Brake Cable Adjustment and Scheduled Maintenance Table in Maintenance chapter).

1. In case of emergency, press the emergency push-button (77) to immediately stop the machine.

To deactivate the emergency push-button (77), turn it clockwise.

1. Turn the ignition key (61) to "0" and remove it.

DISPLAY

The display (69) shows the machine working hours; the time counted is the one during which the main broom is moving.

NOTE

When the working hour count exceeds 999, hours are then displayed in thousands with two decimal digits (for example 1.23 = 1,230 hours).

By pressing the push-button (70) it is possible to shortly display the battery voltage in Volts, with one decimal digit.

Displayed codes

1. If the display (69) repeatedly displays "LOU" code, it means that the batteries could be damaged: therefore, it is necessary to reduce the intensity of work, for example by reducing the ground pressure of the broom, or by avoiding running extensively on slopes.
2. If the display (69) repeatedly displays "HIU" code, it means that the battery charge is excessive: this may happen, for example, if the machine is kept for too long with the engine running. In this case, stop the engine when the machine is stationary.
   If these problems persist, maybe it is necessary to calibrate the engine rpm. For this operation, contact an authorised Nilfisk Service Center.

CAUTION!

Working for a long time with the above codes displayed can reduce the working life of the batteries.

MACHINE OPERATION

1. Drive the machine to the work area as shown in the previous paragraph.
2. Lower the main broom with the lever (63), and the side brooms with the lever (64).
3. If equipped, turn on the dust guard system with the switch (80).
4. Drive the machine straight forward at a quick walking speed. Drive the machine slower when sweeping large amounts of dust or debris or when safe operation dictates slower speeds. Overlap passes 10 cm.
5. To collect light and bulky waste materials, lift the front skirt by pressing the pedal (8); take into consideration that the machine vacuum capability is reduced when the front skirt is lifted.

WARNING!

When operating on wet floors, it is essential to turn off the vacuum system by pressing the switch (65) to prevent the dust filter from being damaged.

1. For machine proper operation, the dust filter must be as clean as possible. For cleaning it while sweeping, turn on the filter shaker by pressing the lower side of the switch (65). While working, repeat the procedure every 10 minutes on average (depending on the dustiness of the area to be cleaned).

NOTE

This procedure can also be performed when the machine is moving.

CAUTION!

When the dust filter is clogged and/or the hopper is full, the machine cannot collect dust and debris any more.

1. The hopper (11) should be dumped after each working period and whenever it is full (see the procedure in the next paragraph).

CAUTION!

The engine is equipped with a warning system to prevent damages to the engine itself in case the oil quantity in the carter is insufficient. Before the oil level goes below the safety limit, the warning system automatically stops the engine.

CAUTION!

If the main broom motor overload warning light (75) flashes repeatedly while sweeping, there may be debris that slows down the broom (for checking this, see the procedure in Main Broom Replacement paragraph, under Maintenance chapter), or the pressure on the ground may be excessive (see the procedure in Main Broom Height Check and Adjustment paragraph, under Maintenance chapter). If the overload persists, the brooms may stop. In this case, stop and restart the machine to restore the broom operation.

HOPPER DUMPING

WARNING!

The hopper (11) must be emptied on level grounds only. Do not lift the hopper when the machine is on a slope.

WARNING!

When lifting and dumping the hopper (11), make sure that there are no people around the machine, especially near the hopper.

NOTE

When the hopper (11) is lifted, the vacuum system turns off automatically and the machine maximum speed is reduced for safety reasons.

To empty the hopper, move the machine close to the dustbin and proceed as follows.

1. Lift the side and main brooms.
2. Press the enabling switch (66) while pressing the hopper lifting switch (79) to lift the hopper (A, Fig. 2) up to the desired position.
3. Drive the machine to the disposal area and engage the parking brake.
4. Dump the hopper (B) with the lever (9) to discharge all dust and debris collected (C).

NOTE

If necessary, manually engage the hopper in position (A) with the returning handle (E) when the hoisting system is lifted and the hopper is disengaged (B).

CAUTION!

The hopper (A) can be dumped only when lifted at a minimum height of 35 cm approximately.

The maximum dumping height is approx. 150 cm.

1. Lower the hopper by pressing both the enabling switch (66) and the switch (79).

NOTE

To ensure that the hopper (11) is fully retracted, check that the warning light (74) is off.
