Frequently Asked Questions - SW5500 NILFISK

How to start the Nilfisk SW5500 sweeper?

Sit on the driver's seat (the safety microswitch is activated). Turn the ignition key to position « I », wait for the work screen to display, then turn the key to position « II » to start the engine. Release the key after starting. Disengage the parking brake and press the accelerator pedal to move forward.

How to empty the waste container?

Place the machine on a level surface and engage the parking brake. Raise the brushes using the One-Touch button. Simultaneously press the confirmation button (66) and the lift button (61) to raise the container. Move the machine over the collection area, then press the confirmation button and the dumping button (62) to tilt the container. After emptying, use buttons (63) and (61) to return the container to the working position.

What type of fuel to use for the Diesel and LPG versions?

For the Diesel version, use standard diesel fuel. For the LPG version, use liquefied petroleum gas (LPG) in bottles. Never use old or contaminated fuel.

How to clean the dust filter?

The filter can be cleaned using three methods: Method A: vacuum the dust and gently tap the filter on the dirty side. Method B: blow compressed air (max 6 bar) from the clean side. Method C (polyester filter only): immerse in hot water for 15 minutes, rinse at low pressure (max 2.5 bar) and allow to dry completely before reassembly. Always wear safety glasses and a protective mask.

What are the main safety features of the SW5500?

The machine is equipped with an emergency stop button (stops all functions), a seat microswitch (prevents operation without operator), an anti-skid system that reduces speed when cornering, a tilt sensor (alerts if the container is lifted on a slope), a container position sensor (reduces speed and stops brushes if the container is raised), and a hydraulic safety valve on the container.

What is the recommended maintenance frequency for the engine?

The maintenance schedule includes: check engine oil level before each use or every 10 hours, oil change every 200 hours or 6 months (after the first 20 hours of break-in), replacement of paper air filter every year, spark plug check (LPG version) every 200 hours, and more extensive servicing by an authorized dealer every 500 hours.

How to adjust the height of the main brush?

Move the machine to a flat surface, engage the parking brake. Lower the main brush using the One-Touch button and hold it for 3 seconds to make it rotate. After 30 seconds, raise the brush. Check the mark left on the ground: it should be 2 to 4 cm wide along the entire length. If not, turn the adjustment knob (9): counterclockwise to increase the mark, clockwise to reduce it.

What to do if the engine does not start?

First check that the emergency button is not activated (turn it to deactivate). Check the fuel level: for Diesel, open the tap; for LPG, open the bottle valve. Ensure the batteries are charged. If icon (71-R) displays, the engine oil level is too low: top it up. If icon (71-Q) appears, the engine is overheating: let it cool down.

What is the water tank capacity for the DustGuard system (optional)?

The water tank of the DustGuard™ dust suppression system has a capacity of 32 liters. It must be filled with clean cold water (<20°C), and emptied regularly to prevent bacterial growth.

How to replace the main brush?

Place the machine on a flat surface, engage the parking brake and turn off the ignition. Remove the left access door (14) by turning the fasteners. Pull the handle (C) to release the closure support, then open the side panel. Remove the worn brush. Clean the drive hub. Install the new brush by orienting the bristles as shown (figure H) and engaging the hexagonal drive on the hub. Close the support and refit the access door. After replacement, adjust the brush height.
