Frequently Asked Questions - FB2170 NILFISK

How to start the vacuum?

First check that the machine is plugged into a 400 V socket with grounding. Make sure the main switch is set to '0'. To start, turn the start switch to 'I'. If the machine does not suck, the motor rotation direction may be reversed: unplug the plug and use the phase reverser.

How to clean the primary filter?

When the vacuum gauge needle enters the red zone, stop the machine. Use the manual shaking lever (turn it 5 times clockwise then counterclockwise) or press the electric shaking button for 10-15 seconds. Wait for the dust to settle before restarting. If the light remains red, replace the filter.

What to do if the vacuum does not suck?

Check that the plug and cable are not damaged. Check the power supply. If the motor runs but does not suck, the primary filter is probably clogged or the hose is blocked. Clean or replace the filter. If the motor speed increases abnormally, it is often a sign of clogging.

How to empty the dust tank?

Turn off the machine and unplug it. Unhook the tank using the lever, remove it and empty it. Clean the inside with water if aggressive substances have been vacuumed. Check the condition of the sealing gasket before putting the tank back in place. Let the machine run for 60 seconds after cleaning before turning it off.

Can I vacuum liquids with this vacuum?

Yes, provided the machine is equipped with the mechanical liquid stop device (float). Before vacuuming liquids, check that the stop is working properly. If foam forms, stop the machine immediately and empty the tank. After vacuuming liquids, the filter is wet; dry it or replace it before vacuuming dry substances.

How to replace the Longopac® dust bag?

Turn off the machine and unplug it. Prepare the bag holder by inserting the Longopac® into the groove. Slide the inner end by 250 mm, tighten the strap. Close the outer end with a clamp. Place the bag holder under the hopper and lock it. Pull the closed bag down and fix the inner end on the hopper gasket.

What are the important safety instructions?

Never use the machine without a filter. Do not vacuum hot materials, combustible gases or flammable liquids. Do not use outdoors in rain. Always unplug before any intervention. Wear PPE (gloves, P3 mask) for hazardous dust. Respect filtration classes L, M, H.

What to do in case of dust leakage?

Stop the machine immediately and unplug it. Check if the filter is torn or incorrectly installed. Replace the filter with a model of the same category. Also check the tank gasket. If the leak persists, contact customer service.

How to maintain the HEPA absolute filter?

For the absolute filter in suction, replace it by unscrewing the hose clamp, removing the cap, then removing the filter. Place the old filter in an airtight plastic bag and dispose of it according to applicable laws. For the absolute filter in blowing, unscrew the four nuts of the housing, remove the filter, replace it and retighten. Note: do not reuse an H filter after disassembly.

What are the dimensions and weight of the vacuum?

Typical dimensions (TxxPLUS L L50 model) are 600 mm width, 1350 mm depth and 1300 mm height. Weight is about 175 kg. For other versions, dimensions may vary (up to 1800 mm height). Storage conditions: temperature -10°C to +40°C, humidity ≤85%.
