Precautions and safety regulations when using the vacuum cleaner
Before start-up
Inspect power cord regularly to detect signs of damage, e.g. cracks or ageing.
DANGER
If the supply cord is damaged, it must be replaced by Nilfisk, a Nilfisk- service agent or similarly qualified persons in order to avoid a hazard.
Use only the type of power cord specified in the operating manual.
Do not damage the power cord (e.g. by moving over it or pulling or crushing it).
Inspect the vacuum cleaners to ensure that they are in proper condition.
Disconnect the power cord by pulling the plug only (do not pull or tug the power cord).
Make sure to install the vacuum cleaners with IP68 plug and socket properly, i.e; inscrew the cap, connect the plug into the socket, and tighten the locking ring. Please repeat in the reverse order when disconnecting Never use the cleaner if the filter sieve is damaged.
Picking up liquids
If foam develops or liquid emerges, stop work immediately and empty the dirt tank.
Before picking up liquids, check the function of the water level limiter (hose for automatic level control).
You can find information on handling liquids in Chapter 5.
Electrical components
Check the rated voltage of the vacuum cleaner before connecting it to the mains supply system. Ensure that the voltage shown on the rating plate corresponds to the voltage of the local mains power supply.
If you are using an extension cord, use only those specified by the manufacturer or higher quality ones (see section 9.4 „Technical data“).
It is recommended that the vacuum cleaner should be connected via a residual current circuit breaker.
This stops the supply of electricity if the leakage current to earth exceeds 30 mA for 30 ms or it has an earth tester circuit.
When using an extension lead, check the minimum cross-sections of the cable:

Cable length m|

Cross section

---|---
<16 A| <25 A
up to 20 m| ø1.5mm²| ø2.5mm²
20 to 50 m| ø2.5mm²| ø4.0mm²

Arrange the electrical parts (sockets, plugs and couplings) and lay down the extension lead so that the protection class is maintained.
Never spray water on to the upper section of the vacuum cleaner. Danger for persons, risk or short-circuiting.
Observe the latest edition of the IEC regulations.
Submerged pump socket
The submerged pump IP68 socket is designed as the mains supply to the internal pump.
Make sure to switch off the vacuum cleaner before plugging in the pump.
Maintenance, cleaning and repair
Only carry out maintenance work described in the operating instructions.
Always pull out the mains plug before cleaning and maintenance of the vacuum cleaner.
Accessories and spare parts
Use only the brushes supplied with the vacuum cleaner or specified in the operating manual.
The use of other brushes can adversely affect safety.
Use only original Nilfisk accessories and spare parts (see section 9.5).
The use of other parts can adversely affect safety.

Before starting

3.1 Assembling the cleaner

Upon delivery some of the accessories are lying in the packaging and must be removed before the cleaner is used for the first time.

1. Remove all the accessories 1)  from the packaging and assemble the cleaner.

Operation

4.1 Connections
4.1.1 Connecting the suction hose

1. Insert the suction hose on the tank.
2. Connect the water drainage hose to the coupling on the tank.

4.1.2 Electrical connection
The operating voltage shown on the rating plate must correspond to the voltage of the mains power supply.

1. Ensure that the cleaner is switched off.
2. Insert the power cord into a properly installed and fused socket with earthing contact.
3. Activate the personal safety switch 1)

4.1.3 Connect the submerged pump
The IP68 socket on the operating panel is to connect the in-built submerged pump only.

1. Insert the plug of the submerged pump into the IP68 socket on the operating panel and tighten the locking ring.

4.2 Switching on the cleaner
4.2.1 Switch position „I“
The submerged pump cannot be operated in switch position „I“.
The suction motor is switched off when the maximum level has been reached. Switch off the cleaner and empty the tank.

1. Turn the switch to position „I“.
   The suction motor starts.

4.2.2 Switch position „auto“
Before switching the switch to position „auto“, ensure that the submerged pump is connected.

If the tank is empty, the suction motor runs alone. When the tank starts filling with water, the submerged pump switches on. When the tank is almost full, suction is reduced to prevent the tank from being over filled. The suction motor is switched off when the maximum level has been reached. As soon as the water level has been significantly lowered by the submerged pump, the suction motor is switched on again. When the tank is completely emptied, there is a delay before the submerged pump is switched off.

1. Turn the switch to position „auto“.
   The fully automatic tank emptying procedure is activated.

4.2.3 Switch position „ “
The switch position „ “ is a touch position (it resets automatically). If it is pressed once, the submerged pump works for 30 seconds.
At the same time the submerged pump is protected from running dry.

1. Turn the switch to position „ “.
   The tank can be emptied with this function.

4.2.4 Setting suction power

The motor speed and the suction power can be varied with the suction power control. This allows precise adaptation of the suction power for different cleaning tasks.
4.2.5 Temperature monitoring
A sensor measures the exhaust air temperature and reduces the suction power as soon as the max. permissible temperature has been exceeded. If the ex- haust air temperature is too high, the suction motor is switched off. Switch off the cleaner and allow it to cool.

Applications and techniques

5.1 Techniques
If used correctly, additional accessories, suction nozzles and suction hoses can enhance the cleaning action and reduce the cleaning effort.
Effective cleaning is achieved if you follow just a few guidelines in combination with your own practical experience in special fi ends.
Here are some basic tips.
5.1.1 Picking up liquids
CAUTION!
Do not pick up fl ammable liquids.
Before picking up liquids, check the function of the water level limiter (hose for automatic level control) (see Section 7.2.2 „Cleaning and replacing the filter sieve“, step 6.).
Do not use the cleaner as a water pump. Do not insert the suction pipe or suction noz-zle completely in the water but always draw in a small amount of air in order to protect the turbine from overheating.
If foam appears, stop work immediately and empty the tank.
To reduce the amount of foam, use foam killer Nilfi sk Foam Stop (see section 9.5 “Accessories” for order number).

After finishing work
