Environmental protection
Raw material recovery instead of waste disposal!
To avoid transport damage, the unit must be delivered in sturdy packaging.
Packaging as well as the unit and accessories are made of recyclable materials.
The plastic parts of the unit are labelled according to the material. This enables
environmentally friendly, sorted disposal via the collection facilities offered.
Only for EU countries
Do not throw power tools in the household waste! According to the European
Directive 2012/19/EU on waste electrical and electronic equipment and its
implementation in national law, used power tools must be collected separately and
recycled in an environmentally sound manner.
Grounding
The hoover must be earthed. Should a malfunction or failure occur, earthing
provides a path of least resistance for electric current to reduce the risk of electric
shock. The hoover is equipped with a cord, with an appliance grounding conductor
and grounding plug. The plug must be plugged into a suitable outlet that is properly
installed and grounded in accordance with all local codes and ordinances.
Commissioning
Put the machine in working position, secure the vacuum cleaner by locking the
steering wheel brakes if necessary.
Before fitting the suction hose with floor nozzle or other optional accessories, check
that all parts are in good condition and have no damage.
8

Connect the floor brush to the 2 straight
pipes. Then connect the hose with the
hose collar to the pipe. Then the hose
can be connected to the adapter via the
hose collar. Finally, the hose can be
connected to the dust extraction
connection on the appliance.
Function
The NTS-38/HEPA is suitable for the suction and separation of dry, non-flammable
dust with an explosion limit value of 0.1mg/m³.
The wet-dry vacuum cleaner is started by the switch.
1. Switch for controlling the engine speed
2. Socket (power connection for power tools, max.
1200W)
3. On/Off switch
ON Switch on
0Switch off
Auto The vacuum starts by the connected
power tool, after stopping the power tool
the vacuum stops with a delay of 7
seconds.
There is an airflow adjustment ring on the handle of
the appliance. By turning the adjustment ring, the
suction power can be set for different needs when
vacuuming.
Note:
When using the power socket on the unit, make sure
that the plug and socket match.

Note:
Switch off the appliance until the motor has come to a complete stop.
Always unplug the appliance when working on the appliance or when the appliance
is not working properly.
After starting the wet-dry vacuum cleaner, the dust-laden air is sucked in at high
speed via the suction hose through the inlet valve. The air is slowed down by the
cyclone and the coarse dust particles are separated partly by centrifugal force and
partly by gravity. The air and dust particles then pass through the filter system
where separation takes place. The machine is designed to perform filter cleaning in
the form of automatic cleaning. The separated dust collects in the cyclone until the
machine is switched off, then it falls through the lower opening into the dust
collection tank.
The filter cleaning process is not complete until it is clear that the dust inside the
tank has fallen into the collection tank. In some extreme cases, the dust's stickiness
must be broken manually. This can be done by tapping the dust through the bag or
by carefully tapping the tank, e.g. with a rubber mallet.
Innovative car cleaning
When the hoover is switched on, both filters are cleaned automatically and
alternately. See diagram:
