Working - Tennant T290 Manual De Instrucciones

• make sure the squeegee (fig. 2, ref. 6) is firmly attached and connected to the suction
hose (fig. 6, ref. 4). Make sure the back blade is not worn.
If you are using the machine for the first time, we recommend trying it out on a
large obstacle-free surface first to acquire the necessary familiarity.
Always empty the dirty water tank before filling the detergent tank again.
For effective cleaning and to extend the working life of the machine, follow a few simple
rules:
• prepare the work area by removing all possible obstacles;
• begin working from the furthermost point to avoid walking on the area you have just
cleaned;
• choose the straightest possible working routes;
• divide large floors into parallel rectangular sections.
If necessary, finish off by passing a mop or rag rapidly over parts inaccessible to the
scrubber drier.

Working

After setting up the machine, proceed as follows:
• lower the squeegee by means of the corresponding lever (fig. 5, ref. 8);
• press the brush button (fig. 5, ref. 3) (LED on), the suction motor starts up
automatically;
• press the suction button (fig. 5, ref. 2) if you want to disable detergent suction;
• press the brush/drive lever (fig. 5, ref. 7);
• Models with mechanical drive: When the brush motor is enabled and the drive lever is
pulled, the motor which turns the brush and moves the machine starts up. A special
mechanical drive device uses the friction between the brush and floor to generate a
forward movement. When the mechanical drive lever is released, the brush motor
shuts down and the machine stops.
If the machine pulls to one side, restore a straight course by using the direction
regulation knob (fig. 5, ref. 10). If the machine pulls to the right, turn the knob clockwise
and vice versa.
• Models with electric drive: to move forwards or backwards, see paragraph 6.3.
periodically check that the detergent is reaching the brushes and refill when it runs out.
When there is no longer sufficient water in the detergent tank, the level indicator lights up
(fig. 5, ref. 5). Stop and fill the tank; when working, check cleaning quality and if necessary
adjust the flow of detergent by pressing the button (fig. 5, ref. 18); the amount of liquid
delivered is indicated by the LEDs (fig. 5, ref. 20).
Empty the dirty water tank each time you fill the detergent tank.
Never leave the suction motor on and detergent tap open when parked.
• when the dirty water drum is full, the level indicator comes on (fig. 5, ref. 4) and after a
few seconds the suction motor shuts off. You must stop working and empty the tank.
• if the warning LED (fig. 5, ref. 1) starts flashing, it means that the batteries are almost
flat. After a few seconds the brushes shut down to prevent excessive discharge of the
batteries. Charge the batteries.
At the end of work:
• release the brush/drive lever (fig. 5, ref. 7) located under the handgrip. This turns the
brush/drive motor off and the machine stops;
• stop the brush by pressing the button (fig. 5, ref. 3);
• lift the lever (fig. 5, ref. 8) to raise the squeegee from the floor to prevent the continuous
pressure from warping the blades;
• remove the brushes (or drive disks) to prevent them from warping permanently;
