TECHNICAL SPECIFICATIONS

PARTS IDENTIFICATION

Method of operation

The Powr-Flite PW050-W26-U is a machine designed to sweep and clean waste from hard floors and carpets. The side brush (Fig. 4/1) sweeps the dirt from corners to a position in front of the rotary brush (Fig. 4/2). The rotary brush sweeps the larger particle dirt overhead into the debris container (Fig. 4/3). The finer dust picked up is drawn up by the suction turbine, fed into the filter system (Fig. 4/4), and filtered out. Only dust-free air is fed back into the ambient air. The machine is equipped with maintenance-free batteries (Fig. 4/5), a specially adapted, fully automatic battery charger (Fig. 4/6), and a total discharge signal transducer to protect it against total discharge.

Operating and indicator elements

1. Control lamp for rotary brush drive, side brush drive, and suction turbine
2. ON/OFF button for rotary brush drive, side brush drive, and suction turbine
3. Control lamp for side brush drive
4. ON/OFF button for side brush drive
5. Control lamp for battery charger operation
6. Charge control indicator
7. Drive bar

ON/OFF button for rotary brush, side brush, and suction turbine (Fig. 5/1).

The button activates the rotary brush drive, side brush drive, and suction turbine so they are ready to operate. The side brush drive can be switched off separately. The suction turbine cannot be switched off separately, which prevents the dust vacuum from being activated by accident.

Control lamp for rotary brush drive, side brush drive, and suction turbine (Fig. 5/2).

The green control lamp indicates that the rotary brush drive and suction turbine are ready to operate. If the rotary brush or suction turbine is overloaded, a safety shutdown is triggered and the control lamp flashes.

ON/OFF button for side brush drive (Fig. 5/3).

The button can be used to switch off the side brush drive independently of the rotary brush drive and to activate it for use again.

Control lamp for side brush drive (Fig. 5/4).

The green control lamp indicates that the side brush drive is ready to operate. If the side brush is overloaded, a safety shutdown is triggered, and the control lamp flashes.

Control lamp for battery charger operation (Fig. 5/5).

This control lamp indicates that the batteries are being charged.

Charge control indicator (Fig. 5/6).

During the charging process, the machine’s electronics system controls ensure the machine is not switched on inadvertently and indicate the charge status. The battery charge status is indicated by 4 green and 1 red LED.

The battery voltage is depicted in 5 levels:

• > 25.1 V = all green LEDs on
• > 24.5 V = bottom 3 green LEDs on
• > 23.9 V = bottom 2 green LEDs on
• > 22.7 V = bottom green LED on
• > < 22.7 V = red battery LED flashes

Drive bar (Fig. 5/7).

The drive bar switches all the drives that are ready to operate on or off. The drive bar serves to prevent damage. If the drive bar is released during operation, all the drives are switched off.

3.2.2 Operating elements on the machine

Knurled screws for handle (Fig. 6/1).

The two knurled screws enable the handle to be adjusted to a comfortable height for the user.

Shaking device lever (Fig. 6/2).

In order to clean the filter in the dust vacuum, switch the shaking device lever several times quickly to the left and right.

Debris container locks (Fig. 6/3).

Instruction

Instructions to operators are required before putting the machine into service. Only technicians from your local, authorized Tornado dealer are allowed to provide initial instruction on how to use the machine.

Initial battery charge

Prior to starting up

Carry out the following checks before starting the machine:

1. Check the charge status of the batteries.
2. Check the levels of wear on the rotary brush and side brush.
3. Check the fill level of the debris container.

Operation

Please read the Safety Information in Chapter 1. Before switching the machine on, ensure that the drive bar (Fig. 3/3) on the handle has not been actuated.

1. Switch the machine on using the (Fig. 3/1) button; the rotary brush drive, dust vacuum, and side brush drive are ready to operate.
2. Lower the side brush to its working position using the lever (Fig. 3/4). When working without the side brush, do not lower the side brush and press the button (Fig. 3/2) for the side brush once. The green control lamp goes out.
3. Actuate the drive bar (Fig. 3/3) on the handle; the machine starts to work. Start work immediately after actuating the drive bar; imprints could be produced on the floor. Release the drive bar when driving over thresholds.

Stopping the machine

When the drive bar is released, the rotary brush drive, dust vacuum, and side brush drive switch off automatically.

After completing work

1. Drive to an appropriate maintenance area.
2. Stop the machine. Raise the side brush to its idle position and switch the machine off.
3. Actuate the filter shaker.
4. Empty the debris container.

MAINTENANCE

Charging the batteries

The charge control indicator (Fig. 7/2) indicates the charge status of the batteries during operation. The batteries must be charged immediately when the red LED lights up. The batteries (Fig. 7/7) are charged using the integrated battery charger (Fig. 7/3). The charger is connected by means of the power cable (Fig. 7/4). While the battery is being charged, the battery indicator on the charger (Fig. 7/1) lights up.

Before starting the machine up for the first time, the batteries to be used must be fully charged properly by implementing the initial battery charge routine. Tornado assumes no liability for damage to the battery caused by a fault when the battery is charged for the first time.

Total discharge signal transducer (TSG)

The machine is equipped with a total discharge signal transducer to protect the batteries against total discharge. The total discharge signal transducer is integrated in the electronics.

Servicing the driving batteries: Never leave discharged batteries lying around; recharge them immediately!
