The parking brake acts as soon as the appliance comes to a standstill.

Before Startup

Open/ close device hood
DANGER
Danger of crushing while closing the machine cover. Hence, lower the machine cover slowly.
Prior to commissioning, maintenance or adjustment tasks, the appliance cover must be opened.

• Grab the front of the appliance cover and fold it back together with the seat.
• A retaining band keeps the appliance cover in the rear position.

Unloading tips
Danger
Risk of injury, risk of damage!
Observe the weight of the appliance when you load it!
Do not use a forklift truck to unload the machine as this may damage it.
Note

Press the emergency-stop button to immediately deactivate all functions and turn the key switch to the “0” position.

• If upgrade kits are installed, the weight is respectively higher.

  • Use a suitable ramp or a crane to load the appliance!

  • If the machine is delivered on a pallet, you must create an unloading ramp using the boards provided. To unload the machine, proceed as follows:

  • Cut plastic packing belt and remove foil.

  • Remove the elastic tape fasteners at the stop points. Four indicated floor boards of the pallet are fastened with screws. Unscrew these boards.

  • Place the boards on the edge of the pallet. Place the boards in such a way that they lie in front of the four wheels of the machine. Fasten the boards with  screws.

  • Slide the four support beams included in the packaging under the ramp.

  • Remove the wooden blocks used for arresting the wheels and slide them under the ramp.
    Push the sweeper off the pallet (appliance without built-in battery)
    DANGER
    – Risk of injury! Before releasing the immobilizing brake, the machine must be secured to prevent it rolling away. After releasing the emergency brake, the appliance will roll until a speed of 4.5 km/ h is reached. After that, the electronics will brake the appliance.
    – It is prohibited to release the emergency brake on an incline without using the stopper.

  • Release parking brake.
    

  • Remove the brake level from the wheel and put it in its position.
    The immobilizing brake is thus deacti- vated; the machine can now be moved.

  • Slide the machine over the prepared ramp from the pallet. Drive the sweeper off the pallet (appliance with built-in battery)

  • Connect the battery, refer to Chapter “Connecting and installing the battery”.

  • Release emergency-stop button by turning.

  • Set main switch to “1”.

  • Press the drive direction switch and slowly move the machine down from the ramp.

  • Set main switch back to “0”.
