Disassembling for transportation
For easier transportation, the handle, the dust pipe, and the motor can be removed.
6.1
Removing the handle
There is the risk of injury or damage caused by an unintentional starting of the machine.
Disconnect the machine from the main power supply before working on the machine!
How to remove the handle:
1. Disconnect the motor and lamp couplings.
2. Fold down the power cord holder ( 1 ).
3. Fold the main lifting lever ( 2 ) to the front position to lower the sanding drum to the
fl oor. This removes load from the connecting rod ( 3 ).
4. Slide the clamp sleeve ( 4 ) to the top and take apart the two halves of the connecting
rod ( 3 ).
5. Remove the star-shaped knob ( 5 ), and you can lift off the handle.
