•Turn the handle (66) clockwise to lift the front off the ground.
•Release the brake (68) and make sure the floating shroud is in transport mode (65).
•The traction wheels must be disconnected from the drive motors, pull out the locking pin of each rear
wheel (54) to disconnect the wheels from the drive motors.
The machine can now be pushed around manually.
Another way to move the machine manually is by putting the steering handle in the upright (vertical) position
and putting the side-weights slightly backwards. Disconnect the traction wheels by pulling out the fast locking
pins (54). Stand with one foot on the bracket and pull on the handgrips to tilt the machine backwards. It can
now be pushed around on its back wheels.
The machine should only be moved around when the dust
hose, water supply and power supply cable are disconnected.
Be careful when you let the machine tilt back on the grinding heads, let the machine down slowly, big shocks
can damage the electrical parts.

When using DIAMAG adapter plates, you can replace
the diamond wings without using any tools!
Because of the specially designed heat resistant magnets
and fixation pins, the diamond tools are fixed onto the
plate, but can still very simply be replaced by hand.
