•
Handle the drive module carefully:

Use safety shoes with a metal toe cap to prevent foot injury.
•
Lift the drive module only by the lifting lugs.

Make sure that the module does not topple over when you move it on the floor:
Open the support legs by pressing each leg a little down (1, 2) and turning it aside.
Whenever possible secure the module also with chains.
•
Do not tilt the drive module (A). It is heavy and its center of gravity is high. The
module overturns from a sideways tilt of 5 degrees. Do not leave the module
unattended on a sloping floor.
