Replacing the drive module (frames R10 and R11)

This replacing procedure requires: preferably two persons, installation ramp, a set of
screw drivers and a torque wrench with an extension bar.
The drawings show frame R11. The details in frame R10 are slightly different.

•
Handle the drive module carefully:
•
Use safety shoes with a metal toe cap to avoid 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:
Extend 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.
