Action Note
1. Move the upper arm to one of the basic
positions:
• upper arm is pointed straight up. This
position enables the motor to be
replaced without draining the gear
oil, which in turn saves time.
• upper arm is close to horizontal. This
position is recommended if the
gearbox is also to be replaced, i.e.
when the gearbox oil has to be
drained anyway.
