In the very rare case of load compensation between the
car and the counterweight, the electric return motion
control must be used.
When required and if expressly ordered, the attachable
manual turning device No. 504 090 (35) can be supplied.
This completely assembled device is composed of a worm
wheel (36) with two stationary plug-in bolts (37), a worm
gear shaft (38) with a hand wheel (39), the bearing block
with the stop plate (40), the centre bolt (41) and two fas-
tening bolts (42). The centre and fastening bolts are cap-
tivated with nuts which must be removed when the
device is to be used.
The manual turning device is available in three versions:
Use of the manual turning device is the sole responsibili-
ty of the user. All W7/W8 lift machines with delivery
dates on or after 10/2005 are designed for attachment of
this complete device.
If such a manual turning device is provided, the lift
machine is equipped with the safety switch (43) shown
opposite, which must be incorporated into the safety cir-
cuit of the lift system.
Operating data of the safety switch:
During normal operation the safety contact remains
closed by virtue of a bow on the switch cover. Before
using the manual turning device in an emergency, this
cover (34) (4xM6 wing nuts) must first be removed. The
two pinholes - 15 in dia. and 60 mm apart - in the shaft
of the lift machine will then be visible. Turn the hand
wheel (39) of the manual turning device so that the posi-
tion of the plug-in bolts (37) approximately matches that
of the pinholes. Remove nuts from the bolts 41 and 42
(captivation), then lift the device onto the lift machine in
a position where the two plug-in bolts (37) slip into the
pinholes in the shaft and the stop plate (40) of the
device is brought up axially to the bearing battens (44)
of the frame. Then screw the centre bolt (41) loosely into
the tapped hole in the shaft. With the turning device

1. Insert all Bowden cables into the lever block, making
sure that the nut (1) is screwed flush onto the stud
bolt (2).

wound.
4. Preload the Bowden cables by turning the nuts on the
stud bolts (2). The brakes must not yet release (
