Replace the damaged spring by a new spring assembly. If a spring
of a different strength is used, the type and load range details must
be changed accordingly on the rating plate.
(B) Reassembly/ Reinstallation:
The spring assembly label must be visible when inserting the
spring assembly.
After a spring fracture: unlock the drum lock (see description
under Replacing the cable) and wind up the cable by rotating the
cable drum until the cable stop buffer comes up against the mouth
of the housing.
Insert the spring assembly into the cable drum, pressing the ex-
ternal lever of the cable fracture safeguard against the spring as-
sembly.
To ensure proper functioning, the external spring suspension
must engage with the shaft groove; if necessary, turn the shaft a
little with the endless screw (9) to enable the spring suspension to
glide into the shaft groove. First, screw the cable drum cover in
place, then the housing cover, using new tooth lock washer.
Apply the cover disk of the worm gear and screw it in place.
Tensioning the spring:
To set the maximum initial tension (preload), rotate the shaft
"X" times by turning the endless screw (worm) in the "+" direction:
615 805 021 0 X= 5
615 805 022 0 X= 6
615 805 023 0 X= 5
615 805 024 0 X= 5
615 805 025 0 X= 4
615 805 026 0 X= 4
615 805 027 0 X= 3
Install the balancer as described under Installation and adjust the
load as described under Adjusting the working load.

Never open the spring assembly! Defective springs must be
properly disposed of.
Replacing the housing
(C) Removal / Dismantling:
Release the spring tension, proceeding as follows:
Apply a size-17 socket spanner to the endless screw(9), then
turn the spanner in the direction of the "-" symbol until the cable
no longer retracts. The spring fracture safeguard now blocks the
cable drum. Do not slacken the spring too much in order to prevent
spring destruction.
Unscrew the housing cover disk of the worm wheel and remove
the disk.
Unscrew the housing cover. Remove the circlip on the worm
wheel using special pliers. Pull the cable drum with the spring and
the shaft out of the housing, paying attention to the feather key
located in the shaft. If necessary, force the shaft through the worm
wheel with a plastic-faced hammer. Put the brass washer locked
between the housing and the cable drum, detach it and pull it out
of the housing. Remove the suspension (see Replacing the suspen-
sion).
(D) Reassembly / Reinstallation:
Fit the suspension to the new housing (see Replacing the suspen-
sion). Insert the worm wheel into the housing, then insert the cable
drum with the shaft and the brass washer as well, pushing the shaft
through the worm wheel (thereby ensure that the feather key is
correctly positioned relative to the worm wheel; rotate worm wheel
if necessary). The shaft's ring groove must be visible. Insert the
circlip into the shaft's groove using special pliers.
Rotate the endless screw in the "+" direction to turn the cable
drum until the cable coupling is visible in the housing slot. Insert
EN
the cable through the mouth of the housing and install it as de-
scribed under Replacing the cable. Wind up the cable via the
endless screw, rotating it in the "+" direction (using a size 17
socket spanner). Be sure that the cable winds up correctly in the
groove!
Tension the spring and adjust the load as described under Re-
placing the spring assembly – see (B).
Replacing the cable drum
(Dismantle the balancer as described under Replacing the housing-
see (C). There is no need however, to remove the suspension from
the housing.
Installing a new cable drum:
Unscrew the cover and insert the shaft into the cable drum,
taking care that the ball bearing is not knocked out of the drum.
Put the brass washer on the shaft into the housing. Insert the
cable drum with the shaft and the brass washer into the housing,
pushing the shaft through the worm wheel. The feather key must
engage with the groove; rotate the shaft in necessary. Secure the
worm wheel with a circlip.
Insert the spring assembly into the drum as described under
Replacing the spring assembly (B) Reassembly/ Reinstallation.
Thereafter, install the cable as described under Replacing the
housing (D) Reassembly/ Reinstallation, section 2.
Replacing the suspension
(Remove the split pin, washer, bolt and tube of the suspension
from the housing, then remove the suspension as well. Insert the
new suspension, push the bolt through the housing suspension and
the tube, then secure it with the washer and a new split pin
