Release the spring tension, proceeding as follows: Apply a size-

19 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 blocks the cable drum.

To prevent spring destruction, do not slacken it too much!

Unscrew the housing cover and the cable drum cover, then remove

the spring assembly from the drum. For models with two spring

assemblies : Remove the upper spring now. Should the lower

spring assembly still have some residual tension, unload the spring

completely by rotating the endless screw (9) in the "-" direction.

Thereafter, take the lower spring assembly out of the drum as well.

When replacing the spring assembly following spring fracture,

the housing, the cable and the cable drum must be checked

for damage and replaced as well where indicated, as high dy-

namic forces are released when spring fracture occurs and the

spring fracture safeguard mechanism is activated as a result

of this.

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 external lever of the cable fracture safeguard against

the spring assembly.

To ensure proper functioning, the external spring suspension

must engage with the drum slot and the internal 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 washers. 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:

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

Release the spring tension, proceeding as follows: Apply a size-

19 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 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 located

between the housing and the cable drum back onto the shaft if

appropriate. Unwind the cable from the cable drum, detach it and

pull it out of the housing. Remove the suspension (see Replacing

the suspension).

(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 ensuring 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 ring 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

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-19

socket spanner). Be sure that the cable winds up correctly in the

groove! Tension the spring and adjust the load as described under

"Replacing 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 and place the worm wheel 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 if

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.
