Adjusting the suspension
Fine adjustment of the suspension is possible to ensure low-wear
cable and drum operation. To this end, adjust the suspension hook
along the bolt so that the balancer is suspended in a more or less
horizontal position within the working area.
The hook distance to be maintained on the left above the housing
slot should be as follows for the various load ranges, relative to
the specified maximum load (factory setting):
615 805 028 0 = aprox. 1 mm
615 805 029 0 = aprox. 1 mm
615 805 030 0 = aprox. 1 mm
615 805 031 0 = aprox. 1 mm
615 805 032 0 = aprox. 1 mm
615 805 033 0 = aprox. 1 mm
615 805 034 0 = aprox. 1 mm
615 805 035 0 = aprox. 1 mm
Proceed as follows: Loosen the suspension's clamping screw (3),
move the suspension appropriately, then retighten the clamping
screw (3).
Adjusting the working load
The balancer has been factory-preset to the maximum load permiss-
ible for the type/model in question.
– After attaching the load, apply a size-19 socket spanner/ wrench
to the endless screw (9), then rotate the spanner in the direction
of the "-" symbol until the weight of the suspended working
load is exactly counterbalanced.
– When setting the minimum load, never extend the cable beyond
a length of 1.5 m, as otherwise the spring fracture safeguard
may be tripped. In case the safeguard mechanism has already
been activated, first carefully preload the spring in the "+"
direction as far as it will go (the spring is now fully "on block"),
then adjust the tension again to the working load by rotating
the endless screw (9) in the "-" direction.
– To prevent spring destruction, do not slacken it too much! Full
spring release is permitted only if no load is connected!
– Infinitely variable load adjustment is possible within the balan-
cer's load range (see rating plate (1) for details). To adjust to
lighter working loads, simply rotate the endless screw (9) in
the "-" direction; for heavier loads, rotate it in the "+" direction.
Note that the balancer may not be operated outside the working
range indicated on the rating plate!
The manual drum lock should never be used for load replace-
ment!
Cable stop buffer / Setting the cable extension
The cable stop buffer can be moved simply by moving the flexible
cable stop buffer and the cable clamp. The cable clamp should be
secured each time.
A
WARNING: The maximum cable extension length must not be
exceeded (even with a cable extension).
Drum lock
The drum lock (10) allows you to block the drum for cable replace-
ment, without any need to unload the spring (see description under
Replacing the cable).

Maintenance
Servicing / Inspection
The balancer must be serviced continuously. All external moving
parts as well as the friction points on the suspension and spring
hook must be greased. For cable care, we recommend non-corros-
ive grease because it significantly increases the cable's useful life.
The suspension, the safety chain, the spring hook and the cable
must be monitored continuously and needs to be checked by a
competent person at least once a year. If damage (such as broken
strands, "cage-type" bulging, flattened places or abrasion) is found
on the cable, or if any of the above-mentioned parts show signific-
ant signs of wear and tear, the balancer must be withdrawn from
service and replaced immediately. Should the cable, spring or
other parts of the balancer need to be replaced, pre-assembled re-
placement sets are available.
Maintenance
The following sections refer exclusively to our pre-assembled re-
placement sets: cable, spring & cable drum, housing, and suspen-
sion. Be sure to use only genuine spare parts for replacement.
When replacing any of the above-mentioned components, always
follow the Operating Instructions supplied with the product.
Changing the cable
With this balancer it is possible to change the cable without releas-
ing the spring and without dismantling the device.
The "cable complete" replacement part set consists of the cable
with a pressedon clamp on the on the cable coupling, a separately
enclosed brass bush, the cable stop buffer with rubber ball and
cable clamp, plus the pre-assembled cable socket with wedge and
a ferrule (steel clamp) for pressing onto the free cable end after
adjusting the cable length, supplied loose.
Pull the cable out of the housing as far as possible. (The cable
coupling is visible in the lower part of the aperture in the housing.)
Lock the cable drum by turning the fixing pin (pin with elongated
slot on the small housing diameter) is pressed in with a screwdriver
and in this position is turned optionally right or left through 90°.
A
Ensure that the cable drum is securely locked. Snapping back
of the cable in a no-load condition by unlocking the cable drum
can lead to injuries and cause the spring to be destroyed.
Push the cable upwards out of the cable drum, remove the bush
from the cable and pull the cable downwards out of the balancer.
Introduce a new cable from below through the housing mouth
and the hole in the cable drum ("Tunnel") and push it through
upwards. Push the bush over the cable onto the ferrule. Pull the
cable in downwards into the cable drum hole ("Tunnel"). Ensure
correct coupling: the cable with the bush must be clearly and dis-
tinctly anchored in the cable drum.
Suspend the working load and set the cable drum in motion by
pulling the cable out slightly and pulling the steel pin out of the
locking device.
A
An incorrectly anchored cable can break out of the coupling
under load and cause consequential damage.
Suspend the load range and set the cable drum in motion by first
pressing in the fixing pin and then, optionally unloading by 90°,
turning it right or left, until it jumps back into the original position.
Replacing the spring assembly with the spring
fracture safeguard
(A) Removal:
Retract the cable fully, then remove the load. In the event of
spring fracture, lock the cable drum as described under Replacing
the cable. Take the balancer off its suspension.
