General safety
Please read the instructions for use before using the balancer. Safe working with the machine is only possible if you have read the instructions for use and safety information in full, have understood the instructions contained therein and observe them strictly.
Never remove safety devices like Safety suspension (2), (3) or Load hook (9)), or deactivate them by modification. In the event of a fault or defect, stop using the balancer and inform the responsible supervisor. This is the case, for example, when a balancer falls into the chain. Further use must be assessed by trained and qualified personnel and damaged components must be replaced.
The operator must trained before working with the balancer in accordance with the instructions given in these instructions for use.
Overview
Application
The balancer is used for relieving the weight of hand-held tools and makes the use of the hand-held and simple multi-fixtured tools much easier.
The retraction forces remains nearly constant over the whole wire extension length. The load range differs depending on model.
The ambient temperature for the use of the balancer is -20°C to +70°C.

Installation
Installation Instructions
Installing the balancer
Install the balancer so it can easily be aligned and moved in any direction. The wire must to be able to move without any additional force.
If a cable or any other accessory is attached to the wire, it might shorten the lifetime of the wire, and this may cause the wire to break due to fatigue. Do not attach a tool cable or any accessory to the balancer wire without consulting Atlas Copco.
Install the supplied auxiliary chain.
Make sure that the auxiliary chain is not too long or too short to interfere with the balancer across its entire working area.
The chain is always mounted on a separate mounting point from the balancer to prevent risks.
The permitted maximum falling distance is 100 mm.
Before installation make sure that the balancer suspension attachment and the auxiliary chain fixture is safe and stable.
Attach the workload to the snap hook at the cable end.
Adjust the workload, see “Adjusting the workload”.
Adjusting the workload
The balancer is factory set to carry a maximum workload.
To adjust the balancer to carry different workloads, turn the endless screw on the balancer in minus (-) or plus (+) direction.
(-) for lighter workload
(+) for heavier workload
WARNINGRisk of endless screw
The endless screw can be damaged if it is loosened or tightened past the end positions.
Stop turning the endless screw at the end positions.
Attach the workload on the snap hook.
Turn the endless screw in minus (-) or plus (+) direction to adjust the counterbalance weight.
To turn the endless screw use a hexagon key for WP 105; press and turn
Setting the initial tension of the balancer
WARNINGRisk of Injury
It is of high importance that the wire retracts in a slow, smooth motion. A too rapid retraction will make the wire lash, which might cause the wire to break, with property damage and/or bodily injury as a result.
The initial tension of the balancer need to be set if the spring has been released during service.
To get the maximum initial tension of the balancer, turn the endless screw in the plus (+) direction x number of times, refer to the table below.
4390190173 | x = approx 11 |
4390190174 | x = approx 5 |
4390190175 | x = approx 6 |
4390190176 | x = approx 5 |
4390190178 | x = approx 4 |
4390190179 | x = approx 11 |
4390190180 | x = approx 5 |
4390190181 | x = approx 6 |
4390190182 | x = approx 5 |
4390190183 | x = approx 4 |
Setting the minimum workload
When setting the minimum workload, never use a wire length of more than 1.0 m as the spring fracture device may release.
If the spring fracture device releases:
Carefully adjust the spring tension in the (+) direction.
Attach the workload.
Adjust the counterbalance weight of the workload by turning the endless screw in the minus (-) direction.
Locking the wire drum
The drum lock blocks the wire drum. When the wire drum is locked it is possible to replace the wire without decreasing the spring tension.
Push the drum lock fixing pin as far as possible and turn it 90° using a flat screwdriver.
Make sure that the wire drum is locked.
Unlock the wire drum by turning the drum lock fixing pin back to the start position.
Make sure that the workload is attached and the spring tension is adjusted before unlocking the drum.
Adjusting the wire extension length
Maintain a minimum distance of 100 mm between wire wedge (6) and wire clamp (5) during installation. Otherwise, increased wear and premature failure are possible.
Loosen the wire clamp.
Move the wire clamp and wire stop buffer to the wanted position.
Tighten the wire clamp.
WARNINGRisk of Wire Damage
Risk of wire damage if the wire extension length is extended too far.
-
Do not pull on the wire when the end stop is reached.
Adjusting the wire length
Only applicable to WP models that have a wedge adjustment at the lower attachment point.
The balancer is delivered with a long wire so that the wire length can be adjusted to the on-site circumstances.
The minimum distance between the wire clamp and the wire wedge is 100 mm.
Remove the clamp from the wire wedge.
Adjust the wire length.
Make sure that the distance between the wire clamp and the wire wedge is no shorter than 100 mm.
Put the clamp back on the wire wedge.
Tighten the wire end with the supplied ferrule or a clamp in accordance with EN 13411-3:2022.
Cut the remaining wire end straight off.
