Safety instructions
Safety instructions
• To reduce risk of injury, everyone using, installing, repairing, maintaining,
changing accessories on, or working near this balancer must read and under-
stand these instructions before performing any such task.
• Our goal is to produce tools that help you work safely and efficiently. The
most important safety device for this or any tool is YOU. Your care and
good judgement are the best protection against injury. All possible hazards
cannot be covered here, but we have tried to highlight some of the important
ones.
• Only qualified and trained operators should install, adjust or use this bal-
ancer.
• No changes may be made on the balancer or its accessories without the ex-
press written permission of the manufacturer.
• The safe use of these products is only ensured if you have fully read these
operating and safety instructions and strictly observe them during work.
• Hook or unhook the load only when the cable is fully retracted.
• The fixture(s) on which the balancer and the safety chain are installed must
be sufficiently stable.
• The balancer cable must be checked for potential damage at regular inter-
vals – at least once a year – by a competent person. Never use a balancer
when the cable is defective.
• The suspension, the anti-crash safety device and the safety chain must be
monitored continuously. If damage or wear is detected, withdraw the bal-
ancer from service at once.
• Please note that the cable can easily get displaced from its coupling if it is
moved backwards, or snaps back, in no-load condition during installation.
An incorrectly anchored cable can slip out under load and cause bodily in-
juries or other damage due to the load crashing down.
• Except for cable replacement (see section “Replacing the cable”), the spring
tension must be fully released before performing any service or repair work.
Disassembling the spring housing is extremely dangerous and therefore
strictly forbidden.
• It is strictly forbidden to operate the balancer without the safety components
supplied (safety chain, spring fracture safeguard, etc.).
• A safety chain strained by a falling balancer must be replaced at once, to-
gether with the balancer’s housing.
For additional safety information consult:
• Other documents and information packed with this tool.
• Your employer, union and / or trade association.
• “Safety Code for Portable Air Tools” (ANSI B186.1), available at the time
of printing from Global Engineering Documents at http://global.ihs.com/ ,
or call 1 800 854 7179. In case of difficulty in obtaining ANSI standards,

Installation hazards
• Make sure the balancer suspension method and supports have a minimum
safety factor of five times the combined maximum load capacity plus bal-
ancer weight.
• Attach an additional support cable or chain to a support independent of the
one holding the balancer.
• Examine the suspension hooks, cable and chain for wear. Replace any worn
parts before installation.
Use Hazards
• Examine suspension hooks, cables, cable stops and chains daily for wear.
Replace worn parts before further use.
• Never lift people or lift loads over people.
• Never use balancer cable or chain as a sling.
• Load chain must not be twisted, kinked or damaged when lifting a load.
• Centre balancer over load before lifting.
• Operators must be physically able to manoeuvre the balancer.
Workplace Hazards
• Slip/Trip/Fall is a major cause of serious injury or death. Be aware of excess
hose left on the walking or work surface.
• Hard hats are recommended in areas where balancers are in use.
• Proceed with care in unfamiliar surroundings. Be aware of potential hazards
created by your work activity.
• Balancers are not insulated from coming into contact with electric power
sources and are not intended for use in potentially explosive atmospheres.
Maintenance and repair hazards
• Read and understand instruction and parts book before servicing this prod-
uct.
• Maintenance personnel must be physically able to handle the bulk and
weight of the balancer.
• This product and its accessories must not be modified.
General information

Installation
Installation
Prior to installing the balancer, verify that the suspension structure to which the
balancer and its safety chain are fastened provide adequate stability.
To install the balancer, be sure to proceed as follows:
• Via the safety suspension, suspend the balancer so that it can be easily
aligned and moved in any working direction.
• It is mandatory to mount the supplied safety chain in addition to the safety
suspension. Note that the maximum falling distance permitted is 100 mm! It
must be guaranteed that the anti-crash safety device does not interfere with
the balancer across its entire working range.
• Attach the load to the screw-type spring hook installed at the cable end, then
close the hook and screw the knurled lock nut in place.
• Adjust the balancer to the working load (see section “Adjusting the working
load”).
Adjusting the cable length
The balancer is delivered from the factory with a long cable, so that the cable
length can be individually adjusted to the onsite circumstances. Adjusting the
cable length is done with the cable wedge (7). After lengthening or shortening
the cable, the free cable end must be compressed with the supplied ferrule (8)
(or a clamp in accordance with DIN 3093 Pts. 1 to 3); the projecting cable end
must then be cut off flush.
A minimum distance of 100 mm must be maintained between the cable
clamp (6) and the cable wedge (7).
