ATTENTION: instructions marked by symbol
are critical for the use of the balancer in envi-
ronments with potentially explosive atmospheres.
WARNING: this device is suitable only for use in environments having potentially explosive
atmospheres for GAS, DO NOT use this device in environments having potentially explosive
atmospheres for DUST.
Install the balancer before using it. This operation is to be carried out by skilled personnel who
must comply with the directions outlined in this manual:
A WRONG INSTALLATION COULD CAUSE INJURY/DAMAGE TO PEOPLE/PROPERTY.
This manual contains important information in order to use the balancer safely.
Be sure to have clearly understood all the instructions before using the balancer.
FAILURE TO DO SO COULD CAUSE INJURY.
The balancer was built in conformity with European Community Directives that were pertinent and applicable when the balancer was
put on the market and that entail the CE marking of the product.

The intended use of a balancer is to eliminate the constant weight of a tool during a vertical movement.
The balancer is only intended to be used manually by one operator at a time.
The balancer is intended to be used indoors with temperatures between 5°C and 60°C.
For a better use of the balancer, it is recommended that the load is suspended at the centre of gravity.
It is necessary to use, inspect and maintain the balancer in perfect working efficiency in accor-
dance with every regulation with regard to balancers, tools and workplaces.

Static and Dynamic sample testing (Machine Directive 2006/42/EC, Annex I, section 4.1.3) are performed for each production lot.
The static tests are performed by connecting to the balancer a load 1.25 times higher than the maximum allowed capacity then by
accompanying it to the stroke end (rope all out) for 10 minutes (as reported on DIN 15112:1979).
The dynamic test is performed by checking the proper operation of the balancer (rope extraction and rewinding) for 1-hour time with
the balancer charged 1.1 times the maximum allowed load.

ATTENTION: when choosing the balancer, check that the ATEX classification on the plate is
suitable to the environment, the type of potentially explosive atmosphere and the intended use.
