Intended Conditions Of Use - PREVOST BAL 250300F Operating Manual

GB
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 that the user must adhere to 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.

Intended conditions of use

The balancers are designed to balance the weight of tools and utensils in general and are to be used by one
operator at a time. The balancer may be used in an assembly line, in single workplaces, in professional or private
environments, as a hobby, etc..
Always operate, inspect and maintain this balancer in perfect working order in accordance with
all regulations pertinent to balancers, tools and workplaces.
Use contraindications
• Do not use the balancer in environments with potentially explosive atmospheres.
• Do not permit children or people under age to use the balancer.
• Do not work, transit or linger underneath the balancer.
• When using balancers, always fully and duly comply with the standards and laws in force in the country in which
they are used.
PREVOST will not be held liable for any damage or problems caused by customers using these balancers for
any other application.
Choosing the balancer
Assess the total load to be balanced: tool, accessories and sections of hoses or cables to be lifted by the balancer.
The overall load to be balanced must fall within the balancer's minimum and maximum load-bearing capacity.
Starting up the balancer
Assess the range of the work area and, if need be, hang the balancer on a carriage to be able to use it properly
in an area wide enough to carry out the required activities.
If screw-fixing devices are used to install the balancer, use self-locking nuts, split-pins or other safety systems.
The balancer must be installed on a structure having an adequate mechanical resistance. Mechanical resistance
of the structure > 5 x (Balancer weight + Max load).
It is possible to install more than one balancer to the same main structure only if each balancer has an independent
connection point and the structure has a mechanical resistance higher than five (5) times the weight of all balancers
plus all maximum load.
When starting up a balancer, we suggest that the following procedure is used:
- Connect the balancer to the main structure through the suspension hook, if present, or fixing hole.
- Connect the safety device to the secondary structure.
- Lift the load to be hanged to the balancer.
- Hang the load to the balancer through the proper hook/snap hook.
- Lower the load by unwinding the balancer's rope and adjust the stroke limiter clamp to avoid bringing the load
above the operator.
- Adjust the balancer strength as long as the hanged load is balanced. Rotate in the direction of the + sign to
increase the strength of the balancer. Rotate in the direction of the – sign to decrease the strength of the balancer.
In case of installation of the balancer at a considerable height, use the dedicated extension ropes to bring the
load at the needed working height (the load must not be above the operator).
Ensure that the working area is adequately lightened to allow a good overview of the operations and of all the
equipment, avoiding dark areas, dazzling and strobe effects.
