Operating & Safety Instructions
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. For professional use only.
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.
Chicago Pneumatic 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.
Use hole A (Fig.1) for the main suspension and hole S (Fig. 1) for the safety
suspension.
If screw fixing devices are used to install the balancer, use self-locking nuts,
split-pins or other safety systems.
Always connect the safety suspension S, using exclusively the supplied
standard fittings (Fig.1), to a suitably sized support. The safety support
MUST NOT BE the same one used for the main suspension A (Fig.1). If the
main suspension breaks,
the max falling distance must not be more than 100 mm(3.94 in.). Tighten the
nuts of the clamp 21215 (Fig. 1) at a torque of 2 Nm(1.47 ft. lb).
To avoid anomalous wear, the load must be applied vertically and in any case
the cable must be free to line up with the direction of the load.
Using the balancer
Grip the tool hanging from the balancer and carry out the required operations.
Then accompany the tool until it balances, on the vertical line of the balancer,
and release it.
The load to be balanced must be hung on hook 14 Fig.2. Ensure that the hook is
properly closed after having hung the load.
The cable must never unwind all the way: the work stroke must end at least 100
mm before the stroke's lower limit.
If need be, move and lock the clamp 12 Fig.2 to stop the upward stroke.
When using the balancer, always don individual protective gear and closely
adhere to the prevailing accident prevention regulations.
It is strictly prohibited to:
- Abandon the load if it is not in a vertical position;
- Swing/throw the hanging load to another operator;
BALANCER MAINTENANCE
This part of the manual is intended for maintenance personnel
ONLY
CERTAIN OPERATIONS OUTLINED IN THIS SECTION
ARE VERY DANGEROUS AND COULD INJURE PEOPLE IF
PERFORMED BY UNSKILLED PERSONNEL.
REFER TO THE OPERATING MANUAL TO INSTALL, ADJUST
AND USE THE BALANCER.
Maintenance
The balancer's dimensioning is such that it is maintenance-free for
its entire work life. But if it is used under particularly harsh
conditions and requires any interventions, ensure that the spring-
drum group (7) is unloaded before disassembling the balancer.
The spring is the balancer's only dangerous component. It is housed
inside the drum (7) that is lubricated for life. The spring-drum spare
part (7) is supplied complete: do not remove the spring for any
reason whatsoever.
WARNING: before carrying out any type of check, make sure
the spring is discharged in actual fact.
WARNING - DANGER: never open the drum and/or attempt to
replace the spring for any reason whatsoever. This operation is
extremely dangerous and could cause very serious injury.
- Move the load by pulling the balancer's cable;
- Hang loads that are not within the upper and lower ranges of the admissible
load-bearing capacity;
- Hang more than one tool on the balancer.
The sole risk linked to the use of the balancer consists in any uncontrolled
rewinding of the cable. This very dangerous event will be avoided by
adhering to the following instructions:
- if you have any doubts concerning the working efficiency of the balancer,
BEFORE performing any kind of inspection be sure to hold up the hanging tool
to prevent it from falling and UNLOAD THE SPRING COMPLETELY;
- if for any reason whatsoever the balancer does not rewind the cable, DO NOT
do anything on your own initiative but contact the customer service at once;
- never release the load if the cable has not been fully wound in the drum;
- should you find the balancer with the cable unwound and no load applied to it,
DO NOT do anything on your own initiative but contact customer service at
once.
Adjusting the balancer
To allow the balancer to balance heavier loads, turn the knob 4 as shown in
Fig.2 (counter clockwise, identified by the + symbol. The adjustment is not
continuous – it is jerky): after every jerk, knob 4 must touch the plate 5 Fig.
2. As concerns lighter loads, pull out knob 4 and, grasping it firmly, turn it as
shown in Fig. 3: after every jerk, the knob must touch the plate 5 Fig. 3.
After having adjusted the load, check that the cable slides freely for its entire
length: the movement must not be restricted when the spring has wound all the
way. Check the stroke often and at different speeds.
NOTE: should the balancer's capacity of supporting a hanging load
decrease, this could mean that the spring of the drum is about to break.
DO NOT MODIFY BALANCER ADJUSTMENT TO MAKE IT HOLD UP THE
LOAD IN ALL CASES BUT CONTACT SKILLED PERSONNEL IN CHARGE
OF MAINTENANCE AT ONCE.
INSPECTIONS AND MAINTENANCE
Maintenance may be carried out only by skilled and authorized personnel.
- The user must visually inspect the balancer on a regular basis (such as, for
instance, at each work shift) especially to check the state of suspensions A
and S (Fig. 1), the fixing screws and the self-locking systems (if used), and the
condition of the hooks and cable.
Should the cable have the defects shown in Fig.4, replace it immediately.
Do not make any modification to the cable unit and, specifically, DO NOT
SHORTEN the cable: if need, please get in touch with Chicago Pneumatic
- check that the cable's movement is smooth and that it does not make any
strange noises;
- do not lubricate the balancer with flammable or volatile fluids;
- do not remove any labels. Replace any damaged labels;
- the balancer must be inspected at least once a year by skilled, authorized
personnel.
Never disassemble the balancer. Maintenance is to be carried out only by
skilled, authorized personnel.
The balancer must be disposed of complying with prevailing rules and
regulations at the end of its work life.
Warranty
The use of non original Chicago Pneumatic spare parts will negatively affect
safety and performance and will, in any case, void the warranty.
WARNING: replace the entire drum (the spring is NOT supplied as
a separate spare part).
WARNING - DANGER: dispose of the drum containing the
broken spring as specified by prevailing laws and regulations.
DO NOT abandon it or dispose of it together with other types
of waste and/or scrap because if it opens, even by accident,
it is VERY DANGEROUS and could cause serious damage to
anyone.
Use original Chicago Pneumatic spare parts only. When
requesting spare parts, the Customer should kindly contact the
supplier of the balancer, or the manufacturer directly, specifying the
machine's identification data printed on the plate.
