INSTRUCTIONS FOR MODEL BSD-NFRU AND BSDL-NFRU HEAVY DUTY BALANCER
IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PLACE THE INFORMATION
FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.
FORSEEN USE
Models BSD-NFRU and BSDL-NFRU Heavy Duty Balancers are
designed to counter-balance the weight of Power Tools.
Ingersoll Rand is not responsible for customers using these
balancers for other applications on which Ingersoll Rand was not
consulted.
PLACING BALANCER IN SERVICE
Always operate, inspect and maintain this balancer in accordance
with all regulations (local, state, federal and country), that may apply
to hand held, hand operated power tools and balancers.
Calculate the total load to be supported by the balancer:
equipment, accessories and those sections of hose or cable to
be lifted by the balancer. The whole load to be balanced must be
within the specified capacity range of the balancer. (See balancer
capacity shown in the specifications).
To achieve the best performance, hang the balancer by the hook 23
at a height which allows the use of the central section of the cable
stroke 15.
The balancer can be suspended from a fixed point or from a traverse
system which is perfectly horizontal.
To avoid anomalous wear the balancer must always be free to rotate
and line up with the cable 15, even when the load is not in a vertical
line with the balancer.
Connect the suspension S with a flexible cable to a suitable support
leaving a maximum extra stroke of 100 mm (Fig. 1). The balancer
must be free to rotate.
If screwed fasteners are used to connect the balancer, either self
locking systems and/or split pins should be used.
With knob 1 in its working position (Fig. 3a), hang the load on the
bottom hook.
Do not lubricate balancers with flammable or volatile liquids such as
kerosene, diesel or jet fuel.
Do not remove any labels. Replace any damaged label.
Refer to adjustment instructions in this manual.
USING THE BALANCER
When the balancer with its load is installed, check that working
conditions are correct (smooth movement with minimum effort).
For a correct and safe use periodically check the status of the upper
attachments 23 or S (if screws are used, the status of self locking
systems and/or split pins should be checked).
Periodically check that parts under strain (hook, cable, balancer
suspension parts and connections to the tool) are safe and not
weakened by wear.
Never unlock the balancer with the cable extended or not
attached to the load. The cable could rewind at an uncontrolled
speed causing injury.
The main balancing spring, together with its housing drum and the centrifugal safety disc are only supplied as one complete item (13).

Ingersoll Rand Office or Distributor.

IMPORTANT SAFETY INFORMATION ENCLOSED.
READ THIS MANUAL BEFORE OPERATING BALANCER.
IN THIS MANUAL INTO THE HANDS OF THE OPERATOR.
WARNING
It is dangerous for unqualified personnel to dismantle this balancer.
WARNING
When the balancer is not working (for example when being
transported or in storage) the cable 15 must be fully retracted inside
the balancer, with the rubber stopper 55 fitted against guide 29.
ADJUSTMENTS
To increase capacity rotate the regulating screw 44 (51) in a
clockwise direction.
To decrease capacity, rotate the regulating screw 44 (51) in a
counter-clockwise direction.
After adjusting the load, check that the cable 15 runs for its full
length and is not limited by a fully loaded spring 14.
When the balancer with its load is installed, check that working
conditions are regular (movement with minimum effort). During
operation the cable must not unwind its total length. It must stop at
least 50 mm before the lower limit of the stroke. If necessary adjust
the clamp 32-32 (32-34) to limit the upwards stroke. (Fig. 8).
To lock the load at the desired height turn the knob 1.
Control from the floor option
For floor controlled versions, operate the handgrip 50 (Fig. 2) by
pulling the red side down to lock the load at the desired height. To
get the free stroke of the balancer, pull down the green side.
Note: Knob 1 or cam 50 should be in a stable position at the end of
the stroke.
Never unlock the balancer with the cable extended or not
attached to the load. The cable could rewind at an uncontrolled
speed causing injury.
Centrifugal weights locate on steel stop inside the balancer if over-
acceleration occurs (Fig. 4).
Locking device against load dropping due to a breakage of the
main spring 14 (Models BSD-NFRU 20, 60, 70 and 100 and BSDL-
NFRU 20, 35, 45, and 100 (Fig. 7); Models BSD-NFRU 120, 180 and
BSDL-NFRU 115, 180 (Fig. 9b)).
Adjustment for an insufficient load can also cause this mechanism to
activate by causing the drum 14 to stop at the higher part of the stroke:
this is shown by the screw 44 protruding for approx. 4 mm (Fig. 7).
To avoid this problem:
1) Increase the load on the balancer (screw 44 (51) turned clockwise).
2a) Rotate locking pin 9 (Fig. 5a, b, c) (Models BSD-NFRU 20, 60 and
BSDL-NFRU 20, 35).
2b) Rotate cam 5 (Fig. 5) (Models BSD-NFRU 70, 100, 120, 180 and
BSDL-NFRU 45, 100, 115, 180).
3) Limit the stroke to the minimum by moving clamp 32-32 (32-34)
upwards.
If this does not eliminate the stopping of the drum, replace the
balancer with one of a lower capacity.
