BALANCER SER. 831
Mounting instruction
If the balancer is used to support exhaust extractor hose to
Nederman exhaust rail, the balancer must first be fitted to
the rail's exhaust trolley according to the instructions that
comes with the exhaust rail. Then follow the following
instructions.
Fit the balancer's cord in the hose coupling directly under
the cord stop as figure A shows.
The balancer is equipped with a brake which should be in
operation as long as the hose and nozzle, after the
disconnection from the vehicle exhaust pipe, are moving
horizontally along the floor.
Checking the braking function
Check that the brake is disconnected 0,1 -1,0 m before the
nozzle is leaving the floor and is hoisted up vertically (see
figure B). The brake disconnects when the cord is pressing
a button on the balancer drum (see figure C).
If the brake does not disconnect at the right moment, take
following measures:
a) Check and adjust the measure 10 - 12 mm on the
adjusting nut on the reverse side of the balancer
(see figure D).
b) Move the balancer cord stop and the cord fitting in the
hose coupling slightly upwards or downwards.
WARNING!
Risk for personal injury and/or damaging vehicles!
When using the balancer to support exhaust extractor
hose, the hose must return in a steady and even
manner. To check after fitting, fully extend the hose
and release. The balancer should gently wind the
hose in. When needed, adjust the lifting power
according to the following instruction.
Adjusting the lifting power

When adjusting the lifting power of the balancer, it
is important to check that the amount of spare line is
correct. For 3" dia. hose 5 turns are recommended, for
4" - 6" dia. hose 3 turns are recommended. This length
can be altered by winding line on or off the conical
drum on the balance unit. Move the line stop and hose
accordingly.
Increasing lifting power
2
Pull approximately 2 metres of line
off the balancer.

Hold the block still and wind on a
couple of turns of line.
Reducing lifting power
