Nederman 810 Series Instruction Manual

Mounting
Hang the balancer directly over the work area by
the swivel fork provided at the top of the balancer.
NB! The support device should have a break
strength exceeding six times the combined weight
of the balancer and the load.
Tool Attachment
The balancer is furnished with a tool clip. Attach tool
complete with hose or cable and fittings. Warning!
Never pull the balancer tool clip down to the tool.
Always lift the tool up to the tool clip.
Cable stop/bumper Adjustment
Make all cable stop adjustments with the tool
attached to the tool clip and tension properly set.
Loosen cable stop and slide the cable up or down
to position tool at desired working height. Then
tighten the cable stop
Automatic Lock
If tension is too low or a spring should break, an
automatic lock will engage to prevent the drum
from turning.
Maintenance and inspection
The balancer is designed to require little mainte-
nance. Periodically check cable, tool clip, swivel and
hanger for wear. Replace all worn parts immediately.
The balancer is lubricated for life and requires no
additional lubrication.

Spring Tension Adjustment
NB! Attach full load including all attachments before
adjusting tension.
Increasing Spring Tension
If the tool attached to the balancer cable descends,
there is not enough tension on the balancer mainspring.
To increase tension:
1. Turn the mainshaft (a) with a wrench in a
counterclockwise direction.
2. Turn mainshaft 1/4 turn (1-click) at a time until
desired tension is achieved.
Decreasing Spring Tension
If the cable stop is up tight against the cable
guide, there is too much tension on the
balancer mainspring. To reduce tension:
1. Turn mainshaft (a) with a wrench in a
counterclockwise direction just enough
to release tension lock lever (b).
2. Push tension lock lever (b).
3. Slowly allow mainshaft to turn
clockwise and release tension lock
lever before allowing mainshaft to
rotate 1/4 turn (1-click).
4. Repeat this process until
desired tension is achieved.
If the spring tension has been increased
check that the required length of
the cable can be drawn out with-
out stretching the spring to the limit.
Warning!
Risk of personal injury!
Never remove the spring from the drum
and spring assembly. Replacement
springs are sealed for safety.
