5-2-2 Installation of tools and equipment and adjustment of the spring tension
WARNING
Do not pull out the hose when the balancer is not loaded. If the hose is released by
mistake while being pulled out without a load, it may quickly be wound up, causing
an injury.
NOTICE
If the spring tension is set higher than the maximum capacity, not only will the
specified stroke not be obtained, but the life of the spring will also be reduced. On
the other hand, if the spring tension is set lower than the minimum capacity, the fall-
arrest device will be activated and prevent the vertical movement of the tool
(equipment).
1
Check whether the total mass (weight) of the tool (equipment)
and the accessories is within the capacity range of the
balancer.
2
Lift the tool (equipment) and attach it to the hose end of the
balancer (swivel joint).
At this time, do not pull out the hose.
3
Turn the worm to adjust the spring tension.
•
The tension will increase if you turn the worm in
the “+” direction (clockwise).
•
The tension will decrease if you turn the worm in
the “-” direction (counterclockwise).
4
Ensure that balance is achieved.
5-2-3 Releasing the fall-arrest device
After the fall-arrest device is
activated, for example, when
the spring tension is reduced
too much, the fall-arrest device
can be released by turning the
worm to the “+” direction
(clockwise) and increasing the
tension with the tool
(equipment) attached.
REMINDER
When the mass (weight) of the tool (equipment) exceeds the
spring tension, the tool (equipment) moves downward.
Keep your hand on the tool (equipment) and slowly lower it.
NOTICE
If the spring tension is too strong,
the main equipment of the balancer
or the hose may be damaged.
