1.Depress the retaining pawl until it hits the bottom
and pull the grip ring towards you.
2.The chain can be adjusted up and down by hand.
3.To terminate the idling. Set the change lever in the

the outer edge of the retaining plate.
Thereafter, grip the grip ring and handle with a single
hand, push them in as it is rotated counterclockwise.

If the handle is locked under a shock load, the lock-
releasing mechanism acts to set the handle free to move.
In all models, 6 pinion gear teeth and 4 load sheave pawls
offer a large speed reduction ratio. The handle is by far
more responsive.
(Refer to dimension d in the specification on the table)
The short handle with a short stroke ensures the highest
working efficiency even in a narrow space.
The two-step "conscious" operation of pushing the positive
lever and pulling the grip ring helps prevent the accident of dropping the load due to a careless operation.
The load-bearing side plate is independent of the brake
support so that the side plate is protected against wraping
due to a local concentration of forces.
Sine one side is rigidly secured with a rivet-type stay bolt,
the frame is sturdy and free of displacement which is a
disadvantage of other levers.
