Brake and pawl

The brake system needs a minimum load of 3% of the capacity.
Only this minimum load makes sure that the load-pressure-brake closes correctly. When the brake closes
correctly, the load is safely held.
DANGER!
Working situations with no guarantee that the minimum load is charged, are forbidden!
The brake remains closed (stuck) if:
 The ratchet lever hoist is uncharged without lowering the load, i.e. in case of vertical lifting/lowering or in
case of horizontal pulling/tensioning.
 The load hook is pulled against the housing and got stuck there.
The chain does not move, the load cannot be lowered.
Remedy:
 Charge the ratchet lever hoist again
 Release the brake by setting down the load.
 OR: Turn the switching pin to position "Lowering" and release the hand lever with a strong jerk in direction
"▼".
