Checking the reserve stroke of the hoist brake thruster
The brake is released by an electro-hydraulic thruster when hoisting or lowering is activated.
Screw both screws (1.45) out of brake pad (4) at the opposite side of the thruster.
When the upper pin (5.2) is pulled out, the thruster will tilt and fall.
Secure the thruster against accidental movements.
