• Push the DOWN operation button on the remote pendant to wind the primary suspension wire rope out of the hoist.
To remove the last 15 inches (40 cm) of wire rope, if necessary, grab the wire rope above the primary suspension
wire rope insertion point, hold the overspeed brake reset knobin the reset position (vertical) and slowly pull the
primary suspension wire rope out of the hoist.
Dereeving Secondary Suspension Wire Rope
• In order to remove the secondary suspension wire rope, there must be no slack on the primary suspension wire rope
and the platform must be supported on a stable surface.
• Remove the counterweight from the end of the secondary suspension wire rope.
• Pull the secondary suspension wire rope out of the hoist by hand.
• If necessary, the primary suspension wire rope can now be removed from the hoist.
Daily Testing and Inspection
• Before operating the hoist, inspect the following:
▫Wire rope
▫Power supply
▫Rigging
▫Platform
▫Hoist
▫All parts are present, in proper working order, and are not damaged.
▫Bolts, nuts, and clamps are well secured.
▫Ensure the hoist is secured to the stirrup with SAE Grade 5 fasteners and lock nuts that are properly installed.
• In a dirty environment that contains epoxy, paint, cement, sand blast residue, or corrosive material, inspect the
operation of the overspeed brake several times a day. Protective hoist covers are recommended. Contact your
supplier.
Test the Overspeed Brake
1. While powering the hoist UP and DOWN
approximately 3 feet (1 meter), look through the
window into the overspeed compartment to see
whethertheywheelisturning.

2. Dereeve the wire rope.
3. Re-insert the wire rope about 12" (30 cm) into the
hoist.
4. Holdingthewireropermly,pullitoutquickly.
If the brake is working correctly, it will grab and
hold the wire rope in less than 4" (10 cm).
The red indicator lighton the front of the hoist
will light when the brake is activated.
5. Reset the overspeed brake by turning the
overspeed brake reset knobclockwise.
6. Repeat this test at least 3 times. If the brake does
not work correctly every time, DO NOT USE
THE HOIST. Return the hoist to your supplier.
Test the Overspeed Brake Test Button
• Push the UP operation button on the remote pendant and raise the platform approximately 3 feet (1 meter).
• While pushing the DOWN operation button on the remote pendant, push in the overspeed brake test button.
• The platform should stop immediately. WARNING!If the hoist does not immediately stop the platform when the
overspeed brake test buttonis pushed, this indicates the motor is out of phase. Stop pushing both buttons and
CORRECT THE PROBLEM BEFORE THE HOIST IS PUT IN SERVICE.
• Reset the overspeed brake by turning the overspeed brake reset knobclockwise.
Test the Emergency Stop Button
• While running the hoist in either direction, press the emergency stop button on the remote.
• Once the emergency stop button has been pressed, the hoist should not move at all.
• Twist to reset the emergency stop button.
Test the Controlled Descent
• Raise the platform approximately 3 feet (1 meter).
• Disconnect the power supply cable.
• Pull up the controlled descent leverCAREFULLY, to make sure the hoist does not overspeed. The platform
should descend at a slow, controlled speed.
WARNING! If the overspeed brake trips while testing the controlled descent, the controlled descent system is not
working properly and THE HOIST SHOULD NOT BE USED.
