* In the FREE CHAIN position the hand lever does not engage the ratchet gear. The hand lever freewheels until the
selector lever is shifted to the UP or DOWN position. In the FREE CHAIN position chain may be raised (hauled in) by
grasping the anchor side of load chain and pulling or by turning the free knob in the clockwise direction. In the FREE
CHAIN position chain may be lowered (payed out) by grasping the hook side of load chain and pulling or by turning the
free knob in the counterclockwise direction.
Positioning Unloaded Hook (FREE CHAIN Position)
• To prevent injury or property damage always remove load from hoist before shifting selector lever to the FREE
CHAIN position and/or rotating free knob to the RED position.
1. Set the selector lever to FREE CHAIN (center) position.
2. Grasp the anchor side of load chain. Rotate the free knob counterclockwise until all RED is viewed in the indicator
window of the indicator plate.
3. Pull hook side of load chain to lower the hook to the desired location. Connect hook to load. Pull the anchor side of
load chain until chain slack is removed.
Lifting Load (UP Position - Haul In)
The following procedure assumes the hoist is in FREE CHAIN mode with all RED showing in the indicator window. The
hook is attached to a load, but the hoist is not supporting the load.
• ALWAYS ensure that only all GREEN is viewed in the indicator window of the indicator plate whenever
shifting the selector lever to the FREE CHAIN position to prevent dropping load. This includes shifting from
the UP to DOWN, or DOWN to UP positions as the selector lever must pass through the FREE CHAIN position.
1. Place selector lever in the UP position. Grasp the hook side of load chain.
2. Rotate the free knob clockwise until all GREEN is viewed in the indicator window of the indicator plate.
3. Pull anchor end of load chain until slack is removed.
4. Rotate (ratchet) hand lever in the clockwise direction to raise (haul in) load.
• Ratchet may not engage and raise (haul in) load until all chain slack is removed and hoist is supporting load
weight. If hand lever movement does not produce lifting, apply tension to the anchor side of load chain while
ratcheting until slack is removed and the hoist begins lifting the load.
Lowering Load (DOWN Position - Pay Out)
The following procedure assumes the hoist selector lever is in the UP position and GREEN is showing in the indicator
window. The hoist is holding a load and the operator wants to lower (pay out) the load:
1. Place selector lever in the DOWN position.
2. Rotate (ratchet) hand lever in the counterclockwise direction to lower (pay out) load.
• To prevent injury or property damage always lower loads until the load chain becomes slack before shifting to
the FREE CHAIN position and/or rotating the free knob to the RED position.
SL Hoist Operation
Positioning Unloaded Hook (Neutral Position)
• Do not support or hang loads from load chain free end. Brake may not hold load or operate correctly.
In the NEUTRAL position the hand lever does not engage the ratchet gear. The hand lever free-wheels until the selector
lever is shifted to the UP or Down position.
1. Set the selector lever to NEUTRAL (center) position.
2. Turn free chain knob counterclockwise.
3. Grasp and pull one side of the load chain or turn free knob until desired hook position is achieved.
4. Connect hook to load. Pull the anchor side of load chain or turn free knob until chain slack is removed.
