gland, remove the wire from Terminal
2.
Move the hoist motor in small steps by
tapping the 12VDC wire to Terminal 2
until the motor stops driving.
Do not let the safety clamp press into
the packing gland.
7.1.8 When the hoist stops, there must be at
least 1.25cm (.5inches) between the safety
clamp and the packing gland.
The hoist should automatically stop
lowering before it reaches bottom.
If the safety clamp does not stop, or if
it is less than 1.25cm (.5 inches) above
the packing gland, you must reposition
the top hoist clamp on the lead screw.
