19.1.5 When performing the next steps, do not let
the hoist descend so far that the motor continues
to run after it touches the lower stop.
This could damage the hoist assembly.
19.1.6 Make sure leads from Terminal 2 and Ter-
minal 27 are not touching any other wire.
Turn on the hoist and console, and push down the
hoist switch.
Now there is +12VDC on the wire you pulled from
Terminal 2, and hoist motor voltage.
19.1.7 When voltage is applied to the hoist, check
the hoist down light on the console. It should be off.
Move the hoist motor in small steps by tapping the
12VDC wire to Terminal 2 until the motor stops
driving.
Do not let the tube clamp press into the shock tube.
19.1.8 When the hoist stops, there must be at least
1.25 cm (.5 inch) between the tube clamp and
packing gland.
19.1.9 If the safety clamp does not stop, or if it is
less than 1.25 cm (.5 inches) above the packing
gland, you must reposition the bottom limit switch.
Check the "hoist down" light on the console. The
red light should be on.
