(61 cm) and then run the hook into the upper limit with
(UP) control held depressed.
13. Fine adjustment of the upper limit setting may be
obtained by inverting the stationary guide plate in Step
10. (Not available with the rotatable guide plate.) The
offset on the plate gives adjustments equivalent to 1/2
notch, see Table 6 for the “Hook Travel Per Notch of
Limit Switch Nut”. When inverting the plate, it may be
necessary to use the notch adjacent to the one used in
the preliminary setting.

5. Refer toTable 6 -The“B”dimensions given are the
minimum length of loose end chain left on the non-load

6. Reconnect hoist to power supply.
7. Run hook to the desired lower position, cautiously
operating the hoist without a load.
8. Disconnect hoist from power supply.
9. Moving one travel nut toward the other increases hook
travel and away from the other decreases hook travel.
Now, turn the nut nearest the switch indicated as the
“LOWER LIMIT SWITCH” until it just breaks the limit
switch contacts, cautious not to allow the movement of
the other travel nut if previously set. An audible click will
be heard as the switch opens. Continue to rotate the nut
toward the switch an additional one full tooth.
10. Securely reposition the guide plate in the slot.
11. Reconnect hoist to power supply and check the stopping
point of hook by fi rst raising the hook about 2 feet (61 cm)
then lower the hook by jogging cautiously until the lower
limit switch stops downward motion. The stopping point
of the hook should be the desired lower position, if not
repeat the above instructions.
12. Double check setting by raising the hook about 2 feet
(61 cm) and then run the hook into the lower limit with
(DOWN) control held depressed.
13. Fine adjustment of the lower limit setting may be obtained
by inverting the stationary guide plate in Step 10. (Not
available with the rotatable guide plate). The plate offset
on the plate gives adjustments equivalent to 1/2 notch,
see Table 6 for the “Hook Travel per Notch of Limit Switch
Nut”. When inverting the plate, it may be necessary to
use the notch adjacent to the one used in the preliminary
setting.
