b. Release Switch Adjustment
A limit switch is mounted below one driveshaft support arm, and detects the position of the arm. It
is adjusted to change states when the pinion gears disengage.
NOTE: Refer to Electrical Controls section if replacement of switch is necessary.
CHECK:
1) Refer to LIFT SERVICE ACCESS section to deploy platform and open service access
panel.
2) Rotate either release shaft 90
o
in the direction indicated on adjacent decal, using manual
back-up pump handle. This disengages pinion gears from gear racks.
3) Refer to Figures 4-17 and 4-21. Listen to switch as release shaft is rotated. It should click
faintly (change state) when the driveshaft support arm contacts the switch roller (as shown
in figure). The change of state is also marked by the switch contact resistance becoming
infinite (open) when measured at pins four and five of the lifting frame harness.
ADJUST:
1) Loosen switch retaining screws, and slide switch downward on its bracket until switch roller
loses contact with arm. Slide switch upward until a faint click is heard (or resistance be-
comes infinite). Tighten screws.
2) Rotate release shaft to re-engage pinion gears. A faint click should be heard from switch as
it changes state.
NOTE: It is important to verify that switch states are different when gears are engaged and un-
engaged.
3) Raise service access panel, and install two retaining screws and lock-nuts at front edge of
panel.
