2.2.12 Installing the Elevation Limit Switch
Step 1.
Install the pivot plate to the hub tooling boss with supplied hardware.
Step 2.
Install the bracket on the elevation lug and attach the switch to the bracket so that it
lays flat.
CAUTION!
IT IS POSSIBLE TO INSTALL THIS BRACKET INCORRECTLY,
WHICH WILL CAUSE IMPROPER ALIGNMENT OF THE LIMIT
SWITCH. SEE FIGURE 25 FOR CORRECT POSITIONING.
Step 3.
Slip one stop collar onto the rod and tighten it close to the hub. After threading the
end of the stop rod through the limit switch arm, secure it with a retaining nut and
attach the stop rod to the pivot plate.
Step 4.
Slip the other collar over the rod near the end and tighten it.
Step 5.
Adjust the length of the switch arm until the rod rides without binding. Drive the jack
to its retracted and extended lengths and adjust the stop collars so that the switch is
tripped before the mechanical stop is reached
