4. Elevate the machine until the lower tension mem-
ber clears the limit switch lever. Set the LO
RANGE potentiometer so that the machine will
travel 6.1 m (20 ft.) in 27 to 28 at full controller
deflection.
Note: The machine should be running full speed
before crossing the starting line, and should
run perfectly straight through the course.
5. Repeat the speed trials for verification and read-
just as necessary.

1. Check tires for proper pressure.
2. Place the work platform on a level surface with
the front and rear axles parallel (on the same
plane).
3. Adjust the switch so it is centered in the front axle
actuator linkage. When centered, the switch will
close the circuit.
4. Test the switch function by positioning the front
axle off-center and raising the platform 2.21-2.26
m (87-89 in.) above the ground. The work plat-
form should not drive. Retest with axle off-center
in the other position.

Cushion Down Limit Switch
(Figure 3-11)
The cushion down limit switch is a mercury switch
that provides power to energize the cushion valve
during the last 30 cm (12 in.) of platform lowering.
1. Raise the platform 30 cm (12 in.) from its’ fully
lowered position.
2. Disconnect the wires at the mercury switch and
connect an ohmmeter or continuity tester.
3. Rotate the switch until it just closes. If necessary,
tighten the locknut that mounts the switch.
4. Raise and lower the platform to verify the adjust-
ment.
5. Disconnect ohmmeter and reconnect wires.
6. Lower platform.
