NOTE: After the OUT switch is pressed three times, there is a time period of 5 minutes during
which the programming switch is enabled. Programming will be disabled if any other switch
is used during this period.
5) Verify that programmed intermediate position is correct by stowing platform, then deploying
and raising it to intermediate height.
NOTE: It is acceptable for the intermediate position to vary +/- ½ inch from the programmed height.
5. ANTI-STOW PRESSURE SWITCH ADJUSTMENT
An adjustable, pressure sensing, electrical switch is installed in the hydraulic line that is connected to
the hydraulic cylinder. The switch will detect the presence of a 75 lb. load, or greater, on the deployed
platform. Correct adjustment of anti-stow switch inhibits horizontal movement of loaded platform,
providing an element of safety for lift users.
CHECK:
l. Refer to Figure 2-6. The pressure switch adjusting screw is located at the top of the body,
between the two lead wires. There is a locking set-screw above the adjusting screw, which must
be removed to carry out pressure switch adjustments.
m. Apply power to lift and deploy platform.
n. Lower platform to ground, and place a 75 lb. weight in center of platform.
o. Press /IN button plus red STO-GARD LOCKOUT button until platform reaches STOW height.
Platform should stop at stow height and not enter enclosure. Proceed to next step if platform at-
tempts to enter enclosure.
ADJUST:
a. Remove locking set-screw (requires hex key) and turn adjusting screw 1/8 turn CCW to increase
sensitivity.
b. Repeat above steps until the 75 lb. weight inhibits stowing of platform. Repeat test from floor
height; platform should stop at stow height and not enter enclosure.
c. Remove test weight and then check platform stow function from ground height and from floor
height. Platform should stow properly from either level. Replace locking set-screw.
NOTE: Normal platform operation may not occur if pressure switch adjustment is too sensitive (inhibits
stow function when a weight that is significantly less than 75 lb. is present). Turn adjusting
screw CW to decrease sensitivity.
Also, erratic platform movement may occur if setting of pressure switch is marginal. Correct this
by turning adjusting screw 1/16 turn in appropriate direction.
6. ROLLSTOP ADJUSTMENT
Correct operation of the outer rollstop is essential to user safety. The rollstop is adjusted at the factory
and should not require further adjustment after delivery and installation. Rollstop adjustment is not
affected by the configuration of the installation. If there is any doubt about the rollstop operation, refer
to “Rollstop Maintenance” in the “Travelling Frame” section of chapter four.
