NEVER WORK UNDER AN ELEVATED PLATFORM UNTIL IT HAS BEEN
RESTRAINED FROM MOVEMENT WITH SAFETY PROPS, BLOCKING, OR
OVERHEAD SLING.
1.
Install flange bearings into the frame holes with
the flange side facing inside of frame against Pot-
Hole bar hinge.
2.
PHP Bearing Adjustment - If reassembling or
replacing PHP components, PHP bars may not
store at same height due to manufacturing toler-
ances of parts. Adjustment may be needed after
assembly:
a.
Completely lower the platform and compress
the actuator assembly to raise the PHP bars,
check to see If only one PHP bar is raised
against the frame.
b.
If Yes, elevate the platform to release the
actuator assembly and deploy the PHP bars.
The actuator bearing bracket (2) allows for
some side to side adjustment, mark the cur-
rent position of the actuator bearing bracket
(2) on the frame.
c.
Loosen and move the actuator bearing
bracket slightly towards the PHP bar that will
not raise completely, and re-tighten bracket
down.
d.
Compress the actuator assembly again to
stow the PHP bars and check bar ground
clearance. Repeat steps (a) through (c) above
until both PHP bars achieve maximum
ground clearance. (See Ground Clearance -
Table 1-1, “Operating Specifications,” on
page 1-1).
3.
Do not tighten limit switch mounting screws
beyond 2.58 ft lbs. (3.5 Nm).
4.
PHP Limit Switch Adjustment - When the plat-
form is raised and PHP bars fully DOWN, adjust
the switch until it lightly contacts the ramp on the
lower actuator.
