Quiet-Ride Adjustment Instructions
Adjustable Quiet-Ride Guided Stop Blocks and fixed
rubber bumpers mounted at key locations aid in
eliminating or reducing potential rattles. Improper
1. Vertical Upright Deflection:
Lift towers (vertical uprights)
must
be parallel
(aligned) with the platform side plates. If the lift
towers are deflected in (toward platform), or the
towers move (vibrate) “side-to-side” during vehicle
movement, metal-to-metal contact can occur
between the parallel arm pivot pins and the platform
side plates (particularly opposite-pump side).
Positioning of and tightening of base plate mounting
bolts substantially affects vertical upright deflection
and “side-to-side” movement of towers. Tighten
base plate mounting bolts as detailed in Step 2 of
the Lift Installation Instructions (see page 16).
installation procedures can result in potential rattles
also. If lift rattles occur, review the details in this
section for possible source and remedy.
3. Handrail Rubber Bumpers:
Vibration can occur between the handrails and
the vertical arms. This vibration is eliminated with
the rubber bumper mounted on each handrail
(factory-equipped). The rubber bumper is
positioned such that it contacts the vertical arm
when the lift is in the fully folded (stowed) position
and prevents direct metal-to-metal contact. Refer
to the part numbers at the right for replacements.

2. Quiet-Ride Guided Stow Blocks:
Quiet-Ride guided stow blocks are mounted to
both top parallel arms to reduce "in-out" platform
vibration. The platform side plates make contact
with (nest in) the stow blocks. See Photo J at
right and Photo A on page 16. The stow block
mounting brackets have oval mounting slots
provided for “in-out” adjustment.
Fold the platform in fully (stowed). Grip the top of
the platform and attempt to move the platform "in-
and-out." The platform side plates should be
making contact with (nesting in) the stow blocks
so that the platform does not rock (move “in-and-
out”). If the platform can be easily moved in and
out, reposition the adjustable stow block
bracket(s) as needed.
Mark the position of the bracket(s). Unfold the
platform, loosen mounting hardware and reposi-
tion (shift) location of these brackets as needed to
result in a tighter fit (positive contact) between the
stop blocks and the platform side plates.
Tighten
the
mounting hardware securely
