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 Defelection:
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).
2. Quiet-Ride Guided Stop Blocks:
Quiet-Ride guided stop blocks are mounted to both
platform side plates to reduce "in-out" platform vibration.
The guided stop blocks make contact with handrails.
Fold the platform in fully (stowed). Grip the top of the
platform and attempt to move the platform "in-and-out."
The Quiet-Ride guided stop block should be contacting
the handrail so that the platform does not rock (move "in-
and-out").
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.
4. Roll Stop Bumpers:
Vibration can occur between the roll stop activation
feet and the platform. This vibration is eliminated with
the rubber bumpers mounted to the bottom of the
inboard platform section (one on both sides). The roll
stop activation feet contact the rubber bumpers when
the lift folds fully (stows) and prevents direct metal-to-
metal contact. Refer to the part number at the right
for replacements.
installation procedures can result in potential rattles
also. If lift rattles occur, review the details in this
section for possible source(s) and remedies.
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).
