LIP ASSIST SPRING ADJUSTMENT
1. Proper adjustment of the lip assist spring is defined
as “the condition of maximum spring compression
that permits the lip to fall of its own weight to the
fully pendant position.”
2. To adjust the lip assist spring, release the lock nut
and advance the adjustment nut clockwise to
produce maximum compression on the spring while
still allowing the lip to fall.
3. Back off the adjustment nut until the lip, when
dropped from the fully extended position, barely
overcomes the spring tension and falls to the
pendant position. Tighten the lock nut to secure the
adjustment.
MAIN LIFT SPRING ADJUSTMENT
GOAL - To MINIMIZE the spring force (and ultimately
the walkdown) while still reliably latching the lip and
raising from below dock.
Note:Adjustments should be made in small
increments equally to each adjustment nut. (i.e. 1/2
turn at a time on both adjustment nuts)
With the leveler positioned approximately 2" above
the stored position, raise the platform and allow the
lip to extend and latch. If the lip does NOT latch:
• Due to a lack of spring energy - Increase the spring
tension on the lift springs by turning each of the
nuts on the spring pull bar weldment(s) clockwise in
equal, full turn increments.
• Due to the platform raising violently - Decrease the
spring tension on the lift springs by turning each of
the nuts on the spring pull bar weldment(s) counter-
clockwise in equal, full turn increments.
Verify that the platform will raise from the fully below
dock position Do NOT allow the lip to extend! If
the platform does NOT raise:
• Increase the spring tension on the lift springs by
turning each of the nuts on the spring pull bar
weldment(s) clockwise in equal, full turn increments.
Make sure to position the maintenance support
when making the lip assist spring adjustment.
NEVER REMOVE adjustment nuts from main spring
adjustment rod. Serious injury or death will occur.
• Make sure to insert the maintenance support
when making the main extension spring
adjustment.
• Refer to operating instructions - follow all
CAUTIONS and WARNINGS prior to activating
your dock leveler.
