Adjust Lip Latch & Lip Actuator Spring Tension (continued)
ADJUSTMENTS
The lip latch and lip actuator spring tension
are set at the factory and should not require
additional adjustment unless parts have been
replaced.
Unlike mechanical levelers, the lip will not
immediately begin to fold as the platform returns to
the stored position.
After the platform is fully raised, and the lip extends,
the lip latch is designed to hold the lip in the
extended position until the platform drifts down to the
below dock position.
The lip will automatically fold when the platform is
resting on the safety legs in the below dock position.
If the lip extends fully, but does not remain extended,
check proper engagement of the lip latch before
adjusting the lip latch spring.
If the lip does not extend fully, check air bellows
and lines for possible leaks before adjusting the lip
actuator spring.
Lip Latch Spring Tension
Note: Use two-turn increments when adjusting
lip assist spring. Check lip operation after each
adjustment. Repeat until proper operation is
obtained.
Adjust lip latch spring tension as follows:
1. Loosen jam nut on ( A ).
2. To increase spring tension, turn adjustment nut
on ( A ) clockwise.
3. To decrease spring tension, turn adjustment nut
on ( A ) counterclockwise.
4. Tighten jam nut ( A ).
5. Recheck operation of platform and lip. Readjust lip
latch spring tension as needed.
Lip Actuator Spring Tension
Note: Use two-turn increments when adjusting
lip assist spring. Check lip operation after each
adjustment. Repeat until proper operation is
obtained.
Adjust lip actuator spring tension as follows:
1. Loosen jam nut ( B ).
2. To increase spring tension, turn nut ( B ) clockwise.
3. To decrease spring tension, turn nut ( B )
counterclockwise.
4. Tighten jam nut ( B ).
5. Recheck operation of platform and lip. Readjust lip
actuator spring tension as needed.
