Platform Angle Adjustment
Improper microswitch
adjustment may
result in serious
bodily injury and/or
property damage.
Automatic Floor Level Positioning: GVL936
Series lifts feature automatic floor level positioning.
This feature eliminates the need for the lift operator
to position and stop the platform at vehicle floor
level when unfolding the platform from the stowed
position and when raising the platform from ground
level.
Floor Level Adjustments: Tower 1 (Unfold) and
Tower 2 (Up) microswitches control platform and
bridge plate positioning. Ensure floor level adjust-
ments are correct as outlined on page 7. Adjust
microswitches as needed only.
Floor Level Guidelines: When adjusting micro-
switches, bridge plate positioning and platform stop
block positioning must be viewed. A combination of
adjustments may be required to achieve a proper
balance. See Bridge Plate Positioning and Stop
Blocks below.
Stop Blocks: The platform stop blocks
(one per side) must be making full contact
with the vertical arms when the platform is at
floor level. See Photo A. Improper adjust-
ment of screw positioning can result in
lift damage.
Bridge Plate Positioning: The bridge
plate should rest solidly on the base plate.
There should be a smooth (level) transition
between the platform, bridge plate and the
base plate. Refer to Photos B and C.

Platform Angle Adjustments: Check platform
angle as outlined on page 5 when adjusting micro-
switches.
Adjustment Verification: Following the outlined
adjustment procedures, check floor level position
from stow position and from below floor level posi-
tion. The platform must stop automatically at floor
level when unfolding from stow position and when
raising from below floor level position. From the
stowed position, press the UNFOLD switch and hold
until the platform stops
at floor level. Once
stopped, ensure the
lift will fold when the
pendant FOLD switch
is pressed. Adjust the
switches as needed
per the guidelines in
Figure E.
