Improper microswitch
adjustment may
result in serious
bodily injury and/or
property damage.
WARNING
Bump
When adjusting microswitches, stop block
positioning and bridge plate positioning must
be viewed. A combination of adjustments may
be required to achieve a proper balance.
Adjust Unfold/Down and Up/Fold mi-
croswitches as outlined on page 37.
Stop Blocks:
The stop blocks
must make full contact
with
the inboard vertical edge of the vertical arms
when the platform ia at floor level (see Photo
D).
Stop blocks must be properly posi-
tioned
as detailed on page 28.
Improper
stop block positioning can result in lift
damage
.
Bridge Plate Positioning:
Photo H shows the lift platform positioned too
high. An incorrect Unfold/Down microswitch
setting can prevent the platform from unfolding
fully during the Unfold cycle. Or, the Up/Fold
microswitch may be adjusted improperly,
allowing the platform to raise above floor level
during the Up cycle. The bridge plate overlaps
the base plate causing a bump (uneven
surface).
The bridge plate should be positioned so that
the inboard edge of bridge plate rests solidly
on base plate as shown in Photo I when at
floor level. There should be a smooth (level)
transition between the platform, bridge plate
and the base plate (shown in Photo I).
Photo J depicts the platform positioned too
low. An incorrect Up/Fold microswitch setting
can stop the platform from reaching the fully
riased position during the Up cycle. Or, the
Unfold/Down microswitch may be adjusted
improperly allowing the platform to unfold to a
position below floor level during the Unfold
cycle. The bridgeplate does not make solid
contact with the base plate.
