required adjustments made to ensure
conformance with the requirements.
• If, for any reason after this procedure is
complete, the right leg cylinder is replaced, or
the right leg cylinder pivot block shims are
changed, the Leg Return-to-Level and Leg
Full-Up positions must be rechecked and any
required adjustments made to ensure
conformance with the requirements.
• See Figure 7-2 and Figure 7-3 for information
and a picture of the environment and
hardware dealt with in this procedure.
Figure 7-2. Leg Level Position Adjustment
Procedure for Return-To-Level
1. Initial Leg Full-Up Angle Check:
a. Disconnect leg section Return-to-Level wiring.
b. Actuate leg up until motion stops.
c. Measure angle leg section makes with seat
section. Ensure it is 80 ± 1°. Record angle.
d. If angle is not 80 ± 1°, initial leg adjustment is
not correct and leg cylinder pivot block shims
must be reassessed - see

e. Reconnect leg section Return-to-Level wiring.
2. Leg Return-to-Level Position Adjustment:
NOTE: Refer to Figure 7-2 for a flow chart for this
adjustment procedure.
a. Lower leg approximately 10° below seat section
angle. Actuate Return-to-Level. When all
motion has stopped, note angle leg section
makes with seat section.
NOTE: If during the Return-to-Level function the
leg does not come to rest but oscillates up and down
from the horizontal position, reposition the
adjustable switch away from the cylinder rod.
b. Raise leg section approximately 10° above seat
section angle. Actuate Return-to-Level. When
all motion has stopped, note angle leg section
makes with seat section.
c. If angles measured in Step 1 are within
specification, Leg Level Position Adjustment is
complete. Proceed Leg Full-Up Position
Adjustment.
d. If angles measured in Steps 2a and 2b are not
within specification and their difference is less
than 3°, axial adjustment of cam shaft position
is required. Proceed as follows:
• Loosen screw attaching cam shaft to bracket,
slide shaft fore or aft, and retighten screw.
