NOTE: A change in position of the shaft of 0.020"
(0.51 mm) results in an angle change of about 1°.
• If leg section stopped too high, slide cam shaft
toward cylinder rod.
• If leg section stopped too low, slide cam shaft
away from cylinder rod.
• Repeat

Adjustment.
3. Leg Full-Up Position Adjustment:
Ensure Return-to-Level wiring is properly
connected. Actuate leg up until motion stops.
Measure angle leg section makes with seat section.

4. Requirement Specifications:
a. Return-to-Level Angles - After actuation of Leg
Return-to-Level, for both leg section initially
above and below seat section, angle of leg
section, measured with respect to seat section,
shall be 0 + 2°.
b. Leg-Up Angle - When leg is actuated fully up,
angle of leg section measured with respect to
seat section shall be 80 ± 1° (angle must be at
least 1° less than maximum angle permitted by
mechanical elements).
7.11 FLOOR LOCK LINKAGE AND
SWITCH ADJUSTMENT
See Figure 7-4.
1. Back off floor lock limit switch actuation screw to
prevent damage to switch (if applicable).
2. Press FLOOR LOCK function button until floor lock
cylinders are fully extended.
3. Turn cylinder rod out of clevis until gap between
clevis and floor lock housing is 1/8 ± 1/32" (3.2 ±
0.8 mm)
NOTE: The linkage should be just over center.
4. Adjust floor lock switch actuator screw so switch is
just actuated when floor locks are locked (if
applicable).
5. Apply Loctite #290 (R5300-540) liberally to both
actuator screws and cylinder rods where they enter
the clevis.

7.12 FLOOR LOCK ADJUSTMENT
1. With table on a level floor, engage floor locks.
2. Check distance between each caster and floor, it
should be 1/4 ± 1/32" (6 ± 0.8 mm).
3. If necessary, adjust floor locks as follows:
a. Unlock floor locks and turn each foot onto its
shaft until foot does not make contact with floor
when floor locks are engaged.
b. Engage floor locks. Unscrew each foot from its
shaft until it just makes contact with floor.
c. Unlock loor locks and unscrew each foot an
additional 4-1/2 turns.
d. Verify distance between caster and floor is 1/4
± 1/32" (6 ± 0.8 mm) with floor locks engaged.
7.13 SEAT SECTION LIMIT SWITCH
ADJUSTMENT
1. With tabletop sections horizontal, manually
depress limit switch LS3, mounted to saddle under
seat section. Attempt to actuate FLEX. Pump should
