2. Turn cylinder rod into clevis to increase DOWN

articulation and out to decrease articulation. A 1°
change is equal to 1/10 revolution of rod in clevis.

3. Back articulation away from maximum DOWN

position approximately 1°. Make necessary
adjustments based on

Steps 1 and 2

to give a

maximum DOWN position of 25°.

4. Repeat

Step 1

. Measured angles must be 25 ± 1°,

and amount of racking must be 0.5° or less. Repeat

Step 2

if necessary.

5. Articulate back section to full UP position. Measure

and record angular position of both sides. Amount
of racking must be 0.5° or less; if not, adjust to
equalize racking in maximum UP and DOWN
positions.

6. Apply Locktite 290 to relock adjustments.

7.8 SEAT SECTION ADJUSTMENT

Adjust tabletop seat section as follows:

1. Move seat section to full DOWN position. Measure

and record angle.

2. Turn cylinder rod into knuckle to increase DOWN

articulation, and out of knuckle to decrease DOWN
articulation.

NOTE: A 1° degree change is equal to 1/18 revolution of
the rod and knuckle.

3. To ease adjustment, raise seat section to horizontal

or above. Loosen jam nut. Make necessary
adjustment based on

Steps 1 and 2

to give a

maximum DOWN position of 25°. Tighten jam nut
against knuckle.

4. Repeat

Step 1

. Measured angle must be 25 ± 1°.

Repeat

Steps 2 and 3

if necessary.

7.9 SIDE TILT CYLINDER

ADJUSTMENT

Adjust side tilt hydraulic cylinder as follows:

1. Level table.
2. Move table to full RIGHT SIDE TILT position. Using

digital protractor, measure angle of right tilt.

3. If tilt angle is not 18 ± 2°, adjust angle as follows:

Remove clevis locking plate by removing two
socket-head screws securing clevis locking
plate.

Briefly run tilt and place a block, such as a large
screwdriver blade, behind mechanical lock
plunger on side tilt cylinder so mechanical lock
does not engage when tilt is stopped.

NOTE: With the locking plate removed, the shaft
may have a tendency to screw into or unscrew from
the clevis. If this occurs, rotate the shaft back to the
original position in the clevis when the tilt is stopped.

4. Move into right tilt but stop before full extension.

Adjust angle by rotating cylinder shaft.

5. Reinstall clevis locking plate using two socket-head

screws. Ensure cylinder rod flat is square with
machined step on clevis.

6. Remove mechanical lock block (screwdriver) by

running tilt while pulling block out.

7. Place table into full tilt and measure degree of tilt.

Angle must be 18 ± 2°. Readjust if necessary.

8. If angle is correct, remove socket-head screws

securing clevis lock plate. Apply Loctite 262 to
screws, reinstall and tighten screws ensuring
cylinder rod flat is square with machined step on
clevis.

7.10 LEG RETURN-TO-LEVEL AND LEG

FULL-UP ADJUSTMENT

Important:

For this procedure, note the following:

• The adjustment of the Leg Full-Up position is

affected by the adjustment of the Leg Return-
to-Level position. Therefore, the Leg Return-
to-Level procedure must precede the Leg
Full-Up procedure.

• If, for any reason after this procedure is

complete, the cam shaft is repositioned, both
the Leg Return-to-Level and Leg Full-Up
positions must be rechecked and any

CAUTION – POSSIBLE EQUIPMENT
DAMAGE:

Before articulating or making any

adjustments to the table, ensure no electrical
or hydraulic hoses are subjected to stress or
pinching.

WARNING – PERSONAL INJURY HAZARD:
The lock mechanism has a high spring
force and can cause severe pinching. Keep
fingers, etc. away from under the plunger
and blocking.

CAUTION – POSSIBLE EQUIPMENT
DAMAGE: Tilt articulation must be
activated while adjusting the cylinder rod
to release the brake mechanism. Failure to
do this destroys the cylinder.
