6.4 TABLE OBSERVATION

1. Check entire table for proper fit and finish of all

exposed parts. Check for any burrs, sharp edges or
corners to which users could be exposed. Correct as
necessary.

2. Check base/column shrouds for damage and

proper movement/engagement.

3. Using a Clark socket, ensure socket slides freely

over each side rail and that rivet stops and gravity
locks prevent socket from being removed. Ensure
each gravity lock swings freely.

4. Flip foot pump pedal up and down several times to

ensure it pivots smoothly and stays in position.

5. Articulate headrest throughout its range (+90° to

-90°). Ensure ratchet action is normal and release
handle operation is smooth throughout range.

6. Raise kidney bridge to maximum height (top

surface of bridge should be at least 3-7/8" [98 mm]
from top surface of leveled back section). Ensure
ratchet action is smooth and normal throughout.
Flip handle into and out of its stowed position
several times, ensure detent retains handle in
stowed position.

6.5 TABLE MOBILITY

NOTE: The following tests are to be done with the floor
locks disengaged, with the tabletop horizontal and at
maximum elevation, and on a smooth level surface.

1. Move table forward, backward, left and right: 3"

(914 mm) minimum in each direction. Ensure
casters operate smoothly and without unusual
noise.

2. Move table longitudinally, with headrest leading,

until casters are aligned for movement in that
direction. Attach a spring scale to end of leg section
on table centerline. Slowly push table straight

ahead. Gauge reading should be less than 35 lb
(16 kg).

3. With table in same alignment, slowly push at right

angles to table centerline, at outboard end of left
side rail on table headrest. Gauge reading should
be less than 20 lbs (9 kg).

6.6 FLOOR LOCK ASSEMBLY

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). If adjustment is
necessary, refer to

6.7 TABLE ARTICULATION

1. Articulate each table function through entire range

and ensure there are no unusual noises, speed
variations or other performance problems. Table
speed and range of movement should fall within
parameters shown in

Table 6-1

2. Actuate RAISE function for at least 30 seconds. This

causes pump to develop maximum pressure and
relief valve to be fully employed. There should be
no chattering, squealing or other unusual noises.

3. Refer to

Table 6-2

(for electric table) and

Table 6-3

(for battery-powered table) and articulate table
through various functions using conditions
described.

NOTE: If a battery-operated table, the base shroud
must be removed for the last three conditions - see

Step 4

4. Remove table column and base shrouds as

described in

5. Thoroughly examine table assembly for evidence of

any hydraulic leaks, mechanical wear, electrical
wire abrasion or any other degradation. Articulate
each table function again through entire range and
ensure there are no unusual noises, speed variations
or other performance problems.
