SECTION IV
MAINTENANCE / SERVICE
(14) If R.H. seat weldment (1) is too high in relation
to L.H. seat weldment (2), open valve (3), and
press SEAT DOWN button on hand control to
lower R.H. seat weldment.
If R.H. seat weldment (1) is too low in relation to
L.H. seat weldment (2), open valve (3), and
press SEAT UP button on hand control to raise
R.H. seat weldment.
(15) Repeat steps 13 and 14 until R.H. seat weld-
ment (1) is even with L.H. seat weldment (2).
(16) If opened in step 14, use a socket and exten-
sion to close valve (3). Tighten valve (3) to 11 -
12.5 ft-lbs (15 - 17 N•m).
(17) If removed, install leg section on table top.
(18) Perform calibration of return to level / neutral
position (Refer to para 4.3).
4.7 Column Cylinder Slave Line
Volume Adjustment
A. Volume Adjustment
(1) Using hand control, press TABLE UP button to
extend column assembly as high as it will go.
See Figure 4-7.
DANGER
Tilt table sideways until weight of table
just starts to go "over center". Tilting
table too far will put full weight of table on assis-
tant. Table is very heavy and could cause serious
back injury or table could get away from assis-
tant, causing serious personal injury or damage
to table.
NOTE
A tool for tipping table on side is available. See
Table 1-2. Special Tools.
(2) With help of an assistant, tilt table toward left
until valve (1, Figure 4-7 ) can be accessed.
(3) Using a socket and extension, unscrew valve
(1) approximately 1/2 turn, opening it.
(4) Lower table back onto floor.
(5) Using hand control, press TABLE DOWN button
to lower column assembly downward as far as it
will go.
(6) Using hand control, press TABLE UP button to
extend column assembly upward as far as it will
go.
CAUTION
Do not lower column assembly more than
1/16 in. (1.6 mm). Lowering column
assembly more than 1/16 in. (1.6 mm) will reduce the
maximum height capability of table. Not lowering
column assembly at all leaves too much oil in slave
line, resulting in over-compressed oil in slave line
when column assembly is fully extended. Then, when
column assembly is lowered, the over-compressed oil
in slave line causes column cylinder to "jump"
downward, making a noticeable noise and a notice-
able jolting movement.
