f. Lock Adjustments.
(1) Transverse and compression lock adjustment. The transverse lock is
located inside the table, while the compression lock is located in the table tower. The
compression lock can be accessed from the top and bottom of the tower without
removing covers.
(a) If necessary, turn off the power and remove the table top.
(b) The transverse and compression locks are held in adjustment on
two threaded studs by means of nuts and lock washers. Adjustment consists of moving
the lock in or out along the length of the studs by the nuts.
(c) Engage the lock and attempt to move the corresponding part. It
should take a minimum of 20 pounds of force to move. Locks should not make a
"banging" sound when energized. If there is a "banging" sound, move the lock closer to
the corresponding part by disengaging the lock and turning the interior nuts
approximately one-half turn clockwise. Do the same with the outer nuts. Repeat this
procedure as many times as necessary until there is no longer a "banging" sound.
(2)
Longitudinal and grid lock adjustment.
(a) If necessary, turn off the power and remove the table top.
(b) The longitudinal and grid locks are held in adjustment on two
threaded studs by means of springs secured with washers and cotter pins. Adjustment
consists of moving the lock in or out, by tightening or loosening the studs with a hex key
wrench.
(c) Engage the lock and attempt to move the corresponding part. It
should take a minimum of 20 pounds of force. Locks should not make a "banging"
sound when energized. If there is a "banging" sound, disengage the lock and move it
closer to the corresponding part by turning the hex-socket studs clockwise
approximately one-half turn. Repeat the process as many times as necessary until
there is no longer a "banging" sound.
g. Tilt Drive Chain Tension Adjustment.
(1)
If necessary, remove the drive-mechanism cover at the foot end of the
table body.
(2)
Use a torque wrench to apply 11 foot-pounds to the tension screw.
(3)
Replace all covers on the table.
