One speed control adjusts one direction of a
particular function and the opposite speed control
adjusts the other direction. They are adjustable by
using a small straight blade screwdriver and
turning the adjustment screw clockwise to de-
crease the speed and counterclockwise to
increase the speed. Refer to figure 1-21.
Figure 1-21.
Any control function should move in either direc-
tion at the same rate. If the rate of a certain function
is too slow, open the speed control slightly and
recheck. Use the second hand on a watch and time
a particular function. Match that time in the opposite
direction by opening or closing the speed control.
Approximate operating times are as follows:
Elevation Down 30 seconds
Lateral Tilt 7 seconds
Leg-Up 25 seconds
Leg-Down 15 seconds
Kidney Lift 7 seconds
Slide 20 seconds
A pressure gauge should be used to set the speed
of the back section, trendelenburg and flex control
functions.
To adjust:
1. Attach the pressure gauge onto the main oil
galley as shown in figure 1-20.
2. The gauge should read the following values
when operating the various control functions in
either direction. Turn the speed controls until
desired values are obtained.
Back Section Up 65KG/CM† 925PSI
Dn 65KG/CM† 925PSI
Trendelenburg Up 65KG/CM† 925PSI
Dn 65KG/CM† 925PSI
Flex 70KG/CM† 995PSI
Reflex 70KG/CM† 995PSI
NOTE
When adjusting Flex/Reflex speed con-
trols, set Reflex last.
Elevation - There is not a speed adjustment for
raising the table. The speed control will only affect
the rate of descent and it should equal the rate of
elevation.
