d. Speed Controls
The speed controls restrict the volume of oil return-
ing back to the reservoir thereby controlling the
speed of each control function.
All four-way mini-valves, have two speed controls
located in the ends of each valve body. All three-
way mini-valves have only one speed control.
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. See figure 1-20.
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 oppo-
site direction by opening or closing the speed
control. Approximate operating times are as fol-
lows:
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 1-19.
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 2 -925PSI
Dn 65KG/CM 2 -925PSI

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.
