c. Pressure Relief Valve
The pressure relief valve is adjusted by turning the
adjustment nut until the desired pressure is reached.
To adjust:
1. Remove the blind cap and attach a hydraulic
pressure gauge to the main oil galley using a 6mm
plumbing bolt. See figure 1-20.
1-3. Hydraulic Adjustments
a. Fluid Level.
The fluid level should be approximately 1/2" below
the filler hole or gasket surface. If additional fluid is
needed, remove the filler vent cap with a phillips
screwdriver and add fluid through this opening
using a funnel. See figure 1-19.
NOTE
The elevation cylinder should be com-
pletely down and all the other control
functions in their neutral position when
checking oil level.
Figure 1-19.
The type of oil that should be used is Mobil DTE #25
or equivalent. This is a very high quality hydraulic
oil. The table requires approximately two quarts of
oil to operate properly.
b. Bleeding The Hydraulic System
To purge the air from the hydraulic system, operate
each function back and forth at least two or three
times.
NOTE
Whenever a hydraulic line or component
is replaced, bleed the air out of the lines
using the pump pressure before mak-
ing the final connection. Then operate
the function until it stalls in both direc-
tions.

2. Raise the table top until the piston reaches the
end of its stroke and stalls. Observe reading on
pressure gauge and turn the adjustment nut (clock-
wise to increase oil pressure, counterclockwise to
decrease) until desired reading is obtained. Pressure
should be 80KG/CM† -1138 PSI.
