Stand the machine up to the storage position. On the
bottom side, locate the two small valves. Remove the line
coming from the bottom of the right-hand valve and drain
into cup. (The gray collet must be depressed to release the
hose from the fitting.) This will drain the line that runs
to the transfer roller.

CHECKING THE PRESSURE:
On Serial Number
2371
and after, (or machines upgraded
to the pressure regulator tubing box), place the machine in
the operating position and turn ON the Oil Pump (this is
Output #103). Check the pressure gauge on the transfer
compartment wall. The normal operating pressure is
approximately
10-15
PSI
.
The pressure will affect the amount of pulse dampening
for the streams of oil. It primarily determines the
appearance of the oil stream, giving it a consistent flow on
the transfer roller. Having too little pressure (5 psi) is
not a fatal error, but excessive pressure (more than 20
pounds) may blow the pulse dampening tube.
Note: ALWAYS run a Calibration Check when adjusting the
pressure. This is the best way to insure the machine is
operating properly.
The conditioner pressure is primarily dependent on
viscosity
. The type of conditioner and the temperature are
what will affect the pressure the most. If an adjustment is
needed, remove the wing nut on the pressure regulator box
(on the bottom of the machine) and adjust the length of
tubing inside the box.
The factory supplied tubing is 3/16” OD at a length of
6”. This typically provides 12-15 pounds of pressure using
Defense-S at a temperature of 72
Fahrenheit.
Various lengths and sizes of tubing are available
depending on the type of conditioner being used. Sizes
range from 3/16” OD (light oil) to 1/4” OD. The length of
tubing may vary from a few inches to several feet. A chart
in the Appendix recommends the proper pressure regulator
tubing for each viscosity range, however adjustments may be
needed depending on the operating climate.
