If the shear fails to complete any of
these functions see the trouble

CAUTION: THE PRESSURE
TESTING PROCEDURE MUST BE
CONDUCTED BY A QUALIFIED
HYDRAULIC TECHNICIAN.
To test the pressure exerted at the
shear blades, disconnect the shear
from the power source. Remove the
shear blades from the frame.
Insert a pressure testing system
between the frame and the ram end
frame of the shear. PortaCo's Model
TS-00-X-O Tester Shear, is
recommended for this procedure.
(see figure 2.3B)
The model TS-00-X-O tester is
capable of testing most shears. It
features a pressure gauge with and
arrow indicating the optimum force
applied.
Position tester while closing the
shearing mechanism, aligning the
pins in the frames with the holes in
the tester. Hold the control lever
down till the needle, on the pressure
gauge, of the tester stops climbing.
The needle should be within 500 psi
of the red arrow. (figure 2.3C) When
testing follow the instructions
provided with the test equipment.
Testers other than PortaCo. Inc.'s
model TS-00-XX-O may instruct the
technician to perform the test in a
manor slightly different than the
procedure just described.
