TROUBLESHOOTING
The hydraulic system operates the Shear and Drive assemblies. They are interfaced
together and electronically activated. The hydraulic system pressure is factory set at 2000
psi and should not be changed. Some of the common problems that occur and their
solutions follow below.
1. Shear travels to the bottom of the stroke and does not return to the top of the
stroke. You can hear the hydraulic system laboring and pushing the Red
Shear Up Button does not return it to the top of stroke.
SOLUTION: Adjust the pressure switch (Figure 83) by turning the silver
knurled sleeve “A” counterclockwise until the shear goes up. Note: If you
turn the sleeve to far CCW, you will get problem #2 below on the next cut
made.
