Troubleshooting WSHR-3017
Table 4
Problem
Possible cause
Remedy
Irregular cut.
Stock rest not adjusted properly.
Adjust stock rest so that strut is
perpendicular to cutting die
surface. Ensure that knobs are
tightened down on guide bars.
Locking knobs which hold die in
frame of main unit have loosened
(possibly from vibration over long-
term use).
Check tightness of locking knobs
after about every 100 cuts.
Hydraulic ram won’t
move, or produces
insufficient pressure.
Error with hydraulic source.
Consult hydraulic pump
manufacturer’s documentation to
troubleshoot.
Shear blade won’t
return to rest
position.
Hydraulic dump valve not
functioning.
Inspect and correct dump valve
function on hydraulic system.
Blade movement blocked by
obstruction.
Clean debris from blade area.
Strut will insert
through fixed die,
but won’t go through
cutting die.
Cutting die is too far forward.
Turn adjustment screw on
cylinder to move the start
position of cutting die, until strut
can enter. (5mm hex wrench
required.)
Strut is slightly curved or deformed.
(Back-to-back strut is sometimes
more susceptible to this.)
