2. Shear travels to the bottom of the stroke and returns to the top of the stroke
without cutting the panel completely through.
SOLUTION: Press and hold the Green Shear Down Button until the panel is cut
off. Remove the cut panel and jog material out 2 or 3 inches past the shear.
Adjust the pressure switch (Figure 83) by turning the silver knurled sleeve
“A” clockwise 1/8 of a turn. Press the Shear Down Button again. Check to
see if the panel is cut off completely. If not, repeat this procedure until the
cut is made with one stroke of the shear. Note: If you turn the knurled
sleeve too far CW you will experience problem #1 above.
3. Shear is at the top of the stroke, you can hear the hydraulic system laboring
and you cannot run the next panel.
SOLUTION: Remove the Shear Cover. Note the 2 Limit Switch Arms “A”
(Figure 84). Lift the arms one at a time. If one of them stops the hydraulic
system laboring then that Limit Switch arm needs to be adjusted. If neither
of them stops it, lift both arms at the same time to see if it stops. If it does
then both arms need adjusting. ADJUSTMENT: Tape one or both Limit
Switch Arms “A” to the Top Shear Bar “B”. Loosen Hex Nut “C” until
spring tension is released. Using a small flat tipped screwdriver, turn
Slotted Stud “D” toward the entry end of the machine until you hear a
click and stop. Repeat this a few times until you can stop right when the
click occurs. While holding this position, tighten Hex Nut “C” to lock in
adjustment. Adjust one or both sides as required from test above. Start the
engine. If the adjustment/adjustments were done correctly, the hydraulic
system should no longer be laboring and you should be able to run the
next panel.
