beam alignment

6.Reach through the opening in the top of the reservoir left by the access plate and remove the outlet filter from the reservoir.

7.Thoroughly clean the filler cap, both filters, and the inside of the reservoir with solvent or mineral spirits. Make sure to wipe and dry all fluid residue from the parts, inside the reser- voir, and the surrounding area.

NOTICE

If fluid contamination is severe or there has been a component failure, have a qualified hydraulic technician thoroughly flush the system. Failure to follow this instruction could lead to premature wear of the hydrau- lic system and will void the warranty.

8.When all parts are clean and dry, re-assem- ble them and fill the reservoir with one of the recommended hydraulic fluids from Figure 54 or an equivalent.

9.With the front and rear access panels removed from the machine, re-connect the machine to power and turn it ON.

10.Carefully check all hoses and connections for leaks, then stand clear of the machine and move the beam back and forth to verify proper operation of the hydraulic system.

Note: Use a clean piece of cardboard to check for leaks—NOT your hands.

11.Turn the machine OFF, then re-install the front and rear access panels.

Beam Alignment

As the beam slides back and forth between the front and rear panels, four bronze pressure pads keep the beam and the attached tooling prop- erly aligned for safe and smooth operation. These pressure pads wear under normal conditions and require adjustment.

The tooling randomly being in and out of align- ment is a strong indicator that the beam may need alignment.

To align the beam:

 

1.DISCONNECT MACHINE FROM POWER!

2.Remove the shearing hold-down, shearing support frame, and shearing table from the machine.

3.Identify the four beam adjustment lock nuts and set screws on the front of the machine, as shown in Figure 58.

Lock Nuts & Set Screws

screws.

4.Back off the lock nut, then loosen the set screw (see the inset of Figure 58).

5.With very light pressure, re-tighten the set screw until you feel a slight drag.

6.While holding the set screw in place, re- tighten the lock nut.

7.Repeat Steps 5–6for the rest of the beam adjustment lock nuts and set screws.

8.Re-install the shearing table, shearing sup- port frame, and shearing hold-down.
