MAINTENANCE.

ALL WIRING MUST BE DONE IN ACCORDANCE WITH NA-

TIONAL, STATE AND LOCAL ELECTRICAL CODES.

1 Install the electrical control box in a convenient

location.

2 Wire the electrical control box. Note: Electrical

control boxes are different for different power sup­plies. You must have the proper control box for your
power supply. Refer to Tables 1 and 2 for applicable
control box numbers.

2.1 Attach terminals L1, L2, and L3, and earth
ground to the applicable power supply. See wir-

ing diagram inside control box cover.

2.2 The connection between the SEC 400 and the
electrical control box is pre--wired and is
approximately 20 feet long. Tighten the com­pression nut on the female connector to ensure
proper sealing. Refer to Figure 1.

3 Install a balancer above the work station on a trolley.

3 Making the cut:

3.1 Start the saw by depressing both triggers simul­taneously.

3.2 Saw through the tail bone. The saw should be
pointing upward when making this cut. Do not

exert pressure on the SEC 400; guide the saw to
insure a straight cut.

3.3 After the tail and aitch bones have been split,
saw through the loin area. The SEC 400 should

be in a horizontal position during this cut.

3.4 Saw through the shoulder and neck.

3.5 When the desired cut is achieved, release the
triggers. Continue to hold the tool with both

hands until the saw blade comes to a complete
stop.
