Remove the old leveling band and cut the new band to the same length as the old one

Attach the new leveling band to the anchor point on the adjusting knob screw

Pass the leveling band over the sheaves and through the protective tube on the rear of the ram

Attach the left end of the leveling band to the servo valve anchor, pulling the band as tight as possible

Tighten the band by turning the tilt adjusting knob (clockwise) until .040\ clearance is provided between the servo valve anchor collar and the bottom of the servo valve mounting block. This is the zero point or neutral position for the servo valve"

The tilt adjusting knob screw should be recessed approximately 5/8\ (+1/8\") from the end of the knob when the servo valve is in the neutral position"

Check the level of the bed and ram per the previous instructions

Set tilt control adjusting knob and pointer to their 'zero' positions

Adjust the speed control cams so the ram approaches the bottom of the stroke in low speed

Mount a dial indicator on the extreme right end of the bed so it indicates the bottom reversal point of the ram

Verify that the ram is reversing consistently to the same indicator setting

Without changing the indicator or bottom stroke stop setting, reposition the dial indicator at the extreme left end of the bed

Run a number of strokes, adjusting the tilt control knob to raise or lower the left end of the ram, until the indicator reads the same as it had at the right end of the machine

Repeat Steps 4, 5 and 6 until both ends of machine have the same indicator reading at the ram reversal point

If necessary, replace the tilt adjusting knob graduated decal aligning its zero position. Also adjust the tilt pointer to its zero position
