NOTE
To adjust the Spinner move forward, close and open sequence:
1. Use a 5/32" allen wrench to rotate the Push cylinder pressure reducing valve at Port V1
counter-clockwise until refusal.
2. Use a 5/32" allen wrench to rotate the Spinner Door sequence valve at Port V2 clockwise until
refusal.
3. Use a 1/4" allen wrench to rotate the Spinner retract needle valve at Port V9 clockwise
until refusal.
4. Use a 5/32" allen wrench to rotate the Spinner motor sequence valve at Port VG/S on the main
hydraulic block clockwise until refusal. See Maintenance & Repair, p. 67.
5. Set the Selector switch to Break. See Operate, p. 28. Adjust the spinner to the drill pipe tube
OD. See Operate, p. 25. Place the HawkJaw on the drill pipe connection. See Operate, p. 26-
27.
6. Press the Spin button. Rotate the Push cylinder pressure reducing valve at Port V1 clock-
wise until the spinner moves forward and the chain touches the pipe. If the chain forces the
HawkJaw away from the pipe, back off on the adjustment until the spinner chain touches the
pipe without forcing the Hawkjaw back. The spinner will close if you hold the spin button too long.
7. Rotate the Spinner Door sequence valve at Port V2 counter-clockwise until the spinner
doors begin to close as the spinner chain touches the pipe. For each adjustment, press and
hold the Spin button to test the adjustment. Continue to rotate the adjustment counter-
clockwise until the spinner begins to close before the chain touches the pipe. Rotate the
adjustment clockwise until the spinner begins to close as the spinner chain touches the
pipe. Lock in the adjustment.
8. Adjust the needle valve V9 clockwise until the spinner opens smoothly while pulling back.
For each adjustment, press and hold the Spin button until the spinner doors close. Release the
Spin button to test the adjustment. If the rollers grab the pipe while retracting, adjust the
needle valve clockwise. If the chain forces the HawkJaw backwards while retracting,
adjust the needle valve counter-clockwise.
9. Adjust the spinner motor sequence valve at Port VG/S. Use a 3/16" allen wrench to rotate the
sequence valve counter-clockwise until the chain moves before the doors close. Next, rotate the
adjustment clockwise until the spinner doors close before the chain moves. Rotate one half-
turn clockwise. Lock in the adjustment. See Maintenance & Repair, p. 67, Drawings, p. 114.
