Disassembly and Reassembly of the Pulse Unit (cont.)

4. The Pulse Unit is now set for maximum fill. Any measurable change in fluid level will affect the torque

output and the consistency of the tool.

5. Put the Pulse Unit in Vacuum Tank to purge all air out of the Pulse Unit, proceed to step 13. If you do

not have a vacuum tank, proceed to step 6.

6. Fill the 3cc Syringe with fluid. Turn Syringe upside-down and push plunger to purge all air from the

Syringe.

7. Insert the Needle on the Syringe and insert it into the Oil fill hole. Fill the Pulse Unit completely with

fluid from the bottom up, slowly.

8. Fill 3cc Syringe with fluid and again purge all air bubbles.

9. Turn the Anvil clockwise only to purge the air from Pulse Unit. As air bubbles appear, over-fill unit with

3cc Syringe and continue to turn the Anvil clockwise. Go slowly by seal point to prevent air from

sucking back into the Pulse Unit.

10. When no bubbles are present, Pulse Unit is air free.

11. Install Oil Fill Plug and cycle Pulse Unit two to three times. This will push fluid down under the Relief

Valve. Remove Oil Filler Plug and purge for air.

12. Rotate Anvil until Driving Blade is again visible in Oil Filler Opening and turn Blade 1/8 of a turn from

opening.

13. Fill 3cc Syringe with 1cc of fluid for accurate drawing of fluid.

14. Wipe off excess fluid from top of the unit. Oil level should be at the top of the Oil Filler Plug Threads

before drawing.

15. Using the 3cc Syringe, draw out the specified amount of fluid per specifications for each model (see chart).

16. Thread Oil Filler Plug into hole and tighten.

17. You are now ready to test the Pulse Unit.

F. Torque Adjustment

1. To properly adjust the torque, turn the Adjuster with proper size Allen wrench clockwise until the

Adjuster Valve bottoms-out. Then back off counter-clockwise for maximum torque as follows: UX-T,

UXR-T and Alpha-T series; back off one half turn.

2. Reverse procedure for minimum torque.
