2. Make certain that the retaining pins are in place and that they are secured with retaining rings.
CAUTION
Do not remove the retaining pins as permanent damage to the tool could result.
3. All pins, pivot points, and bearing surfaces should be protected with a THIN coat of any good SAE 20
motor oil. Do NOT oil excessively.
4. When the tool is not in use, keep levers closed to prevent objects from becoming lodged in the dies.
Store the tool in a clean, dry area.
5.2. Hydraulic Fluid Level Inspection (Figure 2)
1. Turn the tool upside down and clamp it in a vise so that the tool levers are in an upright position.
2. Release all pressure in the tool according to Step 6 of Section 4, CRIMPING PROCEDURE.
3. Turn the movable lever, and allow the lever to close until it stops. Be sure not to depress the plunger
when closing the lever.
NOTE
Keep lever in CLOSED position for remaining steps in this procedure.
4. Loosen the setscrew in cap of the stationary (reservoir) lever. See Figure 1.
5. With a view from the lever grip end, turn the lever COUNTERCLOCKWISE and remove the entire
reservoir lever to expose the bladder.
6. Remove the magnetic filler plug. If the bladder is full, no further check is necessary and the tool can
be re-assembled. If fluid level is low, proceed to the next step.
7. Fill the bladder with fluid. Recommended fluid is Dexron II, which is a transmission fluid available in
automotive parts and department stores. Use care to prevent air bubbles from forming while pouring
the fluid.
8. Refill the bladder to point of overflow, and replace the filler plug.
9. Re-assemble the stationary lever and tighten the cap setscrew. The tool is now ready for use.
