2. Release all pressure in tool according to instructions in step 6 of Section 4, CRIMPING PROCEDURE.
3. Release striker and allow moveable lever to close until it stops.
NOTE
Keep handle in CLOSED position for remaining steps in this inspection.
4. Loosen setscrew in cap of stationary (reservoir) lever. See Figure 1.
5. With view from handle grip end, turn handle COUNTERCLOCKWISE and remove entire reservoir
lever to expose bladder.
6. Remove magnetic filler plug and wipe clean. If bladder is full, no further check is necessary and tool
can be re-assembled. If fluid level is low, proceed to Step 7.
7. Fill bladder with fluid. Use care to prevent air bubbles from forming while pouring the fluid.
8. Refill bladder to point of overflow, and replace filler plug.
9. Re-assemble reservoir handle and tighten cap setscrew. Tool is now ready for use.
5.3. Periodic Inspection
It is recommended at least one inspection a month. The inspection frequency should be based on the amount
of use, ambient working conditions, operator training and skill, and your company's established standards.
Lubrication
Keep all pins, pivot points, and bearing surfaces lubricated with SAE 20 motor oil as follows:
Tool used in daily production - lubricate daily
Tool used daily (occasionally) - lubricate weekly
Tool used weekly - lubricate monthly
Wipe excess oil from tool, particularly from crimping area. Oil transferred from the crimping area onto
certain terminations may affect the electrical characteristics of an application.
Visual Inspection
1. Make certain all retaining pins are in place and secured with retaining rings. If replacements are
necessary, refer to parts listed in Figure 3.
2. Inspect head assembly for worn, cracked, or broken areas. If damage is evident, return the tool for
evaluation and repair. See Section 6, REPLACEMENT AND REPAIR.
Crimping Pressure Inspection
Check the crimping pressure to ensure that dies are fully bottomed before pressure is reduced by the
internal bypass valve. The inspection should be performed using each set of dies that will be used in the
head.
Recommended fluid is Dexron† II, a transmission fluid available in automotive parts and department stores. Dexron is a trademark.
