408-6757
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.
1. Install the dies according to Section 3, DIE INSERTION AND REMOVAL, and the instruction sheet
packaged with the dies.
2. Select the wire and terminal or splice for the dies being used.
3. Place the terminal or splice in the dies according to the instruction sheet packaged with the dies.
4. Perform the crimping procedure as described in Section 4, CRIMPING PROCEDURE, Steps 3
through 5. Do not release the hydraulic pressure at this time.
5. Check the clearance between bottoming surfaces of the crimping dies. If clearance is 0.025 mm
[.001 in.] or less, crimp pressure is satisfactory. If clearance exceeds 0.025 mm [.001 in.], crimp
pressure is considered not satisfactory. See Section 6, REPLACEMENT AND REPAIR.
If the tool conforms to these inspection procedures, lubricate it with a THIN coat of any good SAE 20
motor oil and return it to service.
6. REPLACEMENT AND REPAIR
Customer-replaceable parts are listed in Figure 3. A complete inventory should be stocked and controlled to
prevent lost time when replacement of parts is necessary. Parts other than those listed should be replaced by
TE Connectivity to ensure quality and reliability. Order replacement parts through your TE Representative, or
