2. Insert the terminal or splice in stationary die 

according to instruction sheet packaged with 

dies.

To avoid personal injury, be sure to exercise 

caution while holding terminals, splices, or wire in 

the crimping area.

3. Pump movable lever until moving die grips 

terminal or splice.

Do not deform wire barrel of terminal or splice.

4. Insert stripped wire into wire barrel of terminal 

or splice.

5. Continue pumping movable lever. A slight click 

may be heard, indicating the pump has shifted 

into the high-pressure stage. Continue pumping 

movable lever and completely crimp the 

connector. This tool has a built-in by-pass 

cartridge that will automatically activate when full 

pressure is reached. There will be a noticeable 

decrease in handle pressure when the by-pass is 

reached.

A high pitched squeaking sound is normal when the 

tool is operating in the high pressure stage,

6. Turn movable lever (to actuate striker), and 

compress levers to depress plunger. Movable die 

will now retract. See Figure 1.

7. Remove the crimped terminal or splice.

If terminal or splice sticks in die after crimping, 

apply a rocking action to remove it from die.

8. Inspect the crimped terminal or splice 

according to inspection procedure on instruction 

sheet packaged with the dies.

5. MAINTENANCE AND INSPECTION

It is recommended that a maintenance and inspection 

program be performed periodically to ensure 

dependable and uniform terminations.

The hand tool is inspected before being shipped; 

however, It is recommended that the tool be inspected 

immediately upon arrival at your facility to ensure that 

the tool has not been damaged during shipment.

5.1. Daily Maintenance

1. Immerse the hand tool (levers partially closed) 

in a reliable commercial degreasing compound to 

remove accumulated dirt, grease, and foreign 

matter. When degreasing compound is not 

available, wipe the tool clean with a soft, lint-free 

cloth. Do NOT use hard or abrasive objects that 

could damage the tool.

2. Protect all pins, pivot points, and bearing 

surfaces with a THIN coat of any good grade  

SAE‡ 20 motor oil. Do NOT oil excessively.

3. When the tool is not in use, keep the levers 

closed to prevent objects from becoming lodged 

in the dies. Store the tool in a clean dry area.

5.2. Periodic Inspection

Though recommendations call for at least one 

inspection a month, actual frequency depends on:

The care, amount of use, and handling of the hand 

tool.

The presence of abnormal amounts of dust and 

dirt.

The degree of operator skill, and 

Your own established standards.

A. 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.

A slight weeping of oil from the ram and pump 

seals is normal and required to keep the moving 

parts lubricated. Excessive leakage indicates a 

need for seal replacement. Refer to Section 6, 

RETURN/REPLACEMENT.

B. Visual Inspection

1. Make certain all retaining pins are in place and 

secured with retaining rings. If replacements are 

necessary, return the tool for repair. See Section 

6, RETURN/REPLACEMENT.

2. Inspect for worn, cracked, or broken areas. If 

damage is evident, return the tool for evaluation 

and repair as described in Section 6, RETURN/

REPLACEMENT.
