Each crimping head is assembled and inspected

before shipment. It is recommended that the crimping

head be inspected immediately upon its arrival at your

facility, and at regularly scheduled intervals, to ensure

that the crimping head has not been damaged during

handling. Frequency of inspection depends upon the

following: care, amount of use, and handling of the

head; type and size of products crimped; degree of

operator skill; and environmental conditions.

6.1. Cleaning

Remove accumulations of dirt and grease on the

crimping head, especially in areas where dies are

installed and terminals are crimped. Clean the entire

head frequently with a clean, lint--free cloth.

6.2. Visual Inspection

Refer to Figure 3 and proceed as follows:

1. With hydraulic pressure released, inspect the

assembled head for nicks, scratches, and cracks.

Inspect for cracks especially at the corners of the

yoke and around the top of the cylinder.

Check Die Areas

for Damage

Check for Excessive Wear

at Pivot Pin and Latch Pin

2. Inspect pivot pin holes and latch pin holes for

wear. Replace parts, as needed.

3. Activate power unit. Raise ram to UP position.

Inspect flat and round surfaces of ram for galling

(fretting or wear by friction), cracks, or oil leakage.

Release pressure and make sure that ram retracts

smoothly.

4. If head shows evidence of galling, cracks, oil

leakage, or rough cycling, return the crimping head

for repair (refer to Section 7, REPLACEMENT

AND REPAIR).

Once a year, or every 7,500 cycles (whichever

comes first), the hydraulic head should be

returned to Tyco Electronics for magnetic particle

inspection. Additionally, inspect and service the

head (as described in Figure 3) every month or

1,000 cycles. Refer to Instruction Sheet

408--8909.

6.3. Crimping Head Check--Out Procedure

If the ram fails to return to the DOWN position after

completion of a crimping cycle, the cause may be in

the crimping head. To determine whether or not the

trouble is in the crimping head, proceed as follows:

A. Electric Hydraulic Pumps 1583660--[ ]

Press the retract/release button on the hand remote

pendant or foot remote, and hold for several seconds.

This will release any pressure in the hydraulic system.

If the ram returns to DOWN position, the trouble is

NOT in the crimping head. If ram does not return,

ensure that the coupler is fully engaged. If coupler is

engaged and ran still does not go DOWN, return the

crimping head to Tyco Electronics for repairs.

B. Foot Hydraulic Pump 1583659--1

Depress the pressure release pedal.

C. Hand Hydraulic Pump 1583661--1

Activate the pressure release knob.

7. REPLACEMENT AND REPAIR

Customer--replaceable parts are listed in Figure 4.

A complete inventory can be stocked and controlled

to prevent lost time when replacement of parts is

necessary. Order replacement parts through your
