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.
NOTE
i
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.
NOTE
i
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:
S The care, amount of use, and handling of the
hand tool.
S The presence of abnormal amounts of dust and
dirt.
S The degree of operator skill.
S 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.
NOTE
i
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.
C. 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 tool.
1. Install dies according to Section 3, DIE
INSERTION AND REMOVAL, and the instruction
sheet packaged with the dies.
2. Select wire and terminal or splice for dies being
used.
3. Place terminal or splice in dies according to
instruction sheet packaged with dies.
4. Perform crimping procedure as described in
Section 4, CRIMPING PROCEDURE, Steps 3
through 5. Do not release hydraulic pressure at this
time.
