Maintenance
• Keep the tool clean. Use the tool with care to keep dirt
and grit out of the hydraulic system. Contamination is
the most common cause of failure for hydraulic tools.
• Store the tool in its original case with the ram fully
retracted.
• Occasionally lubricate the die release button
assemblies. A molybdenum disulfide grease is
recommended.
• Inspect the hydraulic hoses periodically.
• Periodically verify that the power source reaches
700 bar (10,000 psi). Refer to the “Periodic Relief
Valve Check” in this manual.
Periodic Relief Valve Check
Skin injection hazard:
• Do not use fingers or hands to
check for leaks.
• Depressurize hydraulic system
before servicing.
High pressure oil easily punctures
skin causing serious injury, gangrene
or death. If injured seek medical help
immediately to remove oil.
Wear eye protection when using this
tool.
Failure to wear eye protection could
result in serious eye injury from flying
debris or hydraulic oil.
Pinch points:
Keep hands away from closing dies.
Failure to observe this warning could
result in severe injury or death.
Inspect tool and dies before use. Replace any worn or
damaged parts. A damaged or improperly assembled
tool could break and strike nearby personnel with suf-
ficient force to cause severe injury or death.
• Do not operate crimping tool without dies in place.
Damage to the ram or crimping tool head may
result.
• Do not perform any service or maintenance other
than as described in this manual. Injury or damage
to the tool may result.
Periodically verify that your hydraulic power source
is supplying between 9600 and 10,400 psi (662 and
717 bar).
Use a test-quality pressure gauge on the supply line
from the hydraulic power source.
1. Refer to the instructions supplied with the pressure
gauge.
2. Stop the flow of hydraulic oil from the power source.
3. Connect the pressure gauge to the supply line of the
power source.
4. Install the set of test dies into the crimping tool.
5. Activate the power source until the ram has
advanced and the power source reaches relief
pressure. The pressure gauge should read between
9600 psi and 10,400 psi (662 bar and 717 bar) .
6. Release the pressure by stopping flow from your
power source. The ram will retract.
If crimp pressures are low, the hydraulic power source
relief valve may need adjustment.
Relief valve adjustments must be performed accord-
ing to the instructions provided with the hydraulic
power source.
