SAFETY
ALERT
SYMBOL
Read and understand all of the
instructions and safety information
in this manual before operating or
servicing this tool.
Failure to observe this warning
could result in severe injury or death.
Electric shock hazard:
This tool is not insulated. When
using this unit on or near energized
electrical lines, use proper personal
protective equipment.
Failure to observe this warning could
result in severe injury or death.
Wear eye protection when operating
or servicing this tool.
Failure to wear eye protection could
result in serious eye injury from
ying debris or hydraulic oil.
Do not use solvents or ammable
liquids to clean the pressing tool.
Solvents or ammable liquids could
ignite and cause serious injury or
property damage.
Keep hands away from the pressing
tool head when pressing.
Failure to observe this warning could
result in severe injury or death.
An incomplete press can cause a leak.
• Use proper tting and tubing combinations.
Improper combinations can result in an incom-
plete press.
• The relief valve will sound and the pressing tool
automatically retracts when a complete press
has been achieved. If you do not hear a “pop”
and the pressing tool does not automatically
retract, the press is not complete.
Failure to observe these warnings could result in
severe injury or property damage.
Skin injection hazard:
Oil under pressure easily punctures
skin causing serious injury,
gangrene, or death. If you are injured
by escaping oil, seek medical atten-
tion immediately.
• Do not use hands to check for
leaks.
• Depressurize the hydraulic system
before servicing.

injury from harmful fumes or burns from ying d ebris.
• Do not operate the tool without a tting in place.
Damage to the pressing head can result.
• Do not use this tool for continuous use. After
50 cycles, allow the tool to cool for 15 minutes.
• Do not secure this tool in a vise. This tool is
designed for hand-held operation.
• This tool may be used in damp or wet environ-
ments; however, air-drying is recommended
before use if the tool becomes soaked. Damage
may result when the tool is operated prior to

soaked.
• Use this tool for the manufacturer’s intended
purpose only.
Failure to observe these precautions may result in
injury or property damage.
Do not allow anything to contact the battery
terminals.
• Do not immerse the batteries in liquid. Liquid
may create a short circuit and damage the
battery. If batteries are immersed, contact your
service center for proper handling.
• Do not place the battery into a pocket, tool
pouch, or tool box with conductive objects.
Conductive objects may create a short circuit
and damage the battery.
• Do not place a battery on moist ground or
grass. Moisture may create a short circuit and
damage the battery.
Failure to observe these precautions may result in
injury or property damage.
• Do not store the battery at more than 60 °C
(140 °F). Damage to the battery can result.
• Do not use another manufacturer’s charger.
Other manufacturers’ chargers may overcharge
and damage the battery.

PC-2, PC-3, PC-4 Pressing Chains
1. Select the proper size pressing chain for the
intended application. Examine the chain for wear,
damage, dirt or copper buildup. Replace if worn or
damaged and remove any dirt or copper buildup
with a brush or soft cloth with light lubricating oil.
2. Disengage the release pin on the pressing chain
(see gures below) and open the chain. Install the
pressing chain around the tting to be pressed and
re-engage the pin on the pressing chain.
3. Check that the red protective sleeve is in the rear
position and the chains 2-1/2" to 4" marking is
visible on the PC-100 tool. If not, depress the button
on the protective sleeve and move the sleeve to the
rear position (see gures below). Release the button
to secure the protective sleeve.
4. Push the retract button on the PC-100 tool to
completely retract the drive rollers (see gure
below).
Before installing the pressing jaws,
remove battery to avoid unintentional
operation.
Failure to observe this warning could
result in severe injury or property
damage.

below) and rotate counterclockwise to disengage
the pin on the pressing tool.
Operation (cont’d)
6. Install the adapter jaw into the pressing tool and
align mounting hole in jaw with pin. Depress the pin
to secure the adapter jaw (see gures below).
7. Compress the ends of the adapter jaw together to
open the jaws and install the adapter jaw into the
pressing chain (see gures below).
8. Reinstall the battery and depress the tool trigger
to press the tting. Continue to depress the trigger
until the relief valve actuates and the drive rollers
automatically retract.

Notes:
If the drive rollers do not automatically retract, the
press is incomplete.
The pressing cycle can be interrupted at any
moment by releasing the trigger.
It is normal for the battery load display to light at both
the beginning and near the end of the pressing cycle.
9. Release the trigger until the drive rollers retract
completely.
10. Compress the adapter jaw ends together to open
the jaws and remove the adapter jaw from the
pressing chain (see below).

11. Disengage the release pin on the pressing chain and
remove the pressing chain from the pressed tting.
Notes:
The pressing chain must close completely to ensure
a leak-free connection. Always check that the
chain closes completely during a pressing cycle and
no foreign objects are between the pressing chain and
the mechanism.
The pressing cycle can be interrupted at any
moment by releasing the trigger.
If it is necessary to remove the chain before a
pressing cycle is complete, push the retract button
on the PC-100. Pushing the retract button will cause
the drive rollers to retract completely so that the
adapter jaw and chain can be removed.
If the pressing cycle must be stopped before
the crimp is complete, and the chain has to be
removed from the fitting, or the adapter jaw has to
be removed from the chain, the fitting should be
replaced or pressed a second time.
The PC-100 and pressing chains are intended to
press NIBCO press fittings onto type K, L, and M
hard-drawn copper tubing.

Maintenance
Each Operating Day
Before use:
1. Wipe all surfaces clean on the pressing chain with a
cloth. Remove any dirt with a brush.
2. Inspect pressing chain for wear or damage such as
cracks, gouges, or chips.
3. Inspect the PC-100 Pressing Tool for damage or
leaks. If damage is detected, return the tool to an
authorized NIBCO service center for inspection.
Skin injection hazard:
Do not use hands to check for
oil leaks. High pressure oil easily
punctures skin causing serious
injury, gangrene, or death. If injured,
seek medical help immediately to
remove oil.
After use:
1. Wipe all surfaces clean on the pressing chain with a
cloth. Remove any dirt with a brush.
2. Place the pressing chain in the carrying case. Store
in a cool, dry place.
Monthly
1. Thoroughly clean all surfaces.
2. Oil the pin and bolt joints.
Annually or After 10,000 Presses
Return the chain to an authorized NIBCO service center
for inspection.
