IMPORTANT SAFETY INFORMATION
SAFETY
ALERT
SYMBOL
This symbol is used to call your attention to hazards
or unsafe practices which could result in an injury or
property damage. The signal word, dened below,
indicates the severity of the hazard. The message
after the signal word provides information for pre-
venting or avoiding the hazard.
Immediate hazards which, if not avoided, WILL result
in severe injury or death.
Hazards which, if not avoided, COULD result in
severe injury or death.
Hazards or unsafe practices which, if not avoided,
MAY result in injury or property damage.
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.
Skin injection hazard:
Do not use hands to check for oil
leaks. Oil under pressure easily
punctures skin. If injured, seek
medical attention immediately to
remove oil.
Failure to observe this warning
could result in serious injury, gan-
grene, or death.
Do not use solvents or ammable
liquids to clean the tool body.
Solvents or ammable liquids could
ignite and cause serious injury or
property damage.
An incomplete crimp can cause a re.
• Use proper die, connector, and cable combina-
tions. Improper combinations can result in an
incomplete crimp.
• The relief valve sounds and the ram automatically
retracts to indicate a completed crimp. If you do
not hear the sound of the relieve valve or the ram
does not automatically retract, the crimp is not
complete.
Failure to observe these warnings could result in
severe injury or death.

injury from harmful fumes or burns from ying
debris.
Inspect tool and dies before use. Replace any
worn or damaged parts. A damaged or improp-
erly assembled tool can break and strike nearby
personnel.
Failure to observe this warning could result in severe
injury or death.
• Do not use this tool for continuous use. After 30 to
40 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

drying when electrical components are 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 122 °F
(50°C) or less than –4 °F (–20 °C). Damage to the
battery can result.
• Do not use another manufacturer’s charger. Other
manufacturers’ chargers may overcharge and
damage the battery.
• Do not attempt to open the battery. It contains no
user-serviceable parts.
Failure to observe these precautions may result in
injury or property damage.
Do not perform any service or maintenance other
than as described in this manual. Injury or damage
to the tool may result.
Failure to observe this precaution may result in injury
and property damage.

Crimping Procedure
1. Insert conductor into the connector and align the
tool and die on the connector. Start in the center
for splices; start on the end, nearest the pad, for
terminals.
2. Activate the tool by pulling the trigger. Continue to
hold the trigger until the ram retracts. This is the
signal that the crimp is complete.
3. Continue crimping the connector until the correct
number of crimps has been completed. Work from
the center to the outer edges for splices, alternat-
ing sides, if possible, for the best compression
connections.
An incomplete crimp can cause a re.
• Use proper die, connector, and cable combina-
tions. Improper combinations can result in an
incomplete crimp.
• The relief valve sounds and the ram automatically
retracts to indicate a completed crimp. If you do
not hear the sound of the relieve valve or the ram
does not automatically retract, the crimp is not
complete.
Failure to observe these warnings could result in
severe injury or death.
