Important safety notice
Digital tool
system security
WREN battery torque wrench is safe and reliable. Failure to follow the precautionary
measures and instructions outlined below may result in injury to tools, operators, and
personnel present.
WREN is not responsible for any such injury.
The intended use of battery torque wrenches is for commercial and industrial bolt
tightening.
Please do not operate the battery torque wrench until you have read and understood
this manual and noticed the safety tips displayed in the battery torque wrench system
and the entire manual.
Only qualified personnel trained in the safe operation of battery torque wrenches can
attempt to install and operate battery torque wrenches.
Improper operation and use can cause serious or fatal injuries.
Do not try to disassemble or repair the battery torque wrench, this will invalidate the
warranty. If there is a malfunction, damage or the tool does not operate normally,
please contact our company.
Technical support (see section 6.0-contact us)
Only store and use battery torque wrenches in a compliant environment. Please refer
to Section 1.2.3-Environmental Specifications.
Do not operate an battery torque wrench in a flammable and explosive environment,
including but not limited to: flammable liquid, gas or dust. Battery torque wrenches
produce sparks that can ignite these substances.
Do not expose the battery torque wrench to a humid environment. Water will damage
the battery torque wrench and increase the risk of electric shock.
After a long period of use, the battery torque wrench will heat up. It is recommended
to use short and medium time intervals to cool down to prevent operator injury or
damage to the battery torque wrench.
During the operation of the battery torque wrench, wear goggles to ensure that the
human body is kept away from the contact point between the moving parts of the
wrench and the reaction arm.
Do not exceed the maximum torque of the battery torque wrench, which will damage
the tool, and no warranty service is provided.

The battery torque wrench has been calibrated. The calibration must be carried out
under the guidance of our staff. Improper calibration will reduce the torque accuracy
and damage the tools and bolts.
Safety matters of lithium battery pack
This battery torque wrench can only use the supporting lithium battery pack. Using
other batteries will damage the tool.
Lithium battery packs can only be charged on the matching battery charger. If you
use an incompatible charger, it will cause damage to the lithium battery.
Keep the lithium battery pack away from any metal objects. If metal objects come
into contact with the battery, it will short-circuit the battery and cause injury to the
operator and the battery.
Do not expose the lithium battery pack to a humid environment, as this will cause
damage to the lithium battery and increase the risk of electric shock.
Do not use defective or deformed lithium batteries. Do not try to open the battery,
do not short-circuit the battery, otherwise it will damage the battery and the
operator.
If liquid comes out of the battery, avoid contact. Once in contact, rinse immediately
with water. If it gets into eyes accidentally, rinse immediately with water and seek
medical attention. Liquid from the battery may cause irritation or burns.
The battery pack cannot be disposed of with conventional waste products. Please
contact us or your dealer to return the battery.

2.3 Lithium Battery Pack
Notice! Battery torque wrenches can only use the matching lithium battery pack. Using other
batteries will damage them and cause personal injury.
Keep the lithium battery pack away from any metal objects. If a metal object is used to
connect the battery, it will short-circuit the battery and cause injury to the operator and the
battery.
The lithium battery powers the battery torque wrench motor and the liquid crystal display. In
order for the battery torque wrench to be in the best working condition, confirm that the
battery is fully charged and in good condition before use. Under optimal conditions, the
battery can cycle approximately 100 feet of torque at 50% of the maximum torque.
Note: Operating torque, battery condition, aging degree and operating temperature will affect
the actual torque cycle times.
2.3.1 Insert and remove the lithium battery
Insert lithium battery：
1. Confirm that the trigger is in the off position.
2. Align the battery with the slot at the bottom of the handle.
3. Slide the battery into place.
4. Test whether the battery is in place and try to slide its position.
Remove the lithium battery:
1. Press the battery release button.
2. Slide the battery out from under the handle.
2.3.2 Check Charging
Check Battery Charging
1. Press the red "charge" button of the battery
The four green indicator lights will light up. If all the indicators are on, the battery is fully charged. If no
indicator light is on, the battery is exhausted and needs to be charged. (Refer to 2.1.1-Battery charging)
2.4 Battery Charger
Notice! Lithium battery packs can only be charged on the matching battery charger. If you
use an incompatible charger, it will cause damage to the lithium battery.
The charging status of the battery charger is used to remind the operator that it is
charging, charging is complete or there is a fault.
