Laser information

Image alternative Laser class 1 based on standard IEC / EN 60825-1:2014 and corresponding to CFR 21 § 1040 (Laser Notice 56).

Indicator LEDs

The torque module can indicate various messages or states by means of the indicator LEDs.
Status
 Meaning
The LEDs show green.
  • When scanning: the barcode, QR code or data matrix code has been recognized.
  • When tightening, after the impact wrench has switched off automatically: the tightening operation was completed successfully.
The LEDs flash red.
  • When scanning: the barcode, QR code or data matrix code has not been recognized.
  • When tightening, after the impact wrench switches off: The threaded fastener could not be tightened in accordance with the selected settings. The reason for this could be, for example, that the impact wrench was switched off manually before the correct torque was achieved.
The LEDs flash yellow.
 Depending on the fastener, the module has detected the following:
  • A) The threaded fastener of the stud anchor or the threaded rod with chemical anchor had already been tightened and subsequently slackened. Consequently, the threaded fastener has been retightened in accordance with the defined parameters for retightening, and the tightening operation has been completed successfully.
  • B) The threaded fastener for installation systems and cast-in anchor channels had already been tightened, but the module is unable to tell whether the correct tightening torque was applied. If the threaded fastener was not tightened with a calibrated torque wrench or if the indicator LEDs of the module do not show green, the threaded fastener has to be checked with a calibrated torque wrench and - if necessary - tightened to the correct installation torque.

Buzzer

The torque module's buzzer can emit the following signal tones as audible feedback:

Hilti Li-ion batteries

Instructions for safety and useThis documentation uses the term battery to describe rechargeable Hilti Li-ion battery packs containing several Li-ion cells joined together. These batteries are to be used in Hilti power tools exclusively. Use only genuine Hilti batteries!
DescriptionHilti batteries have cell-management and cell-protection systems.
The batteries are composed of cells that contain lithium-ion storage materials capable of providing high specific energy density. Li-ion cells have a minimal memory effect, but they are very susceptible to external impact, deep discharge, and high temperatures.
The products approved for use with Hilti batteries can be found in your Hilti Store or at: www.hilti.group
Safety
  • Comply with the following safety instructions for the safe handling and use of Li-ion batteries. Failure to comply can lead to skin irritation, severe corrosive injury, chemical burns, fire and/or explosion.
  • Treat batteries with care in order to avoid damage and prevent leakage of fluids that are extremely harmful to health!
  • Do not under any circumstances modify or tamper with batteries!
  • Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C.
  • Never use or charge a battery that has suffered an impact or been damaged in any other way. Check your batteries regularly for signs of damage.
  • Never use recycled or repaired batteries.
  • Never use the battery or a battery-operated power tool as a striking tool.
  • Never expose batteries to the direct rays of the sun, elevated temperature, sparking, or open flame. This can lead to explosions.
  • Do not touch the battery poles with your fingers, tools, jewelry, or other electrically conductive objects. This can damage the battery and also cause material damage and personal injury.
  • Keep batteries away from rain, moisture and liquids. Penetrating moisture can cause short circuits, electric shock, burns, fire and explosions.
  • Use only chargers and power tools approved for the specific battery type. Read and follow the relevant operating instructions.
  • Do not use or store the battery in explosive environments.
  • If the battery is too hot to touch it may be defective. Put the battery in a place where it is clearly visible and where there is no risk of fire, at an adequate distance from flammable materials. Allow the battery to cool down. If it is still too hot to touch after an hour, the battery is faulty. Follow the instructions in the section headed What to do in case of a battery fire .
What to do in case of damaged batteries
  • Always contact Hilti when a battery is damaged.
  • Never use a battery that is leaking fluid.
  • Avoid direct eye and/or skin contact with fluid leaking from a battery. Always wear protective gloves and eye protection when undertaking tasks involving battery fluid.
  • Use a chemical spill cleanup kit to remove leaked battery fluid. Comply with the locally applicable cleanup regulations for battery fluid.
  • To store a damaged battery, place the battery in a non-flammable container and cover the battery with dry sand, chalk powder (CaCO3) or silicate (Vermiculite). Then seal the lid air-tight and store the container away from flammable gases, liquids or objects.
  • Dispose of the container at your Hilti Store , or consult your local governmental garbage disposal or public health and safety resources for disposal instructions. Comply with the locally applicable regulations for transporting damaged batteries!
What to do in case of dysfunctional batteries
  • Watch for abnormal battery behavior, such as faulty charging, unusually long charging times, noticeable power loss, unusual LED activity, or leaking fluids. These are signs of an internal problem.
  • If you suspect an internal battery problem, contact Hilti Service.
  • A battery that no longer works, cannot be recharged or leaks fluid has to be disposed of correctly. See the section headed Maintenance and disposal .
What to do in case of a battery fire
    WARNING
    Battery fire hazard! A burning battery releases hazardous and potentially explosive liquids and fumes that can lead to corrosion injuries, burns or explosions.
