Replacing the batteries
1. Unscrew the battery compartment located at the handles end
2. Remove old batteries
3. Insert new batteries, ‘+’ terminal facing towards the LCD
4. Screw the battery compartment shut
Initialize the torqe wrench

Initialization of the torque wrench starts
Service and inspection
- Clean with dry cloth only, do not immerse into benzine or solvents
- Advise: Return the torque wrench once a year to the manufacturer for inspection
The TorcoTronic was tested and found to comply with the CE standard.

Note: Should the ‘LbAt’ display appear during
measuring with rated value (higher power
consumption) it is possible to continue measuring
with display only (measuring with rated value
disabled) for a brief period. In case ‘LbAt’ is
displayed immediately after waking up the torque
wrench from sleep mode, the batteries are
exhausted and have to be replaced.
