USE OF ADAPTORS, EXTENSIONS AND UNIVERSALS
Anytime an adaptor, extension or universal is used with a torque wrench in such a way that fastener distance
is different than torque wrench square drive distance at calibration, an adjustment to head length is required
to get a proper fastener torque reading.
When using wobble extension or a universal, do not exceed more than 15 degrees of offset from
perpendicular drive.
CALIBRATION
Contact your Norbar sales representative for calibration services.
IMPORTANT:
CALIBRATION EVENTS ARE RECORDED IN WRENCH MEMORY WHICH PROVIDES
EVIDENCE TO VOID FACTORY CERTIFICATION
MAINTENANCE / SERVICE
Clean wrench by wiping with a damp cloth. DO NOT use solvents, thinners or carburettor cleaners.
DO NOT immerse in anything.
Service, repair and calibration are to be done by Norbar Service Cent
re’s only. Contact your Norbar
representative.
Ratchet head repair can be done by Norbar representative or user.
NOTE:
If display shows persistent "TORQUE ZERO ERROR" at power on, wrench is damaged and
must be returned for repair.
If display shows “ANGLE ERROR” in angle mode, fastener rotation speed has exceeded
capacity of wrench.
Wrench must be held still during angle zeroing. Motion is indicated by alternating dashes
“- -” on display.
Remove battery when stored for extended periods (Note: clock will revert to default
