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. Do not use a long extension with flex-drive at full flex.
CALIBRATION
Contact your Snap-on sales representative for calibration services.
CERTIFICATION
This TechAngle
®
wrench was calibrated at factory using angular displacement and torque
measurement instruments that are traceable to National Institute of Standards and Technology
(N.I.S.T.). Torque parameters comply with ISO 6789-2003 and ASME B107-28-2010. Note: no U.S. or
International Standards exist for angle wrenches.
MAINTENANCE / SERVICE
Clean wrench by wiping with a damp cloth. DO NOT use solvents, thinners or carburetor cleaners.
DO NOT immerse in anything.
Service, repair and calibration are to be done by Snap-on Service Centers only. Contact your
Snap-on Tools representative.
Ratchet head repair can be done by Snap-on Representative or user.
NOTES: - 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
settings).
IMPORTANT! Calibration events are recorded in wrench memory which
provides evidence to void factory certification.
