IMPORTANT SAFETY INSTRUCTIONS
WARNING
Do not apply torque above the rated capacity of the Digital Torque Checker
Over-torquing can cause breakage. Force against flex stops on flex head can cause head
breakage. An out of calibration checker can cause part or tool breakage. Broken hand tools,
sockets or accessories can cause injury. Excess force can cause crowfoot or flare nut
wrench slippage.
Read this manual completely before using the Digital Torque Checker
To ensure accuracy, checker must be securely mounted to a fixed bench.
For personal safety, and to avoid damage, follow good professional tool and fastener
installation practices.
Periodic recalibration is necessary to maintain accuracy.
Wear safety goggles; user and bystanders.
Be sure all components, including all adaptors, extensions, drivers and sockets are rated
to match or exceed torque being applied.
Observe all equipment, system and manufacturer's warnings, cautions and procedures
when using this tester.
Use correct size drive adapter for the wrench under test.
Do not use adapters showing wear or cracks.
Replace fasteners with rounded corners.
To avoid damaging checker: Never use with power off. Always turn ON checker so
applied torque is being measured.
Do not disconnect POWER while torque is applied or while wrench is in motion.
Do not use this checker to calibrate torque wrenches
Do not use extensions, such as a pipe, on handle of wrench.
Check that checker capacity matches or exceeds each application before
proceeding.
Verify calibration if dropped.
Never attempt to use an impact tool or pulse type tool on this checker.
Make sure ratchet direction lever on wrench is fully engaged in correct position.
Verify calibration of checker if you know or suspect its capacity has been exceeded.
Always adjust your stance to prevent a possible fall should something give while
checking torque wrench.
