IMPORTANT SAFETY INSTRUCTIONS
WARNING Risk of flying particles.
Do not apply torque above rated capacity of DTC.
Over-torquing can cause breakage. Force against flex stops on flex head can cause
head breakage. An out of calibration DTC 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 DTC.
For personal safety and to avoid DTC 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 checker.
Use correct size adapter for torque wrench.
Do not use sockets showing wear or cracks.
Replace fasteners with rounded corners.
To avoid damaging DTC: Never use checker with power off. Always turn ON
DTC so applied torque is being measured.
Do not press POWER while torque is applied.
Never use this checker to calibrate torque wrenches.
Do not use extensions, such as a pipe, on handle of wrench.
Check that DTC capacity matches or exceeds each application before
proceeding.
Verify calibration if dropped.
Never attempt to test an impact tool or pulse type tool on this checker.
Make sure ratchet direction lever is fully engaged in correct position.
Verify calibration of DTC 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.
Do not attempt to recharge Alkaline cells.
Store DTC in dry place.
Remove batteries when storing checker unused for periods longer than 3
months.
WARNING Electrical Shock Hazard.
Electrical shock can cause injury. Do not use on live electrical circuits.

CERTIFICATION
This DTC was calibrated at factory using torque calibration system that is traceable to National
Institute of Standards and Technology (N.I.S.T.). Testing parameters comply with ISO 6789:2003
and ASME B107:300-2010 (B107.29).
MAINTENANCE / SERVICE
Clean DTC 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 CDI Service Center only. Contact your
CDI Torque Products representative.
CALIBRATION
Contact your CDI sales representative for calibration services.
IMPORTANT! Calibration events are recorded in wrench memory which
provides evidence to void factory certification of compliance.
