IMPORTANT SAFETY INSTRUCTIONS

WARNING Risk of flying particles.

Over-torquing can cause breakage. Force against flex stops on flex head can cause head
breakage. An out of calibration angle wrench 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 ELECTRONIC WRENCH.
To insure accuracy, work must not move in angle mode.
For personal safety and to avoid wrench 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 the torque being applied.
Observe all equipment, system and manufacturer's warnings, cautions and procedures
when using this wrench.
Use the correct size socket for the fastener.
Do not use sockets showing wear or cracks.
Replace fasteners with rounded corners.
To avoid damaging the wrench: Never use the wrench with the power off. Always turn ON
the wrench so the applied torque is being measured.

Do not press ON/RESET while torque is applied or while the wrench is in motion.
Never use this wrench to break fasteners loose.
Do not use extensions, such as a pipe, on the handle of the wrench.
Check that the wrench capacity matches or exceeds each application before proceeding.
Verify calibration if dropped.
Make sure the ratchet direction lever is fully engaged in the correct position.
Verify the calibration of the wrench if you know or suspect its capacity has been exceeded.
Do not force the head of flex head drives against stops.
Always pull - do not push - on the wrench handle and adjust your stance to prevent a
possible fall should something give.

WARNING Electrical Shock Hazard.

Electrical shock can cause injury. Metal handle is not isolated.
Do not use on live electrical circuits.

Use of Negative Offsets
Note: Enter a negative value for the offset when used in the reverse direction with the flex head and when calculating the sum of

the interchangeable head and offset lengths.

ℎ



When the length of an offset (sum of head minus offset for interchangeable head) is negative, the maximum fastener target is
limited by the following formulas:
100 ft-lb wrench:

Maximum Target Torque = offset * 7 + 100

Offset Max Target

-1" 93 ft-lb

-2" 86 ft-lb

-3" 79 ft-lb

-4" 72 ft-lb

250 ft-lb wrench:
Maximum Target Torque = offset * 11 + 250

Offset Max Target
-1" 239 ft-lb
-2" 228 ft-lb
-3" 217 ft-lb
-4" 206 ft-lb

Note: When using a negative offset, entering a target torque greater than the maximum values above may cause an overtorque
error before reaching the fastener target torque and possibly damage the wrench.

date, plus the Cal Interval, the "CAL NEEDED" message will be displayed on power up and after a re-zero. Pressing the
ENTER button will continue to the target menu. Applying torque while the "CAL NEEDED" message is displayed will
immediately display the torque or angle measurement and return to the target menu when released.

Note: As an alternative to calibration interval, a Calibration Cycle Counter is provided in the Calibration menu (Contact your
local Snap-on Repair Center regarding the Calibration menu) Each time a measurement cycle reaches target torque,
the calibration cycle counter is incremented. When torque is recalibrated, the calibration counter is automatically reset
to zero. The user can disable the calibration interval check and use the number of cycles since last calibration to decide
when to recalibrate.

Angle uncalibrated Calibrate angle

34

• USE OF ADAPTORS, EXTENSIONS AND UNIVERSALS

Anytime an adaptor, extension or universal is used with a torque wrench in such a way that the fastener distance is different
than the torque wrench square drive distance at calibration, an adjustment to the 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 the flex-drive at full flex.

• CALIBRATION

Contact your Snap-on sales representative for calibration services or refer to the C-TECHTM Calibration Manual.

• CERTIFICATION

This torque-angle wrench was calibrated at the factory using angular displacement
and torque measurement instruments that are traceable to the 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.

IMPORTANT! Calibration events are recorded in the wrench memory
which provides evidence to void factory certification.

• MAINTENANCE / SERVICE

Clean the wrench by wiping with a damp cloth. DO NOT use solvents, thinners
or carburetor cleaners. DO NOT immerse in anything. Service and repairs are to
be done by Snap-on Service Centers only. Contact your Snap-on Tools representative.
Ratchet head repair kits can be ordered from a Snap-on Representative.
NOTES: - If the display shows persistent "TORQUE ZERO ERROR" at power on, the wrench is damaged and

must be returned for repair
- If the display shows “ANGLE ERROR” in the angle mode, fastener rotation
speed has exceeded the capacity of the wrench.
- The wrench must be held still during angle zeroing. Motion is

indicated by alternating dashes “- -” on the display
- Remove battery when stored for extended periods (Note: clock will revert to default settings).

35

• Battery Replacement

Replace with three Lithium "AA" cells only.
Note: When replacing the batteries, the real-time-clock will maintain the date and time for 20 minutes.
