SAFETY MESSAGES

SAFETY MESSAGES

WARNING - Risk of ying 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 crow
foot or flare nut wrench slippage.

READ THIS MANUAL COMPLETELY BEFORE
USING THE CDI COMPUTORQ II 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 tool accuracy.

USERS AND BYSTANDERS SHOULD ALWAYS
WEAR EYE PROTECTION

• Be sure all components, including

adapters, extensions, drivers and sockets
are rated to match or exceed the torque
being applied with tool.

• Observe all equipment, system and

manufacturer’s warnings, cautions and
procedures when using this wrench.

• Always use the correct size socket for the

fastener being torqued.

• Do not use damaged sockets, showing

signs of wear or cracks.

• Always replace damaged fasteners before

applying torque.

• Never use extensions, such as a pipe, on

the handle of the wrench.

• Always make sure the ratchet Forward/

Reverse Switch is fully engaged in the
correct position.

• Always verify that the wrench capacity

matches or exceeds each application before
proceeding.

• Always verify the calibration of the wrench

if you know or suspect its capacity has been
exceeded.

• Never force the head of ex head drives

against stops.

• Always pull - do not push - on the wrench

handle and adjust your stance to prevent a
possible fall while applying torque.

WARNING - Electrical Shock Hazard

• Electrical shock can cause injury.

• Plastic handle is not insulated.

• Do not use on live electrical circuits.

MAINTENANcE / SERVIcE

1. IMPORTANT - Service, repair and calibration are

to be performed by CDI Torque Products only.

Calibration by the user is recorded in the wrench
and voids factory certification.

2. The torque wrench’s internal mechanism is

permanently lubricated during assembly. Do not

attempt to lubricate the internal mechanism.

WARNING - To avoid damaging Computor II

Wrench

• Never operate wrench when powered OFF.
Always power wrench ON prior to applying

torque.

• Do not press ON key while torque is being

applied.

• Never use this wrench to loosen fasteners.

3. To safely clean the torque wrench, wipe with a damp

cloth. NEVER use solvents, thinners, or engine

cleaners of any kind. NEVER immerse the torque
wrench in liquids of any kind.

4. Store torque wrench in protective tube at its lowest

torque setting. Do not force handle below lowest

setting.

OPERATING INSTRUcTIONS

Please Note: There is an “off-on” slide switch located on

the right side of the wrench The wrench is shipped from

the factoiy with the switch in the “off” position. Before
use, slide the switch up or “on” Place the switch in the
“off” position only if the wrench is to be stored or not

used for a period of time. Otherwise, leave the switch in

the “on” position.

ELECTRONIC WRENCH SETUP

• TO TURN WRENCH “ON”

Press Button #1 (on/off).
Slide battery selector switch “Up” (on) or press Button
#1 (on/off) if slide switch is already in
the “Up” position.

The red and green lights will flash.
Zeros will flash and then be displayed on
the LCD along with the unit of torque measure.
The wrench is ready to use.

NOTE: If button #1 is pressed and held when first
turning the wrench “on”, the torque range capacity

and current software version of program will be
displayed. When first turning the wrench

on (sliding the switch “up”), the LCD will
ash “data good” then ash all zeros.

• TO CHANGE MODE OF OPERATION: “TRACK” OR

“PEAK”

1. Press Button #4 (set-up) one time.

• TO SET A TARGET TORQUE VALUE:

1. Press Button #4 (set-up) three times.
The rst zero (0) on the digital display will blink.

2. To set a nominal target value into wrench memory,

press Button #2 (store/send). As this button is
repeatedly pressed, numbers zero through nine (0-9)

will be displayed.

3. When the correct number is displayed on the first

digit, press Button #4 (setup). This will “hold” that

number and cause the second digit to blink.

4. Again, press button #2 (store/send) until the value
desired is displayed (0-9).

5. Press Button #4 (set-up) to “hold” this value and

cause the third digit to blink.

6. Continue the same steps above to set the values for
the third and fourth digits.

7. After pressing Button #4 (set-up) on the last digit, the
decimal point will be blinking. This “point” can be

placed in three different locations by pressing Button

#2 (store/send). Press Button #4 (set-up) when the

decimal point is in the desired location.

• TO SET PERCENTAGES OF TOLERANCES:

1. Press Button #4 (set up), until the rst

digit of two in the upper right corner is
blinking.

2. This will be the rst of two digits in the (+) maximum

tolerance percentage. Again, as before, press Button

#2 (store/send) until the rst digit is set at the
FlASHING desired value. Press Button #4 (set-up)

to accept this value and move to the next blinking
number.

3. Repeat the above procedure for the
second digit. When the desired digit is

displayed, press Button #4 (set-up). The

maximum tolerance is now entered.

4. The rst digit of the (-) minimum tolerance should
be ashing. Press Button #2 (store/send) to scroll
through numbers (0-9). Press Button #4 (set-up) to

accept this value and move to the second flashing

digit. Press Button #2 (store/send) to scroll through
numbers (0-9) until the second desired number is

displayed.

NOTE: Review the entire LCD at this time.
If everything is as desired, press Button #3

OPERATING INSTRUcTIONS

(recall) to accept all parameters into wrench memory.
These parameters will remain in memory until they are
changed.

EXAMPLE SET-UP

the following steps would be necessary:

1. Press Button #1 to turn the wrench “on”
( check to see if “peak” is active

2. Press Button #4 twice and verify if the active torque

units are in in. lbs.

3. Press Button #4 one more time to activate the rst
blinking “0”.

4. Press Button #2 until the number “1” is displayed.

5. Press Button #4 ve times to scroll through the three

(100 in.lbs. - 2%). The green light and

audible tone will continue until the torque
value reaches the maximum preset limit of 102 in.lbs.

(100 in.lbs. RED LIGHT + 2%). The red & green lights
will ash and intermittent tones will sound if the &
TONE torque value exceeds the maximum

percentage allowed. Loud audible tones
and flashing lights will continue even

when an over torque (of the range of the
wrench) condition occurs. The display
will then show “OVER” in small letters in the extreme
