PREPARATION FOR USE

FITTING THE BATTERIES

1. Unscrew the battery cap.

2. Install batteries (2 x CR2032 as supplied) with their marked faces outwards,

and screw the cap back on.

operation and new ones should be fitted.

• Typical life of the batteries is 60 hours continuous use.

SWITCHING ON & OFF

1. Press the button to turn the wrench on.

• The LCD panel will display all characters and after 2 seconds the display

will show 0.00.

• The wrench will be in ‘TRACK’ mode, i.e., it will measure and display the

actual torque detected.

3. To manually turn the wrench off, press and release the button.

• If you do not use the wrench for 3-4 minutes it will turn off automatically.

4. Never turn the wrench off while force is applied.

DISPLAY LIGHTING

1. Press the button for the display lighting to come on.

2. Press again to turn the lighting off.

HOW TO SET ‘TRACK’ OR ‘PEAK’

• The display can alternate between peak and track (track is the default

mode and is not displayed.

HOW TO SELECT THE UNIT OF MEASUREMENT’

1. Press and hold the M/u button for 2 secs.

• The display will scroll quickly through the available units of measurement.

(N.m, lbs-in, lbf.ft and Kgf.m).

2. Release the M/u button when your required unit is shown.

Parts & Service: 020 8988 7400/E-mail:Part[email protected] or [email protected]

HOW TO SELECT PRE-SET TORQUE SETTING

measurement already chosen, press the + (SEt will flash briefly) the torque

value is displayed with the first digit flashing.

2. Press the + within 5 seconds to increase the number until the required

value is reached.

3. Press to move to the right and select the number using the +

button.

• The target torque will display for 3 seconds, then revert to 0.00.

4. Press M/u to set the value.

the nut/bolt to be tightened. Smoothly tighten your fastening, applying an

even pressure throughout the operation.

• As the target torque setting is approached, the LED will flash and the

alarm will bleep, before a continuous tone and light when the target

torque is reached or exceeded.

• If in PEAK mode, the red LED will light up and the alarm will bleep when

the target torque is reached and the highest measured reading will be

CARE OF THE WRENCH DURING USE

1. Take care not to drop the wrench on a hard surface and re-set the unit as

described under MAINTENANCE & CALIBRATION, should it be subjected to

sudden shock.

2. Take care not to damage the LCD display.

3. Never apply force with the torque wrench when the power is off. Always

turn the unit on before using it.

4. For assured accuracy of the wrench, periodic self re-setting is necessary as

described under MAINTENANCE & CALIBRATION.

5. Check that the wrench operating range is adequate for the anticipated

load before proceeding. Do not exceed the maximum rating of the

6. Re-set of the unit if you believe its capacity may have been exceeded.

7. Never use the wrench to undo bolts & nuts which may be excessively

tight. Very tight nuts and bolts should be loosened with a standard wrench

and the torque wrench used only for re-tightening.

8. Do not expose the wrench to extreme temperature, humidity or direct

sunlight for extended periods.

9. Avoid using knuckle or universal joints, as these could possibly result in

inaccurate torque settings.

STORAGE & CLEANING

1. Store in a clean, dry environment away from excess heat, humidity or dust.

2. If the wrench is not to be used for long periods of time it is advisable to

remove the batteries to avoid the risk of leaking.

3. Clean by wiping the tool and the display with a soft cloth. Never immerse

it in water or any type of solvent or cleaning fluid.

MAINTENANCE & CALIBRATION

The wrench has been calibrated at the factory order to ensure accurate

readings and should not require any re-calibration. The original calibration

certificate should be supplied.

If inaccuracy is suspected, contact your local Clarke dealer.

To maintain the accuracy of the wrench periodically reset by holding the

M/u and buttons together.

Do not attempt to dismantle the wrench.

BATTERY USE AND CARE

1. If when switching on, there is no reading on the display, or the ‘Battery

Condition Indicator’ on the panel is empty, the batteries must be

replaced.

2. Never combine used batteries with old ones or mix battery types.

3. Never use a battery if it is cracked or damaged.

4. Always dispose of old batteries appropriately. Never either dump or
