PREPARATION FOR USE

FITTING THE BATTERIES

1. Remove the screw securing the battery cover to the back of the unit and lift off the cover.
2. Install batteries (2 x CR2032 as supplied) with their marked faces to the right and refit the cover.
   • If the batteries are in poor condition the icon will flash during operation and new ones should be fitted.
   • The typical life of the batteries is 60 hours continuous use.

SWITCHING ON & OFF

1. Press the button to turn the device on.
   • The LCD panel will display all characters and after 2 seconds the display will show 0.0.
   • The adaptor will be in ‘track’ mode, i.e., it will measure and display the actual torque detected.

2. To manually turn the adaptor off, press and release the button.
   • If you do not use the adaptor for 3-4 minutes it will turn off automatically.

3. Never turn the adaptor off while force is applied.

DISPLAY LIGHTING

1. Press the button to illuminate the back light.
2. Press again to turn the back light off.

HOW TO SET ‘TRACK’ OR ‘PEAK’

1. Press the button to select the current torque value or Peak (the max torque value), if preferred.
   • The display can alternate between Peak and Track (Track is the default mode but only Peak will be displayed when selected).

HOW TO SELECT THE UNIT OF MEASUREMENT

1. Press and hold the button for 3 secs.
   • The display will scroll quickly through the available units of measurement.
   (N.m, lbs-in, lbf.ft and Kgf.m).

2. Release the button when your required unit is shown.

HOW TO SELECT TORQUE SETTING

1. With the unit of measurement already chosen, press the (SEt will flash briefly) and the torque value will be displayed with the first digit flashing.
   • The value will display for 3 seconds then revert to 0.0, i.e., step 2 must be commenced within 3 seconds.
   • The value chosen must always be at least 10% of the maximum capability of the wrench.

2. Press and hold the to zero the display and set another value.

3. Press the to increase the number until the required value is reached.

4. Press to move to the r ight and select the next number using the button.
   • The target torque will display for 3 seconds, then revert to 0.0.

5. Press to set the value.

OPERATION

1. Connect the bottom (male) square drive of the adaptor, to the socket or extension bar, perpendicular to the nut/bolt to be tightened.
2. Connect any 1/2” square drive wrench to the top (female) socket of the adaptor.
3. Smoothly tighten your fastening, applying an even pressure.
   • If in TRACK mode, the actual torque applied at any moment will be displayed. 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 audible warning sound will be heard when the target torque is reached and the highest measured reading will be displayed. Press the button to clear this reading before taking another measurement.

CARE OF THE WRENCH DURING USE

1. Take care not to drop the adaptor 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 adaptor when the power is off. Always turn the unit on before using it.
4. For assured accuracy of the adaptor, periodic self re-setting is necessary as described under MAINTENANCE & CALIBRATION.
5. Re-set the adaptor if you believe its capacity may have been exceeded.
6. Check that the adaptor operating range is adequate for the anticipated load before proceeding. Do not exceed the maximum rating of the adaptor (360Nm or equivalent units).
7. Never use the adaptor to undo bolts & nuts which may be excessively tight. Very tight nuts and bolts should be loosened with a standard wrench and the torque adaptor used only for re-tightening.
8. Do not expose the adaptor 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 adaptor 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 adaptor and the display with a soft cloth. Never immerse it in water or any type of solvent or cleaning fluid.
