OPERATOR INSTRUcTION

1. Turn the wrench

ON by momentarily pushing the

ON/OFF key. The display will return to the mode of
operation and preset values previously set up.

2. To change the mode of operation,

TORQUE or

ANGLE, scroll the selections by momentarily
pushing the

UNITS key. The preset values for each

mode will be displayed.

3. Use the

UP and DOWN keys to change the preset

values.
(Note:

TORQUE is also measured in ANGLE mode).

4. Grasp the center of the handle and slowly apply

torque to the fastener until the

Green LED or audible

buzzer alerts you to stop.

5. Release torque. Note the

PEAK reading flashing on

the display for 10 seconds, unless torque is re-
applied or the

ON/OFF key is pushed to clear the

display.

6. In

ANGLE mode, place the wrench on a flat surface

during

ZEROTARE.

7. The

BAR GRAPH shows measured TORQUE or ANGLE

as a percentage (10-100%) of Preset.

USE OF ADAPTERS,

ExTENSIONS AND UNIVERSALS

Anytime an adapter, extension or universal is used
with a torque wrench in such a way that the fastener
distance is different that the torque wrench square
drive distance, an adjustment to the set torque is
required to get proper fastener torque.

Fastener torque equals torque wrench square drive
torque. Wrench setting is equal to desired fastener
torque.

Fastener torque equals torque wrench square drive
torque. Wrench setting is equal to desired fastener
torque.

Fastener torque is greater than torque wrench square
drive torque. Calculated setting will be lower than
desired fastener torque.

Fastener torque is less than torque wrench square drive
torque. Calculated setting will be higher than desired
fastener torque.

When using a universal or wobble extension, do
not exceed more than 15 degrees of offset from
perpendicular drive.
