WARNING
Read operation manual completely
before using torque instrument and
store for future reference.
Wear safety goggles-both user and
bystanders
• An out of calibration torque wrench
can cause part or tool breakage
• Periodic re-calibration is necessary to
maintain accuracy
• Do not exceed rated torque as
overtorquing can cause wrench or part
failure
• Do not use torque instrument to break
fasteners loose
• Do not use cheater extension on the
handle to apply torque
• Broken or slipping tools can cause
injury.
CAUTION - RATCHET HEAD
Ratchet mechanism may slip or break
if dirty, mismatched or worn parts are
used, or direction lever is not fully
engaged. Ratchets that slip or break
can cause injury.
MAINTENANCE / sERvICE
1. The torque wrench’s internal mechanism is
permanently lubricated during assembly. Do not
attempt to lubricate the internal mechanism.
2. Clean torque wrench by wiping. Do not immerse.
3. Store torque wrench in protective tube at its lowest
torque setting. Do not force handle below lowest
setting.
ADJUsTMENTs OF
TORQUE sETTINgs
Before using all models of dial torque wrenches, it is
strongly suggested to cycle/operate them 3 times at
full scale in the torque direction in which they will be
used. Dial torque wrenches must always be
zeroed
before use.
Setting electric arm at zero with all torque readings
made from inner circle of numbers on the scale for
right-hand (CW) torquing, and the outer circle of
numbers on the scale for left-hand (CCW) torquing:
1. Turn bezel (CCW) until light and buzzer goes on.
2. Continue to turn bezel (CCW) until inner
zero of
desired scale (English or Metric) is lined up with
orange pusher needle.
3. Now turn bezel (CW) until light goes off and
orange pusher needle is aligned with desired torque
graduation in inner portion of scale orange pusher
needle is now preset to desired torque value.
UsE OF ExTENsIONs
AND ADAPTERs
When using an extension or adapter (increasing the
effective length of the torque wrench) the output
torque value will change. To calculate the new torque
output of the wrench use the following formula:
TA = Torque exerted @ end of adapter
L = Distance between square drive and hand position
TW = Wrench scale reading
A = Length of adapter or extension
A number of variables can affect torque accuracy.
These include the length of an adapter or extension,
length of the wrench and variations in hand position
on the wrench will affect the accuracy of the above
calculation.
TW =
TA x L
L + A
4. Apply force to handle in the (CW) direction. When
the preset torque value is reached the light and
buzzer will go on. When force on the handle is
released orange pusher needle will return to the
preset torque value.
5. To change the preset torque value to another,
turn the bezel as required to the new torque value
within the same dial graduation and proceed as in
step 4 above.
7. IMPORTANT - Always make sure that the electric
contact arm is zeroed.
