sAFETY MEssAGEs
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.
To set orange pusher & blue follower needle for right-
hand (CW) torquing:
1. Turn bezel in left-hand (CCW) direction until, blue
memory follower needle contacts orange pusher
needle.
2. Continue to turn bezel left-hand (CCW) until blue
memory follower needle is lined up with
zero (0) of
outer graduation on portion of dial for IN.LB., FT.LB.,
METRIC readings.
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
3. Apply force on the wrench handle until blue follower
needle reaches desired torque. When force is released
orange pusher needle will return to
zero and blue
memory follower needle will remain at torque applied.
4. For repetitive torque operations (once the zero
has been set as instructed above), the blue memory
follower needle can be returned to
zero by use of the
follower needle knob. It is ready for the next operation.
5. IMPORTANT - When using the memory feature
always make sure that the blue follower memory
needle is on
zero before torquing.
