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.

LOCK
LEVER
1. Pull back on the lock lever to unlock the set knob.
2. With the set knob turned to the lowest value, turn
the knob clockwise to the desired value indicated at
the set mark. If the value is exceeded, back off and
approach the proper seting from the low side.
3. Close the lock lever to lock the set knob at the
torque setting.
4. To torque fastener, keep hand centered on the
handle, apply a slow steady force in the clockwise
direction until a click/impulse is heard or felt. Stop
pulling and allow the wrench to reset.

UsE OF ExTENsIONs
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
TA
A
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.
