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.

4. Lock handle by releasing back pressure on lock·ring
until it clicks and handle doesn’t turn.
5. To torque fastener, keep hand centered on the grip
handle. Apply a slow steady force in the desired
direction until a click/impulse is heard or felt. Stop
pulling and allow the wrench to reset.

B. Set wrench to desired torque as follows:
EXAMPLE - 64ft. Ibs.
1. Keep slight rearward pull on lock-ring during all
adjustments.
2. Line up thimble edge with the “60” graduation
cross line and zero with vertical line. Wrench is
now set at 60 ft. Ibs. (See Figure I)
3. Turn handle and set thimble graduation to “4”
on vertical line. Wrench is now set at 64 ft. lbs.
(See Figure II)
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:
TW =
TA x L
L+A
TA = Torque exerted @ end of adapter
L = Distance between square drive and hand position
TW = Wrench scale reading
A = Length of adapter or extension
MAINTENANCE / SERVICE
TA
1. The torque wrench’s internal mechanism is
permanently lubricated during assembly. Do not
attempt to lubricate the internal mechanism.
TW
A
L
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.
Figure I
Figure II
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.
