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
indicated torque setting or up to 20% of full scale.
Do not force handle below lowest setting.

1.
To set the torque values, loosen locking set screw
(A) with a 3/32” hex wrench.
2.
Insert interchangeable plain drive head (D)
(consult factory for model number) into receptacle
(F) until the locking pin (E) is fully engaged with
the corresponding receptacle hole. (See Figure I).
3.
Place a T- handle hex wrench through adjusting
hex opening (C) at rear of handle grip until
engaging the adjusting screw (B).
4.
Place the wrench on a torque tester. Turn
adjusting screw (B) with the T- handle hex wrench
clockwise to increase torque and counter-
clockwise to decrease torque.
5.
To set torque, apply a slow steady force on the
pre-set wrench. Turn adjusting screw (B) until the
desired torque setting is displayed on the torque
tester.
6.
Tighten the locking set screw to 10 in, lbs. (A). To
ensure that wrench setting is repeatable, cycle
three more times. If the readings are not as
desired, repeat steps 1-5.
RELEASE
FORCE TO RESET
APPLY FORCE
To verify calibration or to torque a fastener,
keep hand centered on the handle grip. Apply
a slow force until a click/impulse is heard or
felt. Stop and allow the wrench to reset.

NOTE:
Some interchangeable heads used in pre-
set torque wrenches have lengths that
vary.
It is recommended that the pre-set torque
wrenches are to be calibrated with the
interchangeable head that is to be used to
assure the greatest accuracy in calibration.
Hex wrenches used to adjust torque
settings will vary in length.
