MAINTENANCE
1. The internal mechanism is permanently
lubricated at the factory during
assembly. Do not attempt to lubricate the
internal mechanism.
2. Clean torque wrench using dry materials
only. Do not immerse in any liquid.
3. Store torque wrench in its protective
case at the lowest setting to relieve
pressure on the compressive spring.
4. Accuracy should be checked twice
annually using suitable test equipment.
Reduce interval if wrench is in
continuous use.
5. Per ISO 6789-2:2017 for the first
recalibration, the period validity starts
with the user’s first operation of the
torque tool.

Dear Customer
You have purchased a Professional quality
JET JITW Series micrometer torque wrench.
It is a robust precision instrument with a
release accuracy of +/-3% of the torque
setting in the clockwise direction and +/-6%
in the counterclockwise direction. Properly
used and maintained, it will give you many
years of trouble-free service.
Please note: every instrument is only
as good as the user. Please read and
carefully observe the following operating
instructions.
SAFETY
Read operation manual completely
before using torque wrench. Keep
manual for future reference. Wear
safety goggles.
1. Periodic re-calibration is necessary to
maintain accuracy.
2. An out of calibration torque wrench can
cause part or tool breakage.
3. Do not exceed rated torque. Over-
torquing can cause wrench or part to fail.
4. Do not use torque wrench to break
fasteners loose.
5. Do not use cheater extension on handle.
6. Do not set the wrench above or below
the scale limit.
7. Return wrench to its lowest setting
after use.
8. Ratchet mechanism may slip or break
if dirty, mismatched, or worn parts are
used, or if direction lever is not fully
engaged.
ADJUSTMENT OF TORQUE
SETTING
To unlock handle hold tube and pull lock
ring back, allowing handle to turn CW or
CCW. Set wrench to desired torque as
follows: EXAMPLE – 64 FT/LBS.
1. Keep slight rearward pressure on the
lock ring during all adjustments.
2. Line up edge of lock ring scale with the
“60” mark on the tube and vertical line
on ring with vertical line on tube. Wrench
