1. The internal mechanism of the torque wrench has been
calibrated and lubricated before final assembly. DO
NOT attempt to open the wrench's internal mechanism
for any reason. Doing so will void the warranty.
2. Do not submerge the torque wrench in water or any
other liquids.
3. When not in use always store the torque wrench in its
protective case. Be sure before storage that you have
reset the torque setting back to zero.
4. Re-calibration is necessary to maintain accuracy once a
year or every 5000 cycles. Using a torque wrench that
is not regularly calibrated may cause damage to the
tool and personal property
MAINTANENCE
1. To unlock the handle, hold the body firmly and pull the
rear cap downward. This will allow you to rotate the
handle clockwise or counter clockwise to your desired
torque measurement.
2. Set the desired torque by rotating the handle clockwise
or counter clockwise. For example 75 ft. lbs:
a. Rotate the handle until the vertical red line on the
major scale is lined up with 70 ft. lbs.
b. Then slowly rotate the handle clockwise and set the
minor scale to five (5).
3. Push the rear cap back to its locked position.
4. Install the proper socket or attachment to the square
drive end and apply to the object receiving torque.
Rotate the wrench in a clockwise steady motion until
you feel/hear a "CLICK" sound.
5.
IMPORTANT: ALWAYS
reset the major scale torque
measurement back to "ZERO" when you are finished
using the wrench. This will ensure the internal body
spring maintains accurate tension which prolongs the
life and accuracy of the product.
