FIGURE D
Handle in the Locked Position
IMPORTANT: The handle must be in the locked position before torque is applied. See Figure D.
5. Apply the wrench to the nut or bolt, and pull until you feel and/or hear the wrench click. Release. The wrench automatically
resets for the next operation.
IMPORTANT: To prevent equipment damage,
•
do not continue pulling on the wrench after the click.
•
use special care at low torque settings to stop pulling after the wrench clicks.
METRIC SETTINGS
1. The metric graduations are on the reverse side of the barrel and thimble, and the same steps are used to set a metric
torque.
NOTE: The metric scale is not in even graduations. Set the torque by aligning the thimble zero (0) with the cross line
on the tube that is nearest to the metric setting. See Figure E. Turn the handle to add metric graduations as needed to
bring the torque setting as close as possible to the required metric setting. See Figure F.
MAINTENANCE
1. If the torque wrench has not been used or has been in storage for some time, use it ten times at a low torque setting.
This releases an internal lubricant to coat the internal working parts again.
2. Keep the wrench set at a low torque when it's not being used.
3. Do not turn the handle below the lowest torque setting. If the handle is turned five or six turns below the minimum
setting, the handle will disengage.
The handle, when disengaged from the internal screw, turns free on the tube. The handle is held on the tube by an
internal spring-lock, and should never be pulled off the wrench. If the handle is accidentally removed, it should be
replaced immediately with enough force to overcome the resistance of the internal spring-lock. If the handle is replaced
without disturbing its internal parts, the wrench will remain in calibration. Use the following steps to engage the internal
screw again:
A. Gently push the handle toward the graduations scale while turning it to engage the internal screw again.
B. After the internal screw has been engaged, turn the handle while pulling backward lightly until the lowest torque
reading is set. The wrench can be used again, and the calibration has not been altered.
4. The tool is durable and designed for use in a shop, but the tool is also a precision measuring instrument and should be
treated as such.
5. Wipe the wrench clean. Do not immerse the wrench in any type of cleaner that may affect the high pressure lubricant
inside the tube.
