Wera Safe-Torque Torque Wrenches
INTRODUCTION
Congratulations on your purchase of a quality torque wrench with slip-over mechanism from the Wera Safe-Torque series. The maximum measurement deviation of the device is ±10% of the set value. Each torque wrench comes with a Factory Calibration Certificate, with which you can check the accuracy of your wrench. To ensure a long service life for the tool, please read the following instructions carefully.
Safe-Torque A 1/Safe-Torque A 2
Setting the desired torque
Hold the torque wrench by the handle and unlock the wrench. To do this, pull
out the lock button located at the end of the handle to the end stop Now you
can set the torque wrench to the value you require. To do this, hold the
wrench at the main pipe and turn the handle
until the desired torque value is shown at the corresponding scales below the green line in the fine-scale window and you hear and feel it click into place. The Nm interim values can be read off of the fine adjustment scale
The fine adjustment scale refers exclusively to the Nm interim values. The lb/ft interim values can not be read in this way. Once the desired value has been set, lock the wrench by fully depressing the lock button again. This prevents unintentional adjustment of the value. Please note that locking is only possible in the setting position where the displayed value on the fine scale is directly behind the read mark.
Handling the torque wrench
For placing or removing a socket (A 1 model only) on the ¼” square drive, press the button on the ratchet head
Switch the ratchet between clockwise and anti-clockwise torque-control via the rotary switch control on the ratchet head (pic. 4 k). Place the tool on the coupling and apply force in the desired direction until you feel the wrench slip over. This triggers the torque (clearly noticeable both audibly and haptically). The slide-over mechanism works for both clockwise and anti- clockwise torque-control. The torque function of the tool can be deactivated via the green sliding element (pic. 4 l). Pushing the switch up so that the red ring (pic. 4 z) marked “Torque OFF” becomes visible will switch off the slip-over mechanism. The tool can now be used like a conventional ratchet. Always pay attention to the position of the sliding switch to make sure the tool is in the desired mode.
Important instructions for care and maintenance
Please never extend the torque wrench with a pipe or similar, as this may
alter the set value and cause damage to the wrench. Treat your torque wrench
like a measuring instrument (Vernier caliper, micrometer, etc.). Never immerse
the device in petrol or solvents; otherwise the lubrication of the mechanics
will be compromised.
Checking the calibration
Since mechanical equipment is subject to wear, it is necessary to control the
calibration of the torque wrench after 5,000 load cycles, or about 1 year
following initial use, and annually thereafter. For very intensive use, this
should happen more often.
