3. Be sure the reaction arm is positioned as shown in Figure 26. Then, fully depress the trigger, and keep it
depressed until the wrench stalls and the green LED pass light indicates that the fastening was properly
made. If the red (fail) LED is illuminated, the procedure was not completed properly, and the fastening
procedure must be repeated.

DANGER
!
Do not place any part of the body between the reaction arm and the reaction point. Failure
to comply could result in serious injury.
WARNING
!
Firmly support the tool during the entire fastening process to maintain control and to
prevent the tool from dropping. When the trigger is first depressed, the reaction arm of the tool may
“lock on” to the fastener, temporarily holding the tool in place. However, after the desired input torque
(or torque and angle) is applied, the reaction arm force will be released, and the weight of the tool may
shift toward the operator. Loss of control may occur and the tool could drop suddenly if it is not firmly
supported by the operator at this time. Failure to comply with these instructions and precautions could
result in death or serious personal injury.
If the trigger is released before the wrench stalls, the desired torque will not be applied to the
fastener. Do not repeatedly depress and release the trigger while tightening a fastener, as this will result in the
incorrect torque being applied.
4. After tightening is completed, release the trigger and remove the tool from the fastener.
