NOTE:
For counterclockwise rotation, the adjustment
lever is set to the “R” position.

the reaction point.
Fig. 9
11. To tighten a fastener (or to apply torque in the
clockwise direction): Be sure the adjustment lever
is set to the “F” position, and that the reaction
arm is positioned as shown in Fig. 8. Then, fully
depress the trigger, and keep it depressed until
the wrench stalls.
NOTICE:
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 could result in the incorrect torque being
applied.
12. To loosen a fastener (or to apply torque in the
counterclockwise direction): Be sure that the
adjustment lever is set to the “R” position and
that the reaction arm is positioned as shown in
Fig. 9. Then, fully depress the trigger and keep it
depressed until the fastener loosens.
13. After tightening or loosening is completed,
release the trigger and remove the tool from the
fastener. In some cases, it may be necessary to
briefly operate the tool in the opposite direction
to release the counter torque load from the
reaction arm.
14. When finished using the tool, turn off the air
supply, disconnect the hoses, remove the
reaction arm and store the tool in the case.
