6.Hold the Side Handle firmly and place other hand around Handle (28). Gen- tly squeeze the Trigger (49).

7.Place socket (not included) over desired nut, hold handle firmly and gently squeeze the Trigger.

8.If tool requires more force to accomplish task in Forward or Reverse setting, verify that the tool receives sufficient, unobstructed airflow (CFM) and increase the pressure (PSI) output of regulator up to maximum air pressure rating of the tool.

CAUTION! To prevent tool and accessory failure, resulting in injury:

Do not exceed tool’s maximum air pressure rating (90 PSI).

If tool still does not have sufficient force at maximum pressure and sufficient airflow, then a larger tool may be required.

9.When the nut is tightened or loos- ened, release the Trigger. Use a torque wrench to check the torque of the tightened nut.

10.To prevent accidents, turn off tool, detach air supply, safely discharge any residual air pressure in tool, and release Trigger after use. Clean ex- ternal surfaces of tool with clean, dry cloth, and apply a thin coat of tool oil to the anvil end. Store indoors out of children’s reach.
