FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.

USING THE TOOL (Continued)

Do not remove the Inlet Plug without first discon-
necting the live air supply.

Whenever the Angle Head is installed or reposi-
tioned, the Throttle Lever  must be positioned so
that reaction torque will not tend to retain the
throttle in the “ON” position.

When installing or removing the output device on
any tool, ALWAYS grasp a metal component of
the tool while tightening or loosening the Coupling
Nut or Spindle Cap.  Acceptable clamping 
locations include, but are not limited to, the hex on
the Gear Case, the Tool Hanger, the Torque Reac-
tion Arm or any metal Mounting Plate.  NEVER
grasp the composite tool body or handle in vise
jaws to restrain the torque of the Coupling Nut or
Spindle Cap.  Such practice will result in damage
to the tool.

Do not use power units and gear trains that exceed
the capability of the output device.

The Tube Nut Attachment has an opening on 
the front side for construction and application
purposes.  DO NOT, under any circumstance
place your fingers in this opening.

The Torque Reaction Bar must be positioned
against a positive stop.  Do not use the Bar as a
dead handle and take all precautions to make 
certain the operator’s hand cannot be pinched
between the Bar and a solid object.

When operated continuously for long periods of
time, Series D Nutrunners may become hot at the
spindle end of the tool.  Take all precautions 
necessary to avoid skin contact with the hot 
surfaces.  Prolonged contact may result in burns.

All Series D Torque Control Wrenches and 
Nutrunners with reverse capability have rotation-
al arrows molded into the housing in the area of
the reversing mechanism.  When the direction
switching device is positioned nearest the molded
circular arrow with an “F” in the center, spindle
rotation will be forward or clockwise direction.
When the direction switching device is positioned
nearest the molded circular arrow with an “R” in
the center, spindle rotation will be reverse or 
counterclockwise direction.
