PLACING TOOL IN SERVICE
•Always operate, inspect and maintain this tool in
accordance with all regulations (local, state, feder-
al and country), that may apply to hand held/hand
operated pneumatic tools.
•For safety, top performance, and maximum
durability of parts, operate this tool at 90 psig
(6.2 bar/620 kPa) maximum air pressure at the
inlet with 3/8” (10 mm) inside diameter air supply
hose.
•Always turn off the air supply and disconnect the
air supply hose before installing, removing or
adjusting any accessory on this tool, or before
performing any maintenance on this tool.
•Do not use damaged, frayed or deteriorated air
hoses and fittings.
•Be sure all hoses and fittings are the correct size
and are tightly secured. See Dwg. TPD905–1 for a
typical piping arrangement.
•Always use clean, dry air at 90 psig maximum air
pressure. Dust, corrosive fumes and/or excessive
moisture can ruin the motor of an air tool.

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.

LUBRICATION
Adequate lubrication is imperative for maximum performance and durability of the gearing in these Tools.
Ingersoll–Rand No. 10 Oil
The use of an air line lubricator is recommended. For permanent installations, we recommend using an Ingersoll–Rand
No. C18–03–FKG0–28 Filter–Lubricator–Regulator Unit.
If an air line lubricator is not used, inject 2 cc of the recommended oil into the air inlet before attaching the air hose and after
each eight hours of operation.
ADJUSTMENTS
Before placing your Ingersoll–Rand Torque Control Wrench Hand–Held Power Module in service, several optional adjust-
ments can be made to the unit which will enhance the performance of the tool or improve operator comfort. Selection and
adjustments should be made prior to placing the tool in service.
TOP/REAR AIR INLET
The air supply hose can be connected conventionally to the rear of the unit or connected to the side of the Handle if an over-
head air supply is available. To change the inlet connection, proceed as follows:
Do not remove the Inlet Plug (24) without first disconnecting the live air supply.
Do not thread pipe thread fittings directly into the Inlet Bushing or Inlet Plug locations in the Handle.
1. Disconnect the air supply hose if it is attached to the tool.
2. Using an adjustable wrench, unscrew and remove the Inlet Bushing (3) and Inlet Bushing Seal (5).
3. Using a 1/4”hex wrench, unscrew and remove the Inlet Plug (24) and Inlet Plug Seal (25).
4. Install the Inlet Plug and Seal in the desired location and tighten the Plug between 30 and 40 in–lb (3.4 and 4.5 Nm)
torque. (Refer to TPD1844).

CLUTCH ADJUSTMENT
To adjust the clutch on these Angle Wrenches, proceed as follows:
1. Rotate the Clutch Adjusting Hole Cover (52) until the slot in the Cover aligns with a corresponding slot in the Motor
Housing Assembly (34).
2. Using a wrench on the square drive spindle or hex bit insert, rotate the output spindle until the half circle notch on the
motor end of the Clutch Adjusting Nut Lock (69) is visible in the slot.
3. Insert a #1 Phillips head screwdriver into the notch of the Nut Lock and one of the notches in the Clutch Adjusting Nut
(68). Insert the screwdriver far enough to create a gap between the Nut Lock and Adjusting Nut.
4. Turn the screwdriver clockwise (as you would to tighten a screw) to increase the the clutch torque or counterclockwise to
decrease the clutch torque.
5. Final clutch adjustment should be set on the job.
GRIP ADJUSTMENT
The Handle (1) of the Angle Wrench has an Adjustable Grip (9) which permits individual operators to select one of three
handle thickness positions. Operators with large hands can select the bulkiest position and operators with small hands can
select the smallest size. To adjust the Grip, proceed as follows:
1. Grasp the grooved ends of the Adjustable Grip Latch (10), and spreading the ends slightly, raise the Latch to its upper-
most position. (Refer to TPD1255).
(Dwg. TPD1255)

MAINTENANCE SECTION
Always turn off the air supply and disconnect the air
supply hose before installing, removing or adjusting
any accessory on this tool, or before performing any
maintenance on this tool. Failure to do so could result
in injury.
Always use protective eyewear when performing main-
tenance on a tool or operating a tool.
DISASSEMBLY
Disassembly of the DAA and DAAT Clutch
1. Carefully grasp the Housing Sleeve Assembly (50)
with the clutch end upward, and using a wrench on
the flats of the Clutch Housing (84), unscrew and
remove the Clutch Housing.
2. Grasp the Clutch Spindle (80) and pull the assembled
clutch off the Rotor (41).
3. Remove the Shutoff Spool (73) and Valve Return
Spring (74) from either the shaft of the Rotor or the
inside of the Clutch Shaft (66).
4. Insert the jaws of snap ring pliers into the holes of the
Clutch Adjusting Nut Stop (67) and expand the Stop
only enough to release the pressure against the Clutch
Shaft. While keeping the pressure relieved, unscrew
the assembled clutch from the Stop as you would un-
screw a nut from a bolt. Expanding the Stop suffi-
ciently to clear the Shaft in a normal manner will dis-
tort the snap ring beyond acceptable limits.
5. Insert the tip of a #1 Phillips head screwdriver into
the notch in the motor end of the Clutch Adjusting
Nut Lock (69) and one of the notches in the Clutch
Adjusting Nut (68) and turn the screwdriver counter-
clockwise (as you would to remove a screw) to back
the Nut off the Clutch Shaft. Insert the screwdriver
far enough to create a gap between the Nut Lock and
Adjusting Nut.
6. Remove the Nut Lock, Clutch Spring (70), Cam Fol-
lower (71) and three Clutch Balls (72) from the
Clutch Shaft.
7. Pull the Clutch Bearing (82) off the spindle end of the
Clutch Shaft.
8. To remove the three Cam Pins (77), position one pin
downward and sharply rap the motor end of the
Clutch Shaft on a workbench mat or a piece of corru-
gated cardboard box. Repeat the process for each of
the remaining two Pins.
9. Using a thin blade screwdriver, spiral the Spindle
Retainer (81) out of the groove in the Clutch Shaft
and pull the Clutch Spindle from the Shaft.
10. Pull the Cam Shaft (78), Cam Block (79) and Reset
Spring (75) from the Clutch Shaft.
11. To remove the six Shutoff Balls (76), insert the shaft
of the Shutoff Spool into the end of the Cam Shaft to
prevent the Balls from becoming lodged in the central
opening. Position one of the shutoff ball openings
downward and sharply rap the Cam Shaft on a work-
bench mat or a piece of corrugated cardboard box.
Two Shutoff Balls are installed in each hole. Repeat
the process at the other two locations for the remain-
ing four Balls.
