SAFETY GUIDELINES
Read and save all instructions. Before use, be sure everyone using this machine reads and
understands this manual, as well as any labels packaged with or attached to the machine.
• Know Your Elliott Tool. Read this manual carefully to learn your tool’s application and
limitations as well as the potential hazards specic to this tool.
• Avoid Dangerous Environments. Do not use power tools in damp or wet locations
• Keep Work Area Clean and Well Lit. Cluttered, dark work areas invite accidents.
• Dress Properly. Do not wear loose clothing or jewelry. Wear a protective hair covering
to contain long hair. It is recommended that the operator wear safety glasses with
side shields or a full face shield eye protection. Gloves and water repellant, nonskid
footwear are also recommended. Keep hands and gloves away from moving parts.
• Use Safety Equipment. Everyone in the work area should wear safety goggles or
glasses with side shields complying with current safety standards. Wear hearing
protection during extended use, respirator for a conned space and a dust mask for
dusty operations. Hard hats, face shields, safety shoes, respirators, etc. should be
used when specied or necessary. Keep a re extinguisher nearby.
• Keep Bystanders Away. Bystanders should be kept at a safe distance from the work
area to avoid distracting the operator and contacting the blade.
• Use The Right Tools. Do not force a tool or attachment to do a job or operate at a
speed it was not designed for.
• Use Proper Accessories. Use Elliott accessories only. Be sure accessories are properly
installed and maintained.
• Repetitive Motion. Repetitive work motions and/or vibration can injure hands and
arms.
• Entanglement Risk. Use minimum hand grip force consistent with proper control and
safe operation.
• Check for Damaged Parts. Inspect guards and other parts before use. Check for
misalignment, binding of moving parts, improper mounting, broken parts or any other
conditions that may affect operation. If abnormal noise or vibration occurs, turn the
tool off immediately and have the problem corrected before further use. Do not use a
damaged tool. Tag damaged tools “Do Not Use” until repaired. A damaged part should
be properly repaired or replaced by an Elliott service facility. For all repairs, insist on
only identical replacement parts.
• Keep Hands Away from All Moving Parts.
• Do Not Overreach. Maintain Control. Keep proper footing and balance at all times.
• Stay Alert. Watch what you are doing, and use common sense. DO NOT use a
tool when you are tired, distracted or under the inuence of drugs, alcohol or any
medication causing decreased control.
• Maintain Labels and Nameplates. These carry important information and will assist you
in ordering spare and replacement parts. If unreadable or missing, contact an Elliott
service facility for a replacement.

• These tools are designed to operate on 90 psi (6.2 bar) maximum air pressure. If the
tool is properly sized and applied, higher air pressure is unnecessary. Excessive air
pressure increases the loads and stresses on the tool parts, sockets, and fasteners
and may result in breakage. Installation of a lter-regulator-lubricator in the air supply
line ahead of the tool is recommended. Only use approved air lubrication.
• Before the tool is connected to the air supply, check the throttle for proper operation
(i.e., throttle moves freely and returns to closed position). Clear the air hose of
accumulated dust and moisture.
• Be careful not to endanger adjacent personnel. Before removing a tool from service or
changing sockets, make sure the airline is shut off and drained of air. This will prevent
the tool from operating if the throttle is accidentally engaged.
• It is essential for safe operation for any operator of a rolling motor to use good
balance, sure footing, and proper posture in anticipation of a torque reaction. Insure
that the operator’s hand will not be wedged or pinched between the work and the tool
when operating. Always use ambient light to ensure safe operation.
• Higher torque right angle motors are supplied with splined torque reaction mounting plates
which accept torque reaction bars. These bars can be braced against the work, adjacent tubes,
or other suitable points to absorb and relieve the operator of the torque reaction transmitted
by the tool. Tool balance arms are also available to absorb the torque reaction transmitted by
the tool. Due to their squared design, the reaction mounting plates also prevent the motor from
rolling off the work station, preventing further injury. Tool balance arms are also available to
absorb the torque reaction of the tool for improved ergonomic applications if work is accessible.
CAUTION
!
When using right angle nutrunners, be sure the throttle is positioned relative to
the right angle head so the throttle will not become wedged against an
adjacent object in the “ON” position due to torque reaction. The angle head
may be repositioned with respect to the lever (on tools with levers) to
accommodate proper location for task. If tool is to be reversed, locate throttle
lever in a neutral position that will prevent entrapment. Refer to operating
instructions for additional information.
CAUTION
!
Operator must be prepared to resist stall torque until throttle is released. Use of
a torque reaction bar is recommended.
SAFETY GUIDELINES

Stall Torque Right Angle Rolling Motor 7
SAFETY GUIDELINES
WARNING
!
REPETITIVE MOTION:
Repetitive work
motions and/or
vibration can injure
hands and arms.
Tasks should be performed in such a manner that the wrists are maintained in a neutral position, which
is not exed, hyperextended or turned side to side.
Stressful postures should be avoided and can be controlled through tool selection and work location.
Any user suffering from prolonged symptoms of tingling, numbness, blanching of ngers, clumsiness
or weakened grip, nocturnal pain in the hand, or any other disorder of the shoulders, arms, wrists or
ngers is advised to consult with a physician. If it is determined that the symptoms are job related
or aggravated by movements and postures dictated by the job design, it may be necessary for the
employer to take steps to prevent further occurrences. These steps might include, but are not limited
to, repositioning the workpiece or redesigning the workstation, reassigning workers to other jobs,
rotating jobs, altering work pace, and/or changing the type of tool used so as to minimize stress on the
operator. Some tasks may require more than one type of tool to obtain the optimum operator/tool/task
relationship.
The following recommendations will help reduce or moderate the effects of repetitive work motions
and/or extended vibration exposure:
1. Use a minimum handgrip force consistent with proper control and safe operation.
2. Keep wrists as straight as possible.
3. Keep body and hands warm and dry.
4. Avoid anything that inhibits blood circulation (smoking tobacco, cold temperatures,
certain drugs, etc.)
5. Avoid highly repetitive movements of hands and wrists and continuous vibration
exposure.

OPERATION INSTRUCTIONS
WARNING
!
HIGH TORQUE TOOL: Torque
reaction bar is highly
recommended.
NOTE: The reaction bracket, PN: 445-6001, must fully engage the spline on the right angle head.
Position the bracket forward on the small diameter of the head and then move it rearward to engage
the spline. Securely tighten screws and jam nuts.
NOTE: USE ONLY SOCKETS APPROVED FOR POWER TOOL SERVICE.
CAUTION
!
ALWAYS WEAR APPROVED EYE PROTECTION. (See the latest edition of ANSI
Z87.1 American National Standard for Occupational and Educational Eye and
Face Protection). Position exhaust deector 180º away from face, eyes, etc.
CAUTION
!
READ, UNDERSTAND, AND PRACTICE the requirement of ANSI B186.1, Safety
Code for portable air tools. Standards are available from the American National
Standards Institute, Inc. 1430 Broadway, New York, NY 19918.
The Right Angle Rolling Motor is designed to operate on 90 PSI (t2 bar) air pressure using a ½” hose
up to 8 ft. in length. The Right Angle Rolling Motors are designed to operate on 90 PSI air pressure,
but do not depend on controlled air pressure to maintain accurate torque. Accurate torque is achieved
by setting the clutch to the desired torque on the application. The tool will shut off automatically at the
torque. Releasing the throttle will allow the tool to reset for the next cycle.
Motor Activation
The right angle nutrunner has a lever style throttle. The lever style is activated by simply pressing down
the lever and is de-activated by releasing the lever.

OPERATION INSTRUCTIONS
CAUTION
!
If the motor has stalled, do not attempt to apply additional torque by rotating
the motor as if it were an air ratchet. This will break the rotor paddles and may
damage the motor cylinder.
Operational Check
Grip tool securely and be prepared to counteract stall torque in case clutch is improperly adjusted.
Use proper reaction bar.
Air Supply
An automatic in-line lter-lubricator is highly recommended. This will supply the tool with clean, dry,
lubricated air; keep it in sustained operation; and increase tool life. A mesh screen is supplied in the
motor to help prevent debris from entering motor. This should be removed and cleaned regularly.
For maximum performance, use a ½” I.D. air hose no longer than 8’ in length. If additional length is
required, a ¾” or larger hose should be connected to the ½” hose. The air hose should be cleared
or accumulated dirt and moisture, then one (1) teaspoon of pneumatic oil or a good grade of 10W
machine oil should be poured into the tool’s air inlet before connecting the hose to the tool. Always
position air hose as to prevent it from being crushed or pose a threat as a trip hazard.
Lubrication
The in-line lubricator should be checked and lled regularly with a good grade of 10W machine oil, as
well as, set to provide 2-3 drops of oil per minute.
Safety Check
After repair or replacement of parts, tools equipped with an automatic shutoff device should be tested
to verify that they are functioning properly.
WARNING
!
ENTANGLEMENT RISK:
To prevent hand entrapment from
torque reaction, the square drive
should be positioned from the
throttle as shown below.

MAINTENANCE INSTRUCTIONS
The proper performance and service life of every machine depends on how well it is maintained.
The following should become a regular routine of operations.
1. It is recommended that the right angle gears receive a generous amount of No. 2 moly
grease through the grease plug (located on top of right angle head) after 40 hours of
operation.
2. A wire mesh screen is included in motor to prevent introduction of large debris particles
into the motor. This should be checked regularly and cleaned accordingly.
3. Within the exhaust deector is an exhaust lter. This should be checked regularly and
changed accordingly. This will be dependent on the amount of lubrication used, clean
lines of air, etc.
4. When changing the bearings, it is recommended to use the specially designed Bearing
Seat Tool (445-7005) that is included in the Spares Kit (445SK-ST).
