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 specic 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 repellent, 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 conned space and a dust mask for
dusty operations. Hard hats, face shields, safety shoes, respirators, etc. should be
used when specied or necessary. Keep a re extinguisher nearby.
• Before tool is connected to pressurized air, check that the throttle operates freely in
both directions and returns to the “OFF” position when released. Before changing
sockets or performing service on the motor, make sure that the air line is shut off and
drained to prevent operation if the throttle is engaged.
• 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.
• 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 inuence of drugs, alcohol or any
medication causing decreased control.
• Maintain Tool Carefully. Keep tools clean for best and safest performance. Follow
instructions for lubrication, maintenance and changing accessories.
• 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.
• Some individuals are susceptible to disorders of the hands and arms when exposed to
task which involve highly repetitive motions or vibration. Those individuals predisposed
to vasculatory or circulation problems may be particularly susceptible. Cumulative
trauma disorders such as Carpal Tunnel Syndrome and Tendonitis can be caused
by repetitions, forceful exertions of the hands and arms. These disorders develop
gradually over periods of weeks, months and years.
• Tasks should be performed in such a manner that the wrists are maintained in a neutral
position, which is not exed, hyper extended, 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,
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.
• The following recommendations will help reduce or moderate the effects of repetitive
work motions and/or extended vibration exposure.
a.) Use a minimum hand grip force consistent with proper control and safe operation.
b.) Keep body and hands warm and dry.
c.) Avoid anything that inhibits blood circulation (ie. Smoking Tobacco, Cold
Temperatures, etc)
d.) Avoid highly repetitive movements of hands and wrists, and continuous vibration
exposure.
• Work gloves with vibration reducing liners and wrist supports are available from some
manufactures of industrial work gloves. Tool wraps and grips are also available from
a number of different manufacturers. WARNING! Proper t gloves are important.
Improperly tted gloves may restrict blood ow to the ngers and can substantially
reduce grip strength.
SAFETY GUIDELINES

OPERATION INSTRUCTIONS
The ET850 is a push-pull type torque controlled rolling motor. It is designed for use with regulated,
ltered and lubricated 90 psig air (measured at the tool inlet). The tool expands to a preset torque, and
then stops. The handle is then pulled away from the tubesheet, operating the motor in reverse and
allowing tool removal from the tubesheet. Any time the operator releases the handle, the motor stops.
Air Supply
The tool is designed to operate on 90-125 psig maximum air pressure. Optimal range is 90-100 psig.
Using 100-125 psig will increase speed but may result in faster wear of expander consumables. The
air pressure should be checked at the tool’s inlet when the tool is running. An automatic in-line lter-
lubricator is required. This will supply tool with clean, lubricated air for optimal performance and tool
life.
The air hose should be cleared of accumulated dirt and moisture. Then pour one half (1/2) teaspoon of
10W machine oil into the tool’s air inlet before connecting the hose to the tool. A new hose should be
similarly lubricated before placing in service. The tool should be cycled several times to disperse the
oil before rolling tubes.
Lubricating The Motor
The in-line lubricator should be regularly checked and kept lled with a good grade of SAE 10W
machine oil. Application of the tool should govern how frequently it is greased.
The gear assembly can be lubricated through an external grease tting. Using a hand-held grease
gun, apply two shots of NLGI No. 2 Moly grease roughly every four weeks. CAUTION: DO NOT OVER-
LUBRICATE. If too much grease is applied, excess grease will be forced into the motor section and
cause poor operation.
Tube Rolling Procedure
NOTE: Always clean the tube sheet hole before inserting the tubes. Use a proper size expander to
ensure that all tubes are expanded to the same wall reduction.
Set the torque setting ring of the control to the correct torque setting for the type and size of tubes
to be rolled. Insert the expander into the quick change chuck on the motor. The motor is turned on
or off by the means of a quick operating sleeve type valve. The direction of rotation of the spindle
is controlled by the position of the lever handle at the rear of the tool. Pushing forward on the lever
handle causes the spindle to turn in a clockwise direction, and pulling back on the lever handle causes
it to run in reverse. The lever handle also acts as a torque reaction handle to assist in absorbing the
torque of the tool.
CAUTION
!
Caution: If the torque control is adjusted over the maximum power output of the tool,
the torque controlled shut off will not function and the tool will operate like a stall
type tool. Also, if the tool is being operated at its upper torque limits, a drop in air
pressure could cause the torque controlled shut off not to function due to a loss of
motor power and the tool will function like a stall type tool. Operational Check: Grip
tool securely and be prepared to counteract stall torque in case the torque control is
improperly adjusted.
