Setup
Speed Selection
DO NOT ATTEMPT TO CHANGE THE SPEED WHILE THE MOTOR IS RUNNING!
This motor is equipped with a mechanical four-speed gearbox. To select high speed, turn both dials
to the position indicated with a single dot. To select low speed, turn both dials to the position indicat-
ed with 2 dots. If the dial will not turn completely, rotate the spindle slightly by hand while still turning
the dial until the gearbox engages and the dial turns the full distance.
Operating this motor in the high speed selection will yield faster RPMs for higher productivity and less
torque than the low speed selection.
If the motor is running in the high speed selection and the torque controller is set at it’s highest limit
setting and the tubes are being under-expanded, switch the motor to the low speed selection and
rerun the torque controller setup. For increased productivity and to keep the motor cool, a higher RPM
setting is recommended.
Connect to Torque Controller
Reference ELC Setup information in TM-71.
To get full use of the torque shut-off feature, this motor must be used with the Elliott Model
ELC110220 Electronic Torque Controller. Connect the power cord on the motor to one end of the
included adapter cord and then connect the 7-pin connector on the adapter cord to the torque con-
troller receptacle. The controller will automatically detect that the motor is 220V. (Note: The operat-
ing voltage must correspond with the voltage indicated on the motor’s name plate. 99400-220 motors
designed for 220V can be used with 240V as well.
Be sure to familiarize yourself with the ELC110220 Operating and Maintenance Instructions (TM-71).
Handle
To rotate the handle:
1. Disconnect motor from any power source.
2. Remove carbon brushes (reference pg. 10 “Brush Replacement”).
3. Remove (4) front screws (Item 23).
4. DO NOT separate the gearbox (Item 70) from the gearbox plate (Item 18). Doing this may
void the warranty.
5. Separate gearbox plate (Item 18) from motor housing (Item 12) by no more than what is needed
for rotation (approximately 0.25”).
6. Rotate the handle to desired position.
7. Replace (4) front screws to secure the gearbox plate to the motor housing.
8. Replace carbon brushes (reference pg. 10 “Brush Replacement”).
NOTICE
NOTICE: Before rotating the handle, read all
documentation below. Failure to do so may
result in actions that void the warranty. .

Troubleshooting Electric Rolling Motors
Symptom Possible Causes Solution
Motor won’t run.
Loose plug connections. Ensure all plug connections are secure.
Motor voltage doesn’t match power source
voltage.
Ensure that motor voltage matches the volt-
age of the power source.
Torque controller is in “Auto” or “Assisted”
mode & is waiting for additional input.
Check the torque controller dialog
screen & enter info required.
Motor will not shut off at
controller setting.
Limit setting on the torque controller is set
too high. Recalculate or reduce limit setting.
Torque required exceeds motor capacity. Set motor speed (if 2 or 4-speed) to lower
speed or switch to larger motor.
Motor set at low speed setting
(2-or 4 speed motors only). Set motor to high speed setting.
Motor is too large for application. Switch to a smaller motor.
Trigger switch needs repair. Replace the trigger switch.
Motor needs assessed by repair specialist. Have the motor serviced by an
authorized repair specialist.
Motor runs hot.
Motor is operating at high temperatures and
is hot to the touch.
Run the motor outside of the tube in free
speed for 3 to 5 minutes to increase motor
air ow and decrease motor temperature.
Ensure the air vents on the motor cap are
rotated to the 12 o’clock and 6 o’clock
positions.
Motor is operating at or above
its max. amperage rating.
Set motor speed (if 2-or 4 speed) to lower
gear or switch to larger motor.
Ambient temperature are high. See Care & Maintenance on page 9.
Air supply is being obstructed.
Check motor’s air vents for debris
or obstruction.
Ensure operator is not obstructing vents
with hand during operation.
Motor needs assessed by repair specialist. Have the motor serviced by an authorized
repair specialist.
Motor will not
auto-reverse.
Loose plug connection. Ensure plug connection to torque controller
is secure.
Motor is not auto-reversible Motor must be manually reversed.
Motor is losing power.
Carbon brushes need replaced. Replace brushes. See “Brush Replace-
ment” on page 10.
Proper amperage is not reaching motor. Ensure power cord is proper length and
gauge.

Care & Maintenance
Environments with high ambient temperatures require closer attention to care and use. In order to
achieve optimal motor performance consider the following:
• Clean Power–The use of a reliable, consistent power supply will help minimize voltage uctuations
that can be harmful to the motor.
• Ambient Temperature–As the ambient temperature rises, so does the need for cooling. When used
in high ambient temperature conditions, operators should run the motor under no load for 10 to 15
seconds periodically during the shift to enable ambient air to pass through the motor and cool the
internal parts. Frequency and duration of cooling periods are dependent on the ambient tempera-
ture. If using in conjunction with Elliott ELC110220, this practice will not adversely affect the perfor-
mance of the controller. If the motor becomes hot to the touch, run the motor outside of the tube in
free speed for 3 to 5 minutes to increase motor air ow and decrease motor temperature.
• Cooling Motors–In the event that conditions are so extreme that the cooling recommendation above
is not sufcient, operators should consider implementing a multiple motor system where motors
are run for a short period of time then allowed to rest while a secondary motor is put into service.
Alternating motors in this manner will allow the motor to cool and avoid damage due to overheating.
• Internal Operation Temperature–The operating temperature of the internal components must not
reach 284 degrees Fahrenheit (140 degrees Celsius).
To ensure years of reliable operation, follow these simple care and maintenance suggestions:
• Keep the motor clean and free of dirt and other contaminants.
• Do not allow contaminants inside the motor housing. Clean debris out of air vents using com-
pressed air on a daily basis.
• As a best practice the brushes should be inspected approximately every 1,000 expansions. Check
for different wear patterns or wear rates between the brushes, or severe breakdown of edges of
the brush where it contacts the commutator. It is normal for the outside of the motor to get warm
in a few minutes under typical usage. However, if the motor shows any signs of the temperature
continuing to rise in particular too hot to touch, see “Ambient Temperature” above and replace the
brushes. In each of these cases it is important to replace the brushes, they should not be reworked.
When the brush lengths are .25” (6.35mm) or less, brushes need to be replaced. (Typically after 100
hours of use). Brushes should be replaced by a maintenance technician. They must be run in by a
20 minute idle run of the tool. Also, the condition of the commutator must be checked. In case of ir-
regular coloring of the individual blades and surface crashes, send the tool to an authorized service
center.

Brush Replacement
When To Replace The Carbon Brushes:
When the brush lengths are .25” (6.35mm) or less, brushes need to be replaced. Brushes are eld-
serviceable components and should be replaced by a maintenance technician.
1. Disconnect motor from any power source.
2. Remove (4) back screws (Item 18) & remove motor cap (Item 17).
3. Lift up the at spring to remove the carbon brush (Item 7) from the brush holder (Item 5).
4. Remove the screw & lock washer holding the wire terminal attached to the carbon brush & de-
tach the carbon brush from the holder.
5. Attach the wire terminal of the new carbon brush with the screw & lock washer. (IMPORTANT:
Ensure that the wire lead on the carbon brush terminal is under the contact washer).
6. Lift up the at spring & insert the new carbon brush into the brush holder & release the at spring
to hold the carbon brush in place.
7. Repeat steps 2 thru 5 for replacing the carbon brush on the other side of the rotor complete
(Item 1).
8. Replace motor cap (Item 17) and (4) back screws (Item 18). Be sure the air vents are located at
the 12 o’clock and 6 o’clock positions (Exception: If handle is installed at the 6 o’clock position,
then air vents will be located at the 3 o’clock and 9 o’clock positions.)
NOTICE
NOTICE: Always remove carbon brushes before
changing the handle position.
