BATTERY TESTING
For “B” battery powered chairs, determine if the battery on the device is charged and in good working
condition.
- Using a voltage meter, check the voltage of the battery. A fully charged battery should have a
reading of over 26 volts.
- The green light on the pendant will turn to amber if the battery is near or below 24.6 volts.
- If the battery is showing a charge of above 24.6 volts but the chair is not functioning, the battery
testing protocol can be used to determine if the battery is in need of replacement. The battery
testing protocol can be found by following this link: "B" Battery Testing Protocol
For “A” (AC Powered) chairs, ensure the device is plugged into a working 120V outlet.
- AC powered chairs require working batteries even when plugged into an AC outlet
- For testing AC Powered chairs built during or after February of 2012 email
techservice@wincomfg.com
and request the installation and maintenance manual (IM TMS-1066-
03). This manual describes how to change the battery pack but can also be used to remove the
pack to test the batteries.
- For testing AC powered chairs built prior to February of 2012 follow this link: "AC" Battery Testing
Protocol
Once you have determined that the battery is charged and in good working condition, use the
following instructions to continue troubleshooting the device or return to the “General Issues”
page.

Trouble-Shooting Guide
STRETCHER-CHAIR HAS NO FUNCTIONS
1. Trace the cord from the pendant back to the control box and look for any signs of cuts or pinch
points in the cable. If the cord is damaged at any point, replace the pendant.
2. Does your TMM Series Stretcher-Chair have an old or new style pendant?
3. If your TMM Series Stretcher-Chair has an older style pendant, we recommend purchasing a
new pendant. Visit the Technical Service & Parts page of our website or contact 0ur
Customer
Service Department for the appropriate part number and / or pricing.
4. If another pendant is available, plug the working pendant into the control box and test the
functions of the device. NOTE: Pendants from other TMM Series Stretcher-Chairs may be able
to be used to troubleshoot the issue. Both devices must have the same or similar control boxes.
5. If switching pendants resolved the issue, contact our Customer Service Department
for a
replacement pendant.
6. If another pendant is not available, the issue may be either the pendant or the control box. A
replacement pendant and control box may be purchased together. Unused items may be
returned for a refund (please refer to section 6 of Winco Mfg., LLC’s Terms & Conditions
.)
7. Once the item(s) are received, plug the new pendant into the control box and test the functions
of the stretcher-chair.
8. If the replacement pendant did not resolve the issue, remove and replace the control box.
Control box installation and maintenance instructions should be included with the new control
box. If the instructions are not available, you may download a copy via the
Product Resources
Page of our Website or by contacting our Customer Service Department.
You may now continue troubleshooting your device or return to the “General Issues” page.

ONE OR MORE FUNCTIONS HAVE STOPPED FUNCTIONING
1. At this point, one of three possible components may have failed: the control box, the actuator /
motor, or the pendant.
2. Access the control box in the base of the chair.
3. Refer to the control box wiring diagrams by following this link: “Control Box Wiring
”.
4. Determine the ports on the control box that operate the functioning and non-functioning sections of
the chair.
5. Switch the plugs in these two ports
• Example for KOM control box: if the back section of the chair is not working and the leg section
of the chair is working, switch the cords in ports #2 and #3.
6. The buttons on the pendant will now be switched. The buttons that controlled the non-functioning
portion of the chair will now be controlling the functioning portion of the chair.
• Following example from step 5: the buttons for the back section on the pendant will now be
controlling the leg section and the buttons for the leg section will now be controlling the back
section.
7. If the motor is now working, then you have eliminated the motor as the possible failed component.
8. If the motor is still not working, then the motor has likely failed and may need to be replaced. If this
is an X-Series chair built prior to February of 2012, additional troubleshooting can be done by
following this link: X-Series Chair built prior to February of 2012
. If this is not an X-Series chair built
prior to 2012, visit the Technical Assistance & Parts page of our website or contact 0ur Customer
Service Department for the appropriate part number and / or pricing.
9. If the motor is not the failed component, then the issue is either the control box or the pendant. If
another pendant is available, plug it into the control box of the non-working device to test the
functions. If the alternate pendant is still not working or if another pendant is not available, a
replacement pendant and control box may be purchased together. Unused items may be returned
for a refund (please refer to section 6 of Winco Mfg., LLC’s Terms & Conditions
10. Once the item(s) are received, plug the new pendant into the control box and test the functions of
the stretcher-chair. If the replacement pendant did not resolve the issue, remove and replace the
control box. Control box installation and maintenance instructions should be included with the new
control box. If the instructions are not available, you may download a copy via the
Resources Page of our Website or by contacting our Customer Service Department.

TALL (T) CHAIR IS NOT GOING TO FULL HEIGHT
1. Tall lift columns have two (2) actuators inside the tower that function simultaneously to raise and
lower the stretcher-chair, however each actuator is controlled by individual ports on the control
box.
2. First make note of which section of the column is not moving. This could be the lower section or the
upper section.
3. Refer to the control box wiring diagrams by following this link: “Control Box Wiring
”
4. For KOM control boxes, switch the cords in ports #1 and #4. For VCU control boxes switch the
cords in ports #1 and #2.
5. Use the pendant to raise and/or lower the chair.
6. If the section of the column that was not functioning is now functioning, the problem is either in the
button on the pendant or the port in the control box. Call or email technical service for part number
and price.
7. If the same section of the column is still not working and the chair has a KOM control box, then the
issue is likely in the column. Call or email technical service for part number and pricing. If the chair
has a VCU control box, then continue to step #8.
8. VCU control boxes require adapter cables for the columns. One of these adapter cables may be
faulty, pinched, or severed. Inspect the cables for damage. See picture of cable below. Call or email
technical service for part number and price if cable is damaged.
9. If the cables appear to be in good condition, switch the column cables in the adapter cables.
10. If the same section of the column is not working, the issue is in the column. Call or email technical
service for part number and price.
11. If the section of the column that was not functioning is now functioning, the problem is in the
adapter cable. Contact 0ur Customer Service Department

TMM3 (VIDEO FLUOROSCOPY) CHAIR WILL NOT GO DOWN
1. TMM3 chairs are designed so the chair seat cannot be lowered while the upper portion of the chair
is rotated. The upper portion of the chair must be in line with the base for the chair to be lowered.
2. If the seat cannot be lowered, rotate the upper portion of the chair then back to straight with the
base again and attempt to lower the chair.
3. If step #2 did not fix the issue, find the limit switch under the seat of the chair and ensure that it is
not activated (the button is not pushed in).
4. If the limit switch appears to be working properly, access the control box in the base of the chair
and unplug the cord in port #4. WARNING! This will disable the limit switch allowing the chair to
be lowered while the seat is rotated. Severe damage to the chair may occur while lowering the
seat while in the rotated state. This should only be disabled temporarily for troubleshooting
only!
5. With port #4 unplugged, attempt to lower the chair slightly.
6. If the chair goes down, the limit switch is faulty and requires replacement. Call or email technical
service for part number and price.
7. Plug the cord back into port #4.
8. If the column still does not go down, follow this link to “
One or more functions have stopped
functioning” to continue troubleshooting the chair.
You may now continue troubleshooting your device or return to the “General Issues” page.

X-SERIES CHAIR WILL NOT TILT OR ONLY TILT IN ONE DIRECTION
1. The tilt feature on X-series chairs is limited to a certain amount of tilt forward and backward
depending on other included features.
2. The amount of tilt is controlled by limiting switches behind a small cover on the left side (patient’s
left) of the chair under the seat section. See Picture below
3. One of these limit switches may not be working properly. If one of the switches is fixed in the actuated
position, the tilt motor will not move in that direction.
4. Using a Phillips head screwdriver, remove the cover and attempt to manually actuate the switches.
5. An audible click should be able to be heard when the switch is activated and released.
6. If the one of the switches is not de-activating (button is not “popping” back up), then the switch is
faulty and needs to be replaced.
7. Call technical service for part number and price.
WARNING! – THE DEGREE OF TILT IS SET AT THE FACTORY AND SHOULD NOT MODIFIED.
MODIFYING THE AMOUNT OF TILT MAY CAUSE INTERFERENCE BETWEEN COMPONENTS ON THE
CHAIR CAUSING DAMAGE TO THE COMPONENTS OR THE DEVICE.

Trouble-Shooting Guide
Note: This portion of the troubleshooting guide should only be followed after performing the “
ONE OR
MORE FUNCTIONS OF THE STRETCHER-CHAIR HAVE STOPPED FUNCTIONING” portion of this guide
and the motor has been determined as the issue.
1. X-series chairs built prior to February of 2012 include two (2) additional phono jack plugs under the
seat section at the back of the chair. Trace the pendant cord until it enters the cover at the back of
the chair. Remove this cover to reveal the plugs. There are 3 plugs in series behind the cover.
These plugs control the tilt, leg, and back motors.
2. These 3 plugs may be interchanged to determine the faulty part in the chair.
Leg
Motor
Motor
Motor
3. Note which motor is currently functioning and which is not currently functioning.
4. Unplug the motor that is not functioning and plug this motor into the port for the functioning motor.
• Example: if the leg motor is not functioning and the back motor is functioning, switch the
plugs in the middle and far right ports. The buttons for the leg section on the pendant
should now operate the back section.
5. If the motor that was not functioning before is still not functioning, then the issue is with the motor.
Call technical service for part number and price.
6. If the motor that was not functioning before is now functioning, then the motor is not the issue.
7. Check for damaged or disconnected wires leading to the faulty plug.
8. Call technical service for further instructions and part number and price.
