OPERATING CONTROLS AND FEATURES
The Clamping Knob © is used to extend or retract
Clamping Bracket (9) when installing or removing the
machine. See “Installation” instructions for details.
2. The Braided Traction Cord @) is securely attached to
the Accessory Connector © with a special “bowline”
knot. This knot should never be untied or cut off. To
prevent wear and fraying, the machine should be
mounted facing toward the desired direction of pull so
that
the Braided Traction Cord (2) does not contact the
side of the slot from which it extends. Do not use the
machine if signs of wear or fraying are observed on
the Braided Traction Cord @) — consult the factory for
replacement. Read and follow warning on page 1.
The Accessory Connector © is opened by using the
thumb and index finger to “pinch” the two “tabs”
towards each other inside the loop at the end of the
knot. This action opens the Accessory Connector @) to
accept the metal bar or metal ring of the desired
accessory such as Catalog Number SC-31S Spreader
Bar or Catalog Number PT-110 Line-Tite Clamp with
traction cord extension. Close the Accessory Connector
so that both halves engage the desired accessory.
The Max Traction Knob © is conveniently accessible
from either side of the machine. The knob is used to
determine the maximum traction force to be applied
during the Hold phase and should be turned so that the
white indicator line corresponds to the prescribed
traction force between 10 and 100 pounds (4.5 and 45
kilograms) on the Max Traction dial.
The Max Traction dial settings in pounds are marked in
cream colored numerals next to the graduations on the
outside edge of the curved scale. Settings in kilograms
are marked in orange colored numerals next to the
graduations on the inside edge of the curved scale. The
high
traction range above 40 pounds (18 kilograms) on
the curved scale is colored yellow as a caution
reminder to the operator — see the description of High
Traction Display for details.

CAUTION!
To interrupt or stop treatment, turn Treatment Timer
Knob (7) to zero and wait until all tension has
released automatically before using the Cord Release
Position (5). To prevent damage, NEVER TURN MAX
TRACTION KNOB (a) TO CORD RELEASE POSITION
(5) WHILE TRACTION FORCE IS APPLIED TO
BRAIDED TRACTION CORD (2).
With no traction force applied, the length of the Braided
Traction Cord (2) may be adjusted by turning the Max
Traction Knob (4) past the 10 pound (4.5 kilogram)
setting to Cord Release Position (5). (Note: a
mechanical interlock prevents the Max Traction Knob
from being turned past the 100 Pound (45 kilogram)
setting to Cord Release Position ©)
For proper operation, the machine reguires a partial
turn of Braided Traction Cord (2) on its take-up drum.
Therefore, if a longer cord is desired (such as for
lumbar traction), we recommend the use of Catalog
Number PT-110 Line-Tite Clamp with traction cord
extension.
6. In intermittent (rhythmic) traction treatments, the
machine will repeatedly pull to and hold at the
MIN RESET < maximum force indicated by the Max Traction Knob
ER, o, ©, then release to and rest at the minimum force
indicated by the Min Reset Knob (6). The Min Reset
Knob (© is accessible from either side of the machine
and should be turned so that the white indicator line
corresponds to the desired setting between 5 and 50
pounds (2.3 and 23 kilograms).
For proper operation, the Min Reset Knob (6) should be
set approximately 10 pounds (4.5 kilograms) below the
Max Traction Knob settings. See the description of
Min/Max Error Display @) for details on insufficient
differential between Min and Max settings.

As a safety measure and to minimize any apprehension
we recommend that you always give the low voltage
Patient Interrupt Switch (13) to the patient. When the
red button on the end of the switch is pressed, any
applied tension automatically releases gradually. The
operator may conveniently resume a patient interrupted
treatment without the need to change control settings
by turning the Power On/Off Switch (7) “OFF” and
“ON” again. The Patient Interrupt Switch (3) also
functions as a “call button” which enables the patient
to audibly signal the operator for assistance whenever
the red button is pressed.
The Static Traction Mode Indicator is a graphically
displayed orange colored arrow which lights whenever
the Hold Timer Knob is turned to the setting
marked STATIC (provided the power is connected and
switched “ON”). During a static traction treatment, the
machine will pull to and hold at the maximum force
indicated by the Max Traction Knob © for the length
of time indicated by the Treatment Timer Knob (m
(Note: If a sufficient differential has been provided
between Min and Max settings, the Min Reset Knob
and Rest Timer Knob settings will not affect the
machine when operating in the static traction mode).
The Intermittent Traction Mode indicator (as) isa
graphically displayed orange colored arrow which lights
whenever the Hold Timer Knob (16) is turned to any
setting other than the one marked STATIC (provided
power is connected and switched “ON").

The Hold Timer Knob is used to determine either
the static traction mode, or the number of seconds to
hold at the force indicated by the Max Traction Knob
during each cycle of the intermittent traction mode.
During the hold phase of operation, the machine will
automatically compensate for the normal loss of
tension caused by harness stretch and patient
movement. This “top-up" feature maintains the
prescribed maximum traction force indicated by the
Max Traction Knob © (Note: Although the Hold Timer
setting may be changed at will, the new setting will not
be recognized until the next cycle).
The Treatment Timer Knob (7) is used to start the
treatment, determine its length in minutes, and to either
stop or interrupt. Turn the knob so that its white
indicator line corresponds to the desired length of
treatment. The treatment timer is a mechanical clock
that will “count down” to show the treatment time
remaining plus automatically stop the treatment and
ring a bell to signal the operator at zero, The treatment
timer is the control used to start the treatment and the
only one used by the operator to stop or interrupt
treatment. After treatment timer reaches zero, wait
until all tension has released automatically before
using Cord Release Position (5) or removing harness
from patient.
The Rest Timer Knob is used to determine the
number of seconds to rest at the force indicated by the
Min Reset Knob (6) during each cycle of the
intermittent traction mode. (Note: Although the rest
timer setting may be changed at will, the new setting
will not be recognized until the next cycle.)
The Caution Conditions Section of the instrument
panel features four graphic displays which will light
(provided power is connected and switched “ON") only
upon the occurance of a condition requiring the
operator's attention.

As a caution reminder to the operator, the yellow
colored High Traction Display (20) lights and remains
lit whenever the Max Traction Knob (4) setting is
increased to the high traction range above
approximately 40 pounds (18 kilograms). As an
additional caution reminder, the display will also flash
and audibly signal five times at the start or resumption
of a treatment in the high traction range.
The yellow colored Min/Max Error Display @) flashes
and audibly signals the operator (in either static or
intermittent traction modes) when the machine pulls to
the maximum force indicated by the Max Traction Knob
without sufficient differential between the Min and
Max settings. When this condition occurs, the
treatment is automatically interrupted and the tension
gradually releases. Although the machine will function
normally at less differential, we recommend adjusting
the Min Reset Knob (6) to at least 10 pounds (4.5
kilograms) below the Max Traction Knob © setting.
After correction, the treatment may be resumed without
the need to change other control settings by turning the
Power On/Off Switch O) “OFF” and “ON” again.
The red colored Safety Interrupt Display (22) flashes
and audibly signals the operator when the machine’s
secondary safety circuit is actuated. When this
condition occurs, the treatment is automatically
interrupted and the tension gradually released.
The secondary safety circuit is adjusted to actuate
during treatment if the traction force applied exceeds
the Max Traction setting tolerance. The two common
causes for this condition during treatment are either the
operator turned the Max Traction Knob to a setting
below the amount of traction force which was already
applied, or the patient moved away from the machine in
such a manner as to apply more traction force than was
indicated by the Max Traction Knob (a). A third
possible cause of the condition is an internal switch
malfunction requiring repair service. The treatment may
be resumed without the need to change control
settings by turning the Power On/Off Switch @ “OFF”
and “ON” again. Safety interrupt on each resumption
without “operator adjustment” or “patient movement”
indicates a switch malfunction. Discontinue using the
machine immediately. Disconnect the AC power cord
from the AC outlet and consult the factory for repair
service.

RECOMMENDATIONS
A. As with the safe use of any motorized equipment, your TRU-TRAC™ should only be used with a
responsible adult in attendance. For that reason, do not attempt to put yourself in traction with this
machine.
B. In the event of a loss of power to the machine, traction force should only be released by gradually
lengthening the patient harness adjustment straps. To prevent damage, NEVER TURN MAX
TRACTION KNOB © TO CORD RELEASE POSITION © WHILE TRACTION FORCE IS APPLIED TO
BRAIDED TRACTION CORD (2).
C. If you are having difficulty operating your TRU-TRAC™ after carefully reviewing this guide, contact
your supplier for assistance. If they are unable to resolve the problem, consult a Customer Service
Representative at the factory.
D. DO NOT USE any accessory or other device with your
TRU-TRAC™ which requires the removal, modification,
or replacement of the acorn nuts shown in the
illustration to the left. Either overtightening of the
original acorn nuts, or overtightening of any
replacement/adaptor nuts can deform the housing and
interfere with the safe and proper operation of the
moving parts inside the housing of the TRU-TRAC™.
Read and follow warning on page 1.
NOTE: The TRU-TRAC Brand “TD-9000” 3-Dimensional
Cervical System may be an exception. If so, follow
accompanying TD-9000 installation instructions
carefully.
Page 14 No. 990002C (10/85)

HOW TO START AND STOP OR INTERRUPT A TREATMENT
Traction treatments may be given only by or on order of a licensed practitioner. TRU-TRAC Therapy
Products Inc. does not recommend the use of any specific traction force or timer settings. Any
settings mentioned in the product instructions are for illustrative purposes only. Reprints of pertinent
clinical studies and medical papers are available upon request without charge in either compendium
or unabridged form.
A. It is usually easier to align the harness on the patient while they are standing and then tighten the
harness after positioning them relative to your TRU-TRAC™. Follow the fitting instructions supplied
with the patient harness.
B. Position the patient on the TRU-TRAC brand table or chair in accordance with the instructions
supplied with those products. Note that the TRU-TRAC™ should be mounted facing the intended
direction of pull so that the Braided Traction Cord @ does not contact the side of the slot from
which it extends.
C. Tighten any slack in the harness so that it fits the patient securely.

IN CASE OF TROUBLE
BEFORE CALLING FOR SERVICE CAREFULLY REVIEW THIS GUIDE
In the event you are still unable to correct the problem, consult the Customer Service Department at the
factory for all repair service and to arrange for a loaner/rental unit. Be sure to specify your model number,
serial number, and a detailed description of the problem encountered.
A. | Machine will not pull and neither Static nor Intermittent Traction Mode Indicator or (15) is lit:
1. Power Supply Cord (Male End) (1) is not connected to electrical outlet.
2. Electrical outlet is not operable — try connecting another electrical appliance known to be in an
operable condition (such as a lamp) to the same outlet to check this possibility. Check circuit
breaker or fuse at building power panel.
3. If your electrical outlet is fitted with a GFI (ground fault interrupt) device, it may need to be reset.
4. Power Supply Cord (Female End) 02) is not fully engaged in Power Supply Receptacle ©.
5. Power On/Off Switch (7) is turned “OFF”.

than “5” minutes.
3. The number of seconds indicated by the Rest Timer Knob have not elapsed.
4. The Rest Timer Setting was changed and the new setting will not be recognized until the next
traction cycle.
5. A Min/Max Error, Safety Interrupt, or Patient Interrupt has occurred as indicated by lit displays (21) 5

Interrupt Switch (3) and cord assembly may be unplugged or not fully inserted into its receptacle.
7. The Braided Traction Cord @ is extended from the slot to its full length — allow some of the cord to
retract back into the unit and use a Catalog Number PT-110 Line-Tite Clamp with traction cord
extension.

5. There has been a loss of power to the machine — see possible causes following problem “A” above.
6. Another apparatus such as a short wave diathermy is in use too near the traction machine and
is affecting its timers.
D. | Machine pulls repeatedly while in Hold Phase.

this type of problem, simply avoid the concurrent use of diathermy devices in the vicinity of the
traction machine.
