TEST PROCEDURES
GROUNDED OUTLET TEST
This test is very important for optimal HRC and incline operation.
Set voltmeter for Volts AC
Place 1 lead in the right side of the outlet (hot)
Place 1 lead in the ground plug
A properly grounded outlet will read 110 VAC
AMP DRAW TEST
This test is a good indicator of the wear condition of the belt and deck, and the need for lubrication.
The treadmill circuit breaker will trip at 15 amps, so be sure the voltmeter you are using is rated for at least
15 amps when you are load testing the treadmill. This test can be performed either on one of the AC power
cord leads or on one of the DC motor leads from the PWM to the motor. Testing the amp draw at certain
speeds without load and with load will signal whether higher than normal amp draw is a result of PWM
failure or increased friction from belt and deck wear.
AC AMP DRAW PROCEDURE
This procedure requires an AC clamp-on ammeter. Place the clamp around either of the power cord
leads, black or white. Load test requires a person to walk on the tread belt for 5-10 minutes.
2.5 mph w/out load
2.5 mph with load
4.0 mph w/out load
4.0 mph with load
2.0-2.5 AMPS AC
2.75-3.75 AMPS AC
3.5-4.0 AMPS AC
5.0-7.0 AMPS AC
DC AMP DRAW PROCEDURE
This procedure can be performed with an ordinary voltmeter. (Note: Be sure the voltmeter is rated
to handle 15 DC amps.) Disconnect the red motor lead from MTR1 on the PWM. Connect the
voltmeter to MTR 1 on the PWM and the other voltmeter lead to the red motor lead so that the
voltmeter completes the connection of the PWM to the motor.
2.5 mph w/out load
2.5 mph with load
4.5-5.0 AMPS DC
7.0-8.0 AMPS DC
4.0 mph w/out load
4.0 mph with load
5.0-5.5 AMPS DC
8.5-9.0 AMPS DC
Higher than normal amp draws without load may signal that belt tension is too tight or there is a
problem in the Drive Motor or PWM. Perform the Drive Motor Test and visually check the motor
brushes before replacing the PWM. Higher than normal amp draws with load after normal readings
without load signal belt and deck friction which may require lubrication or replacement.

TEST PROCEDURES
SPEED SENSOR TEST
This test is used to verify sensor operation in conditions of speed fluctuation, E2: Cal error, S4:
Sensor error, E2: Overspeed error or Unsuccessful Calibration.
455 Treadmill
Set voltmeter to volts DC. Treadmill power on and speed at 0 mph
Attach voltmeter leads across outside 2 contacts at J1 on PWM
With magnet in front of sensor, 0 VDC
With no magnet in front of sensor, 5 VDC
Check the sensor on every magnet, adjust sensor until voltage shows
In calibration mode before pressing Start, the tread belt can be moved manually and the Met light
will blink when a magnet is in front of the sensor.
VOLTAGE TO DRIVE MOTOR TEST
This test is used to diagnose conditions of NO Belt Movement, or Speed Fluctuations
Set voltmeter to volts DC and adjust speed on Control Panel to 4 mph
Attach red voltmeter lead to MTR1 on PWM with motor wires attached
Attach black voltmeter lead to MTR2 on PWM with motor wires attached
0 VDC signals no PWM output
166 VDC signals open circuit in motor or motor connection
Operating voltage will lay between 0 VDC and 166 VDC
NOTE: The reason that we do not narrow down PWM output voltage is that the PWM output is a pulse
signal. The sampling rate of the voltmeter used will determine what output voltage the voltmeter is able to
read.

TEST PROCEDURES
DRIVE MOTOR TEST
This test is used in conditions of No Belt Movement.
Unplug treadmill and set voltmeter to volts DC
Disconnect motor leads from PWM
Place 1 voltmeter lead in each motor wire
Gently spin the motor flywheel and check for voltage DC
2-5 VDC means normal motor operation
0 VDC means motor malfunction
DRIVE BELT TENSION TEST
This test is used in front roller replacement and in conditions of belt slipping.
Place two fingers on top of the drive belt halfway between the front roller pulley and the drive motor
pulley.
With moderate pressure push down on belt
If belt deflects down more than 1/8 “, tighten motor mounts
If belt deflects down less than 1/8 “, loosen motor mounts.
It is also possible to twist the belt; you should be able to twist the belt almost to a vertical position
TREADBELT TENSION TEST
This test will address belt slipping and is used in any roller replacement or deck replacement. Ensure that
the drive belt is properly tensioned before adjusting tread belt tension. Belt and deck wear and/or lack of
lubrication can cause the tread belt to show symptoms similar to loose tread belt tension- check these
conditions before adjusting tread belt tension.
Turn treadmill on and adjust speed to 2 mph
Walk heavily on the belt pulling slightly against belt movement
If hesitation or slip is detected, tighten tread belt tension bolts ¼ turn
Repeat until no hesitation or slip is encountered. Check at higher speeds
Tread belt tension is too tight if the belt feels stiff to touch with no give or the belt groans against the rollers.
You should be able to insert your hand between the belt and deck palm up almost to your thumb when the
belt is at proper tension.

TEST PROCEDURES
INCLINE POTENTIOMETER CALIBRATION TEST
This test can correct E1: Minimum conditions and aid in diagnosis of incline problems with finding zero or
target incline.
455:
Set voltmeter to Ohms (Ω) with treadmill unplugged from wall
Place 1 voltmeter lead on pin 3 (Blue) and 1 lead on pin 2 (Orange)
Check for 800 Ohms
455: In calibration mode before pressing Start, the Distance window displays the incline number.
With the treadmill at zero, the number should be between 160 and 180. 0 often indicates a wire
harness misconnection or failure of signal to panel.
As the unit inclines during calibration, watch the numbers in the Distance window, if they do not
increase by at least 60 from the zero value, an E1: Minimum error will result. Then the zero value
may need to be reset to a lower value.
If incline potentiometer needs adjustment, remove swivel pins and use Up and Down keys to make
adjustment. (See diagram on T-6)
VOLTAGE TO INCLINE MOTOR TEST
This test is utilized in conditions of No Incline Movement, Incline Fluctuation, or E1: Minimum.
Set voltmeter to AC volts. To access incline plug, PWM screws may need to be removed.

TEST PROCEDURES
Belt / Deck Wear Test
This is a simple physical test to gauge the general level of friction present between the deck and belt.
1. While the treadmill is not running, inspect the condition of the underside of the tread belt. The fabric
should be soft and porous. If the belt appears glazed- replace the belt.
2. While the treadmill is not running, slide your hand under the belt and feel the surface of the deck.
The deck should feel smooth with no abrasions or scratches.
If any abrasions or scratches are found- replace the deck.
Push Off Test
Place the machine in Calibration mode, elevate to the highest elevation- speed should be set to 0. Stand on
the tread belt positioning yourself close to the console; push off with moderate force. The elevation
combined with your weight and the force of the push should cause the belt to carry you all the way to the
end of the machine*. If the test does not carry you to the end of the machine lubricate the belt using True
Fitness liquid silicone. After lubricating the belt/deck perform the push off test again. If it does not pass the
test after lubricating replace the belt and deck
* Note: Residential treadmills may only carry about ¾ of the distance of the deck due to higher tension on
the belt.
