OPERATION

•This TREADMILL is intended for home use only.

Be sure your TREADMILL is sitting on alevel surface.

The TREADMILL should be plugged into a three prong (grounded) outiet in a 115/120 volt-60 Hz AC circuit separate

from all other appliances -see GROUNDING INSTRUCTIONS.

GROUNDING INSTRUCTIONS

This product must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance

for electric current to reduce the risk of electric shock. The plug must be plugged into an appropriate outlet that is

properly installed and grounded in accordance with all local codes and ordinances.

WARNING -- Improper connection of the equipment-grounding conduc-

tor can result in a risk of electric shock. GROUNDED

OUTLET

Check with a qualified electrician or serviceman if you are in doubt as to whether

the product is properly grounded. Do not modify the plug provided with the product GROUNDED

-- if.it will not fit the outlet, have a proper outlet installed by a qualified electrician. PIN __

This product uses a nominal 120 volt circuit and has a grounding plug that looks

similar to the plug illustrated.

No plug adapter should be used with this product. __,_pL :G_ _

The use of an extension cord with this product is not recommended, but if an

extension cord is needed, use a short (less than ten feet), heavy gauge (14 gauge U

or better) extension cord with a three prong (grounded) plug and receptacle.

OPERATION

The FITNESS INDEX button tracks your fitness level

with computer calculated fitness rating. The Fitness

Computer will calculate your fitness rating from 0 (Poor)

to 10 (Good).

Your level of fitness is determined by your pulse rate.

As you fitness level increases you will find that you will

need to walk or jog faster to stay in the pulse range you

have chosen. The FITNESS INDEX button gives you

feedback to your increasing fitness level.

NOTE: You must stay consistant in your workouts in

order to get an accurate and consistant fitness rating.

Refer to "USING THE PULSE EARCLIP" section and

attach earclip as directed.

After completing your workout, remain stillwith earclip

attached.

Press FITNESS INDEX button. 0:60 will appear in

TIME display area. Time will

count down to 0:00 and Fit-

ness Computer will calcu-

late your fitness rating from

Oto 10.

Using The PULSE EARCLIP

CA UTION -- This pulse earclip is not a medi-

cal device. Readings may not always be accurate. Best

readings may be obtained in a still, relaxed position.

IMPORTANT-- When exercising in a vig-

orous manner the erratic movement of the PULSE

EARCLIP or CABLE may cause the "P" to appear in the

PULSE window indicating incorrect pulse readings. Try

to keep the PULSE EARCLIP and CA BLE from uneces-

sary movement when exercising.

1. Insert EARCLIP PLUG into EARCLIP RECEPTACLE

on back of CONSOLE - see DETAIL "A".

2. Attach STRAIN RELIEF CLIP to your cellar or other

piece of clothing - see DETAIL "B".

]Y..Q.TJ_:EARCLIP CABLE must not be aflowed to be

in a strain.

3. Massage EARLOBE to increase circulation.

4. Attach EARCLIP to EARLOBE in a vertical position -

see DETAIL "C".

5. When exercise has been completed remove EAR-

CLIP from earlobe and clip it to EARCLIP CABLE.

TROUBLESHOOTING

Console and Motor System

Four components make up the console and motor system; FAST TRAC FITNESS COMPUTER, mounted on the

console, INTERFACE BOARD, mounted on the bottom motor cover, MOTOR CONTROLLER and MOTOR mounted

to the front right rail.

Console

The CONSOLE contains the FAST TRAC FITNESS COMPUTER which controls the speed and elevation of the

treadmill. It also displays time, speed, distance (miles and laps), calories, and pulse.

The time will display from 0:00 to 99:00 inone minute increments. The speed will read between .5 and 10.0 at .1 MPH.

The distance is indicated in miles (0 to 49 3/4) and laps (0 to 199). The calories will be displayed from 0 to 990 in 10

calorie increments.The pulse displays your heart rate from 90 to 180 in 1 beat per minute increments. The time,

distance, calories, and pulse desired can be programmed into the fitness computer.

Interface Board

The interface board isan electronic circuitboard mounted tothe bottom motor cover- see FIGURE 3. With the treadmill

plugged in and the power key inserted the DC voltage from PI to N on the interface board should be 13.6 VDC. The

voltage from P2 to N will vary with the speed;

0 MPH - 0 VDC

.5 MPH - .68 VDC

10.0 MPH - 12.3 VDC

The voltage across the capacitor, Cl, should be 9.56 VDC. When the treadmill is runningat .5 MPH the motor should

maintain 250 RPM, at 10.0 MPH the motor should maintain 5200 RPM.

Motor Controller

The motor controller is an electronic circuitboard mounted to the right rail infront of the motor -see FIGURE 4. From

a grounded wall outlet the motor controller receives 120 VAC and converts it to variable DC 0 to 90 V. The monitor

and interface board adjust the output of the motor controllerfrom 0 to 90 volts.The motor controller senses the motor

speed by the tachometer. The tachometer on the motor tells the motor controller itsspeed. If a load isplaced on the

treadbelt the motor controller compares the set point of the speed control to the tachometer and makes adjustments

to the DC output voltage to the motor keeping the treadbelt runningat a fixed speed. For example, the output voltage

will be 9.5 volts at .5 MPH, as a person steps on the treadbelt the output voltage increases to compensate for the

extra motor loading, keeping the treadbelt runningat .5 MPH.

Motor

This treadmill uses a2HP DC motor - see FIGURE 5. When the voltage to a DC motor is changed the speed will

vary accordingly. The motor receives 0-90 VDC from the motorcontroller. The voltagefrom M1to M2whilethe treadmill

is running at 10.0 MPH should not exceed 90 VDC and the shouldbe turningat 5200 RPM. The motor has an integral

tachometer which tells the motor controllerthe motor'sspeed. The tachometer consistsof a coil ofwire inside a plastic

housing. A permanent magnet mounted to the motor, behind the fan, rotates inside the tachometer coil generating a

low voltage, proportional to the motor speed.

.66 VAC -250 RPM

9.40 VAC -5200 RPM

The tachometer coil should be 300 ohms 25 ohms.

Note: The tachometer can be measured with an ohmmeter only when disconnected from the motor controller.

The winding resistance should bevery low, approximately 1 ohm. Test each winding in the armature (the rotatingpart

inside the motor) by slowly rotatingthe motor shaft 1 complete revolution. All windings should be less than 2 ohms.

Note: The windings of the motor can be measured with an ohmmeter only when disconnected from the motor

controller.
