Operation and Adjustment

The Pre-Lubricated Walking Belt

The walking belt is coated with high-performance lubricant. IMPORTANT: Never apply silicone spray or other substances to the walking belt or platform, as this will deteriorate them and cause excessive wear.

How to Plug in the Power Cord

? DANGER: Improper grounding can increase the risk of electric shock. Consult a qualified electrician if unsure about grounding. Do not modify the plug.

Your treadmill is designed for a nominal 120-volt circuit and has a grounding plug. Sudden voltage changes can damage electronic equipment. Always use a surge suppressor (UL 1449 listed TVSS, 400V or less, 450 joules minimum dissipation, 120V AC, 15 amp rated, with monitoring light). The treadmill is not compatible with GFCI-equipped outlets.

A temporary adapter can be used for 2-pole receptacles if a properly grounded outlet is not available, but it must be connected to a permanent ground (e.g., outlet box cover) and secured with a metal screw. Contact an electrician to verify outlet box grounding.

Diagram Description: Two diagrams illustrate electrical outlet configurations. Diagram 1 shows a properly grounded outlet with a surge suppressor. Diagram 2 shows the use of a temporary adapter to connect a surge suppressor to a 2-pole receptacle.

Console Features

Diagram Description: Shows the latch knob being released and the frame being lowered.

Troubleshooting

Most problems can be solved with these steps. If further assistance is needed, see the front cover.

Problem: The power does not turn on

• Ensure power cord is plugged into a surge suppressor, and the suppressor is plugged into a properly grounded outlet (see page 14). Use only compatible surge suppressors.
• Ensure the key is inserted into the console.
• Check the reset/off circuit breaker. If tripped (protrudes), wait five minutes and press it back in.

Diagram Description: Shows the circuit breaker in "Tripped" and "Reset" positions.

Problem: The power turns off during use

• Check the reset/off circuit breaker. If tripped, wait five minutes and press it back in.
• Ensure the power cord is plugged in. If it is, unplug it, wait five minutes, and plug it back in.
• Remove and reinsert the key into the console.
• If the treadmill still won't run, see the front cover.

Problem: The console displays remain lit when you remove the key

• The console is in display demo mode. Hold the STOP button for a few seconds to turn it off. If displays remain lit, see Information Mode (page 19).

Problem: The displays of the console do not function properly

• Remove the key and UNPLUG THE POWER CORD. Place treadmill in storage position. Remove two #8 x 3/4" Screws (14). Lower the treadmill.
• Remove four #8 x 3/4" Screws (14) and remove the Motor Hood (61).
• Locate the Reed Switch (44) and Magnet (43) on the Pulley (42). Align the Magnet with the Reed Switch, maintaining a gap of about 1/8 in. (3 mm). Adjust the Reed Switch if necessary. Reattach the Motor Hood. Run the treadmill to check speed reading.

Diagram Description: Shows the motor hood removal and the location of the reed switch and magnet for speed calibration.

Problem: The incline of the treadmill does not change correctly

• Hold down STOP and SPEED increase, insert key, then release STOP and SPEED increase. Press STOP, then press INCLINE increase or decrease. This recalibrates the incline system. If it doesn't calibrate, repeat. Remove key when done.

Problem: The walking belt slows when walked on

• Ensure you are using a compatible surge suppressor (see page 14).
• If the walking belt is overtightened, performance may decrease. Remove key, unplug cord. Using the hex key, turn idler roller bolts counterclockwise 1/4 turn. The belt edge should lift 2-3 inches (5-7 cm) off the platform when properly tightened. Keep belt centered. Repeat until properly tightened.
• If the walking belt still slows, see the front cover.

Diagram Description: Shows the idler roller bolts and the recommended belt lift measurement.

Problem: The walking belt is off-center or slips when walked on

• Off-center: Remove key, unplug cord. If belt shifted left, turn left idler roller bolt clockwise 1/2 turn. If shifted right, turn counterclockwise 1/2 turn. Do not overtighten. Plug in, insert key, run treadmill, and repeat until centered.
• Slips: Remove key, unplug cord. Turn both idler roller bolts clockwise 1/4 turn. Belt edge should lift 2-3 inches (5-7 cm) when properly tightened. Keep belt centered. Plug in, insert key, and walk on treadmill. Repeat until properly tightened.

Diagram Description: Two diagrams illustrate adjusting the idler roller bolts for belt centering and tightening.

Exercise Guidelines

⚠️ WARNING: Before beginning this or any exercise program, consult your physician. This is especially important for persons over age 35 or persons with pre-existing health problems.

The pulse sensor is not a medical device. Factors like movement can affect accuracy. It's intended as an exercise aid for determining heart rate trends.

These guidelines help plan your exercise program. For detailed information, consult a reputable book or your physician. Proper nutrition and rest are essential.

Exercise Intensity

To burn fat or strengthen your cardiovascular system, proper intensity is key. Use your heart rate as a guide. The chart below shows recommended heart rates for fat burning and aerobic exercise.

To find your intensity level, locate your age at the bottom. The three numbers above your age define your "training zone": lowest for fat burning, middle for maximum fat burning, and highest for aerobic exercise.

Burning Fat

For effective fat burning, exercise at low intensity for a sustained period. After using carbohydrate calories, your body uses stored fat. Adjust intensity until your heart rate is near the lowest number in your training zone. For maximum fat burning, aim for the middle number.

Aerobic Exercise

To strengthen your cardiovascular system, perform aerobic exercise (activity requiring large amounts of oxygen for prolonged periods). Adjust intensity until your heart rate is near the highest number in your training zone.

Workout Guidelines

• Warming Up: Start with 5-10 minutes of stretching and light exercise to increase body temperature, heart rate, and circulation.
• Training Zone Exercise: Exercise for 20-30 minutes within your training zone (limit to 20 minutes in the first few weeks). Breathe regularly and deeply.
• Cooling Down: Finish with 5-10 minutes of stretching to increase flexibility and prevent post-exercise problems.

Exercise Frequency

Complete three workouts per week with at least one rest day between them to maintain or improve condition. After a few months, you may increase to five workouts per week. Make exercise a regular and enjoyable part of your life.
