The PRO-FORM Whirlwind Dual Action Exercise Cycle, model number 831.280441, is a fitness machine designed for in-home use to provide cardiovascular exercise, build endurance, and tone the body. It features a dual-action design, allowing for both upper-body and lower-body workouts, or it can be converted to a stationary mode for pedaling only.
Function Description:
The exercise cycle operates by pedaling, which engages a precision belt system to create resistance. The dual-action handlebars move in conjunction with the pedals, providing a full-body workout. Users can choose to engage both the upper and lower body simultaneously in dual-action mode or disengage the handlebars for a stationary cycling experience. The console provides real-time feedback on workout metrics, helping users track their progress and maintain desired exercise intensity.
Important Technical Specifications:
- Model Number: 831.280441
- Weight Capacity: Designed for persons weighing up to 250 pounds.
- Power Source: The console requires four "D" batteries (alkaline batteries recommended).
- Display Modes: The console features six modes: Time (elapsed time), Distance (total distance pedaled, adjustable between miles and kilometers), Speed (pedaling speed), Calories (approximate calories burned), Fat Calories (approximate fat calories burned), and Pulse (heart rate via thumb pulse sensor).
- Adjustability: The seat height is adjustable to accommodate users of different heights, ensuring proper leg extension during pedaling. The handlebars can be switched between dual-action and stationary modes.
- Pulse Sensor: The device includes a thumb pulse sensor for heart rate monitoring, intended as an exercise aid for tracking heart rate trends. It is not a medical device.
Usage Features:
- Dual-Action Mode: In this mode, the link arms are connected to the pedals, allowing the handlebars to move with each pedal stroke, engaging both upper and lower body muscles. This provides a more comprehensive workout.
- Stationary Mode: To use the cycle for pedaling only, the link arms are disconnected from the pedals and clipped onto lock rods, allowing the handlebars to remain stationary.
- Console Operation: The console turns on automatically when pedaling begins or when the On/Reset button is pressed. It displays workout data such as time, distance, speed, calories, fat calories, and pulse. The display cycles through these modes automatically every seven seconds, or users can manually select a mode. To reset the display, the On/Reset button is pressed.
- Heart Rate Monitoring: The thumb pulse sensor, located on the console, provides heart rate readings. Users place their thumb on the sensor, and the heart rate appears on the display after a few seconds. It's important to press lightly to avoid restricting circulation.
- Seat Adjustment: The seat height can be adjusted by loosening the seat knob, pulling it out, and then raising or lowering the seat post until it locks into one of the adjustment holes. The seat knob must be tightened securely after adjustment.
- Bookrack: The console includes a bookrack for convenience during workouts.
- Water Bottle Holder: A water bottle holder is integrated into the design (water bottle not included).
Maintenance Features:
- Regular Inspection: All parts of the exercise cycle should be inspected and tightened regularly to ensure safe operation. Worn parts should be replaced immediately.
- Cleaning: The exercise cycle can be cleaned with a damp cloth and mild detergent. Abrasives, solvents, and liquids near the console should be avoided.
- Battery Replacement: If the console malfunctions, the "D" batteries should be replaced. Instructions for battery installation are provided in the assembly section.
- Belt Adjustment: The precision belt system requires proper adjustment. If the belt is too tight, it can damage bearings; if too loose, it can damage the fan or cause excessive noise/slipping. The manual provides steps for checking and adjusting belt tension by loosening guard fasteners and turning M6 Nuts. The ideal vertical movement in the center of the belt should be between 1/4 inch and 3/4 inch.
- Reed Switch Adjustment: If the console does not display correct feedback, the reed switch may need adjustment. This involves moving the Right Side Shield, locating the Reed Switch, aligning it with the magnet on the crank arm, and then sliding the switch slightly closer to or away from the magnet before re-tightening.
- Floor Protection: It is recommended to place a mat beneath the exercise cycle to protect the floor or carpet from moisture and dust.
Safety Precautions:
- Always read the manual before use.
- Ensure all users are informed of precautions.
- Use indoors on a level surface, away from moisture and dust.
- Wear athletic shoes; avoid loose clothing.
- Keep children under 12 and pets away from the cycle.
- Ensure link arms are fully seated on pedal bushings to prevent injury.
- Ensure the seat knob pin is inserted into an adjustment hole when adjusting seat height.
- Maintain a straight back during exercise.
- Stop immediately if pain or dizziness occurs.
- Consult a physician before starting any exercise program, especially for individuals over 35 or with pre-existing health problems.
