Frequently Asked Questions - XTR4 II Proflex

How do I assemble the Proflex XTR4 II elliptical bike?

Refer to the user manual for step-by-step instructions. Typically, attach the base, upright supports, console, pedals, and handles using the provided tools. Ensure all bolts are tightened securely.

What type of power does the console require?

The console operates on 2 AAA batteries (not included). Some models may also have an optional AC adapter. Always insert batteries with correct polarity.

How do I adjust the resistance level during workout?

Use the up/down buttons on the console to increase or decrease resistance. The magnetic system provides smooth transitions between levels.

What is the maximum user weight for this elliptical?

The maximum user weight is 120 kg (265 lbs). Exceeding this limit may damage the machine and void warranty.

How do I clean and maintain the elliptical bike?

Wipe the frame with a damp cloth after use. Regularly check all bolts for tightness. Apply silicone spray to the sliding rails occasionally. Keep the console dry.

Why is the console not turning on?

First, check the batteries. Replace them if necessary. Ensure the battery contacts are clean. If using an AC adapter, verify it is connected properly. Also, check the safety stop key (if present).

Can I use the elliptical without the console?

Yes, the elliptical can be used without the console, but you won't have access to display data or program features. The resistance will remain at a default level.

How do I transport or move the elliptical?

Use the transport wheels (if equipped) by tilting the machine forward. Alternatively, two people should lift carefully. Avoid dragging to prevent floor scratches.

What if I hear a squeaking noise during use?

Squeaking often indicates dry joints. Apply a small amount of lubricant (e.g., silicone spray) to pedal arms, handle pivot points, and rail surface. Tighten any loose bolts.

Where can I find replacement parts?

3. Attach the monitor to the head of main pipe. Screw two M5 screws back.
4. Insert the sensor plug to the monitor and install two AAA batteries.

ATTENTION: After assembly, please tighten all bolts of the above steps. Especially when tightening the bolts between the main pipe and frame, please ensure that 3 threads are visible outside the nut to avoid any wobbling.

Operation

Console and Functions

The equipment features a computerized display that provides you with workout information, such as duration, speed, distance travelled, pulse etc. The console activates as soon as a key is pressed or the pedals are moved. When the machine is not being used, the console switches off automatically after 4 minutes.

RESET

MODE

SET

Control Description
Display	Shows various information depending on current function. For example, current speed, used calories, current pulse etc.
	Note: When displaying pulse, you must have both hands on the metal sensors on the stationary handlebar. If no pulse is detected, "P" may be displayed and some functions are unavailable • To approximately convert calories to kilojoules, multiply the number of calories by 4.
MODE	Press to switch between available functions. The current function is indicated by having an arrow shown next to it:DIST - When in "setting" mode, program a target distance (range = 0 to 999.9 km).When exercising, shows the current distance travelled for the session.CAL - When in "setting" mode, program a target calorie amount (range = 10 to 9999 cal). When exercising, shows the current calories used for the session.ODO - When exercising, shows the current distance travelled for all sessions combined (returns to zero if the batteries are removed).PUL - When in "setting" mode, program a target heart rate (range = 80 to 180 bpm).When exercising, shows your current heart rate.TIME - When in "setting" mode, program a target session duration (range = 0 to 99 minutes and 59 seconds). When exercising, shows the current time elapsed for the session.SCAN - When exercising, automatically steps the display between each function every 4 seconds.
SET	Press to activate "setting" mode and to increase the current value when setting target values (for example, time, distance etc).
RESET	When in "setting" mode, press to return the current value to zero "0".

Setting a Pre-Set Session Time / Distance / Calorie / Pulse

When training to pre-set session values, the console beeps once you have achieved each target value. For example, setting a time of 5 minutes, distance of 3km, calories used of 50, and pulse of 110 will cause the console to beep if your pulse reaches 110, beep again if you use 50 calories, beep again if you travel 3km and beep again after 5 minutes. You can set targets for all values, or whichever ones you want.

1. Press MODE as required until the arrow is shown next to the required function (distance, calories, pulse or time).
2. Press SET to enter "setting" mode and apply a target value. Press again to increase the value or hold down to more quickly increase the target value.
3. Press MODE to step to the next function you want to set a target value for, then use SET to enter the value and so on. Repeat this process as required, then begin your workout.
   To cancel the target value and start again, press RESET (any other currently set values will remain unchanged).

Adjusting Resistance

The resistance of the crank to being rotated can be adjusted. Increased resistance requires more effort and, therefore, uses more energy. To adjust crank resistance, rotate the knob on the central brace - 1 = least resistance, 8 = greatest resistance.

Care, Maintenance and Troubleshooting

Some maintenance activities described may be beyond the scope of some users. For procedures that you are not comfortable with or have the tools or experience for, have the service centre or qualified technician.

Warm-Up and Cool-Down Routine

The warm-up routine is an important part of any workout. The purpose of warming up is to prepare your body for exercise and to minimize injuries. Warm up for two to five minutes before aerobic exercising. It should begin every session to prepare your body for more strenuous exercise by heating up and stretching your muscles, increasing your circulation and pulse rate, and delivering more oxygen to your muscles.

Always perform a cool-down routine after your workout, repeat these exercises to reduce soreness in tired muscles. The purpose of cooling down is to return the body to its resting state at the end of each exercise session. A proper cool-down slowly lowers your heart rate and allows blood to return to the heart.

A. Head Roll - Rotate your head to the right for one second, you should feel a stretching sensation up the left side of your neck. Then rotate your head back for one second, stretching your chin to the ceiling and letting your mouth open. Rotate your head to the left for one second, then drop your head to your chest for one second.
B. Shoulder Lift - Lift your right shoulder toward your ear for one second. Then lift your left shoulder up for one second as you lower your right shoulder.
C. Side Stretch - Open your arms to the side and lift them until they are over your head. Reach your right arm as far toward the ceiling as you can for one second. Repeat this action with your left arm.
D. Quadricep Stretch - With one hand against a wall for balance, reach behind you and pull your right foot up. Bring your heel as close to your buttocks as possible. Hold for 15 seconds and repeat with left foot.
E. Inner Thigh Stretch - Sit with the soles of your feet together and your knees pointing outward. Pull your feet as close to your groin as possible, then gently push your knees toward the floor. Hold for 15 seconds.
F. Toe Touch - Slowly bend forward from your waist, letting your back and shoulders relax as you stretch toward your toes. Reach as far as you can and hold for 15 seconds.
G. Hamstring Stretch - Extend your right leg. Rest the sole of your left foot against your right inner thigh. Stretch toward your toe as far as possible. Hold for 15 seconds. Relax and then repeat with left leg.
H. Calf/Achilles Stretch - Lean against a wall with your right leg in front of the left and your arms forward. Keep your left leg straight and the right foot on the floor; then bend the right leg and lean forward by moving your hips toward the wall. Hold, then repeat on the other side for 15 seconds.
