Frame construction

The Sunny Health & Fitness SF-T7946 is a light-capacity treadmill but still has a fairly decent construction. To begin with, its deck is designed to support users up to 220 lbs (100 kg). Its frame is steel-made, with the side rail covers and the motor cover made of durable ABS material. All the frame steel parts are coated with a corrosion-resistant paint finish. The color used is gray, while the ABS covers are white. These are the only colors available for this model.

Like most other light-capacity walking treadmills, the Sunny SF-T7946 model doesn’t have a super-large footprint. However, it does take approx. 59″L x 32″W (150 x 81 cm) of floor space. Plus, it is recommended to leave at least three feet of clearance at the rear of the deck, and at least two feet of clearance on each side of it for ease of access and safe usage.

One of the best features of this Sunny treadmill is its slim-folding design. The two upright masts of the machine with the console can fold all the way down over the deck. The two side handlebars are also foldable. The folded unit can be stored vertically; its front base frame unfolds to serve as an additional stabilizer when the treadmill is stored upright. In folded position and stored upright, the machine’s dimensions are 13″D x 38.1″W x 59″H (33 x 81 x 150 cm).

The fully assembled treadmill isn’t extremely heavy. It weighs approx. 88 lbs (40 kg). The boxed unit is heavier (approx. 105 lbs), so its transport may require two persons. But once the unit is unboxed and ready to use, it can be moved by only one person. Its front base features a set of small wheels for this purpose. Also, the machine has adjustable and rubberized stabilizers under the front and rear sections of the deck.

Deck construction

First of all, the Sunny Health & Fitness SF-T7946 offers a walking surface of 48″L x 17″W (122 x 43 cm). Now, considering that it’s not a machine made for high-speed running (its maximum speed is 7.5 MPH), users up to 6’3″ (190 cm) should be able to use it with no problem for walking and light jogging.

The tread belt is multi-layered, featuring a rubberized layer at the top which delivers an excellent grip. The deck integrates six concealed cushioning elements, three on each side. Two pairs of cushions are placed at the rear of the deck for a bit of extra bounce, while the front section of the deck only has one pair of cushions for extra firmness.

This Sunny Health & Fitness treadmill doesn’t have an incline system. However, the deck doesn’t stand completely flat on the floor. It is slightly higher at the front (so, it has a default incline of approx. 2°).

Since the treadmill has a slim design, the walking platform stands only approx. 5″ (13 cm) above floor level. So, it should be used in a room with a ceiling that is at least 10″ (25.4 cm) higher than your own height.

Drive motor

The Sunny SF-T7946 treadmill is equipped with a 1.5 HP (peak power) motor. It offers a speed range between 0.5 MPH and 7.5 MPH and is designed to provide a continuous belt motion during prolonged workouts even if the user is close to the maximum 220 lbs (100 kg) capacity.

The speed adjustment increments are approx. 0.1 MPH. Therefore, the transition from a level to another is done smoothly without jerks or sudden changes, so you can easily adapt your pace. The console offers controls for gradual speed adjustment and quick speed adjustment for 3 MPH, and 6 MPH.

As we’ve mentioned above, this Sunny treadmill offers several preset workout programs. When a program is in use, the machine adjusts the speed automatically. Needless to say, during each program, the automatic speed adjustment is also done smoothly, allowing you to adapt your pace.

The motor itself is fairly quiet. It doesn’t generate a lot of noise when in use, but when running at a higher speed, the thumping of your cadence will be heard. Also, since it isn’t an extremely powerful motor, you won’t have to worry about a high electricity bill even if you use the machine daily.

Console

The Sunny Health & Fitness SF-T7946 treadmill is equipped with a LED console, similar to the Sunny SF-T7909 model. Its display is divided into four sub-sections. From left to right, the four LED windows indicate time, speed, distance, and calories burned. Speed is shown in MPH while distance is shown in miles.

The console does not have a pulse reading function and it is not compatible with any wireless HR chest strap. Therefore, if you need to monitor your pulse during your workouts, you will have to use a separate device.

The console makes available 15 programs. Each program has 20 segments and a default time of 30 minutes. So, the duration of each segment is by default 30/20. However, the duration of each program can be adjusted before launch.

The console also offers countdown settings for time, distance, and calories. If a countdown value is selected for any of them, the console will count down from the selected value until it reaches zero, always showing the remaining value of the selected goal.

The console is very easy to use. It has buttons for gradual speed adjustment, quick selection speed adjustment for 3 and 6 MPH, Start/Stop buttons, and the Programs button. It has a sleep mode function as well; it enters sleep mode after 10 minutes of inactivity on the machine.

One last notable console feature is the tablet holder. This accessory is attached to the top center of the unit and expands in order to accommodate any type of tablet. However, it’s important to mention that the console doesn’t have any ports (USB or AUX) for connecting your phone or tablet to it.

Assembly and Maintenance

The treadmill comes fully assembled and folded. All you need to do is unfold the two upright bars with the console, and lock them in an upright position with the provided knobs. The manual provides all the necessary instructions for it, although the task is pretty straightforward.

For maintenance, the lubrication of the deck is necessary. The manual also provides guidelines for it. A bottle of lubricant is included. Other than this, the belt should be kept clean to prevent any debris or textile fibers to be caught into the motor or the rollers.
