SF-T7604 Frame construction

The Sunny SF-T7604 treadmill features a steel frame combining ovalized and rectangular bars in its construction. All the steel tubes come coated with a rust-resistant paint finish; the color used is dark gray, this being the only color available for this model.

Of course, the machine also integrates several durable thermoplastic parts. For example, the side rail covers, the motor cover, the console dashboard, and several other small covers are plastic-made.

Compared to other treadmills, the Sunny SF-T7604 is a bit smaller. However, it still is approx. 66.5″ (169 cm) long, and 29.5″ (75 cm) wide. Plus, it is advisable to leave some clearance around it for safe usage, at least two feet on each side and at least three feet at the rear.

The unit’s frame has a folding mechanism. The deck can fold up for better storage possibilities; this also makes it much easier to clean under the deck. The folding mechanism uses a hydraulic cylinder that lowers the deck slowly when unfolded to prevent damage to it or the floor.

Also, with the deck folded, the machine’s length is reduced to 41.75″ (106 cm) while its height becomes approx—58″ (147 cm).

Although it’s a treadmill made for home use, the Sunny SF-T7604 is pretty heavy. With all the parts assembled, it weighs approx 130 lbs (59 kg). All this weight adds to its overall stability.

Plus, its front base rests on six flat rubber pads, which improve its stability. The front base frame also has a set of wheels that facilitate the machine’s relocation when folded.

Deck construction and incline

The Sunny Health & Fitness SF-T7604 features a pretty sturdy deck. It has a maximum user weight capacity of 265 lbs (120 kg), which is not bad for a home-use machine. It offers a running platform of 51″L x 18″W (130 x 46 cm) using a multi-layer belt with a rubberized top for an improved grip.

Although the machine’s running platform isn’t as large as for a commercial treadmill, it’s still long and wide enough to provide a complete range of motion for users up to 6’0″ (183 cm).

The exact dimensions of the integrated rollers are not specified. However, they have indeed crowned design for improved traction. They also integrate high-grade ball bearings for a smooth motion.

Although the Sunny SF-T7604 is a treadmill designed for home use, its deck integrates quite a few cushioning elements. Each side of the deck incorporates two large cushions for reduced vibration and three smaller cushions for reduced impact.

The deck itself also has a bit of flex. These being said, walking or running on this treadmill generates considerably less impact on your joints and back.

The treadmill features a manual incline system. It consists of two folding rear stabilizers, each one featuring three adjustment positions. The deck’s incline is adjustable by locking each one of the two rear stabilizers in the desired position with the provided pins.

The available incline levels are around 0°, 1°, and 2°. Since the incline system is manual, you cannot adjust it while walking or running on the treadmill. To change the incline, you have to stop the belt and step off the deck.

With the incline set to 0°, the step-up height of the deck is approx 8″. Of course, with the highest pitch, the rear of the deck is a bit lower. Nonetheless, it is advisable to use the machine in a room with a ceiling height of at least 10″ (25 cm) higher than the tallest user’s size.

SF-T7604 Drive motor

The Sunny Health & Fitness SF-T7604 comes equipped with a 2.5 HP motor. It’s not a super duty motor like the ones on the commercial-grade machines but does offer enough continuous power to keep you running for two hours. The manual recommends, though, turning off the machine for at least ten minutes after every two hours of use.

The unit’s motor offers a speed range between 0.6 MPH and 11 MPH. The speed adjustment increments are 0.1 MPH, so the transition from a level to another is done smoothly, allowing you to adjust your pace.

The treadmill’s console features controls for gradual speed adjustment and quick speed adjustment. The incremental adjustment controls have a double function. If pressed once, they adjust the speed by 0.1 MPH, but you can also press and hold for continuous speed adjustment.

The quick speed selection controls offer the possibility to select 1 MPH, 2 MPH, 3.5 MPH, 4 MPH, 4.5 MPH, 5 MPH, 6 MPH, 7 MPH, 8 MPH, 8.5 MPH, 9 MPH, 9.5 MPH, 10 MPH, and 11 MPH. Also, the console has several workout programs that adjust the speed automatically.

Finally, since the machine doesn’t have a super powerful motor, its power consumption is minimal. So, even if you will be using it daily, it shouldn’t add more than a few dollars to the electricity bill.

Also, the motor itself doesn’t generate a lot of noise when in use, but depending on how fast you go, your cadence may create more or less noise.


The Sunny Health & Fitness SF-T7604 doesn’t have a super console but does cover all the essential treadmill functions. To start, it features an LCD (with LED backlight) for improved readability.

The display is divided into several sub-sections to show multiple readings at once, tracking time, distance, speed, calories, and pulse. The speed is shown in MPH, while the distance displays in miles. There is no possibility to set these values to metric units.

Also, the console is not telemetric. In other words, if you want to monitor your pulse, you will have to hold on to the sensors integrated into the side grips of the machine; the console cannot communicate with a Polar or ANT+ pulse strap.

The console unit makes available 15 pre-set programs, three user profiles, a Body Fat function, and of course, the Manual mode.

Each one of the 15 (P1-P15) pre-set programs offer different types of workouts. Some are best to use if you want to lose weight; others are interval-based, while others gradually increase the speed, then lower it. Each of the pre-set programs has its grid figure shown on the console (right and left from the display).

The user profile programs (U1-U3) offer to create and save three custom programs with the desired duration and speed settings. Therefore, if up to three persons use the machine, each one can make and keep their program.

The Manual Mode gives you the possibility to run or walk freely, adjusting the speed manually. For this workout mode, you can also set up targets for time, distance, and calories. And finally, the Body Fat function can calculate your body fat percentage if you input your age, weight, height, and gender.

Of course, the console dashboard features two bottle holder compartments and two other small trays that you can use to store various small accessories. However, it does not have a tablet holder. It also does not have a sound system feature, a cooling fan, a USB charging port, or online connectivity.

SF-T7604 Assembly and Maintenance

The Sunny SF-T7604 treadmill comes pre-assembled and folded. You only have to unpack it, remove the straps that hold it in place, unfold the two upright bars with the console, secure them in place, add the side frame covers, and plug it in.

This shouldn’t take more than 30 minutes. All the necessary tools come included, and the manual provides pretty clear assembly instructions.

For maintenance, the machine’s belt needs cleaning to prevent debris from being caught in the motor or the rollers. The deck requires periodic lubrication every two months if it uses more than 5 hours per week or six months if for less than 3 hours per week. A bottle of lubricant comes included. Other than this, it is also advisable to periodically inspect the machine to make sure that all the parts function correctly and there are no loose bolts or parts.
