Frame and deck

The Nautilus T618 treadmill is built on an extremely sturdy steel frame, coated with a corrosion resistant and scratch resistant, industrial-grade finish. The colors used for the frame paint are light gray and black, these being the only colors available for now. The nautilus t618 performancemachine’s construction also integrates several hard PVC parts, such as the covers of the rear feet, rear roller covers, motor cover, side rails and the accessory tray. These, however, do not have any impact on the machine’s overall sturdiness.

Like most treadmills, the Nautilus Performance T618 is a fairly large fitness machine. It takes 72.4″L x 35.2W (184 x 89 cm) of floor space and it requires at least two feet of clearance on each side, and at least three feet of clearance at the rear for safe operation. However, the deck integrates a fold-up mechanism. It’s equipped with a hydraulic lift which locks it in upright position and provides soft-drop unfolding. With the deck folded up the machine’s length is reduced by half.

This Nautilus treadmill is considerably heavy. It weighs approx. 253.5 lbs (115 kg) when fully assembled; therefore, its transport and assembly require at least two people. But on the other hand, all this weight plays an important role in its overall stability. You can be sure that the machine won’t wobble, shake or change its position even during the most demanding workouts. On top of that, its front metallic base is equipped with four adjustable, rubberized stabilizers, which give you the possibility to perfectly level it on any type of flooring or pavement.

Once the treadmill is assembled, its relocation isn’t too difficult, as its front metallic base also integrates a set of wheels. By leaning it onto its wheels, you will basically have to handle less than half of its weight when relocating it.

The treadmill’s running platform is equipped with a more durable belt than the T616 model. It’s a 3-ply, 2.5mm, light commercial Trye belt, while the older model only has a 2-ply belt. The belt rolls over large, 2.75 crowned rollers, designed to prolong its lifespan and to maximize stability. They integrate heavy-duty, sealed ball bearings for smooth operation.

The running surface is the same as for the T616, though. It’s 60″L x 20″W (152.4L x 50.8W cm) and can accommodate comfortably users up to 6’6″ (198 cm). However, it’s designed to support heavier users, up to 350 lbs (159 kg).

nautilus t618 - reboundTM deck cushioning

The machine’s deck integrates the ReboundTM cushioning system, featuring two sets of shock absorbers at the front, and three close to the rear. The front cushioners soften the landing of each foot reducing impact, while the rear ones propel the kick-off providing an energy boost to the stride. Due to these features, the workout-related pain is considerably diminished, which allows you to undertake longer and more consistent runs.

One last aspect to mention here regards the accessory tray. This Nautilus treadmill features a PVC crossbar tray which attaches by the two console masts of the machine. Along with the accessory compartments, this tray also features a towel bar.

Incline and step-up height

The Nautilus T618 treadmill is equipped with an automatic incline system, offering a ramp between 0% and 15%, perfect for high-intensity interval workouts. It consists of a small nautilus t618 - automatic deck inclinemotor and a lift, situated at the front of the deck. Evidently, since the incline system is motorized, the ramp of the deck can only be adjusted if the machine is connected to a power circuit. Also, you can only adjust the incline from the control unit, or from the keys integrated into the left handlebar.

The incline adjusts in increments of 1%. However, the console features keys for the quick selection of the 0%, 2%, 5%, 8%, 10%, 13% and 15% positions.

The deck’s running surface is situated at approx. 9″ (23 cm) above floor level. In other words, the machine’s step-up height is 9″. The space remaining between the deck and the floor is approx. 4.5″ (11.4 cm). These being said, in order to avoid any ceiling height issues, make sure that the ceiling in the room where you will be using the machine is at least 15″ (38 cm) taller than your own height.

Motor

This Nautilus Performance treadmill is equipped with a 3.5 CHP, heavy-duty motor. It’s a continuous duty motor, made to withstands prolonged workouts at maximum speed without overheating or losing performance, even if the user is close to the maximum weight capacity. It is also equipped with a small flywheel which adds stability to the belt motion.

The motor offers a speed range between 0.5 MPH and 12 MPH. Needless to say, speed is adjusted exclusively from the console. Just as for incline, you’ll find gradual and quick adjustment keys for speed. Speed can be adjusted in increments of 0.1 MPH. This gives you the possibility to find the perfectly suited pace for you, for each workout.

The machine comes with a standard U.S. 3-prong plug, not an adapter. It requires a 120V 15A power circuit. It’s recommended that the machine is connected to a power circuit solely, without other devices connected to the same circuit, to avoid surges. Also, it’s not a bad idea to use a surge suppressor, to prevent any damage to the motors or console, in case a surge happens.

Control unit

The Nautilus T618 treadmill is equipped with a multi-function console. It has two LCDs with blue backlight, 3.75″ (top) and respectively 5.5″ (bottom) in diagonal.

The top, smaller display indicates the goal of the workout, your fitness score and your placement in relation to the pacer. The bottom, larger display covers a lot more info, including the program profiles, time, distance, laps, heart rate, calories, speed, incline, pace. Distance can be tracked in miles and kilometers, while speed can be calculated in MPH or km/h. For the Lap Count function the distance is calculated in laps of 0.25 miles (0.4 km), a function great to have if you want to undertake a workout designed for professional runners.

The console is telemetric; it can track your pulse via the included wireless HR chest strap. However, you can also monitor your pulse by holding on to the sensors integrated into the front handlebars of the machine.

There are several sets of workout programs built-in the console unit.

  • Quick Goal program which allows you to set up an exercise goal for distance, time and calories, and work towards that goal.
  • Heart Health program which offers four preset target heart rates, for 55%, 65%, 75% and 85%.
  • Weight Control program which has five preset workouts: Fat Burn 1, Fat Burn 2, Speed Burn, Incline Burn and Dual Burn.

  • Train program with six more programs including Boot Camp, Endurance, Performance, 1 Mile Pacer, 5K Pacer and 10K Pacer.
  • Custom program – offering four customizable programs, for heart rate, incline, speed.

The console unit lets you store and use 4 User Profiles, each profile recording the workout results in order to be reviewed later. Each user profile stores data regarding age, weight, height, gender, name and preferred workout values. It’s a great function to have if multiple persons use the machine. Also, since you can input data regarding age, gender, weight and height, the unit can determine your calorie burning percentage much accurately.

Along with the onboard programs, this treadmill also offers the possibility to connect online for in order to track your progress. The console is Bluetooth-enabled, allowing you to sync it with your smartphone, laptop or tablet, in order to use the “Nautilus Trainer” fitness app, or directly transfer your workout data into your Nautilus Connect or MyFitnessPal account.

For maintenance, you should keep the belt and deck clean, free of any objects that may be caught by the belt and dragged into the rollers, or damage the motor.
