How does the Smith bar work, and how do I change the weight? The SF6 has a patented, quick-change selectorized Smith bar. Set your weight with the selector pin, and make sure it&#x2019;s fully inserted before you train. Routine weight changes are made from the front of the machine, so you don&#x2019;t need to reach around the sides or back.How much resistance does the SF6 provide, and how many pulley positions does it have? Two 165 lb weight stacks give you 330 lbs total. A built-in weight multiplier raises the maximum resistance to 350 lbs. The cable system uses a 2:1 resistance ratio, with six pulleys and 30 vertical positions.What is the pull-up bar&#x2019;s weight limit, and how is its height set? The multi-grip pull-up bar supports up to 350 lbs. It has three height positions, which are set during assembly by choosing a hole in the lat beam tube.How big is the SF6, and how much space do I need? The SF6 measures 59.1 inches long, 54.8 inches wide, and 88.7 inches high, and weighs 666.7 pounds. Plan for a workout area of about 9 feet by 9 feet, with about 10 feet of ceiling height. Anyone else in the room should stay at least 5 feet (1.5 meters) away from the equipment while you train.What accessories are included? The SF6 includes two rubber D-handles, a triceps rope, an EZ curl bar, an ankle strap, a multi-purpose belt, and an accessory holder.Does the SF6 include Centr Coach? Yes, the SF6 includes 30 days of Centr Coach. A one-year Centr Coach subscription is also available for $159.99. If you have trouble activating your included trial, contact our support team.How long does assembly take? Assembly involves 17 steps and several hardware packs, so set aside plenty of time and keep the user manual handy. Follow the steps in order, and tighten hardware only when the manual says to. Check that the Smith bar rotates freely before you finish.How do I safely secure the Smith bar overhead? Before you leave the machine, check that both red hooks are fully engaged on the frame and that the locking pin is in the locked position. The Smith bar should be hooked and locked with the swivel safety latch. Only trained users should lift and secure the bar overhead.Who can use the SF6? Only one person should use the SF6 at a time, and no one else should be in the exercise area while you train. Keep children and pets away at all times. Children shouldn&#x2019;t use the machine, and teenagers ages 13 to 17 should only use it with adult supervision. People with disabilities should only use it with a qualified person or physician in attendance. Consult a physician before starting any exercise program, especially if you&#x2019;re over 35 or have a pre-existing health condition.What safety precautions should I follow? Inspect the machine before each use, including the cables, belts, and connections. Don&#x2019;t use it if any part is worn, damaged, or not working. Warm up before you train, and wear running or training shoes and clothing that won&#x2019;t catch on moving parts. Don&#x2019;t use the machine for support during stretching, and don&#x2019;t attach straps, ropes, or other equipment unless the manufacturer allows it. Never try to free a jammed part yourself. If you feel dizzy, nauseous, or faint, or you have chest pain, stop right away and consult a physician.Can I use the SF6 outdoors or in a commercial gym? The SF6 is designed for home use only. Don&#x2019;t use or store it outdoors or near water. After each use, secure the machine so unauthorized people can&#x2019;t access it.How do I maintain the SF6? Inspect the cables regularly for splitting, cracking, fraying, bulging, or flat spots, paying close attention to the ends. Replace any cable at the first sign of damage or wear. Cables stretch over time, so check the slack and adjust tension as needed. Also check snap links, swivels, handles, and the weight stack pin for wear, and make sure all hardware stays tight. Wipe the guide rods with a dry cloth and apply a thin coat of Teflon-based lubricant every so often. Follow the maintenance schedule on the label on your machine.What should I do if the Smith bar doesn&#x2019;t move freely? The manual advises adjusting the bottom of the front uprights on the base, then retightening the bolts from assembly step 2. Make sure the Smith bar stays level as you lower it onto the guide shafts, since uneven installation can cause binding. If the problem continues, or if any cable or component is worn or damaged, stop using the machine and contact our support team.What warranty comes with the SF6? You can register your SF6 and view the full warranty details at centr.com/pages/warranty-registration. To file a claim, have your serial number, proof of purchase, and receipt ready. You&#x2019;ll find the serial number on the machine&#x2019;s label, and the front page of the manual has space to record it.Are replacement parts available? Yes. Contact our support team with your serial number to order the parts you need. Use only genuine Centr parts. Using other parts can void your warranty and could cause injury.Still need help?
