Question: Do you have to have red safety button to work
Document: really like this treadmill because:I can adjust the speed, the height of the incline, and check my pulse as I go along. I also like that I can "do my own thing" or choose to do a set program.
i'd recommend buy it!its like going to the gym, the quality is so good it has different speeds inclines and workout modes and lets not forget the weights. also has a small KEY you use to start it so you don't have to worry about kids playing around it getting hurt if you remove the key. it is magnetic so I just stick it to the back of it so it cant be seen. I love it though worth the price
When you order the control board from the manufacturer it didn't come with the warranty like any other electronic parts. Make sure that you will do the routine maintenance lubrication of the treadmill belt.
Took us about 3 weeks to assemble. Still some screws wont fit. Its almost impossible to get someone to answer the phone at the customer service department, and once they do, its not help at all. We finally turned on the machine and it sounds like there's a body trapped inside the belt and then it stops. They want to charge us $150 for shipping to return it and about $250 to send someone to assemble it.
Took the one that was in good shape. Assembly took about 3 hours. Some part are not properly aligned, for example the display board wont get tightened and you will feel a loosen handle where the pulse gauge strip is located. The heart pulse gauge is way too off from curacy. The belt was off. Adjusted it but still going to one side. The display is ok. I have to keep a flash light to read the LCD display. The workout programs are buggy and erroneous.
This is the worst hunk of junk ever!!! Run as fast as you can from this machine and company. I bout a brand new treadmill from Walmart took about 2.5 hours to put together. Used it for 1 week and it dies. Spend 45 minutes two separate times with IT find that the light on motherboard isn't flashing as appears to be common. Was told a replacement control panel was being shipped will receive in 10 business days. So 10 business days later showing not shipped.
This is our first treadmill. I have had this treadmill for over a couple weeks now. I was able to assemble it all by myself and it probably took me longer than I expected. The complete unpacking and assembly time was about 2 hours since this machine is quite heavy and well built. All the parts were clearly marked and everything was delivered in perfect condition. Everyone in the family has been able to use this treadmill at home and enjoy it. We plan to use it primarily for fitness.
These would be a great treadmill but you need to buy ACL-SOL-50 high purity silicon oil from amazon to lubricate the treadmill belt every 50 miles of running through your treadmill in order not to break the control board. We used our 410 treadmill for almost 6 months without lubricating the treadmil belt until the treadmill was no longer functioning. I decided to order the parts which cost me $89.00. Now more than 1 year that we are using our treadmill without any single problem.
The pin that holds the treadmill up broke after less than 30 uses. I also noticed the belt is already showing signs of wear too. I will not be purchasing a Gold' Gym product in the future. I actually had purchased this product due to the all the good reviews I had read on different sites, but apparently these reviews were not from people who had actually used the treadmill for a period of time first.
It can go up to 10 miles per hour and I was very easily able to test the machine at 7 miles per hour. My 11 year old son enjoys running on this too. A good fit for the entire family.
