I searched "TX4.9" on those two sites and didn't see any keys... search "TX4.9" on fitnessrepairparts.com - they have a replacement safety key, see http://www.fitnessrepairparts.com/part_search/PartNumberSearch/TX4.9

Lost magnet treadmill


Hello. In the mean time you can use a fridge magnet to get you back on the machine. You might need a strong magnet, so if the first one doesn't work keep trying.
try googling the brand of machine you have to purchase parts or try eBay under treadmill safety keys.

Info from PDF files located on Sportcrafts website under manuals.
E3 - No speed sensor reading. Unit shuts down. This is the most difficult repair diagnose. The speed
sensor is connected to the frame of the treadmill near the drive pulley on the front roller. There is a
small magnet on the side of the pulley wheel. The sensor tip must be no more than 5mm from the
magnet. If for any reason the distance is greater than 5mm the treadmill will shutdown
Adjust or replace speed sensor.
Treadmill: Speed Sensor Replacement
1. Make sure your treadmill is unplugged before you begin.
2. Remove the motor cover located in the front of your treadmill, it is held on by a few screws.
3. Locate your speed sensor; it is the small T shaped part with a red and black wire coming from it.
4. Remove the 2 screws in the speed sensor and remove the old sensor.
5. Place the adjustment holder on the frame with the open holes facing the pulley wheel, the prongs facing
up and way from the pulley wheel. Insert the screws but don't tighten fully.
6. Now place the speed sensor over the prongs with the square part facing the pulley wheel and the red and
black wire to the far right.
7. Plug the treadmill back in and slide the speed sensor until it is 5mm from the magnet inside the pulley
wheel, you may have to do this several times until you can position it so it no longer shuts down. Use 2
nickels to figure out the spacing. The width of 2 nickels is 5mm.
8. Once you find the correct position tighten the screws all the way; being careful not to touch any of the other electronics
9. Place the motor cover back on and enjoy your machine.
Also:
Use an epoxy to glue it. It is a plastic that is difficult to adhere to.

Location of speed sensor on sportcraft tx 400 treadmills


It is a simple magnet and Hall effect transistor if you have 2 small wires. It usually attaches to the 1/8 inch mini plug. You can test it with an analog meter, the resistance will be stable at rest, and with treadmill in motion, the resistance will change as the magnet passes the hall effect switch. moving the track at slow speed manually will be enough to see the needle move. Speed is calculated off of the rate of those pulses.

We are getting a speed stall error on our True Fitness treadmill PS100. Is there anything we can do to fix it?


Yes you may be able to recalabrate the machine. A grade stall is when the machine does bot think the machine is at the right height. A bad lower board can also be the problem. True has those treadmills brought overseas. There not the american made quality of the units they useto make in MO.

It can be fixed. I know all the employees at True
