SOURCE: How do I charge My Pronto M51 motorized wheelchair?

Margie,   Yes you may charge it overnight. If you use it everyday,charge it every night. Once the charger senses 24 volts it stops sending a charge,so they cannot be overcharged.  I suggest when you go to bed put on the charger and unplug it when you get up in the morning.

SOURCE: won't move pronto m51

Three lights flashing on your chair indicate a left motor fault. Make sure that all of the connections inside the shroud are tight by physically testing them. If all of the connections are good, and the fuses are good, then it's time for a trip to an authorized repair facility. Here is a link to the M51 owners manual if you haven't one. Page 24 has the fault code guide.

The controller monitors all of the functions on the chair, brakes, motors, joystick, charger etc. The three flash fault indicates an "open" circuit. Open, like a switch or blown fuse is open, or a wire is cut or burned in half, or a connector is unconnected, or partially connected. The latter is what you are hoping for. Wires burned in half is the usual cause for a motor fault, and with powerchairs, is usually the result of the chair getting stuck in or against something it can't get out of and the operator over-amping the motors. Motors do, just go bad sometimes, for no reason. Very rarerly, however.

You can also check the brushes on the motor too. There's two quarter-sized black plastic screw-plugs on the ends of the motor opposite each other. Unscrew them and examine the brushes. The springy coils should be springy. Overheating can cause them to be brittle, or even burned in two. Check the lench of the brush, the dark rectangular cube at the end of the springs. It should be curved and polished at the end, and a little over a half-inch long. If it is near a 1/4 inch, it needs replaced, or if there is any evidence of overheating, replace. Good luck.

How to remove drive wheel

The drive wheel has a locking tab washer under the bolt which holds the wheel assembly on the end of the drive shaft. Step one is to bend the tab (or tabs) away from the side of the bolt. Put a socket on the bolt to remove it. Make note of the washer and lock tab orientation because there is another tab on the inside which locks into the motor shaft keyway. Spray lube into the shaft and keyway to free up the wheel and remove. A wheel puller is sometimes helpful here. When replacing the parts use Loctite on the bolt and tighten. The final step is to bend a lock tab up against the bolt head to keep it from backing out. The hard part of this whole process is removing the wheel assembly from the motor shaft. It may have seized on to the shaft. Place anti-seize or grease on the shaft after cleaning and before reassembly.

What size/dimension are the center drive wheel bolts?

Those are metric(M8 x 1.25 x 20mm). The caster wheels are 7/16-20 x 3-1/4". Make sure you also install a lock washer and a flat washer when you reassemble and always check the tightness every now and then as they can loosen up if you are doing a lot of driving around.

How to change battery on pronto m51

The Pronto M51 has two batteries in the base. The seat has to be removed to change the batteries. The M51 has had several methods of removing the seat from the base. The oldest models have a long bolt that holds the seat to a center post that sticks up from the base between the batteries. The next version has a spring loaded red handle just under the right side of the seat. If you have one of these designs you must lift the seat straight up off the center post. If not lifting straight up the seat will not come off.

The last style has the seat frame bolted to the base frame in 4 positions. Only one bolt at each corner post needs to be removed.

The wheels on my friends electrically powered Pronto 51chair are spinning on the carpet(which is not particularily worn). Are there any tricks short of new wheels that help remedy the situation?

Jet turn the speed down on the chair to try a slower speed it might help with the spinning and make sure the casters are turning freely and not creating a bind or excessive drag on the drive wheels. Good Luck Hope this helps you
