Question about Invacare Pronto M51 Power Wheelchair

1 Answer

Pronto M51 feels forced when driving it.

My pronto m51 has begun to feel as if it is forcing itself when driving it. My husband began to feel this when moving it manually a couple of months ago. I began to feel it about 1 month ago. Also, it suddenly makes a squealing sound when driving it for a several minutes. It is 3.5 years old. I would also like to know if this is something that can leave me stranded when I am out. Thank you.

The squealing noise is probably a bearing either in one of the four smaller tires called casters. The problem will not likely cause a break down right away but should be checked by someone mechanically inclined or trained in power wheelchairs. I don't know what you mean by the chair being "forced". Need more info.
May have something to do with batteries.

If the chair is driving slower and batteries are new their is a recall for that joystick from Invacare. Invacare is replacing joysticks for free.

Testimonial: "Thank you very much for responding. By forced I mean it seems like it is pulling back when I am driving. Hopefully that makes sense. I had problems with the joystick soon after getting my chair and had it replaced. This does not seem like the problem I had then, but perhaps it's just not as severe as then. I also noticed a noise recently that sounds as if someone kicked the battery cover. It also felt as if I'd run over a small object. I am relieved to know it's possibly not a big repair. I've been trying to get a mechanic to come look at it, but have not had any luck. Hopefully I will find someone soon. I feel unsafe leaving the house. Thanks again!"

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.
http://www.invacare.com/doc_files/1125085.pdf

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.

The chair has two levers, one for each motor, that disengage it for freewheeling, or pushing the chair without power. These take it out of gear. Place the levers in the locked, gear-engaged position and it should go for you. Here's a link for the manual for your chair, and it will show you where the location is to place it in gear.http://www.invacare.com/doc_files/1125085J.pdf

SOURCE: What is the proper way to charge the Pronto M51

Eduardo After using your chair and the battery level lights are down with yellow or red lights showing just plug the chair into the wall socket and let er rip. Now really after using your chair during the day and you are ready for bed just plug in the charger and let it charge over night. In the morning unplug the charger and you should be set for the day. If you don't use the chair everyday always put it up with a full charge and about once a week plug it in and let it charge overnight. Never leave the chair plugged in all the time and never leave it for more that 24 hours. The charger has two lights on it one red and one yellow or green that are hard to see because they are under the rear cover. When the chair is fully charged the yellow light turns green and you can unplug the charger and you should have a full charge. Hope this helps you

The circuit breaker is located on the base of the chair. It is a small button about half the size of a dime, and it often has a flexible cover over it. If it is tripped, you will feel a click when you push it as it resets.

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.
