If you can alter the speed, there will be a dial on the armrests to turn it down, i presume you have 4mph and 8mph,the dial will adjust the speed , so that it takes longer to reach 8mph.

I have a pronto M61. Forward speed is very slow even when adjusted to higher speeds. Turning speed increases normally. Is there a problem in the joystick?

Has this chair got power raiser for seat? if so check it is fully down or check down micro switch. These will not go fast with the seat raised. A safety option built in.

How do I speed up a Merit Vision Sport?

As the user of the chair, you will not have the ability to speed up your chair unless you have the specific programmer to raise the speed. Typically mobility specialist will turn your speeds down until you get used to the chair and then come back out when you are capable of driving chair at faster speeds. You will have to call the dealer who slowed it down or, another DME company in your area to have the chair speed adjusted.

Why is my merits DL 5.2i stuck in low speed ?

You may have a thermal rollback issue. Try charging the chair overnight and leave the controller on while charging. This will give the control module/joystick time to reset themselves. Thermal rollback happens when a certain temperature in the motors is reached. The system shuts itself down to protect from damage.

Pride Motor Chair 2008 Vr2 Controller Speed adjustment lights go to fast setting but chair barely crawls along!

Great question! The slow flash is indicative of a speed reduced mode on models designed for a seat lift option. If the controller detects that the seat is elevated then the speed is reduced - regardless of what you try to do at the joystick.
First - try lowering the seat to its lowest position.
If this doesnt work then look for a bad or disconnected sensor switch on the seat post. There are two leads at a 2-pin plug that are not making a connection when the seat is lowered - causing the controller to sense the chair is not safe to drive fast.

How do we lock out the fast speed on grandpa's chair so he doesn't hurt anyone?

Ann You will have to contact the provider of Gramp's chair to ask if they have a programmer for Invacare chairs. Then they will have to program the chair for a lower speed. Of course you can turn the speed down on the joystick but Grandpa is probably the one that will put it back to fast cause its going too slow. try also contacting Roadrunner Mobility@ 1-800-467-2668 and ask if they have a tech in your area that has a progeammer to slow his chair down. Hope this helps

To slow, i need it to go faster

Are your batteries fully charged? Are the batteries 2 years old or older? Even with a full charge older batteries will not generate amperage to make the chair go as fast as when new. Also the motors tend to slow down with age due to brushes wearing down. Now, if the batteries are new and the motors are not that old then you need to find a wheelchair provider that has a PP1 programmer and have then check the settings for forward speed etc. If the speed is not set to 100 then they can increase the forward speed to 100%. Hope this helps you

My Ryobi power unit runs very slow...All the attachments run there some way to get the gas engine to speed up?

There should be a couple of screws on the side that have icons or letters, one is for slow or low speed jet and the other is for fast or high speed jet, take a little screw driver and open up the high speed jet with it running, till it gets going, if it slows down, you are going the wrong way. Sometimes it will say something like 1 1/4, that means that the starting point is 1 1/4 turns out from closed. Try it, hope this helps.

Reverse speed too high

No, the controller must be reprogrammed and you will need an Invacare service tech to bring his hand-held programmer over to make the corrections to the chair.
