I get a Yellow arch on a Pronto M41 w/ SureStep for my best friend who has stage 4 cancer that has metastasized throughout her body. I am truing to get this working properly for her. I seem to charge fine, but is shows a hello wrench. Can you tell me what I should do?

It means there is a fault. You count the number of times it flashes and that tells you the error.

You may have misheard what was said. This may help, but as the previous answer states - you're in the wrong place:

"Non-cancerous tumours of the cervix

A non-cancerous, or benign, tumour of the cervix is a growth that does not spread (metastasize) to other parts of the body. Non-cancerous tumours are not usually life-threatening."

The AMBER service indicator will light when an error or fault occurs. This is a yellow wrench shape. Refer to Diagnostic Codes on page 33 for a listing of the flash codes and what they indicate:

Hello,

The Pronto M41 does not have a speed limiter per say. If the chair used to go faster than it does now then you may have some kind of problem with the chair. If the chair has always driven' slow, that is slower than the maximum 3.5 to 4 MPH then a Invacare Remote programmer is needed to program the chair to go it's full speed.
Seek a Invacare dealer and ask them if they can check the programming.

Since time was important this may be too late.

1. You can download manuals for pretty much anything by asking Google for something like 'Pronto M41 manual'. Manuals help a lot.

2. Googling 'wheechair repair [your town]' will point you to people who can service the chair. You can also contact a local agency for people with disabilities for ideas.

The yellow wrench is a diagnostic tool. How many times does it blink between pauses. Example might be 3 blinks then pause then 3 blinks then pause, over and over. Hoe many does your chair blink?

Have you replaced the batteries ever? I was told by my local Invacare vendor that the batteries are only good for 12-18 months. My mom's Pronto M41 was having battery problems and replacing both batteries solved the problem in her chair bought in 2007. Now she is looking to buy a slightly used chair (4 mos old) from the family of a deceased friend and there seem to be issues with the batteries in this almost-new chair.
