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?

M61 flash codes, nothing for M6

Hi Christi:
This is a "standard approach" that i've used for various small engines for a long time. It may not be factory specs, but it's worked for me.
- First, gently turn both screws in (clockwise) until they just touch the seat. BE GENTLE as you don't want to damage the needle or seat.
- Second, back out both screws 2 turns. This is a "guess" start point.
- Third, start using normal procedure.
- Once the choke can be opened, with the saw at an idle, adjust the slow speed screw until the saw runs at its slowest smooth idle.
- Finally, increase the engine speed and adjust the high speed screw.
Try turning it clockwise.
- If RPM increases, continue until it starts to decrease, then back off 1/4 to 1/2 turn.
- If RPM dropped or engine stalled, back off 1/2 turn and try again.
Hope this helps.

You will need to contact a service tech in your area to do this. They should have a special programmer box that can adjust the settings on the chair to improve the chairs performance.

Test the battery voltage at the joystick where a programmer or charger would plug in. There are 3 holes, the top or number one hole is the positive hole for a voltage meter to plug into and the bottom or number two hole is the negative hole for the volt meter. Plug in the meter and see what the voltage is when sitting still and keep the meter in and see what the voltage does while you are driving the chair. The voltage should not drop more than 1 or 2 volts from that which you had when the chair was not moving. If the voltage drops more than that then there is a problem with charging or the new batteries. If the voltage remains good then the joystick or speed knob control could be the problem.

The chair may be in what they call SLOW MODE or the batteries are weak. If you have powered seating on the chair the seat has sensors that make the chair drive slow or not drive at all when the seat is tilted or reclined or raised. A sensor can go bad or get out of position. The joystick could have different programming for different drive modes. Try changing drive modes.

Low oil pressure at idle can be caused by an engine with worn rod or main bearings due to (usually) high mileage . This however does not mean the engine is still not serviceable as long as the oil pressure is low only at idle. The pressure should at minimum get into the normal range at anything above idle speed.Not much oil pressure is really necessary at LOW speed. At low speed, as long as there is oil getting to the bearings, even at low pressure, you are OK. In a high mileage engine the oil pressure is often low at idle simply because the oil pump is turning slowly and cannot maintain higher pressure between the larger than normal crankshaft and bearing clearances. As speed increases the pump turns faster and supplies more oil and the pressure should go higher. Low pressure as long as it is only at idle is not a problem. However at higher speeds the pressure should be in the normal range. Such a worn engine can benefit from higher viscosity (thicker) oil such as 20W-50 in above freezing weather and 10W-40 in winter. That will increase idle pressure and the thicker oil film maintains a better film between the worn parts

The M61 has an elevating seat. There is a speed limit switch which consists of 2 magnets that make contact under the seat on the seat post. If the 2 magnets are together then the chair thinks the seat is all the way down. If the magnets aren't touching it activates a safety feature in the controls which cuts power to the chair by 50% hence drives real slow. Try lowering the elevating seat down through the joystick controls. If that doesn't fix it then either the magnet switches on the seat post came unplugged or broke.

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

It's the idle speed adjustment. Forward (clockwise) for faster/higher idle, back for slower.

It could either be the CV JOINT...even tho rubber looks good or it could be a front strut
