Robinair 34788 display contrast adjustment?
The Robinair 34788 is an automotive air conditioning service machine that features a large, easy-to-read display. If the display on your 34788 machine appears dim or the contrast is not suitable, it is possible to adjust the display contrast to improve visibility. Here are the steps to adjust the contrast on the Robinair 34788:
- Turn on the machine and wait for the display to fully light up.
- Press and hold the "Enter" and "Clear" buttons simultaneously for three seconds.
- The display will show "Contrast" and the current contrast setting.
- Use the "+" and "-" buttons to adjust the contrast to your desired level.
- Once you have set the contrast level, press the "Enter" button to save the setting.
- The display will show "Contrast Saved" to confirm that the new setting has been saved.
If you are still experiencing difficulty with the display after adjusting the contrast, there may be an issue with the machine's internal components or the display itself. In this case, it is recommended that you contact a qualified service technician for assistance.

I have an Acurite 822-RX thermometer that shows HH
HH means it is showing the high temperature you (most likely accidentally) set with the MAX MIN / + button, which is easy to do when setting the clock. Just press that button again until the reading appears.

Replace the fuel lines. I had the same problem with one of my riders. The inside of the fuel lines had rotted and they were collapsing when they tried to suck the gas through them.
New lines and it ran all day!
