I am sure many of you know a better way, but I have not been able to find one on this forum.
I recently cleaned and refreshed the coolant (AR8+), following the instructions in the manual. Only to be left with air coming back up from the intake tube on the motor. Try as I may, I could not get rid of that air.
Some have suggested that its okay, but I was not happy. Air means oxygen and that means rust, or corrosion.
After all sorts of attempts, this one worked for me, without having to remove any tubes of open a closed liquid system at all.
1. Turn spindle speed to zero. 2. Remove motor from the mount. (its really heavy, so keep tight hold when you release the last hex bolt) 3. Holding the motor, then lower it to a point below the reservoir. This makes the air go up, but we need it to go up from the outtake of the motor. 4. Start the spindle, (pump only as the spindle speed should be zero). 5. With the motor horizontal (like a rolling pin) and the intake tube at the upper most of the motor slowly turn the motor so the intake tube moves to the bottom. 6. And magic, the air moved into the out pipe, back to the reservoir and was released into the reservoir.
I realize it seems a little cumbersome, but now I do not have air in my system.
I have only had my AR8+ for a year and am learning, but this made me happy.
Thanks for reading and be kind with your comments.
