be necessary to bleed the system if fluid is changed or
after work is performed on the system.
1. Raise rear of the machine so wheels are off the
ground and support with jack stands.
2. Start the engine and run at idle speed. Engage
traction on one side and spin the wheel by hand.
3. When the wheel begins to spin on its own, keep
it engaged until wheel drives smoothly.
(minimum 2 minute)
