Counterbalance Pressure Test and Adjustment

Use a 500 or 1,000 PSI (35 or 70 Bar) test gauge.

Recommend counterbalance pressure:

84 inch decks: 220 PSI (15 Bar)

72 inch decks: 220 PSI (15 Bar)

Contour 82 deck: 100 – 150 PSI (7 – 10 Bar)

Brush: 225 PSI (16 Bar)

Blower: 70 – 80 PSI (5 – 6 Bar)

1.Make sure hydraulic oil is at normal operating temper- ature by operating the machine for approximately 10 minutes.

2.Lower cutting unit, engage parking brake and stop the engine.

3.Install a 500 or 1,000 PSI (35 or 70 Bar) pressure gauge with quick connect adapter on the test port.

4.Start the engine and move the throttle control all the way forward. Read the gauge. Do not raise the imple ment when testing counterbalance pressure. Move the lift lever forward to make sure the lift system is in the “float” position.
