Adjusting the
Counterbalance Pressure
The counterbalance test port
to test the pressure in the counterbalance circuit.
Recommended counterbalance pressure is 2241 kPa
(325 psi). To adjust the counterbalance pressure,
loosen the locknut, rotate the adjusting screw
(Figure
102) clockwise to increase the pressure or
counterclockwise to decrease the pressure and tighten
the locknut. The engine must be running at high idle,
the deck lowered and in float to check pressure.
Note:
The castor wheels of all three cutting units
should remain on the ground when adjusting the
counterbalance and with counterbalance applied.
