Checking the Hydraulic Lines and
Hoses
Service Interval: Every 2 years
WARNING
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Seek immediate medical help if fluid is
injected into skin.
• Make sure that all hydraulic-fluid hoses
and lines are in good condition and all
hydraulic connections and fittings are tight
before applying pressure to the hydraulic
system.
• Keep your body and hands away from
pinhole leaks or nozzles that eject
high-pressure hydraulic fluid.
• Use cardboard or paper to find hydraulic
leaks.
• Safely relieve all pressure in the hydraulic
system before performing any work on the
hydraulic system.
Inspect the hydraulic lines and hoses daily for
leaks, kinked lines, loose mounting supports, wear,
loose fittings, weather deterioration, and chemical
deterioration. Make all necessary repairs before
operating the machine.
Adjusting the Counterbalance
Pressure
The counterbalance test port is used to test the
pressure in the counterbalance circuit
The recommended counterbalance pressure is
2241 kPa (325 psi). To adjust the counterbalance
pressure, loosen the locknut, rotate the adjusting
screw (Figure 120) clockwise to increase the pressure
or counterclockwise to decrease the pressure, and
tighten the locknut. The engine must be running and
the deck lowered and in the float position to check
the pressure.
Note:
The caster wheels of all 3 cutting units
should remain on the ground when adjusting the
counterbalance and with counterbalance applied.
