Checking the Hydraulic Lines
and Hoses
Service Interval: Every 2 years
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.
Hydraulic fluid escaping under pressure can
penetrate skin and cause injury.
• Make sure 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 pin
hole 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.
• Seek immediate medical attention if fluid
is injected into skin.
Adjusting the Counterbalance
Pressure
The counterbalance test port (Figure 76) is used
to test the pressure in the counterbalance circuit.
Recommended counterbalance pressure is 470 psi (3241
kPa). To adjust the counterbalance pressure, loosen the
locknut, rotate the adjusting screw (Figure 76) clockwise
to increase the pressure or counterclockwise to decrease
the pressure and tighten the locknut
Note: All three side cutting units castor wheels should
remain on the ground with counterbalance applied.
