Checking The Hydraulic Lines And Hoses; Changing The Counterbalance Settings - Toro 30857N Operator's Manual

Checking the Hydraulic Lines
and Hoses
Service Interval: Before each use or daily
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.
WARNING
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.
Changing the Counterbalance
Settings
During different times of the mowing season or when turf
conditions vary, the amount of counterbalance (upward lift)
required on the cutting decks can be changed to meet the
conditions.
1. Position the machine on a level surface, lower the
cutting decks, stop the engine, engage the parking
brake, and remove the key from the ignition switch.
2. Remove the access panel below the front of the seat.
3. Locate the 2 capped counterbalance jumper wires
inside the compartment (Figure 56)

wires
4. With the key in the Off position, remove the cap from
jumper wires and plug the wires together (Figure 57).
5. Turn the key to the Run position but do not start the
machine.
6. The current counterbalance setting will flash on the
diagnostic light. The system allows for 3 settings.
7. The counterbalance setting is changed by using
the center raise-lower switch. To change the
counterbalance setting proceed as follows:
•
Moving the switch forward to the lower position
and releasing it will lower the counterbalance
setting, thus increasing the effective weight of each
cutting deck in the turf.
•
Moving the switch rearward to the raise position
and releasing it will increase the counterbalance
setting, thus decreasing the effective weight of each
cutting deck in the turf.
•
After the switch is released, the diagnostic light will
flash the new counterbalance setting (1, 2, or 3).
8. When the desired setting is attained, rotate the key to
the Off position.
9. Unplug the jumper wires, install the cap on the wires
and put the wires back into the compartment.
10. Install the access cover.
