3. Remove the filter.
4. Lubricate the gasket on the new filter with hydraulic oil.
5. Ensure that the filter mounting area is clean.
6. Install the filter by hand until the gasket contacts the
mounting surface, then rotate it an additional 1/2 turn.
7. Repeat the procedure on the other filter.
8. Start the engine and let it run for about two minutes to
purge air from the system.
9. Stop the engine and check for leaks.
Checking the Hydraulic Lines
and Hoses
Daily, check hydraulic lines and hoses 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.
• Get immediate medical help 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. Unlatch and remove the access panel from the side of
the control arm.
3. Locate the two capped counterbalance jumper wires
inside the compartment (Figure 59).
