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.
