Maintenance and Service
1. The Traction Unit and Cutting Deck Operator’s
Manuals provide information regarding the operation,
general maintenance and maintenance intervals for
your Groundsmaster machine. Refer to these publica-
tions for ad ditional information when servicing the ma-
chine.
2. Before servicing or making adjustments, lower cut-
ting decks, stop engine, set parking brake and remove
key from the ignition switch.
3. Make sure machine is in safe operating condition by
keeping all nuts, bolts and screws tight.
4. Never store the machine or fuel container inside
where there is an open flame, such asnear a water heat-
er or furnace.
5. Make sure all hydraulic line connectors are tight and
all hydraulic hoses and lines are in good condition be-
fore applying pressure to the hydraulic system.
6. Keep body and hands away from pin hole leaks inhy-
draulic lines that eject high pressure hydraulic fluid. Use
cardboard or paper to find hydraulic leaks. Hydraulic
fluid escaping under pressure can penetrate skin and
cause injury. Fluid accidentally injected into the skin
must be surgically removed within a few hours by a doc-
tor familiar with this form of injury or gangrene may re-
sult.
7. Before disconnecting or performing any work on the
hydraulic system, all pressure in system must be re-
lieved by stopping engine and lowering cutting decks to
the ground.
8. If major repairs are ever needed or assistance is de-
sired, contact an Authorized Toro Distributor.
9. To reduce potential fire hazard, keep engine area
free of excessive grease, grass, leaves and dirt. Clean
protective screen on machine frequently.
10.If engine must be running toperform maintenance or
an adjustment, keep hands, feet, clothing and other
parts of the body away from cutting decks and other
moving parts. Keep bystanders away.
11.To assure safety and accuracy, check that maximum
engine speed is correct.
12.Shut engine off before checking or adding oil to the
crankcase.
13.Disconnect battery before servicing the machine.
Disconnect negative battery cable first and positive
cable last. If battery voltage is required for troubleshoot-
ing or test procedures, temporarily connect the battery.
Reconnect positive battery cable first and negative
cable last.
14.Battery acid is poisonous and can cause burns.
Avoid contact with skin, eyes and clothing. Protect your
face, eyes and clothing when working with a battery.
15.Battery gases can explode. Keep cigarettes, sparks
and flames away from the battery.
16.At the time of manufacture, the machine conformed
to the safety standards for riding mowers. To assure op-
timum performance and continued safety certification of
the machine, use genuine Toro replacement parts and
accessories. Replacement partsandaccessoriesmade
by other manufacturers may result in non-conformance
with the safety standards and the warranty may be
voided.
17.When changing attachments, tires or performing
other service, use correct jacks, hoists and jack stands.
Make sure machine is parkedonasolidlevelsurface
such as a concrete floor. Prior to raising the machine, re-
move any attachments that may interfere with the safe
and proper raising of the machine. Always chock or
block wheels. Use appropriate jack stands to support
the raised machine. If the machine is not properly sup-
ported by jack stands, the machine may move or fall,
which may result in personal injury (see Jacking Instruc-
tions in this chapter).
18.When welding on machine, disconnect all battery
cables to prevent damage to machine electronic equip-
ment. Disconnect negative battery cable first and posi-
tive cable last. Also, disconnect wire harness connector
from the TEC controller(s), disconnect and remove the
engine ECUand disconnectthe terminal connector from
the alternator. Attach welder ground cable n o more than
two ( 2) feet (0.6 meters) from the welding location.
19.Make sure to dispose of potentially harmful waste
(e.g. fuel, oil, engine coolant, filters, battery) in an envir-
onmentally safe manner. Follow all local codes and r eg-
ulations when recycling or disposing of waste.
