Maintenance and Service
1. Before servicing or making machine adjustments,
lower cutting decks, stop engine, apply parking brake
and remove key from the ignition switch.
2. Make sure machine is in safe operating condition by
keeping all nuts, bolts and screws tight.
3. Shut engine off before checking or adding oil to the
engine crankcase.
4. To reduce potential fire hazard, keep engine area
free of excessive grease, grass, leaves and dirt. Clean
protective screen on machine frequently.
5. Never store the machine or fuel container inside
where there is an open flame, suchas neara water heat-
er or furnace.
6. Do not overspeed the engine by changing governor
setting. To assuresafety and accuracy,check maximum
engine speed.
7. Disconnect batteries before servicing the machine.
Disconnect negative battery cables first and positive
cables last. If battery voltage is required for trouble-
shooting or test procedures, temporarily connect the
batteries. Reconnect positive battery cables first and
negative cables last.
8. 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.
9. Battery gases can explode. Keep cigarettes, sparks
and flames away from the battery.
10.When changing attachments, tires or performing
other service that requires the machine tobe raised, use
correct jacks, hoists and supports. Make sure machine
is parked on a solid level surface such as a concrete
floor. Prior to raising the machine, remove any attach-
ments that may interfere with the safeand properraising
of the machine.Always chock or block wheels. Use suit-
able jack stands to support the raised machine. If the
machine is not properly supported by jack stands, the
machine may move or fall, which may result in personal
injury (see Jacking Instructions in this chapter).
11.Make sure all hydraulic line connectors aretight, and
all hydraulic hoses and lines are in good condition be-
fore applying pressure to the system.
12.Keep body and hands away from pin hole leaks in hy-
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.
13.Before disconnecting or performing any work on the
hydraulic system, all pressure in system must be re-
lieved by stopping engine and lowering the cutting
decks to the ground.
14.Make sure all engine fuel system connectors and
components are correctly installed, and all fuel hoses
are in good condition before starting engine.
15.Keep bodyand hands away from leaks in engine fuel
injection lines. Use cardboard orpaper tofind high pres-
surefuelleaks if they mayexist.Leakingfuel underpres-
sure can penetrate skin and cause injury.
16.If engine must be running to perform 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.
17.At the time of manufacture, the machine conformed
to the safety s tandards for riding mowers. To assure op-
timum performance and continued safety certification of
the machine, use genuine Toro replacement parts and
accessories.Replacementparts and accessories made
by other manufacturers may result in non-conformance
with the safety standards, and the warranty may be
voided.
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. Disconnect and remove engine
electronic control module (ECM) from engine before
welding on the machine. Also, attach welder ground
cable no more than two (2) feet (0.61 meters) from the
welding location.
19.If major repairs are ever needed or assistance is de-
sired, contact an Authorized Toro Distributor.
