Jacking Instructions 1; Maintenance And Service - Toro Greensmaster TriFlex 3320/3420 Service Manual

Maintenance and Service

1. The Traction Unit and Cutting Unit Operator's Manu-
als provide information regarding the operation, general
maintenance and maintenance intervals for your
Greensmaster machine. Refer to these publications for
additional information when servicing the machine.
2. Before servicing or making adjustments, lower cut-
ting units, place functional control lever in the neutral
position, stop engine, apply 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 as near 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 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.
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 units 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 to perform maintenance or
an adjustment, keep hands, feet, clothing and other
parts of the body away from cutting units and other mov-
ing parts. Keep bystanders away.
11. Do not overspeed the engine by changing governor
setting. To assure safety and accuracy, check maximum
engine speed.
12.Shut engine off before checking or adding oil to the
engine crankcase.
Safety
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.Before installing, removing or working on the cutting
units, disconnect the cutting units from the electrical
power supply by separating the cutting unit power dis-
connect couplers. The couplers are located at the base
of the rollover bar on the left side of the traction unit.
Connect the couplers together before operating the ma-
chine.
15.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.
16.Battery gases can explode. Keep cigarettes, sparks
and flames away from the battery.
17.When welding on machine, disconnect both battery
cables to prevent damage to machine electronic equip-
ment. Disconnect negative battery cable first and posi-
tive cable last. Also, disconnect the wire harness
connector from the TEC controller and the alternator
connector(s). This will prevent damage to the electrical
system of your Greensmaster.
18.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 parts and accessories made
by other manufacturers may result in non-conformance
with the safety standards and the warranty may be
voided.
19.When changing attachments, tires or performing
other service, use correct jacks and supports. Make
sure machine is parked on a solid level surface such as
a concrete floor. Prior to raising the machine, remove
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 supported
by jack stands, the machine may move or fall, which may
result in personal injury (see Jacking Instructions in this
chapter).
