Maintenance And Service - Toro Groundsmaster 3280-D Service Manual

6. Anytime the machine is parked (short or long term),
the cutting deck (or implement) should be lowered to the
ground. This relieves pressure from the lift circuit and
eliminates the risk of the cutting deck (or implement) ac-
cidentally lowering to the ground.

Maintenance and Service

1. Before servicing or making adjustments, lower cut-
ting deck (or implement), stop engine, set parking brake
and remove key from the switch.
2. Make sure machine is in safe operating condition by
keeping all nuts, bolts and screws tight.
3. Never store the machine or fuel container inside
where there is an open flame, such as near a water heat-
er or furnace.
4. 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.
5. 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.
6. Before disconnecting or performing any work on the
hydraulic system, all pressure in the system must be re-
lieved by lowering the cutting deck (or implement) to the
ground, stopping the engine and then using all of the hy-
draulic controls (depressing the traction pedal, turning
the steering wheel and moving the lift/lower lever to both
raise and lower).
7. If major repairs are ever needed or assistance is de-
sired, contact an Authorized Toro Distributor.
8. Use care when checking or servicing the cutting
deck. Wear gloves and use caution when servicing it.
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
to make an adjustment, keep hands, feet, clothing and
other parts of the body away from the cutting deck and
other moving parts. Keep bystanders away.

7. Do not park on slopes unless wheels are chocked or
blocked.
11. Do not overspeed the engine by changing governor
setting. To assure safety and accuracy, check maximum
engine speed with a tachometer.
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 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.If welding on the machine is necessary, disconnect
the negative battery cable to prevent electrical system
damage.
17.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.
18.When changing attachments, tires or performing
other service, use correct blocks, hoists and jacks.
Make sure machine is parked on a solid level floor 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 jack stands or solid wood blocks to support
the raised machine. If the machine is not properly sup-
ported by blocks or jack stands, the machine may move
or fall, which may result in personal injury (see Jacking
Instructions in this section).
