Maintenance And Service - Toro Multi Pro 1750 Service Manual

Maintenance and Service

1. Before servicing or making adjustments, turn spray
pump off, put range selector in NEUTRAL, stop engine,
apply parking brake and remove key from the ignition
switch.
2. Prior to servicing sprayer components, determine
what chemical(s) have been used in the sprayer. Follow
precautions and recommendations printed on chemical
container labels or Material Safety Data Sheets when
servicing sprayer components. Use appropriate protec-
tive equipment: protective clothing, chemical resistant
gloves and eye protection.
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 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 the system must be re-
lieved. To relieve system pressure, park machine on a
level surface, engage parking brake and fully raise the
spray booms so they are resting in the boom cradles.
Shut engine off. Turn ignition key to the RUN position
(do not start engine) and press both boom lift switches
to the raise and lower positions to relieve hydraulic pres-
sure in the boom lift circuits. Then, turn ignition key to
the STOP position and rotate steering wheel in both di-
rections to relieve hydraulic pressure in the steering cir-
cuit.
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 moving parts. Keep by-
standers 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
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.
IMPORTANT: Before performing welding on the ma-
chine, disconnect both positive and negative bat-
tery cables from the battery, disconnect the wire
harness connector from the TEC and disconnect
the terminal connector from the engine alternator.
These steps will prevent damage to the machine
electrical system when welding.
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.To assure optimum performance and continued
safety of the machine, use genuine Toro replacement
parts and accessories. Replacement parts and acces-
sories made by other manufacturers may result in non-
conformance with the safety standards and the warran-
ty may be voided.
17.When changing attachments, tires or performing
other service, use correct jacks, hoists and jack stands.
Make sure machine is parked on a solid level surface
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 jack stands to support the raised ma-
chine. 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 chap-
ter).
18.Make sure to dispose of potentially harmful waste
(e.g. fuel, oil, filters, battery) in an environmentally safe
manner. Follow all local codes and regulations when re-
cycling or disposing of waste.
