Safety Instructions
The Multi Pro 5700--D Turf Sprayer is designed and
tested to offer safe service when operated and maintained properly. Although hazard control and accident
prevention are partially dependent upon the design and
configuration of the machine, these factors are also dependent upon the awareness, concern, and proper
training of the personnel involved in the operation, transport, maintenance, and storage of the machine. Improper use or maintenance of the machine can result in injury
Before Operating
1. Read and understand the contents of the Operator’s
Manual before starting and operating the machine. Become familiar with the controls and know how to stop the
machine and engine quickly. Additional copies of the
Operator’s Manual are available on the internet at
www.Toro.com.
2. Keep all shields, safety devices, and decals in place.
If a shield, safety device, or decal is defective, illegible
or damaged, repair or replace it before operating the
machine. Also tighten any loose nuts, bolts or screws to
ensure machine is in safe operating condition.
3. Assure interlock switches are adjusted correctly so
engine cannot be started unless traction pedal is in the
NEUTRAL position.
or death. To reduce the potential for injury or death,
comply with the following safety instructions.
WARNING
To reduce the potential for injury or death,
comply with the following safety instructions.
4. Since diesel fuel is highly flammable, handle it carefully:
A. Store fuel in containers specifically designed for
this purpose.
B. Do not remove machine fuel tank cap while engine is hot or running.
C. Do not smoke while handling fuel.
D. Fill fuel tank outdoors and only to within an inch of
the top of the tank, not the filler neck. Do not overfill
the fuel tank.
E. Wipe up any spilled fuel.
While Operating
1. Sit on the seat when starting and operating the machine.
2. Before starting the engine:
A. Engage the parking brake.
B. Make sure traction pedal is in theNEUTRAL position and the pump switch is OFF.
3. Do not run engine in a confined area without adequate ventilation. Exhaust fumes are hazardous and
could possibly be deadly.
4. Do not touch engine, radiator, muffler or exhaust
pipe while engine is running or soon after it is stopped.
These areas could be hot enough to cause burns.
5. Before getting off the seat:
A. Ensure that traction pedal is in the NEUTRAL
position.
B. Set parking brake.
C. Turn pump switch OFF.
D. Stop engine and remove key from ignition switch.
E. Do not park on slopes unless wheels are chocked

Maintenance and Service
1. Before servicing or making adjustments, turn spray
pump off, put traction pedal in neutral, stop engine, set
parking brake, and remove key from the 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 protective 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 heater or furnace.
5. Make sure all hydraulic line connectors are tight and
that all hydraulic hoses and lines are in good condition,
before applying pressure to the system.
6. Keep body and hands away from pin hole leaks in hydraulic 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 doctor familiar with this form of injury or gangrene may result.
10.If engine must be running to perform maintenance or
an adjustment, keep clothing, hands, feet, and other
parts of the body away from moving parts. Keep bystanders away.
11. Do not overspeed the engine. 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 troubleshooting 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.To assure optimum performance and continued
safety of the machine, use genuine Toro replacement
parts and accessories. Replacement parts and accessories made by other manufacturers may result in nonconformance with safety standards, and the warranty
may be voided.
Safety
7. Before disconnecting or performing any work on the
hydraulic system, all pressure in hydraulic system must
be relieved. To relieve system pressure, rotate steering
wheel in both directions after the key switch has been
turned off.
8. If major repairs are ever needed or assistance is desired, 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.
17.When raising the machine to change tires or to perform other service, use correct blocks, hoists, and jacks.
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 jack stands or solid wood blocks to
support the raised machine. If the machine is not properly supported by blocks or jack stands, the machine
may move or fall, which may result in personal injury
(see Jacking Instructions in this Chapter).

Torque Specifications
Recommended fastener torque values are listed in the
following tables. For critical applications, as determined
by Toro, either the recommended torque or a torque that
is unique to the application is clearly identified and specified in this Service Manual.
These Torque Specifications for the installation and
tightening of fasteners shall apply to all fasteners which
do not have a specific requirement identified in this Service Manual. The following factors shall be considered
when applying torque: cleanliness of the fastener, use
of a thread sealant (e.g. Loctite), degree of lubrication
on the fastener, presence of a prevailing torque feature,
hardness of the surface underneath the fastener’s head,
or similar condition which affects the installation.
Fastener Identification
As noted in the following tables, torque values should be
reduced by 25% for lubricated fasteners to achieve
the similar stress as a dry fastener. Torque values may
also have to be reduced when the fastener is threaded
into aluminum or brass. The specific torque value
should be determined based on the aluminum or brass
material strength, fastener size, length of thread engagement, etc.
The standard method of verifying torque shall be performed by marking a line on the fastener (head or nut)
and mating part, then back off fastener 1/4 of a turn.
Measure the torque required to tighten the fastener until
the lines match up.

DANGER
Because diesel fuel is highly flammable, use
caution when storing or handling it. Do not
smoke while filling the fuel tank. Do not fill fuel
tank while engine is running, hot or when machine is in an enclosed area. Always fill fuel tank
outside and wipe up any spilled fuel before starting the engine. Store fuel in a clean, safety--approved container and keep cap in place. Use diesel fuel for the engine only; not for any other
purpose.
Check Fuel Lines and Connections
Check fuel lines and connections periodically as recommended in the Operator’s Manual. Check lines for deterioration, damage, leaks or loose connections. Replace
hoses, clamps and connections as necessary.
Empty and Clean Fuel Tank
Empty and clean the fuel tank if the fuel system becomes contaminated or if the machine is to be stored for
an extended period.
To clean fuel tank, flush tank out with clean solvent.
Make sure tank is free of contaminates and debris.
