Safety Instructions
The Multi Pro 5800 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 un d e r s t a n d t h e c o ntents 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.
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.
NOTE: All of the interlock switches must be functioning
and adjusted correctly for the engine to start (see Chapter 6 − Electrical System in this manual for switch adjustment and testing information).
4. Since diesel fuel is flammable, handle it carefully:
A. Store fuel in containers specifically designed for
this purpose.
B. Do not remove machine fuel tank cap while en-
gine is hot or running.
3. Various safety interlocks incorporated into the system prevent the engine from starting unless the following conditions are met:
S The spray pump enable switch is in the OFF
position
S If an optional tank rinse kit is installed, the rinse
pump enable switch is in the OFF position
S The seat switch is depressed indicating an Operator is present, or the parking brake is engaged
S The neutral switch indicates the traction pump
is in neutral
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 and wipe up any spilled fuel.
Multi Pro 5800Page 1 − 2Safety
While Operating
Safety
1. Sit on the operators seat while the machine is in motion, or engage the parking brake during stationary operation.
2. The engine will stop running it the vehicle is operated
for more than ten seconds with the parking brake engaged.
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. Follow spray chemical manufacturer’s recommendations for handling precautions, protective equipment
and mixing proportions.
6. Before stopping the engine:
A. Ensure that traction pedal is in the NEUTRAL
position.
B. Engage the parking brake.
C. Set spray pump enable switch to the OFF posi-
tion.
D. If an optional tank rinse kit is installed, set the
rinse pump enable switch to the OFF position
7. Do not park on slopes unless wheels are chocked or
blocked.
Multi Pro 5800 Page 1 − 3 Safety
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.
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 changing attachments, tires or performing
other service, use correct supports, 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 appropriate load holding devices to support the raised machine. If the machine is
not properly supported, the machine may move or fall,
which may result in personal injury (see Jacking Instructions in this section).

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.

Inch Series Bolts and Screws
Figure 1
Using a Torque Wrench with an Offset Wrench
Use of an offset wrench (e.g. crowfoot wrench) will affect
torque wrench calibration due to the effective change of
torque wrench length. When using a torque wrench with
an offset wrench, multiply the listed torque recommendation by the calculated torque conversion factor (Fig.
3) to determine proper tightening torque. Tightening
torque when using a torque wrench with an offset
wrench will be lower than the listed torque recommendation.
Example: The measured effective length of the torque
wrench (distance from the center of the handle to the
center of the square drive) is 18”.
The measured effective length of the torque wrench with
the offset wrench installed (distance from the center of
the handle to the center of the offset wrench) is 19”.

1. Move throttle control lever on control console fully
forward to FAST position.
2. Check position of the engine speed control lever on
fuel injection pump. The speed control lever should be
contacting the high speed screw when the throttle control lever is in the fully forward FAST position.
3. If necessary, throttle cable can be adjusted by loosening cable clamp screw and repositioning cable until
speed control lever contacts high speed screw when the
throttle control lever is in the fully forward FAST position.
Tighten cable clamp screw after adjustment has been
completed.
4. After securing cable clamp, make sure that cable adjustment is still correct. Ensure the throttle swivel moves
freely and the speed control lever travels fully from stop
to stop.
