Safety Instructions
The Sand Pro and Infield Pro are 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 quickly. A replacement Operator’s Manual is
available on the Internet at www.Toro.com or by sending
the complete model and serial number to:
The Toro Company
Attn. Technical Publications
8111 Lyndale Avenue South
Bloomington, Minnesota 55420–1196
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.
4. Ensure that the traction interlock switch is adjusted
correctly so the engine cannot be started unless the
traction pedal is released and in the neutral position.
5. Since gasoline 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.
3. Wearing safety glasses, safety shoes, long pants
and a helmet is advisable and required by some local
safety and insurance regulations.
While Operating
1. Operator should be in the operator’s seat when operating the Sand Pro and Infield Pro. Never carry passengers.
2. Do not run engine in a confined area without adequate ventilation. Exhaust fumes are hazardous and
could possibly be deadly.
3. Do not touch engine, muffler or exhaust system while
engine is running or soon after it is stopped. These
areas could be hot enough to cause burns.
4. If abnormal vibration is detected, stop machine immediately and determine source of vibration. Correct
problems before resuming the use of the machine.
E. If fuel is spilled, do not start engine. Move the machine away from the area of spillage and allow the
gasoline vapors to dissipate. Properly dispose of any
spilled fuel.
5. While operating, the machine may exceed noise levels of 85 dB(A) at the operator position. Hearing protection is recommended for prolonged exposure to reduce
the potential of permanent hearing damage.
6. Before leaving the operator’s position of the machine:
A. Stop movement of the machine.
B. Apply parking brake and lower attachment(s) to
the ground. Take precautions to prevent accidental
starts, rolling away, etc.
Safety
Page 1 – 2
Sand Pro & Infield Pro 3040/5040
Maintenance and Service
1. Before servicing or making adjustments, position
machine on a level surface and apply parking brake to
prevent machine from moving.
2. Before servicing or making adjustments, disconnect
the spark plug wires from the spark plugs and position
the wires away from the spark plugs to ensure that the
engine will not start unexpectedly.
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 system line connectors are
tight and all hydraulic system hoses and lines are in
good condition before applying pressure to the hydraulic
system.
6. Before disconnecting any hydraulic component or
performing any work on the hydraulic system, all pressure in hydraulic system must be relieved.
7. Keep body and hands away from pin hole leaks or
nozzles that eject hydraulic fluid under high pressure.
Use paper or cardboard, not hands, to search for leaks.
Hydraulic fluid escaping under pressure can have sufficient force to penetrate skin and do serious damage. If
fluid is injected into the skin it must be surgically removed within a few hours by a doctor familiar with this
form of injury or gangrene may result.
8. Do not overspeed the engine by changing governor
setting. To assure safety and accuracy, check maximum
engine speed with a tachometer.
9. Shut engine off before checking or adding oil to the
engine crankcase.
10.To reduce potential fire hazard, keep engine area
free of excessive grease, grass, leaves and dirt.
11. If the engine must be running to perform a maintenance adjustment, keep hands, feet, clothing and any
parts of the body away from the engine and all moving
parts. Also, keep bystanders away.
12.When changing tires or performing other service that
requires the machine to be raised off the ground, make
sure machine is properly supported. If the machine is
not properly supported, the machine may move or fall,
which may result in personal injury.
13.If major repairs are ever needed or assistance is desired, contact an Authorized Toro Distributor.
14.At the time of manufacture, the machine conformed
to all applicable safety standards. To assure optimum
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.

Jacking Instructions
CAUTION
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 supported by
blocks or jack stands, the machine may move
or fall, which may result in personal injury.
Use the following positions when jacking up the machine:
Front End Jacking
1. Jack the front of the machine from the bottom of the
frame behind the front wheel (Fig. 1). Make sure that
jack is positioned directly under frame to prevent damage to oil cooler.

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
(e.g. Nylock nut), hardness of the surface underneath
the fastener’s head or similar condition which affects the
installation.
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.

Introduction
This Chapter gives information about specifications,
maintenance, troubleshooting, testing and repair of the
Briggs and Stratton gasoline engine used in Sand Pro
and Infield Pro machines.
Most repairs and adjustments require tools which are
commonly available in many service shops. Special
tools are described in the Briggs and Stratton Repair
Manual that is included at the end of this Chapter. The
use of some specialized test equipment is explained.
However, the cost of the test equipment and the specialized nature of some repairs may dictate that the work be
done at an engine repair facility.
Service and repair parts for the Briggs and Stratton engine used to power the Sand Pro or Infield Pro are supplied through your local Toro distributor or your local
Briggs and Stratton dealer or distributor. If no parts list
is available, be prepared to provide your distributor with
the Toro equipment model and serial numbers as well as
the Briggs and Stratton engine model and serial numbers.
