1 1. Exhaust fumes are hazardous and could be deadly,
so do not run the engine in a confined area without ade
quate ventilation.
12. Sit on seat when operating the machine. Never
carry passengers.
13. When starting the engine:
A. Make sure traction pedal is released.
B. After the engine is started, keep foot off traction
pedal. Machine must not move. If movement is evi
dent, the neutral return mechanism is adjusted incorrectly; therefore, shut engine off and readjust
mechanism so machine does not move when in
neutral position. If engine does not start, check in
terlock switch connections.
14. Using the machine demands attention. To prevent
tipping or loss of control:
A. Use care when entering and leaving sand traps.

engine is running or soon after it has stopped because
these areas are hot enough to cause burns.
17. If the machine ever vibrates abnormally, stop immediately , turn engine off, wait for all motion to stop and
inspect for damage. Repair all damage before com
mencing operation.
18. Before getting off the seat:
A. Stop movement of the machine.
B. Set parking brake and lower attachments to the

Maintenance and Service
20. Before servicing or making adjustments to the machine, stop engine, remove key from the ignition, and
pull the spark plug wire off spark plug to prevent acci
dental starting of the engine.
21. 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.
22. 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 suffi
cient force to penetrate skin and do serious damage. If
fluid is injected into the skin it must be surgically re
moved within a few hours by a doctor familiar with this
form of injury or gangrene may result.
23. Before disconnecting or performing any work on the
hydraulic system, all pressure in system must be re
lieved by stopping engine, engaging parking brake and
lowering attachments to the ground.
24. To make sure entire machine is in good condition,
keep all nuts, bolts and screws properly tightened.
25. If major repairs are ever needed or assistance is required, contact an Authorized TORO Distributor.
26. To reduce potential fire hazard, keep the engine
area free of excessive grease, grass, leaves and accu
mulation of dirt.
27. 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 any moving
parts. Keep everyone away.
28. Do not overspeed engine by changing governor settings. Maximum engine speed is 3200 rpm. To assure
safety and accuracy , have an Authorized Toro Distribu
tor check maximum engine speed with a tachometer.
29. Engine must be shut off before checking oil or adding oil to the crankcase.
-
30. To be sure of optimum performance and safety, always purchase genuine TORO replacement parts and
accessories. Replacement parts and accessories made
by other manufacturers could be dangerous. Such use
could void the product warranty of The Toro Company.
31. 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. Used jack stands or solid wood blocks to sup
port 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.

Sand Pro 2020/3020/5020 Page 3 – 1 Engine
Introduction
This Chapter gives information about specifications,
maintenance, troubleshooting, testing, and repair of the
gasoline engines used in the Sand Pro 2020, 3020, and
5020.
Most repairs and adjustments require tools which are
commonly available in many service shops. Special
tools are described in the Briggs and Stratton V anguard
Repair and Service Manual for 4–Cycle V–Twin Cylin
der OHV Engines. 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 fa
cility .
Service and repair parts for Briggs and Stratton Vanguard engines are supplied through your local Briggs
and Stratton dealer or distributor. If no parts list is avail
able, be sure to provide your distributor with the Toro
model and serial number.

General Information
Check Engine Oil
CAUTION
Before servicing or making adjustments to the
machine, make sure of the following: stop engine, engage parking brake, lower attachment,
and remove key from the switch.
2
IMPORTANT: Check oil level every 8 operating
hours or daily. Change oil initially after the first 8
hours of operation. Thereafter, change oil every 25
hours and filter every 100 hours under normal con
ditions. Change oil more frequently when the engine is operated in extremely dusty or dirty
conditions.
The engine is shipped with 1–3/4 quarts (w/ filter) of oil
in the crankcase; however, oil level must be checked be
fore and after the engine is first started.
1. Position machine on a level surface.
2. Unscrew dipstick and wipe it with a clean rag. Screw
dipstick into the tube, and make sure it is seated fully.
Unscrew dipstick out of the tube. Check oil level. If oil
level is low, remove filler cap from the valve cover (next
to dipstick), and add enough oil to raise the level to the
FULL mark on the dipstick.

3. The engine uses any high-quality detergent oil having the American Petroleum Institute -API- “service classification” SE, SF or SG. Recommended viscosity
(weight) is SAE 30.
IMPORTANT: Dipstick must be fully seated in tube
to provide proper sealing of engine crankcase. Fail
ure to seal crankcase may result in engine damage.
4. Install dipstick firmly into the tube.

Fill Fuel Tank
IMPORTANT: The Toro Company strongly recommends using fresh, clean, unleaded
gasoline in Toro gasoline powered products. Un
leaded gasoline burns cleaner, extends engine life,
and promotes good starting by reducing the build–
up of combustion chamber deposits. Leaded gaso
line can be used if unleaded is not available.
IMPORTANT: Never use methanol, gasoline containing methanol, gasoline containing more than
10% ethanol, gasoline additives, premium gasoline,
or white gas. Damage may result to engine fuel sys
tem.
NOTE: Fuel tank capacity is about 4.25 gallons for the
SP 2020/3020 and 5.5 gallons for the SP 5020.
1. Clean area around fuel tank cap.
2. Remove fuel tank cap.
3. Fill tank about one inch below top of the tank, (bottom of filler neck). DO NOT OVERFILL. Then install cap.
4. Prevent a fire hazard. Wipe up any spilled fuel.
regular grade
Gasoline is flammable; use caution when storing
-
-
or handling it. Do not fill fuel tank while the engine is running, hot, or when machine is in an enclosed area. V apors may build up, and can be ignited by a spark or flame source many feet away .
Prevent the possibility of an explosion. DO NOT
SMOKE while filling the fuel tank. Always fill fuel
tank outside. Wipe up any spilled gasoline before
starting the engine. Use a funnel or spout to prevent spilling gasoline. Fill tank no higher than
one inch below top of tank, (bottom of filler neck).
DO NOT OVER FILL. Store gasoline in a clean
safety approved container and keep the cap on
the container. Keep gasoline in a cool, well–ventilated place; never store in an enclosed area
such as a hot storage shed. To assure volatility,
do not buy more than a 30 day supply of gasoline.
Gasoline is a fuel for internal combustion engines; do not use it for any other purpose. Many
children like the smell of gas, so keep it out of
their reach. Gas fumes are explosive and dangerous to inhale.
