Introduction
Safety
Read this manual carefully to learn how to operate and
maintain your product properly. The information in this
manual can help you and others avoid injury and product
damage. Although Toro designs and produces safe
products, you are responsible for operating the product
properly and safely.
Whenever you need service, genuine Toro parts, or
additional information, contact an Authorized Service
Dealer or Toro Customer Service and have the model and
serial numbers of your product ready. Figure 1 illustrates
the location of the model and serial numbers on the
product.

1. Model & serial number plate
Write the product model and serial numbers in the space
below:
Model No.
Serial No.
The RAKE–O–VAC was designed and tested to offer
safe service when operated and maintained properly.
Although hazard control and accident prevention
partially are 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 or death. To reduce the potential for injury or
death, comply with the following safety instructions.
Since the Rake–O–Vac must be towed to operate, it is
extremely important that the tow tractor be carefully
selected to assure the best performance and safe operation.
The tow tractor must have the proper wheel base and tread
width and equipped with a roll bar and seat belt to operate
safely on hilly terrain. The normal operating speed is 6 mph
but will vary with terrain and debris being picked up. The
maximum transport speed is 20 mph with slower speeds
required on hilly terrain. Refer to tractor Operator’s Manual
for information or tractor service agency if you have any
question on safe operation.
The brakes of the tow tractor must have the capacity to stop
the Rake–O–Vac with hopper fully loaded and traveling at
the maximum recommended transport speed.
The power take–off drive of the Rake–O–Vac requires a
tractor with operating speeds of 540 rpm and output power
of 20 hp or higher. Do not exceed the 540 rpm speed.
The Rake–O–Vac must comply with local road
requirements, if transported on public roads. A
Slow–moving vehicle sign has been provided. Signal lights
and brakes are not provided and may be required in some
areas.
This manual identifies potential hazards and has special
safety messages that help you and others avoid personal
injury and even death. Danger, Warning, and Caution are
signal words used to identify the level of hazard. However,
regardless of the hazard, be extremely careful.
Danger signals an extreme hazard that will cause serious
injury or death if you do not follow the recommended
precautions.
Warning signals a hazard that may cause serious injury or
death if you do not follow the recommended precautions.
Caution signals a hazard that may cause minor or moderate
injury if you do not follow the recommended precautions.
This manual uses two other words to highlight information.
Important calls attention to special mechanical
information and Note: emphasizes general information
worthy of special attention.
Before Operating
• Operate the machine only after reading and
understanding the contents of this manual. A
replacement manual is available by sending complete
model and serial number to:
The Toro Company
8111 Lyndale Avenue South
Bloomington, Minnesota 55420–1196.
• Never allow children to operate the machine or adults to
operate it without proper instructions.
• Become familiar with the controls and know how to
stop the engine/sweeper quickly.
• Keep all shields, safety devices and decals in place. If a
shield, safety device or decal is malfunctioning,
illegible, or damaged, repair or replace it before
operating the machine.
3
• Always wear substantial shoes. Do not operate machine
while wearing sandals, tennis shoes or sneakers. Do not
wear loose fitting clothing which could get caught in
moving parts and cause personal injury.
– Shut engine off and wait for all movement to stop.
The impeller may momentarily turn after other
components have stopped. Use extreme caution
when removing cover from blower housing.
• Wearing safety glasses, safety shoes, long pants and a
helmet is advisable and required by some local safety
and insurance regulations.
• Keep everyone, especially children and pets away from
the areas of operation.
• Since gasoline is highly flammable, handle it carefully.
– Use an approved gasoline container.
– Do not remove cap from fuel tank when engine is
hot or running.
– Do not smoke while handling gasoline.
– Fill fuel tank outdoors and to about one inch below
top of tank, (bottom of filler neck). Do not overfill.
– Wipe up any spilled gasoline.
While Operating
• Exhaust fumes are hazardous and could be deadly, so do
not run the engine in a confined area without adequate
ventilation.
• This product may exceed noise levels of 85 dB(A) at
the operator position. Ear protectors are recommended,
for prolonged exposure, to reduce the potential of
permanent hearing damage.
• Never carry passengers on prime mover or allow
anyone to ride on sweeper.
• Disengage clutch before starting sweeper engine.
• Using the machine demands attention. To prevent
tipping or loss of control:
– Use extreme caution around ditches, creeks or other
hazards.
– Watch for holes or other hidden hazards.
– Use caution when operating machine on a steep
slope. Reduce speed when making sharp turns or
when turning on hillsides.
– Avoid sudden stops and starts.
– Before backing up, look to the rear and assure no
one is behind the machine.
– Watch out for traffic when near or crossing roads.
Always yield the right of way.
• Before leaving operator position:
– Shift into neutral, stop prime mover and engage
parking brake.
– Disengage and lower sweeper implement.
– Shut sweeper engine off.
– Disengage P.T.O.
– Take precautions to prevent accidental starts, rolling
away, etc.
• Do not step over P.T.O. shaft to get to other side of
machine. Walk around sweeper.
• Never get on or off prime mover with P.T.O. shaft
engaged.
• If prime mover or sweeper ever vibrate abnormally,
stop immediately, turn engine off, wait for all motion to
stop and inspect for damage. Repair all damage before
commencing operation.
• Whenever machine is left unattended, be sure engine is
stopped, implement is lowered and key is removed from
ignition switch.
• Shut sweeper blower off when dumping contents of
hopper. Always stand to extreme right or left side of
hopper when opening tailgate.
• Park on a level surface, empty hopper and block wheels
before removing sweeper from prime mover.
Maintenance
• Disengage power to sweeper implement and stop engine
before servicing or making adjustments.
• Disengage power to sweeper implement and stop engine
when transporting or not in use.
• To make sure entire machine is in good condition, keep
all nuts, bolts and screws properly tightened.
• If major repairs are ever needed or assistance is
required, contact an Authorized TORO Distributor.
• To reduce potential fire hazard, keep the engine area
free of excessive grease, grass, leaves and accumulation
of dirt.
• 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.
• Do not overspeed engine by changing governor settings.
To assure safety and accuracy, have an Authorized Toro
Distributor check maximum engine speed with a
tachometer. P.T.O. driven machines must not exceed
540 R.P.M.
4
• Engine must be shut off before checking oil or adding
oil to the crankcase.
• Check prime mover brakes periodically to be sure
brakes, when applied, will hold firmly. Also, check to
make sure all safety equipment is functioning properly.
Safety and Instruction Decals
Safety decals and instructions are easily visible to the operator and are located near any area
of potential danger. Replace any decal that is damaged or lost.

resulting in personal injury.
• When removing or installing the battery, do not
allow the battery terminals to touch any metal
parts of the tractor.
• Do not allow metal tools to short between the
battery terminals and metal parts of the tractor.
2. Attach the negative cable (wire from engine block) to
the negative (–) terminal of the battery.
Warning
Incorrect battery cable routing could damage the
tractor and cables causing sparks. Sparks can
cause the battery gasses to explode, resulting in
personal injury.
• Always disconnect the negative (black) battery
cable before disconnecting the positive (red)
cable.
• Always connect the positive (red) battery cable
before connecting the negative (black) cable.
