Sprayer and Spreader Operation
Safety
• Stop the machine, shut off the engine, remove
the key, engage the parking brake, and inspect
for damage after striking an object or if there is
an abnormal vibration in the machine. Make all
necessary repairs before resuming operation.
• The spray wand traps liquids under high pressure,
• Slow down and use caution when making turns
and crossing roads and sidewalks with the
machine. Always yield the right-of-way.
• Use extra caution when operating the machine on
wet surfaces, in adverse weather conditions, at
higher speeds, or with a full load. Stopping time
and distance increase in these conditions.
• Never run an engine in an enclosed area where
exhaust gasses can collect.
• Never leave a running machine unattended.
• Do not touch the engine or muffler while the engine
is running or soon after it has shut off. These
areas may be hot enough to cause burns.
• Before leaving the operating position, do the
•
following:
– Stop the machine on level ground.
•
– Shut the wide-distribution impeller-gate for the
spreader and shut off the sprayer-pump switch.
•
– Shut off the engine and remove the key.
– Engage the parking brake.
•
– Wait for all moving parts to stop.
• Do not operate the machine when there is the risk
of lightning.
• Do not use the machine as a towing vehicle.
•
• Do not change the governor speed or overspeed
the engine.
•
• Use accessories and attachments approved by

could cause serious injury or death.
– Keep clear of nozzle and do not direct spray
or stream at people, pets, or non-work area
property.
– Do not direct spray on or near electrical-power
components or source.
– Do not attach hoses or other components to
the end of the spray-wand nozzle.
– Do not attempt to disconnect the spray
wand from the machine while the system is
pressurized.
– Do not use spray wand if trigger lock is
damaged or missing.
– Rotate the spray-wand lock to the OFF position
when job is complete.
Do not touch the impeller for the spreader while
the impeller is rotating.
Stop spreading/spraying when making tight turns
to minimize chemical drift.
Chemicals may drift and cause injury to people
and animals; it may also damage plants, soil, or
other property.
Liquid loads and granular materials can shift. This
shifting happens most often while turning, going
up or down hills, suddenly changing speeds, or
while driving over rough surfaces. Shifting loads
can cause the machine to tip over.
Safely relieve pressure from spray wand every
time the engine is shut off.
When draining or relieving system, do not let
anyone stand in front of nozzles and do not drain
on a person’s feet.
Slope Safety
Slopes are a major factor related to loss of control and
rollover accidents, which can result in severe injury or
death. You are responsible for safe slope operation.
Operating the machine on any slope requires extra
caution.
• Review the slope instructions listed below for
operating the machine on slopes and to determine
whether you can operate the machine in the
conditions on that day and at that job site.
Changes in the terrain can result in a change in
slope operation for the machine.
• Determine if the slope is safe for machine
operation, including surveying the site. Always
use common sense and good judgment when
performing this survey.
20
Operating the Machine
• Avoid starting, stopping, or turning the machine
on slopes. Travel up and down on slopes. Avoid
making sudden changes in speed or direction.
If you must turn the machine, turn it slowly and
gradually downhill, if possible. Use care when
reversing the machine.

• Be aware that operating the machine on wet
surfaces, across slopes, or downhill may cause
the machine to lose traction. Loss of traction to the
wheels may result in sliding and a loss of braking
and steering.
• Use extreme caution when operating the machine
near drop-offs, ditches, embankments, water
hazards, or other hazards. The machine could
suddenly roll over if a wheel goes over the edge
or the edge caves in. Establish a safety area
between the machine and any hazard.
• Use extra care while operating the machine with
attachments; they can affect the stability of the
machine.
• If the engine stalls or you begin to lose momentum
while climbing a hill, gradually apply the brakes
and slowly back straight down the hill.
• Always keep the transmission in gear (if applicable)
when you drive the machine down a slope.

Calibrating the Spreader
• For small granule materials:
Calibrate the spreader each time you use a new
material. The spreader broadcasts material in a
pattern 1.5 to 6.7 m (5 to 22 ft) wide depending on the
material particle size, volume/density, rate of travel,
and wind conditions.
Place 6 additional pans, on each side, with
no gap in between each pan (Figure 24).
Use the Spreading Charts (page 30) along with
information from Determining the Distribution Pattern
(page 25), Determining the Effective Spreading Width
(page 25), and Calculating the Application Rate (page
26) when calibrating the spreader.

of Figure 32.
Adjust the spreader pattern as follows:
• If the material is broadcast too heavy
at the left side of the machine, pull the
spreader-pattern control up slightly; refer to
3 of Figure 32.
• If the material is broadcast too heavy at
the right side of the machine, push the
spreader-pattern control down slightly; refer
to 4 of Figure 32.

Spreading Material
Lock the spreader-pattern control by turning the
handle clockwise 90°; refer to 5 of Figure 32.
Using the Deflector Gate
Use the deflector-gate control to temporarily stop or
deflect granular material away from sidewalks, parking
lots, patios, or anywhere the granular chemicals are
not desired.
1.
Start the engine and place the throttle midway
between the SLOW and the FAST positions.
2.
Set the impeller-speed control to appropriate
broadcast rate and then press the impeller
On/Off switch to the ON position (Figure 34).
Note: The deflector gate changes the discharged of
materials from the left side of the spreader only.
• Push the knob for the deflector-gate control down
to lower the deflector and temporarily block the
granular material.
• Pull the knob to raise the deflector to cast materials
normally at the left side of the machine.

Evaluate the spread pattern.
Note: If you need to adjustment the spreading
pattern, refer to Adjusting the Spreader Pattern
(page 31).
6.
Note: Use the narrow-spreader distribution
flow-rate knob to control the discharge rate
of the granular material from the hopper onto
the impeller when the narrow-distribution
impeller-gate lever is in the OPEN position.
When you are finished spreading, close the
wide-distribution impeller-gate lever.
Note: Only the wide-distribution impeller-gate
lever closes the impeller gate. Pushing the
wide-distribution impeller-gate lever forward also
resets the narrow-distribution impeller-gate lever
to the forward position.
7.
Clean the hopper after each spreading session;
refer to Cleaning and Lubricating the Spreader
(page 44).
Important: Always empty and clean the
spreader immediately after each use. Failure
to do so may cause the chemicals to corrode
the spreader and other components.
33
Spreading Tips
Important: Ensure that you calibrate the spreader
before you start using it.

• To ensure uniform application, broadcast the
material in an overlapping pattern as shown in
Figure 37.
Note: The highest amount of material will
dispense from the front of the hopper and less
material from each side. You can adjust the
distribution pattern to achieve the desired results.
• Watch for changes in the distribution pattern;
unequal distribution may lead to striping.

Operating the Sprayer
1.
CAUTION
Measure and visibly mark a course length used
to calculate the average ground speed. Record
.
the course length here:
Note: In this example the course length is 45.7
m (150 ft).
Chemicals are hazardous and can cause
personal injury.
• Read the chemical manufacture’s
directions on the label before handling
the chemicals; follow all manufacturer
recommendations and precautions.
• Keep chemicals away from your skin.
Should contact occur, wash the affected
area thoroughly with soap and clean water.
2.
Add clean water into the spray tank until it is 1/2
full; refer to Filling the Spray Tank (page 39).
3.
Drive the machine to an area far enough away
from the course so that when you are driving
it into the course, the machine travels at the
desired ground speed before reaching the first
marker.
4.
Use a stop watch to measure the time (in
seconds) that it takes the machine to travel the
marked course (45.7 m (150 ft) in this example)
while maintaining the desired ground speed.
Record your course time in the course time
worksheet.
• Wear eye protection, gloves, and any other
protective equipment recommended by the
chemical manufacturer.
Use the sprayer to disperse liquid herbicides,
pesticides, fertilizers, and other substances. Before
using the sprayer ensure that you have cleaned
the tank, plumbing, and nozzles before adding any
chemicals. When you use the sprayer, you first fill the
spray tank, then apply the chemical solution to the
work site, and then when you are finished spraying,
clean the tank. It is important to complete all 3 of
these steps to avoid damaging the sprayer. For
example, Do not mix and add chemicals in the spray
tank the night before and then spray in the morning.
This could lead to separation of the chemicals and
possible cause damage to components of the sprayer.

Using the Sprayer
g027391
Figure 41
Before Operating the Sprayer
Some chemicals are more aggressive than others
and each chemical interacts differently with various
materials. Some consistencies of sprayer chemicals
(e.g. wettable powders, charcoal) are more abrasive
and lead to higher-wear rates. If a chemical is
available in a formulation that would provide increased
life to the sprayer, use this alternative formulation.
Calibrate the sprayer before you start the spray
application; refer to Calibrating the Sprayer (page 35).

California Proposition 65 Warning Information
What is this warning?
You may see a product for sale that has a warning label like the following:
WARNING: Cancer and Reproductive Harm—www.p65Warnings.ca.gov.
What is Prop 65?
Prop 65 applies to any company operating in California, selling products in California, or manufacturing products that may be sold in or brought into
California. It mandates that the Governor of California maintain and publish a list of chemicals known to cause cancer, birth defects, and/or other
reproductive harm. The list, which is updated annually, includes hundreds of chemicals found in many everyday items. The purpose of Prop 65 is to
inform the public about exposure to these chemicals.
Prop 65 does not ban the sale of products containing these chemicals but instead requires warnings on any product, product packaging, or literature with
the product. Moreover, a Prop 65 warning does not mean that a product is in violation of any product safety standards or requirements. In fact, the
California government has clarified that a Prop 65 warning “is not the same as a regulatory decision that a product is ‘safe’ or ‘unsafe.’” Many of these
chemicals have been used in everyday products for years without documented harm. For more information, go to https://oag.ca.gov/prop65/faqs-view-all.
A Prop 65 warning means that a company has either (1) evaluated the exposure and has concluded that it exceeds the “no significant risk level”; or (2)
has chosen to provide a warning based on its understanding about the presence of a listed chemical without attempting to evaluate the exposure.
Does this law apply everywhere?
Prop 65 warnings are required under California law only. These warnings are seen throughout California in a wide range of settings, including but not
limited to restaurants, grocery stores, hotels, schools, and hospitals, and on a wide variety of products. Additionally, some online and mail order
retailers provide Prop 65 warnings on their websites or in catalogs.
How do the California warnings compare to federal limits?
Prop 65 standards are often more stringent than federal and international standards. There are various substances that require a Prop 65 warning
at levels that are far lower than federal action limits. For example, the Prop 65 standard for warnings for lead is 0.5 μg/day, which is well below
the federal and international standards.
Why don’t all similar products carry the warning?
•
•
Products sold in California require Prop 65 labelling while similar products sold elsewhere do not.
•
•
The enforcement of Prop 65 is inconsistent.
A company involved in a Prop 65 lawsuit reaching a settlement may be required to use Prop 65 warnings for its products, but other companies
making similar products may have no such requirement.
Companies may elect not to provide warnings because they conclude that they are not required to do so under Prop 65; a lack of warnings for a
product does not mean that the product is free of listed chemicals at similar levels.
Why does Toro include this warning?
Toro has chosen to provide consumers with as much information as possible so that they can make informed decisions about the products they buy and
use. Toro provides warnings in certain cases based on its knowledge of the presence of one or more listed chemicals without evaluating the level of
exposure, as not all the listed chemicals provide exposure limit requirements. While the exposure from Toro products may be negligible or well within the
“no significant risk” range, out of an abundance of caution, Toro has elected to provide the Prop 65 warnings. Moreover, if Toro does not provide these
warnings, it could be sued by the State of California or by private parties seeking to enforce Prop 65 and subject to substantial penalties.
