Remember that your machine is factory set to put down 1/3 gallon of liquid per 1,000 sq. ft ( at 5MPH and
40PSI ). For instance, some products call for 1.1 to 1.5 oz per 1,000 sq. ft. We would recommend using 1.3

amount by the number of gallons put in the tank.

*Calibrated at 5 MPH
Accuway balances the spread pattern, by shifting the product placement on the spinner. Placing the product on the
impeller close to the shaft or the center will cause the spread pattern to be heavier to the right as it rides the impeller
for a longer period. If the product is placed on the outer edge of the impeller, the spread pattern will be heavier to the
left ( because the spinner is turning clockwise ).
1) Start with the Accuway control cable all the way forward or in ( this is home base ).
2) Begin to spread the product. As you are spreading you should be able to see the spread pattern in front of you.
Generally, all spreaders will tend to throw fertilizer heavy to the right. As you continue to spread, pull the Accuway
control towards you very slowly ( small increments ) until you begin to bring the spread pattern directly centered
in front of you.
3) Once you have the spread pattern centered, lock the Accuway cable in place. There should be no reason to reset
the Accuway for that product unless you see that the spread pattern has changed due to bumping the lever. If it has
changed slightly, simply re-adjust the pattern while you’re spreading.

Fuel Safety
• Gasoline is harmful or fatal if swallowed.
Long-term exposure to vapors has caused cancer
in laboratory animals. Failure to use caution may
cause serious injury or illness.
Use extreme care when handling fuel.
In certain conditions gasoline is extremely flammable
and its vapors are explosive. A fire or explosion from
gasoline can burn you, others, and cause property
damage.
• Fill the fuel tank outdoors on level ground, in an
open area, when the engine is cold. Wipe up any
gasoline that spills.
• Never refill the fuel tank or drain the machine
indoors or inside an enclosed trailer.
• Do not fill the fuel tank completely full. Fill the fuel
tank to the bottom of the filler neck. The empty
space in the tank allows the gasoline to expand.
• Never smoke when handling gasoline, and stay
away from an open flame or where gasoline fumes
may be ignited by a spark.
• Store gasoline in an approved container and keep
it out of the reach of children.
• Add fuel before starting the engine. Never remove
the cap of the fuel tank or add fuel when engine is
running or when the engine is hot.
• If you spill fuel, do not attempt to start the engine.
Move away from the area of the spill and avoid
creating any source of ignition until the fuel vapors
have dissipated.
• Do not operate the machine without the entire
exhaust system in place and in proper working
condition.
• In certain conditions during fueling, static electricity
can be released, causing a spark, which can ignite
gasoline vapors. A fire or explosion from gasoline
can burn you and others and cause property
damage.
– Always place gasoline containers on the
ground away from your vehicle before filling.
– Do not fill gasoline containers inside a vehicle
or on a truck or trailer bed, because interior
carpets or plastic truck bed liners may insulate
the container and slow the loss of any static
charge.
– When practical, remove gasoline-powered
equipment from the truck or trailer and refuel
the equipment with its wheels on the ground.
– If this is not possible, then refuel such
equipment on a truck or trailer from a portable
container rather than from a gasoline-dispenser
nozzle.
– If you must use a gasoline-dispenser nozzle,
keep the nozzle in contact with the rim of the
fuel tank or container opening at all times
until fueling is complete. Do not use a nozzle
lock-open device.
– Avoid prolonged breathing of vapors.
– Keep your face away from the nozzle and
gasoline tank or container opening.
– Keep gasoline away from your eyes and skin.
– Never siphon gasoline by mouth.
• To help prevent fires, do the following:
– Keep the engine and the engine area free
from accumulation of grass, leaves, excessive
grease or oil, and other debris that can
accumulate in these areas.
– Clean up oil and fuel spills and remove
fuel-soaked debris.
– Allow the machine to cool before storing the
machine in any enclosure. Do not store the
machine near a flame or any enclosed area
where open pilot lights or heat appliances are
present.

• Do not add oil to gasoline.
General Safety
Using
Stabilizer/Conditioner
Use your full attention when operating the machine.
Do not engage in any activity that causes distractions;
otherwise, injury or property damage may occur.
• Running the engine will cause engine parts,
especially the muffler, to become extremely hot.
Severe burns can occur on contact, and debris,
such as leaves, grass, and brush, can catch fire.
– Allow engine parts, especially the muffler, to
cool before touching them.
– Remove accumulated debris from the muffler
and engine area.
• Engine exhaust contains carbon monoxide, which
is an odorless, deadly poison that can kill you. Do
not run the engine indoors or in a small, confined
area where carbon monoxide fumes can collect.
• Chemicals are hazardous and can cause personal
injury.
– Read the directions on the chemical labels
before handling the chemicals and 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.
– Wear goggles, gloves, and any other protective
equipment recommended by the chemical
manufacturer.
– The owner/user can prevent and is responsible
for accidents that may cause personal injury or
property damage.
– This machine was designed for 1 operator only.

grass or other objects that may hide obstacles
or obscure vision. Uneven terrain could
Use a fuel stabilizer/conditioner in the machine to
provide the following benefits:
Important: Do not use fuel additives containing
methanol or ethanol.
Add the correct amount of fuel stabilizer/conditioner
to the gasoline.
Note: A fuel stabilizer/conditioner is most effective
when mixed with fresh gasoline. To minimize the
chance of varnish deposits in the fuel system, always
use fuel stabilizer.

discharging material against a wall or obstruction
as the material may ricochet back toward you.
Be alert, slow down, and use caution when making
turns. Look behind you and to the side before
changing directions. Do not spread or spray in
reverse unless it is absolutely necessary.
Stop spreading or spraying while making tight
turns to minimize uneven distribution pattern,
application rate, and chemical drift.
Chemicals may drift and cause injury to people
and animals; it may also damage plants, soil, or
other property.
Do not change the engine governor setting or
overspeed the engine.
Ensure that all drives are in neutral and engage
the parking brake before starting the engine.
Park the machine on level ground. Shut off the
engine, wait for all moving parts to stop, remove
key, and engage the parking brake before doing

21
– Be alert and shut off the machine if children
enter the area.
– Before and while backing or changing direction,
look behind you, down, and side-to-side for
small children.
– Never allow children to operate the machine.
– Do not carry children, even if the machine is not
in use. Children could fall off and be seriously
injured or interfere with the safe operation of
the machine. Children wanting a ride could
appear in the working area without warning and
be run over or backed over by the machine.
Reduce the weight of the load when operating the
machine on hills and rough terrain to avoid tipping
or overturning of the machine.
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.
When operating with a heavy load, reduce your
speed and allow for sufficient stopping distance.
Reduce the speed and load while operating the
machine on rough terrain, uneven ground, and
near curbs, holes, and other sudden changes in
terrain. Loads may shift, causing the sprayer to
become unstable.
Sudden changes in terrain may cause abrupt
steering wheel movement, possibly resulting in
hand and arm injuries. Reduce the speed when
operating on rough terrain or near curbs.
Safely relieve liquid from the spray wand every
time you shut off the engine.
The spray wand traps liquids under high pressure,
even when engine is not running. High-pressure
spray discharge could cause serious injury or
death.
– Keep clear of the nozzle and do not direct
spray or stream at people, pets, or non-work
area property.
– Do not direct the spray on or near electrical
power components or source.
– Do not repair the spray wand, hoses, seals,
nozzle, or other wand components; replace
them.
– 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 the spray wand if the trigger lock is
damaged or missing.
– Do not keep the spray wand in the locked-open
position after you complete the job.
– When draining or relieving the system, Do not
allow anyone to stand in front of the 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

Preparing the Test Site and Machine
Operator supplied equipment: 15 shallow collection
pans and 15 graduated measuring cylinders
Note: The most accurate method to measure
the distribution uses shallow collection pans and
graduated measuring cylinders. In the example below,
the 15 shallow collection pans approximately 30 cm
26
(12 inches) wide, 91 cm (36 inches) long, and 5 cm
(2 inches) tall.
1.
Place one pan in the center of the drive path.
Arrange the next two pans, one on each side,
far enough apart to allow adequate room for the
drive tires of the machine to pass around the
center pan.
2.
Place the remaining pans in a straight line as
shown in Figure 20 or Figure 21.
• For larger granule materials:
Space 6 additional pans, on each side, 12
inches (30 cm) apart (Figure 20).

Example
One at a time, take a collection pan and dump
the contents into the corresponding graduated
cylinder. Record the amount of granular material
collected and return the pan to its location.
Repeat this until all pan contents have been
emptied.
2.
Note: Repeat broadcasting over the test site
several times, moving in the same direction
each time, until enough material is dispensed to
the collection pan to half fill a graduated cylinder.
8.
Go to the two corresponding pans. Starting from
the outer edge, measure the distance between

mark of the course.
Calculating the Application Rate
With the graduated measuring cylinder in the
same straight line as the pans, evaluate the
volume of material in each cylinder to determine
the quality of the distribution from the spreader.
1.
Determine the area and amount of material that
you are applying to the job site and record those
amounts in the area and materials worksheet.
To adjust the spreader pattern, refer to the
Adjusting the Spreader Pattern (page 31).
Record the job site area here:
.
Fill the hopper half-full of the desired material
and repeat steps 1 through 9 until you achieve
a uniform pattern.
Record the amount of job site material here:
.
Initially, use the recommended application rate
indicated in the Spreading Charts (page 30)
section or use the rate recommended listed on
the product manufacturer’s label as a guide to
help determine the amount of material that you
would spread over a 93 m2 (1,000 ft2) area.
2.
Determining the Effective Spreading Width
Use the effective width to determine the uniform
distribution of the granular material.
Note: The spreading width range is 1 to 8 m (3 to
25 ft).
1.
After the spreader pattern is correctly adjusted,
evaluate the amount of material in the center
graduated measuring cylinder.
2.
Locate the 2 graduated cylinder, one each
side of center, that contains 1/2 the measured
amount of the material that you observed in the
center graduated cylinder.
3.
4.
Note: In this example the calibration course is
1.8 m (6 ft) by 51m (167 ft).
Set the appropriate drop-rate cam setting; refer
to the Spreading Charts (page 30) as a starting
point.
Add material to the hopper.
Note: In this example we added 11.3 kg (25
lb) of material.

5.
Drive the spreader over the calibration course
while applying the material.
6.
Empty the remaining material of the hopper into
a clean bucket.
7.
Weigh the bucket containing the material and
record the weight. Pour the contents back
into the hopper and then weigh the empty
bucket. Calculate the remaining material weight
using the remaining material weight formula.

If necessary, adjust the drop-rate cam to achieve
the recommended application rate. Once you
achieve the correct application rate, repeat
this procedure an additional time to verify your
results.
Remove the cover from the hopper, add the
material that you are spreading, and install the
cover onto the hopper (Figure 23).
Note: Do not overload the hopper; the
maximum weight capacity of the hopper is 54
kg (120 lb).
Note: You may place extra bags of granular
material in the cargo boxes behind the spray
tanks.
Important: Designate a new calibration
course each time, so that the turf is not
damaged by excessive application of
material.

Operating the Sprayer
CAUTION
Chemicals are hazardous and can cause
personal injury.
• Read the chemical manufacturer’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.
• Wear eye protection, gloves, and any other
protective equipment recommended by the
chemical manufacturer.
g312557
Figure 29
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.
1. Effective broadcast width—variable 0.9 to 7.6 m (3 to 25 ft)
5.
Evaluate the spread pattern.
Note: If you need to adjustment the spreading
pattern, refer to Adjusting the Impeller-Speed
Control (page 25), Calibrating the Spreader
(page 26), and Adjusting the Spreader Pattern
(page 31).
6.
When you are finished spreading, close the
hopper-door control.
7.
Clean the hopper after each spreading session;
refer to Cleaning and Lubricating the Spreader
(page 41).
Important: When you use your sprayer,
thoroughly clean it at the end of the day.
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.
Spreading Tips
Important: Ensure that you calibrate the spreader
before you start using it.
• To ensure uniform application, broadcast pellet or
granular material in an overlapping pattern.
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.

Sprayer Nozzle Application Rate
The machine is factory equipped with lavender
colored nozzle tips that have an application rate of
1.3 L (0.34 US gallon) per 93 m2 (1,000 ft2) when the
sprayer pressure is 2.8 bar (40 psi), and the machine
is driven 8 kph (5 mph).
• Turn the knob of the throttle valve clockwise to
increase spray-system pressure (Figure 40).
• Use to the nozzle application rate chart that follows
when selecting nozzles and spraying with the
machine.
• Refer to the spreader/sprayer chart affixed to
the back of the knee pad for quick reference
calibration information in the field.
• Your machine supports application rates between
0.95 L per 93 m2 (0.25 US gallon per 1,000 ft2)
through 3.8 L per 93 m2 (1.0 US gallon per 1,000
ft2).

Calculating the Amount of Product for a
Solution of Chemical
1.
Multiply the average product application rate by
the 1-gallon nozzle tip factor to determine the
1-gallon application rate.
Example: median application rate value—38
ml/93 m2 (1.3 fl oz per 1,000 ft2) of 1.1 to 1.5) x
3 (lavender nozzle tip—nozzle tip factor) = 3.9
(adjusted application rate)
g311520
2.
Figure 40
1. Locknut
2. Throttle valve knob
Multiply the 1-gallon application rate by the
amount of chemical solution that you need to
add to the spray tank.
Example: 3.9 (adjusted application rate) x
gallons needed. If you are preparing a 114 L (30
US gallon) solution of chemical, use 3.5 L (117 fl
oz) of product (3.9 x 30) for 114 L (30 US gallon)
of water.
• Turn the knob of the throttle valve counterclockwise
to decrease spray-system pressure (Figure 40).
Sprayer-system pressure displays on the pressure
gauge (Figure 41). When the spray nozzles are open,
sprayer-system pressure decreases slightly; adjust
throttle valve to compensate for the drop in pressure.

Using the Sprayer
6.
Add 3/4 of the required water to the sprayer tank
through the filler neck.
Before Operating the Sprayer
Important: Always use fresh, clean water
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.
in the spray tank. Do not pour chemical
concentrate into an empty tank.
Calibrate the sprayer before you start the spray
application; refer to Sprayer Nozzle Application Rate
(page 36).

Filling the Tank
Important: Ensure that the chemicals that you
are using in the sprayer are compatible for use
with O-rings and seals made from fluoroelastomer
material (refer to the chemical manufacturer's
label; it should indicate if it is not compatible). If
you use a chemical that is not compatible with
fluoroelastomer material, the O-rings and seals in
the sprayer can degrade and leak.

engage parking brake, and pull the wire(s) off the
spark plug(s) before you do any maintenance.
Also, push the wire(s) aside so that it does not
accidentally contact the spark plug(s).
The engine can become very hot. Touching a hot
engine can cause severe burns. Allow the engine
to cool completely before servicing or repairing
around the engine area.
Park the machine on level ground and allow it to
cool. Never allow untrained personnel to service
the machine.
Disengage the spray or close the spreader gate,
set the parking brake, shut off the engine, and
remove the key or disconnect the spark-plug wire.
Wait for all movement to stop before adjusting,
cleaning, or repairing the machine.
Disconnect the battery or remove the spark-plug
wire before making any repairs. Disconnect the
negative terminal first and the positive terminal
last. Connect positive terminal first and negative
terminal last.
Relieve the pressure from the spray system before
servicing the machine.
Empty the tank and/or hopper before tilting the
machine for maintenance and before storage.
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; otherwise, gangrene may result.
– If equipped, ensure that all hydraulic fluid
hoses and lines are in good condition and
that all hydraulic connections and fittings are
tight before applying pressure to the hydraulic
system.
– Keep your body and hands away from pinhole
leaks or nozzles that eject high-pressure
hydraulic fluid.
– Use cardboard or paper, not your hands, to
find hydraulic leaks.
– Safely relieve all pressure in the hydraulic
system by placing the motion-control levers
in neutral and shutting off the engine before
working on the hydraulic system.
Raising the machine for service or maintenance
relying solely on mechanical or hydraulic jacks
• Carefully release the pressure from components
with stored energy.
• Keep your hands and feet away from moving
parts. If possible, do not make adjustments while
the engine is running. If the maintenance or
adjustment procedure requires the engine to be
running and components moving, use extreme
caution.
• Contact with moving parts or hot surfaces may
cause personal injury. Keep your fingers, hands,
and clothing clear of rotating components and hot
surfaces.
• Check all bolts frequently to maintain their proper
tightness.

Troubleshooting
Important: Ensure that the operator safety mechanisms for the machine are connected and in proper
operating condition before you use the machine.
When a problem occurs, do not overlook the simple causes. For example, starting problems could be caused
by an empty fuel tank.
The following table lists some of the common causes of trouble. Do not attempt to service or replace major
engine items or any items that call for special timing of adjustments procedures (such as valves, governor, etc.).
Have this work done by your engine service dealer.
Note: When disconnecting electrical connectors, do not pull on the wires to separate the connectors.
The Charging System
20 Amp Regulated Alternator
The regulated alternator system provides AC current through two output leads to the regulator-rectifier (Figure
105). The regulator-rectifier converts the AC current to DC, and regulates current to the battery. The charging
rate will vary with engine RPM and temperature.
Note: Stator, regulator/rectifier, and fly-wheel are not interchangeable with other charging systems.
