WARNING
FAILURE TO FOLLOW SAFE OPERATING PRACTICES MAY RESULT
IN SERIOUS INJURY OR DEATH.
•
Read this manual completely as well as other manuals that came with your sprayer/
spreader.
•
DO NOT operate on steep slopes. To check a slope, attempt to back up it. If the
machine can back up the slope without the wheels slipping, reduce speed and use
extreme caution.
•
Under no circumstances should the machine be operated on slopes greater than 15
degrees. ALWAYS FOLLOW OSHA APPROVED OPERATION.
•
Weight in the storage tanks and hopper will transfer when on a slope, this may
cause a loss of traction or increased risk of a roll-over.
•
When operating with a heavy load, reduce speed and allow sufficient braking
distance. Use extra caution on slopes.
•
Liquid loads shift during operation, especially while turning, going up or down
slopes, sudden changes in speed or while driving over rough surfaces. Shifting
loads can cause the machine to tip over.
•
Stay two spray widths away from slopes, drop offs, ditches, and retaining walls.
•
DO NOT operate on wet grass. Wet grass reduces traction and steering control.
•
Keep all shields in place.
•
Before performing any maintenance or service, stop the machine, remove the spark
plug wire(s), and remove the ignition key.
•
If a mechanism becomes clogged, stop the engine before cleaning.
•
Keep hands, feet, and clothing away from power-driven parts.
•
Keep others off the machine (only one person at a time).
REMEMBER - YOUR SPRAYER/SPREADER IS ONLY AS SAFE AS THE
OPERATOR!

4.13 HILLSIDE OPERATION
WARNING
DO NOT operate on steep slopes. Under no
circumstances should the machine be operated
on slopes greater than 15 degrees. See Figure 2-1,
Page 6 to determine approximate slope of area to
be sprayed. ALWAYS FOLLOW OSHA APPROVED
OPERATION.
1.
2.
8.
When operating with a heavy load, reduce speed
and allow sufficient braking distance. Use extra
caution on slopes.
9.
Liquid loads shift during operation, especially while
turning, going up or down slopes, sudden changes in
speed or while driving over rough surfaces. Shifting
loads can cause the machine to tip over.
10. Be aware that operating the machine on wet
surfaces, across slopes or down hill may cause the
machine to lose traction. Loss of traction to the drive
wheels may result in sliding and loss of steering and
braking.
This machine has been designed for good traction
and stability under normal spraying/spreading
conditions. However, caution must be used when
traveling on slopes, especially when the grass is wet.
Wet grass reduces traction and steering control.
11. Do not operate the machine when you are uncertain
about the traction, steering, or stability.
Stay two machine widths away from slopes, dropoffs, ditches, and retaining walls. See Figure 4-21.
14. Do not suddenly apply the brakes.
12. Never back down a hill.
13. Keep tires properly inflated.
15. Make sure to lean to properly transfer your weight
while driving on a slope. See Figure 4-22.
Figure 4-21. Distance From Hazard
3.
Operate the machine across slopes, avoid going up
and down slopes.
4.
To prevent tipping or loss of control, do not start or
stop suddenly, avoid unnecessary turns and travel at
reduced speed. If tires lose traction, disengage the
sprayer/spreader and proceed slowly off the slope.
5.
Avoid sudden starts when spraying/spreading
uphill. Sudden starts may cause the machine to tip
backwards.
6.
Loss of traction may occur when traveling down hill.
Weight transfers to the front of the machine and
may cause the drive wheels to slip causing loss of
braking or steering.
7.
Weight in the storage tanks and hopper will transfer
when on a slope, this may cause a loss of traction or
increased risk of a roll-over.

4.21 RECOMMENDATIONS FOR
SPREADING AND SPRAYING AT THE SAME
TIME
4.19 RECOMMENDATIONS FOR SPRAYING
WITH THE SPRAY WAND
1.
Before spreading/spraying make sure the area is
clear of objects that may be contaminated with
chemicals and ingested or used after (Ex. dogbones or children's toys).
2.
When spreading and spraying at the same time,
the spreader will need to be calibrated to spread
material at twice the spraying width. This will assure
proper overlap and application rates for both
systems. (Ex. If you're spraying with a 6ft spray
width, your effective spread width will need to be
12ft.) Refer to Section 6-7 and 6-8 for calibration
procedures.
3.
The spreader should spread back to the center
of the tire marks from your previous pass and the
spray boom tip should be about 20" away from the
previous boom pass.
4.
During calibration, the speed (mph) should be
determined while doing the sprayer calibration. Make
sure to use the same speed while calibrating the
spreader.
5.
Make sure both the sprayer and the spreader are
properly calibrated for the material to be spread and
sprayed.
WARNING
The spray wand traps liquid under high pressure,
even when the engine is off. H igh pressure
discharge could cause serious injury or death.
1.
Keep clear of the nozzle and do not direct the spray
wand at people, pets or non-work area.
2.
Do not direct the spray towards or near electrical
power sources or components.
3.
Do not attach hoses or other components at the end
of the spray wand.
4.
Do not attempt to disconnect the spray wand from
the machine while the sprayer system is pressurized.
5.
Lock the spray wand to the OFF position when the
job is complete.
6.
Do not repair the spray wand, hoses, seals, nozzle,
or other wand components, Always replace them.

Section 5
R
5.
WARNING
Do not operate the machine without the operator
cushion installed.
When calibrating the sprayer system the operator will
need to know the speed of the machine, the amount
of product coming out of the nozzles, and the effective
spray width being used.
- NOTE The spray calibration work sheet on page 37 can
be used to work through the calibration process
and stored for future reference.

6.
You should set the sprayer up to reach the desired
application rate. Refer to the spray guide chart in
Section 5-11 for a base setting (the spray guide chart
should only be used as a base setting, MANUAL
calibration is always best).
7.
The first thing to calculate would be the machine speed
(mph). This can be done using the machines display, or
manually, using steps 8-11. Manual calculation should
be done periodically to make sure the display reads
accurately.
8.
To calculate this you will need to establish a test course
length (ft). The test course should be a straight open
and level area free of obstructions. The longer the
course the more accurate it will be.
- NOTE The course speed may vary from asphalt to turf.
It is recommended to use a turf course for speed
calibration.

5.7 CALIBRATING THE SPRAYER
1.
The sprayer system will need to be calibrated at the
beginning of each season, when the application rate
changes, and multiple times during the season (to
accomodate for wear depending on the chemicals
used, some chemicals are harder on nozzles than
others).
2.
Make sure the sprayer is properly calibrated for the
desired application rate. Different chemicals may have
different application rates, the machine will need to be
re-calibrated for each chemical(refer to the chemical
manufacturer's directions for application rate).
3.
To calibrate the sprayer, first, make sure the sprayer
system is clean and free from build up.
4.
9.
Drive this course with the machine at a spraying speed
throughout the entire distance of the course, record
the amount of time it takes. Repeat this process three
times.
10. Take the average time to travel the distance (add up
the three times and divide by 3 to get the average)
11. To calculate the ground speed, use the formula in
Figure 5-4. Make sure this number is the same as the
displayed mph on the machine's display.
Figure 5-4. Ground Speed Formula
The sprayer should always be calibrated with the tank
half full (to simulate average load weight) of clean
water.
31
Section 5
R
12. The next step is to calculate the effective spray width.
To calculate the effective spray width, take the number
of nozzles you are going to be using (3 nozzles on
the center boom and 1 on each end boom, 5 total)
and multiply it by 20.
16. Once you have the average flow (fl oz) for each nozzle,
add all the nozzle average (fl oz) results together. It will
then need to be converted to gallons (fl oz divided by
128). A flow rate in gallons per minute will then need
to be calculated. Follow the formula in Figure 5-6
13. The next step is to determine the output of the nozzles
on the sprayer. (Make sure the spray pressure is
set correctly, refer to the spray guide chart for the
recommended base pressure settings). To calculate
nozzle output, gather liquid (fl oz) from each nozzle
for the average amount of time it took to drive
the test course (number determined in step 10).
Measure (fl oz) each nozzle three times. Take these
measurements and calculate the average for each
nozzle (add the three test results for each individual
nozzle together and divide by 3 to get its average, do
this for each nozzle).
Figure 5-6. Gallons Per Minute Formula
17. Application rate will then need to be calculated by
using one of the formulas below. For gallons per acre
see Figure 5-7. For gallons per 1000ft² see Figure 5-8.
Figure 5-7. Gallons Per Acre
14. To check for nozzle wear, take all of the nozzle
averages and add them together, then divide by the
number of nozzles. This will give you the average
across the boom. If any one nozzle average is more
than 5% +/- from the boom average it will need to be
replaced or cleaned. (if the nozzle is less than the
average, it likely needs to be cleaned. If it is more
than the average, it likely is worn and needs to be
replaced.)
Figure 5-8. Gallons Per 1000ft²
18. These formulas will give you the gallons per acre or
1000ft² that your machine is applying. If this number
does not match the application rate you need, the
nozzles may need to be replaced or a pressure
adjustment may be needed. A different nozzle size
may also be needed if these numbers are off by a
large margin.
15. To calculate the amount (fl oz) that should be gathered
during the test period according to the desired GPA,
speed, and effective spray width being used. Use
the formula in Figure 5-5 to determine the amount
that should be coming out each nozzle during the
test period in fl oz. If the amount determined in step
13 is more than 5% +/- off of the amount determined
using the formula in Figure 5-5, the pressure, speed,
or nozzles may need to be adjusted or changed to
reach the desired results.

5.8 CALIBRATING THE SPREADER
1.
Make sure the spreader is properly calibrated for the
desired application rate. Each granular material will
spread differently dependant on size, temperature, and
moisture. The machine will need to be re-calibrated
for each material(refer to the chemical manufacturer's
directions for application rate).
2.
To calibrate the spreader, first make sure the spreader
system is clean and free from build up.
3.
The first step is determining the spreaders effective
spread width.
Figure 5-5. Required Fl Oz To Be Gathered
- NOTE If all measured nozzles produce the correct
amount according to the formula in Figure 5-5,
the sprayer should be properly calibrated (within
5% +/-) for the desired GPA you were aiming for.
Skip the remaining steps.
32
Section 5
R
4.
Establish a test area (make sure this area is an area
that you wouldn't mind having streaking or burning from
the fertilizer, OR use a paved surface and collect all of
the material after, to avoid possibility of turf damage
from run off ).
5.
Adjust the granular drop rate cam to the desired
application rate. Refer to the Spreader Chart in Section
5-10 (this is a starting point).
6.
To determine the effective spread width for large
granular items you will need 15 small pans (1ft², 1 or
2 inches high). Arrange 7 pans to the right (about 1
foot apart), 7 pans to the left (about 1 foot apart), and
1 pan in the center. Make sure to allow room for the
machine to drive between the 7 left pans and 7 right
pans with the center pan placed so it will miss the drive
tires and go underneath the machine during the pass.
See Figure 5-9
Figure 5-10. Small Granular Material
7.
Each pan's material should then be measured and
recorded. The effective spread width is determined by
taking these measurements and finding which pan on
each side has half of what the center pan has. (EX. If
the center pan has 16 ounces, and the 6th pan away
from the machine on each side has 8 ounces. The
effective spread width would be the distance between
the outside of the pan with 8 ounces on the left to the
outside of the pan with 8 ounces on the right.) See
Figure 5-11. If the path is not equal on each side, adjust
the diffuser control, and repeat the procedure until the
spread pattern is even on each side.
Figure 5-9. Large Granular Material
- NOTE Give the machine plenty of room to make the pass.
Operate the machine at "application" speed while
making the pass. Activate the spreader with ample
time to create a consistant path before getting to
the pans.
Figure 5-11. Measuring Effective Spread Width
Example
- NOTE For less accurate spread width, the pattern can
be aligned by using a cone on each side of the
spreader, adjust the pattern so the material barely
hits both cones with both cones equal distance
from the spreader. Measure the distance between
the two cones.
To determine the effective spread width for small granular
items you will need 27 small pans (1ft², 1 or 2 inches high).
Arrange 13 pans to the right (no gap), 13 pans to the left
(no gap), and 1 pan in the center. Make sure to allow room
for the machine to drive between the 13 pans on the left
and the 13 pans on the right, with the center pan placed so
it will miss the drive tires and go underneath the machine
during the pass. See Figure 5-10
8.
- NOTE Give the machine plenty of room to make the pass.
Operate the machine at "application" speed while
making the pass. Activate the spreader with ample
time to create a consistant path before getting to
the pans.
33
The next step is to establish the desired application
rate. Refer to the chemical manufacturer's
recommendations for application rate (lbs/1000 ft²).
Section 5

Useful Conversions
Once you have a desired application rate, mark a
test path of 50 or 100 feet (a shorter test course can
be used, but may be less accurate). Make sure the
machine operates at a spreading speed. Drive the
test path and record the number of seconds it takes
to do the path. Repeat the test path three times and
calculate the average time it takes (add all three
times together and divide by 3 to get the average).

5.9 ADDING SPRAY MIXTURE
- NOTE Give the machine plenty of room to get to the test
path, the machine should be at a speed that you
would spread at while driving through the test path.
1.
Fill each tank 1/2 to 3/4 full with clean water, before
adding any chemical
2.
To determine the amount of chemical to add to each
sprayer tank when the application rate is given in
weight per acre, follow the formula in Figure 5-13
(If the entire tank is going to be filled after adding
the chemical, use the total tank volume (gal) for
determining the amount to add).
10. To determine the amount of material to be applied
during a test path pass use the formula in Figure
5-12.
Figure 5-12. Amount That Should Be Applied During
Test Path Formula
Figure 5-13. Amount To Add
11. Fill the spreader with the correct weight(lbs),
determined using the formula in Figure 5-12.
3.
12. Make sure the gate setting is still set to the
recommended base setting, refer to the chart in
Section 5.10. (this is a base setting and may need to
be adjusted based on speed, product, and moisture)
To determine the amount of chemical to add to the
sprayer tanks when the application rate is given in
pounds of active ingredient per acre, with a material
containing a percentage of active ingredient. Follow
the formula in Figure 5-14 (If the entire tank is going
to be filled after adding the chemical, use the total
tank volume (gal) for determining the amount to
add).
- NOTE Make sure the test area is an area that you wouldn't
mind having streaking or burning from the fertilizer,
OR use a paved surface and collect all of the
material after, to avoid possibility of turf damage
from run off.
Figure 5-14. Amount To Add Active Ingredient
4.
13. With the gate setting set and the spreader at
operating speed, open the hopper door and allow
the spreader to spread for the average test course
time (a drop cloth can be used to deflect and catch
the material for easier clean up). The hopper should
empty as time expires. If it does not empty, the gate
setting will need to be adjusted to increase the flow.
If it empties too early, the gate setting will need to be
adjusted to decrease the flow. Repeat until proper
calibration/gate setting is reached.
When adding more than one chemical, follow the
W.A.L.E.S acronym for adding chemicals.

perfomance and longevity from the spray system.
1.
Do not store product in the system, it may cause
build up in the hopper and components. It will also
reduce spreader performance and longevity.
When flushing the foamer system use an area in
compliance with local, state, and federal disposal
guidelines.
2.
To increase sprayer performance and longevity, the
spreader system should be cleaned daily. Refer to
section 6.12A.
3.
Check hopper and inpeller daily for cracks, wear, or
build up of granular material.
4.
Clogged hopper gate, granular build up or impeller
wear may result in distorted spread rates.
5.
Clean the machine every day it is in use.
To flush the system you will need to:
1.
2.
Empty the holding tank (make sure you empty/
neutralize any chemical mixture used according to
the chemical manufactor's instructions).
Fill the tank with clean water, run the system. Make
sure you cycle through both foamer heads(make
sure to dispose of the rinsate according to the
chemical manufactor's instructions, as well as, local,
state, and federal guidelines). Repeat this step using
clean water until the foamer system is thoroughly
flushed.
3.
The foamer system should be stored dry, with the
holding tank lid slightly ajar to allow for proper drying
and to reduce potential mildew buildup.
4.
If the machine is to be stored in a climate that may
reach freezing before the next use, the sprayer
system will need to be winterized (if liquid is allowed
to freeze in the system, serious damage can occur).
Refer to section 6.11D.
A. CLEANING THE SPREADER
-IMPORTANTDo not use brackish or reclaimed water to clean
the machine.
50
1.
Park the machine in a designated cleaning area with
a level surface.
2.
If installed, remove the cover and empty the hopper
of all remaining granular material.
3.
Rotate the granular drop rate cam to allow the
hopper gate to open to the maximum position. See
Figure 6-9
4.
Open the hopper gate.
Section 6
R
11. Inspect the spreader impeller for wear, damage, or
material build up. If needed, replace the impeller.
12. Check hopper bushing for leakage every 20 hrs.
Replace if necessary.
B. LUBRICATING THE SPREADER

SCREEN
Figure 6-10. Hopper Screen
6.
Remove any granular material from the bottom of the
hopper.
7.
Use clean water to spray the inside and outside of
the hopper and components.
Figure 6-11. Apply Lubricant
-NOTEDo not use a pressure washer to clean the
machine. The high pressure water can force
residual-corrosive materials into the sprayer /
spreader components.
8.
Do not spray water directly on the hopper motor.
9.
Clean the hopper and remove build up daily..
10. Check the agitator pin daily, if agitator pin is missing
or damaged material may clump.
51
2.
Allow the hopper to completely dry before using.
3.
Inspect the hopper control cables after libricating to
ensure proper function.

warranties including merchantability, fitness for a particular purpose, or otherwise, are disclaimed in their entirety after the expiration of
the appropriate two (2) years for commercial use, or ninety (90) day warranty period. Scag’s obligation under this warranty is strictly and
exclusively limited to the repair or replacement of defective parts and Scag does not assume or authorize anyone to assume for them
any other obligation. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply
to you.
Scag assumes no responsibility for incidental, consequential, or other damages including, but not limited to, expense for gasoline,
expense of delivering the sprayer/spreader to an Authorized Scag Service Dealer and expense of returning it to the owner, mechanic’s
travel time, telephone or communication charges, rental of a like product during the time warranty repairs are being performed, travel,
loss or damage to personal property, loss of revenue, loss of use of the machine, loss of time or inconvenience. Some states do not
allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you. This
warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
