FOREWORD
The MTD Pro line of sprayers is designed to provide professional turfgrass managers with reliable spray
equipment. The line includes both polyethylene and fiberglass tank sprayers. They are gasoline powered and
range in maximum output from 6.0 GPM to 14 GPM. This manual presents the operating and maintenance
instructions necessary to keep your MTD Pro Sprayer at peak efficiency. If properly operated and maintained,
your MTD Pro Sprayer will provide dependable service.
SAFETY PRECAUTIONS
A. General
1. No one should operate or maintain this
sprayer who has not read this manual.
2. Keep adults, children and pets away from the
sprayer and the area to be sprayed.
3. If truck or trailer mounted, make certain the
sprayer is securely bolted to the frame of the
truck or trailer.
4. When spraying pesticides:
a.ALWAYS FOLLOW THE DIRECTIONS ON
THE LABEL
b.Avoid breathing vapors.
c.Avoid contact with skin, eyes or clothing.
d.Wear rubber boots or rubberized shoes.
e.Wear work clothes with long-sleeved shirts
and long-legged pants.
f.Change to clean clothing daily.
g.Wash hands and face before eating or
smoking.
h.After spraying bathe thoroughly.
5. Wear a face shield and rubber gloves when
handling concentrates.
6. Do not remove any shields, guards or safety
devices from the sprayer. If a shield, guard or
safety device is damaged or does not function,
repair or replace it before operating the sprayer.
B. Related to Gasoline or Engines
1. GASOLINE IS HIGHLY FLAMMABLE
RESPECT IT!
2. Do not smoke or permit others to smoke while
handling gasoline.
3. Always use approved containers for gasoline.
4. Always shut off a gasoline engine and permit it
to cool before removing the cap of the fuel tank.
5. Always fill the fuel tank outdoors.
6. If the fuel container spout will not fit INSIDE the
fuel tank opening, use a funnel.
7. When filling the fuel tank, stop when the
gasoline reaches 1/2 inch from the top. This
space must be left for expansion. DO NOT
OVEFIFILL!
8. Wipe up any spilled gasoline.
9. To prevent hand or arm injury, always pull
engine starter cord rapidly to avoid kickback.
10. Never run a gasoline engine indoors without
adequate ventilation. Exhaust fumes are
deadly.
11.To avoid serious burns, do not touch a gasoline
engine, the exhaust pipe or muffler while the
engine is running or until it has cooled after it
has been shut off.
C. Related to Batteries
1. The electrolyte in a lead-acid battery is
dilute sulfuric acid which is a very
dangerous and corrosive liquid. Always
wear safety glasses or goggles and rubber
gloves when working on a lead-acid
battery.
2. Do not overfill a lead-acid battery when filling
the cells with distilled water.
3. Lead-acid batteries generate hydrogen and
oxygen gases which form an explosive
mixture. Keep sparks and flames away at all
times.

OPERATING INSTRUCTIONS
A.CONTROLS
1. Engine Choke
There are usually two moving levers on the side of
an engine near the carburetor. One of these is the
choke, the other is the throttle. The choke lever
should be moved all the way to the "CHOKE"
position when starting a cold engine. After the
engine starts, slowly move the lever all the way
back to the "RUN" position as the engine warms
up. A warm engine should not be choked.
2. Engine Throttle
The second moving lever on the side of an engine
near the carburetor is the throttle. For starting,
place the lever at 50% of the maximum RPM. For
pump pressures up to about 100 psi, the throttle
should be set at 30% of the maximum RPM. For
maximum pressures, the throttle should be set at
"FAST" or 100% of the maximum RPM.
3. Ignition Switch
NOTE: Make sure the pump is not under
pressure before trying to start the engine.
a. Recoil-Start Engines
On some engines, moving the throttle lever to
"OFF" or "STOP", while the engine is running
will short out the magneto and stop the
engine. On other engines, a separate lever or
knob on the side or top of the engine functions
as an ignition switch. They have two positions:
"OFF" and "START". They must be placed in
the "START" position before trying to start the
engine. Moving the lever or turning the knob
back to the "OFF" position while the engine is
running will short out the magneto and stop
the engine.
b. Electric-Start Engines
Automotive-type key switches are used as
ignition switches and are usually found on the
side or top of the engine. A clockwise 45° turn
closes the ignition circuit and turning the
switch further against spring pressure starts
the engine. The key should always be
removed from the switch if the sprayer is to be
left unattended.
4. Rewind Pull-Cord Starter
Located on the right side of the engine. To start
the engine, set the choke and the throttle and
grasp the starter grip and pull slowly until the
starter engages. Then pull the cord rapidly to
overcome compression, prevent kickback and start
the engine. Repeat if necessary with the choke
opened slightly. When the engine starts, slowly
open the choke all the way.
5. Valves
There are several ball valves used on the
sprayers. They serve as pump outlets and are
mounted under the pressure regulator. Ball valves
operate with a quarter turn movement of the
handle. When the handle lines up with the
direction of flow, the valve is open. When the
handle is at a 90° angle to the direction of flow, the
valve is closed. There is a gate valve in the suction
line at the front of the engine plate near the drain
fitting. The handle should be turned all the way
counterclockwise to open the valve and all the way
clockwise to close the valve. To drain the tank, the
cap must be removed from the drain fitting and the
gate valve must be opened.
6. Pressure Gauge
Mounted in the pressure regulator housing, the
pressure gauge indicates the pressure in the
output line to the spray gun, wand or boom and the
line to the hydraulic agitator, if used. The gauge is
graduated in pounds per square inch (psi) and
kilopascals (kPa).
7. Pressure Regulator
Located on the side of the pump opposite the drive
shaft. There are different styles of regulators, but
they all function in the same way. A spring-loaded
plunger rests against a valve seat which forces the
pump flow to the outlets. The springs are opposed
by the hydraulic pressure generated by the pump.
If this pressure exceeds the spring pressure, the
plunger is lifted off of its seat and part or all of the
flow goes to bypass. All of the pressure regulators
have operating levers which in one position,
remove the spring pressure from the plunger and
permit the pump's flow to dump to bypass and in
the other position, apply the spring pressure to the
plunger and force the pump's flow to the outlets.
One valve has a toggle-type operating lever with a
ball which can be hooked in different notches for
adjustment. Another regulator has a knob that
turns about 90° from "OFF" to "ON". Still another
has a hinged part of the plunger shaft work as the
operating lever. All of the regulators also have a
means for adjusting the operating pressure. This is
a threaded knob, a ring or a brass adjustment nut
which when threaded down toward the base of the
pressure regulator, increases the spring pressure.
Normally, the regulator should be set to provide
about 100 psi with both output ball valves closed.
Then the output ball valve to the application device
is opened completely and with bypass or
pressurized jet agitation, the output ball valve to
the agitator line is adjusted to provide the desired

flow rate and with the mechanical agitation, the
pressure regulator is adjusted to provide the
desired flow rate.

B.SET-UP
1. General
Check all the bolts on the sprayer for tightness.
Make certain all hose clamps are tight. Check that
the tank straps are tight on poly-tank sprayers.
Check that the pulleys and belts are tight and
aligned on fiberglass tank sprayers. (For pulley
and belt adjustment, see the Maintenance Section
on page 13.) Check that electrical connections are
sound on electric sprayers.
2. Installation In a Van or Pickup Truck
Once the sprayer is in the desired position in your
van or pickup truck, it should be securely bolted
through the truck bed to the vehicle's frame. Bolts
should be used at each corner of the sprayer's
frame and should be either cap screws placed
through the holes punched in the frame for this
purpose or large U-bolts or J-bolts over the
sprayer's steel frame and down through the truck
bed to the vehicle's frame. Bolts of at least 3/8"
diameter should be used for a 50 gallon sprayer,
1/2" diameter for a 100 gallon sprayer, 5/8"
diameter for a 200 gallon sprayer and 7/8" for a
300 gallon sprayer. Mounting hardware is not
supplied for the sprayer because the installation
will vary with each vehicle.
3. Wiring
The following instructions are for providing
electrical power to the electric hose reel if your
sprayer is so equipped. The vehicle's or sprayer's
battery should be a 12-Volt DC automotive-type.
THE VEHICLE CAN HAVE EITHER A POSITIVE
OR NEGATIVE GROUND SYSTEM AND
THEREFORE POLARITY IS NOT SHOWN ON
THE WIRING DIAGRAM.

Attach a 5/16" ring terminal to the wire and
connect it to the large solenoid terminal opposite
the one to which the reel motor lead is
connected.
f. Ground the frame of the sprayer to the vehicle
body as follows:
NOTE: If the sprayer has been properly bolted to
the frame of the vehicle with bolts passing through
or over the sprayer's frame and the vehicle's
frame, the sprayer Is grounded, this step may be
omitted.
1. Locate a vehicle body bolt near or under the
sprayer's frame that can be easily removed
and replaced.
2. Place a bolt through the nearest punched hole
in the sprayer's frame.
3. Cut the remaining #8 wire to the proper length
to reach between these two bolts. Strip
approximately one inch of insulation from each
end of the wire.
4. Remove the bolts or nuts and scratch off any
paint that would prevent making metal to metal
contact.
5. Wrap the stripped end of the wire around each
bolt and replace the bolts or nuts.
f. Reconnect the ground cable removed from the
battery in Step a.
g. Test the circuit by pulling some hose from the
reel and then pushing the reel switch located on
the reel mounting frame. The reel should
retrieve the hose. If your vehicle has a positive
ground system, the reel will run in reverse and
spill out hose. To make the reel rotate in the
proper direction, reverse the reel motor leads.
Take the motor lead that goes to the solenoid
and interchange it with the lead that is grounded
to the motor mounting.
C.SPRAYING
1. Starting the Sprayer (Gasoline-Powered)
a. Check the fuel supply and engine oil level.
b. Check the level of the oil in the pump. It should
be halfway up the sight tube.
c. Check the pressure in the pump's pulsation
damper. The pressure should be 10% of the
expected operating pressure.
d. Clean the in-line strainer if it is dirty.
e. Fill the tank one third full with clean water.
f. Make certain the gate valve in the suction line is
open and the outlet ball valves are closed.
g. Open the operating lever on the pump's
pressure regulator so there will be no load on
the pump when you start the engine.
h. Start the engine.
i. Run the pump at zero pressure for one minute to
remove any air from the system.
j. Close the operating lever on the pressure
regulator and adjust the pressure to about 100
psi for a flow rate of 1-1/2 to 3 gallons per
minute.
k. Open the ball valve in the hose to the application
device. Check the flow rate out of the application
device with a calibrated container.
(See Calibration.)
l. Adjust the flow rate by adjusting the ball valve in
the line to the agitator or by adjusting the
pressure regulator. When the flow rate is
correct, close the ball valve in the hose to the
application device and note the pressure setting.
You should be able to produce the same flow
rate at any time by returning the pressure to this
setting as long as no change has been made in
the hose or application device.
m.You are now ready to add the product to the
tank with the sprayer running under full agitation.
n. After the product is completely mixed, fill the
tank to the proper level with clean water.

OPERATING INSTRUCTIONS
Calibration
a.Hand Spraying
There are two keys to proper calibration of hand
spraying. One is knowing your spraying pace, that is,
the time it consistently takes you to spray an even
application of product on each 1000 sq. ft. area. The
other is always knowing the current flow rate out of
the application device on your sprayer.
The first step is to set up your sprayer to spray two
gallons per minute. This is a common flow rate that
can be used to check your spraying pace. You need
a graduated container. Fill the sprayer tank one third
full with clean water and start it up. Using the gun or
wand that is mounted on your sprayer, spray into the
graduated container for one minute. Check how
much water you collected. Adjust the flow rate by
adjusting the ball valve in the line to the agitator or
the pressure regulator if necessary, until you can
collect two gallons in one minute.
The next step is to determine how long it takes you
to evenly spray 1000 sq. ft. Measure an area 20 ft.
by 50 ft. on a paved surface. Spray the area evenly
with clean water. Use a stop watch to time your
application. After the water evaporates, spray the
area again.
Repeat this several times and average the
application times. Spraying on asphalt or concrete
will permit you to see the pattern you are applying
and will give you a better conception of even
application. Check the spray pattern as the water
evaporates. Spraying technique is just as important
as volume sprayed.
If your sprayer is set at a flow rate of two gallons per
minute and your spraying pace is .75 minutes per
1000 sq. ft., you are applying liquid at a rate of 1.5
gallons per 1000 sq. ft. which is your application
rate. (2 gallons/minute x .75 minutes/1000 sq. ft. =
1.5 gallons/1000 sq. ft.) - the application rate.)
It is essential to check the flow rate from the
application device on your sprayer every working
day. And to check your spraying pace and the
spraying pace of others who will use the sprayer
every month. The amount of liquid you apply
depends on the flow rate of your sprayer and your
spraying pace. You can check your spraying pace
on every lawn you spray if you have measured the
lawn accurately.
Your tank has gallonage markers which may also be
used to approximate the gallons of liquid that you
spray on each lawn. This figure should equal your
application rate times the number of 1000 sq. ft. in the
lawn.
Example: You have sprayed a 10,000 sq. ft. lawn at an
application rate of 1.5 gallons/1000 sq. ft. -- 10 x 1.5 =
15 gallons. A flow meter should read 15 gallons. When
you started there were 180 gallons of liquid in your
tank. Now there should be 165 gallons left in the tank.
Adding products to the tank:
CAUTION: AVOID ACCIDENTS. FOR
SAFETY, READ THE ENTIRE PRODUCT
LABEL INCLUDING PRECAUTIONARY
STATEMENTS. USE ALL PRODUCTS
ONLY AS DIRECTED.
The product label will tell you how much product
should be used per 1000 sq. ft. If the label says you
are to use 1.4 ounces per 1000 sq. ft. you divide the
number of gallons of water in the tank by your
application rate (gallons per 1000 sq. ft.) and multiply
by the number of ounces of product per 1000 sq. ft.
Example: 200 gallons divided by 1.5 gallons / 1000
sq. ft. times 1.4 ounces / 1000 sq. ft. 186.6 ounces =
11.6 pints.
You would fill the sprayer tank one third full with clean
water and then add 11.6 pints of product to the tank
through the strainer basket while the sprayer is
running under full agitation. After the product is
completely mixed, you would fill the tank to the proper
level with clean water.
b.Boom Spraying
There are two keys to proper calibration of boom
spraying. The first is knowing and controlling the
sprayers speed over the ground and the second is
always knowing the flow rate of the spray tips on the
boom. The following is a simplified procedure:
Measure and mark off a distance of 205 feet in an
area that best represents the average topography for
the area to be sprayed. Select a safe tractor (truckster)
speed (usually three to six MPH) which can be
maintained while spraying. Write down the engine's
RPM and the gear selection so that this speed can be
maintained during both calibration and actual spraying.
With the tractor (truckster) traveling at the selected
speed and with the sprayer one half full of water, time
and record the seconds taken to travel the 205 feet.
With the sprayer still half full of water, start the
sprayer's engine and adjust the pump's pressure
regulator to the desired liquid pressure (normally
between 20 and 50 psi). Collect all the water from one
nozzle for the same number of seconds taken to travel
the 205 feet.
Example: If it took 35 seconds to travel the 205 feet,
collect the discharge of one nozzle for 35 seconds.
BOOM WITH 20" NOZZLE SPACING: The number of fluid
ounces collected equals the gallons per acre (GPA) output.

OPERATING INSTRUCTIONS
BOOM WITH 10" NOZZLE SPACING: Two times the
number of fluid ounces collected equals the gallons
per acre (GPA) output.
Repeat this procedure two more times, collecting
water from a different nozzle each time. Use the
average number of ounces collected from the three
nozzles to determine the gallons per acre output of the
boom at the set pressure and selected RPM and gear
setting. Note: If the ounces collected from any nozzle
are 10% greater or less than the ounces collected
from any other nozzle, it is a sign of wear and all the
tips on the boom should be replaced.
To determine the amount of product to add to the
spray tank, divide the capacity of the tank by the
number of gallons of water per acre (GPA) to
determine the area, in acres, that can be covered with
a tankful of spray.
Example: 200 Gallon Tank divided by 20 GPA = 10
acres covered per tankful.
Multiply the application rate of the product per acre
times the acres per tankful and add that amount of
product to the tank through the strainer basket. The
tank should be one third filled with clean water with the
sprayer running under full agitation. After the product
is completely mixed, you would fill the tank to the
proper level with clean water.
Example: 2 quarts per acre x 10 acres per tankful =
20 quarts or 5 gallons of product to be added per
tankful of clean water.
To decrease the output: Adjust the pressure
regulator to a lower pressure that still maintains
the spray pattern; or increase the speed of the
tractor (truckster); or change the nozzle tips to a
smaller size.
To increase the output: Adjust the pressure
regulator to a higher pressure that still maintains
the spray pattern; or decrease the speed of the
tractor (truckster); or change the nozzle tips to a
larger size.

Tips on Spraying
a.Mixing Dry-Bagged Products for Sprayer Use
Dry-bagged products should be pre-mixed with clean
water in a five gallon container to form a slurry. The
sprayer should be one third filled with clean water and
running under full agitation. The slurry should be
slowly poured into the sprayer through the strainer
basket. After the product is completely mixed, you
would fill the tank to the proper level with clean water.\
b.Use of the MTD Pro Chemical Lawn Gun
Determine the application rate in gallons per 1000 sq.
ft. from the product label. Divide this figure by your
spraying pace in minutes per 1000 sq. ft. to determine
the proper flow rate for the gun in gallons per minute.
Use this figure to select the proper nozzle and then
calibrate the sprayer, to spray this flow rate. To use
the gun, hold it in your right hand (if you are right
handed) with the hose forming a loop, running under
your right arm to your back, over your left shoulder,
down across your chest and around and outfrom your
right side and back to the sprayer. Holding the hose in
this way takes the weight of the hose off of your right
arm and allows you to pull the hose with your whole
body and not just your arm.
If you are left handed, the above would be reversed.
Swing the gun with your wrist so that the pattern is in
constant motion and covers a swath about eight feet
wide. Start at the sprayer and work into the lawn. Walk
in parallel paths about eight feet apart and make sure
your spray pattern slightly overlaps the previous pass.
Keep the spray pattern away from ornamentals, trees
and gardens.
b.Use of the MTD Pro Spray Wand
The MTD Pro Spray Wand consists of a ball valve
which controls the width of the pattern, a handle, a
trigger valve which turn's the flow on and off, an
extension, a screen strainer, a hex chamber which
controls the flow to the tip, a brass tip and a nut to
hold the tip in place. The tip throws the best pattern at
a pump pressure of about 40 psi. The tip launches a
fan shaped pattern about eightfeet wide with a droplet
size large enough to help avoid drift.
Determine the application rate in gallons per 1000 sq.
ft. from the product label. Divide this figure by your
spraying pace in minutes per 1000 sq. ft. to determine
the proper flow rate for the wand in gallons per
minute. Use this figure to calibrate the sprayer to
spray this flow rate.
To use the wand, hold it in your hand with the hose
running around your body as described in the section
on the MTD Pro Chemical Lawn Gun. Hold the wand
so that the tip is 18 to 24 inches above the ground and
the spray pattern covers a swath about eight feet
wide. Hold the wand steady and lock the trigger on.
Start at the sprayer and work into the lawn. Walk in
parallel paths about eight feet apart and make sure
your spray pattern slightly overlaps the previous pass.
Use the ball valve to control the pattern width to keep
the spray pattern away from ornamentals, trees and
gardens.
The MTD Pro Spray Wand with the high volume tip is
MTD Pro No. 590-526-195.

OPERATING INSTRUCTIONS
Cleaning the Sprayer
After use, flush the sprayer tank, and the entire
system, pump, plumbing, hoses and gun, wand or
boom with Nutra-Sol to neutralize chemicals and
reduce pump problems. Follow the instructions on
the label. Extra cleaning care should be taken after
spraying herbicides to prevent possible damage to
turf or plants when next spraying insecticides or
fungicides. After the sprayer has been flushed,
clean the in-line strainer. Hose off the outside of
the sprayer to wash off dust and dirt. Do not spray
water on the engine if it is hot.
MAINTENANCE INSTRUCTIONS
A.ENGINE MAINTENANCE SCHEDULE
Complete maintenance procedures for the engine
installed on your MTD Pro Sprayer can be found in the
engine Operating and Maintenance Instructions
furnished with the sprayer.
Daily Checks: Check, the gasoline, level. Check the
engine oil level.
After the First 5 Hours: Change the engine oil.
Every 50 Hours: Change the engine oil. Change the
oil every 25 hours if the engine is operated under
heavy load or in high ambient temperatures.
Every 100 Hours: Change the gear reduction oil.
Remove the blower housing and clean the cooling fins.
Clean the spark plug and reset the gap. Remove the
cylinder head and the cylinder head shield and remove
combustion deposits from the cylinder, the cylinder
head, the top of the piston and around the valves.
B.BATTERY
DANGER: ALWAYS WEAR SAFETY
GLASSES AND RUBBER GLOVES WHEN
WORKING ON THE BATTERY. KEEP
SPARKS AND FLAMES AWAY AT ALL
TIMES.
The battery used to operate the reel on other sprayers
should be maintained as follows.
Remove the fillcaps and check the level of the liquid
electrolyte in the battery every 50 operating hours. If
the level in any of the six cells has dropped below the
bottom of the split ring inside the fill hole, refill the cell
with distilled water. DO NOT OVERFILL THE
BATTERY. To keep the outside of the battery clean,
brush on a strong solution of bicarbonate of soda and
water and rinse with clean water. Keep the contacts
and cable ends clean with a wire brush and make sure
the connections are tight. Coat the terminals with
petroleum jelly to prevent corrosion.
C.PUMP
Diaphragm pumps require very little maintenance. The
procedures that are required are listed in the pump
Installation/Operation Instructions furnished with the
sprayer.
Daily Checks: Check the oil level. The oil must be
halfway up the sight tube. Make certain there are no
kinks in the suction line and that the suction line
connections are tight. Check the air pressure in the
pulsation damper. It should be at least 10% of the
expected operating pressure. After use, flush out the
pump. See the section on Cleaning the Sprayer
indicated above.
Every 200-Hours and at the End of Each Spray
Season: Change the oil.
At the End of Each Spray Season: Change the
diaphragms.
To change the diaphragms, you need a set of metric
wrenches and a set of metric allen wrenches. First,
drain the oil from the crankcase. The larger pumps
have a drain plug for this purpose. The smaller pumps
must be removed from the sprayer, the oil cap removed
and the pump turned upside down to drain the oil.
Rotate the shaft until all the oil is drained. Then remove
the manifold nuts and the head nuts. Work on one head
at a time. Remove the manifold and the head. Remove
the diaphragm nut, the retaining washer and the
diaphragm. Turn the crankshaft to bring the piston to its
downstroke and seat the new diaphragm into the sleeve
groove. Replace the retaining washer and tighten the
diaphragm nut. Reinstall the head. Replace the other
head diaphragms and then replace the manifold. To
replace the pulsation damper diaphragm, bleed the air
from the damper. Remove the bolts holding the damper
assembly together. Replace the diaphragm and replace
the bolts. Recharge the damper with air pressure to
10% of the expected operating pressure. Remount the
pump on the sprayer and refill the crankcase with oil.
D.AGITATOR
Most of the fiberglass sprayers have mechanical
agitation and the agitator grease fittings on the front
and rear of the tank should be greased after each 8
hours of operation. The two agitation packing gland
nuts on the front of the tank, behind the belt guard,
should be tightened as needed to eliminate dripping.
Tighten the adjusting nuts equally, 90° at a time, to
compress the packing evenly until the dripping is
stopped. Replace the packing when dripping cannot
be stopped.

MAINTENANCE INSTRUCTIONS
E.BELT ADJUSTMENT
DANGER: DO NOT ATTEMPT TO ADJUST
THE BELTS WHILE THE ENGINE IS
RUNNING.
The pump and agitator on the fiberglass sprayers are
belt driven. These belts will stretch when new and it is
very important that the belts be checked for proper
tension daily for the first three or four days of
operation.
NOTE: DO NOT TIGHTEN THE AGITATOR BELT
MORE THAN NECESSARY OR YOU WILL DISTORT
THE PACKING GLAND.
The proper procedure for tightening the belts is as
follows:
1. Loosen the engine mounting bolts.
2. Loosen the pump mounting bolts.
3. Loosen the engine-to-pump belts. Turn the
engine adjusting bolt found at the end of the
engine mounting plate so that the engine moves
toward the pump.
4. Tighten the agitator belt. Turn the pump
adjusting bolt found at the end of the pump
mounting plate so that the pump moves toward
the outside edge of the sprayer.
5. Tighten the pump mounting bolts.
6. Tighten the engine-to-pump belts. Turn the
engine adjusting on found at the end of the
engine mounting plate so that the engine moves
toward the outside edge of the sprayer.
7. Tighten the engine mounting bolts.
NOTE: Steps 2, 3, 4 and 5 may be eliminated if it is not
necessary to tighten the agitator belt.
F.TANK
The sprayer tank requires no scheduled maintenance.
The inside of the tank should be flushed out after each
use as described in the section on Cleaning the
Sprayer. The outside of the tank should be hosed off
after use and scrubbed occasionally with soapy water
to remove ground-in dirt.
G.IN-LINE STRAINER
The in-line strainer should be cleaned each day after
the sprayer has been flushed. Place a flat pan under
the strainer bowl to catch the liquid and unscrew the
bowl. Note: There is a washer-like seal between the
top lip of the bowl and the strainer body. This seal will
sometimes come off on top of the bowl or will drop out
of the strainer body when the bowl is unscrewed. DO
NOT LOSE THIS SEAL! It must be installed or you
won't be able to operate your sprayer.
H.HOSE
If the hose on your sprayer is treated carefully, it will
give long and trouble free service. When you have
finished spraying a lawn, carry the application device
and drag the hose back to the sprayer. This protects
the application device from being damaged by being
dragged through the turf and permits you to insure, as
you walk back to the sprayer, that the hose is not
snagged on something or wrapped around a tree. It
also eases the load on your reel because the hose will
be rewound from only half the distance. The hose
should be flushed out daily as described in the section
on Cleaning the Sprayer. Weekly, you should clean off
the outside cover of the hose by rewinding it onto the
reel while gripping it lightly with a rag dipped in soapy
water.
I.STORAGE AND WINTERIZING
If the sprayer will not be used for 30 days or more it
should be thoroughly flushed out and cleaned as
described in the section on Cleaning the Sprayer. The
engine should be drained of fuel to prevent gum
deposits from forming on essential carburetor parts.
First, the fuel tank should be drained and then the
engine should be started and allowed to run until it
stops from lack of fuel. While the engine is still warm,
the oil should be drained from the crankcase and then
the crankcase refilled with fresh oil. The spark plug
should be removed, a teaspoon of oil poured into the
cylinder, the engine cranked slowly to distribute the oil
and the spark plug replaced. The blower housing
should be removed and any dirt should be cleaned
from the engine's cooling fins. You should change the
oil in the pump every 200 hours and at the end of the
spraying season. You should change the pump's
diaphragms at the end of each spraying season.
The sprayer should be stored in a clean, dry area
which should be heated if freezing weather will occur
during the time of storage. Pour a gallon of antifreeze
and a gallon of clean water into the sprayer. Start the
engine and agitate the mixture. Then pump the
antifreeze mixture through the plumbing and discharge
it from the application device back into two one gallon
containers. Store the 50/50 antifreeze mixture for
future use. If a boom is your application device, spray
a small amount of the antifreeze mixture from the
boom and then shut it off and drain the rest of the
mixture from the tank using the drain on the front of the
sprayer.
