3. OPERATING INSTRUCTIONS
3.1 CONTROLS
oThe user should become familiar with all controls before operating the machine.
Handlebars: The handlebars provide steering control of the machine and should be grasped
with the hands at the location of the foam grips.
Throttle lever: The throttle lever is located at the end of the right hand side of the
handlebars. Squeezing the throttle lever increases the speed of the engine. Releasing the

8
throttle lever allows the engine to return to idle speed. When the transmission is engaged
in any position other than neutral, squeezing the throttle will cause the machine to move
relative to the gear that has been selected. The more the lever is squeezed, the greater the
speed of the machine.
Brake pedal: The brake pedal is located in the middle of the operator platform. Depressing
the brake pedal engages the band brakes on the rear wheels and slows the motion of the
machine.
Gate lever: The gate lever is located on the left side of the console and controls the opening
at the bottom of the hopper. Pushing forward on the gate lever causes the gate to close so
that no granular product will flow out of the bottom of the hopper. Pulling backward on the
gate lever causes the gate to open so that granular product will flow.
Engine ignition switch: The engine ignition switch is located on the left side of the console
and controls the ignition circuit of the engine. The engine will only start and run when the
switch is in the “ON” position. The engine will not start or will shut down if the switch is in
the “OFF” position.
Spread control lever: The spread control lever is located on the right side of the console
and controls the center of the granular spread. The lever controls the position of a baffle
located below the gate of the hopper. As this baffle is moved relative to the gate opening,
the center of the dispensed material changes. To operate, the lever is first unlocked by
rotating counterclockwise. The handle can then be moved up and down to change the
position of the baffle. Once the correct position is found, the handle is rotated clockwise to
lock the lever in place.
Gate stop: The gate stop controls the maximum opening of the hopper gate and is located
on the front of the hopper. The knob is rotated one direction or the other until the desired
maximum gate opening is obtained.
3.2 PRE-START
oFill the fuel tank. For best results use only fresh, clean regular grade unleaded gasoline with an
octane rating of 87 or higher. Do not add oil to the gasoline.
oDo not overfill the fuel tank. Never fill the fuel tank so that the fuel level rises above a level that
is ½” below the bottom of the filler neck. This will allow for fuel expansion and will help to
prevent fuel spillage.
oUnderstand the controls, their locations, their functions, and their safety requirements.
oRefer to Maintenance, Section 5, and perform all the necessary inspection and maintenance
steps.
3.3 STARTING THE MACHINE
oPosition the machine on a flat and level surface.
oEnsure that the transmission is in the neutral (N) position and that the engine ignition switch is
in the “ON” position.
oOpen the fuel shut-off valve located on the engine.
oIf the engine is cold, activate the choke lever located on the engine. If the engine is warm, it
may not be necessary to activate the choke lever.
oFirmly grasp the handle of the start cord and pull the handle toward the rear of the machine.
Do not squeeze the throttle lever when starting the machine.
oOnce the engine has started, gradually deactivate the choke lever.
oCarefully step onto the operator platform.
oMove the transmission lever to the desired location.
oSlowly squeeze the throttle lever to start the machine moving.

3.4 SHUTTING DOWN THE MACHINE
oPosition the machine on a flat and level surface.
oCompletely release the throttle lever.
oMove the transmission lever to the neutral (N) position.
oMove the engine ignition switch to the “OFF” position.
3.5 TRANSPORTING THE MACHINE
oUse a heavy-duty trailer or hitch-mounted rack to transport the machine. Securely fasten the
machine to the trailer or rack with straps, chains, cable, or ropes. Make sure that the trailer or
rack has all of the necessary lighting and markings that are required by law. If using a trailer,
make sure that the safety chains are secured.
oUse extreme caution when loading the machine on a trailer or rack. The ramps should be long
enough so that the angle between the ramp and the ground does not exceed 15°. A steeper
angle may cause the machine to lose traction and slide out of control.
oAlways load the machine with the machine driving forward.
oOnly use first gear (1) when loading the machine.
oKeep the machine in gear once it has been properly loaded and shut off. This will help to
minimize movement of the machine on the trailer or rack during transportation.
3.6 OPERATING THE SPREADER
oThe spreader has a pattern width of approximately 14 feet. By using passes with an
approximate 7 foot width, the granular product will be evenly distributed with the proper
amount of overlap.
oAdjust the gate stop to the desired setting.
oCompletely close the hopper gate and add fertilizer to the hopper.
oInstall the hopper shower cap if necessary.
oCarefully step onto the operator platform.
oPlace the gear selector in second gear (2).
oSqueeze the throttle lever to start the machine rolling forward.
oSlide the gate lever to the OPEN position.
oTo stop the spreading operation, slide the gate lever to the CLOSED position, release the throttle
lever, and depress the brake pedal.
4. CALIBRATION
4.1 SPREADER FLOW RATE CALIBRATION
oThe following instructions provide a method for adjusting the flow of fertilizer from the hopper
so that the correct amount of fertilizer is applied to a 1000 ft2area. The machine is designed to
apply fertilizer evenly by overlapping each pass by 50 percent. The spread width for most
products is approximately 14 feet. This means that the center of each pass should be
approximately 7 feet from the center of the previous pass. The effective material spread width
is 7 feet and is the basis for calibration.
oMeasure a distance of 143 feet on a flat paved surface. Using a paved surface will allow the
fertilizer to be recollected and will prevent burning the turf if the application rate is largely
different from what is intended. Traveling 143 feet with the machine equates to covering
approximately 1000 ft2with fertilizer (7 ft x 143 ft = 1001 ft2).
oSet the gate stop to a setting of 5. This will be used as the starting setting for dialing in the
correct gate stop setting for the particular material that is being used. Note that the spreader

10
will have to be recalibrated for each different type of material that is spread. Make sure to
record the final gate stop setting once the correct application rate has been achieved.
oPlace the spreader gate lever in the CLOSED position. Place enough material in the hopper to
cover 1000 ft2.
oBegin the spreading operation while moving toward the 143 foot marker. With the machine
moving at full speed, the hopper should just empty out as the machine passes the marker. If the
hopper empties before the marker is reached, turn the gate stop dial to a slightly lower setting
and repeat the process. If the hopper empties after the marker is reached, turn the gate stop
dial to a slightly higher setting and repeat the process. Continue this process until the proper
dispensing rate is achieved.
oWhen the calibration is complete, collect the fertilizer that has been dispensed for reuse. Never
leave the fertilizer on the pavement where it can wash away in runoff.
4.2 CENTERING THE SPREAD PATTERN
oThe following instructions provide a method for adjusting the center of the spread pattern so
that fertilizer is evenly distributed over the width of the spread area.
oObtain the following items:
Eleven collection pans, 3 to 4 inches tall and 12 inches square (e.g. aluminum roasting
pans).
Clear tube, ½” internal diameter, 4 inches tall. Use a permanent marker to mark the
tube at ¼” increments all of the way up the tube. This will act as a measuring device for
the collected fertilizer prills.
A ruler or tape measure.
A method of recording the collection amounts.
oSet the gate stop to a setting of 5.
oMove the gate lever to the OPEN position (the hopper must initially be empty).
oTurn the spread control lever counterclockwise to release the lock and move the lever in or out
so that the baffle can be seen centered just below the opening of the gate in the bottom of the
hopper. Turn the spread control lever clockwise to lock into position.
oMove the gate lever to the CLOSED position.
oLoad the hopper with the fertilizer to be used for calibration.
oPlace the eleven collection pans on a flat paved surface in a straight line on two-foot centers.
Using a paved surface will allow the fertilizer to be recollected and will prevent burning the turf
if the application pattern is largely different from what is intended.
oMake at least three passes traveling directly over the center pan in a path perpendicular to the
row of pans. NOTE: All of the passes must be made in the same direction.
oPour the contents of the first pan on the left into the graduated tube and record the amount of
material that is in the tube. Repeat this measurement for each of the eleven collection pans.
oAdd together all of the eleven numbers to find the total material that was dispensed.
oDivide the amount caught in each pan by the total amount. This is the percentage that was
caught in each pan.
oThe distribution should increase towards the center pan and decrease toward the outside pans.
The distribution should also be approximately the same on each side. If it appears that the left
