22. Place the adjustable stop into the "ON" end of the
slot in the top of the flow control mounting bracket.
Secure with the 1/4" x 3/4" carriage bolt, a nylon
washer, a 5/16" flat washer and the nylon wing nut.
See figure 12.
23. Position the flow control mounting bracket (figure
13).
a. Push on flow control arm until it locks in "OFF"
position.
b. Slide flow control mounting bracket along tube
until closure plate in bottom of hopper just closes.
c. Snug the 1/4" lock nuts just enough to hold flow
control mounting bracket in place.
d. Set adjustable stop at "5". Pull flow control arm
against stop. Verify that closure plate has opened
about half way.
e. If closure plate does not open half way, it may be
closed too far at "OFF". Adjust position of flow
control mounting bracket until closure plate will
open about half way at "5" and still close when
arm is locked in "OFF". Tighten 1/4" lock nuts.

HOW TO USE YOUR SPREADER
SETTING THE FLOW CONTROL
(Refer to figure 13 on page 7.)
1. Loosen the nylon wing nut, set the adjustable stop to
the desired flow rate setting and retighten the wing
nut. The higher the setting number, the wider the
opening in the bottom of the hopper.
2. Refer to the application chart on page 8 and to the
instructions on the fertilizer bag to select the proper
flow rate setting.
3. Pull the flow control arm against the adjustable stop
for the on position and toward the hopper for the off
position.
OPERATION
USING YOUR SPREADER
We do not recommend the use of any powdered lawn
chemicals, due to difficulty in obtaining a satisfactory or
consistent broadcast pattern.
1. Determine approximate square footage of area to be
covered and estimate amount of material required.
2. Before filling the hopper make sure the flow control
arm is in the off position and the closure plate is shut.
3. Break up any lumpy fertilizer as you fill the hopper.
4. Set the adjustable stop with the flow control arm still in
the off position. Refer to the application chart on this
page and to the instructions on the fertilizer bag to
select the proper flow rate setting.
5. The application chart is calculated for light to heavy
application at a walking speed of 3 mph, or 100 ft. in
23 seconds. A variation in speed will require an
adjustment of the flow rate to maintain the same
coverage. The faster you walk, the wider the broad-
cast width.
6. Always start the spreader in motion before opening
the closure plate.
7. Always shut the closure plate before turning or stop-
ping the spreader.
8. If fertilizer is accidentally deposited too heavily in a
small area, soak the area thoroughly with a garden
hose or sprinkler to prevent burning of the lawn.
9. To insure uniform coverage, make each pass so that
the broadcast pattern slightly overlaps the pattern
from the previous pass as shown in figure 14. The
approximate broadcast widths for different materials
are shown in the application chart on this page.
10. When broadcasting weed control fertilizers, make
sure the broadcast pattern does not hit evergreen
trees, flowers or shrubs.

IMPORTANT: Application rates shown in the chart are
affected by humidity and by the moisture content of
the material (granular and pellet). Some minor set-
ting adjustments may be necessary to compensate
for this condition.

CHECK FOR LOOSE FASTENERS
1. Before each use make a thorough visual check of
the spreader for any bolts and nuts which may have
loosened. Retighten any loose bolts and nuts.
CHECK FOR WORN OF DAMAGED PARTS
2. Check for worn or damaged parts before each use.
Repair or replace parts if necessary.
CHECK TIRE INFLATION
3. Check if tires are adequately inflated before each use.
Do not inflate tires beyond maximum recommended
pressure.
1. Rinse inside of hopper and exterior of spreader and
dry off before storing.
2. Store in a clean, dry area.
CAUTION: DO NOT inflate tires beyond
the maximum recommended pressure
printed on side of tire.
CLEANING
4. Rinse inside of hopper and exterior of spreader and
dry off before storing.
LUBRICATE (See figure 15)
5. Lightly apply automotive grease as needed to the
sprocket and gear.
6. Oil the nylon bushings on the vertical sprocket shaft
and on the axle at least once a year, or more often as
needed.
7. Oil right hand (idler) wheel bearing at least once a year
or more often as needed.
MAINTENANCE STORAGE
1. If the axle, slotted gear and sprocket assembly is
disassembled, mark down the positions of the parts as
they are removed. The drive wheel and sprocket
positions in relation to the slotted gear determine
which direction the spreader plate will spin. Be sure to
reassemble them in their original positions. (Refer to
figure 3 on page 4.) Use shim washers (Ref. no. 21 on
pages 10 and 11) as needed for minimum backlash.
Add grease to gear and sprocket.
2. If the agitator hairpin becomes damaged or worn it
can be replaced. See figure 16.
