HOW TO USEYOUR SPREADER
SETTING THE FLOW CONTROL
(Refer to figure 13 on page 7.)
8' to
10'
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.

FIGURE 14
USINGYOUR 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. Beforefillingthehoppermakesuretheflowcontrolarm
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.Avariationinspeedwillrequireanadjustment
of the flow rate to maintain the same coverage. The
faster you walk, the wider the broadcast width.
6. Always start the spreader in motion before opening
the closure plate.
IMPORTANT: Application rates shown in the chart are af-
fectedbyhumidityandbythemoisturecontentofthematerial
(granular and pellet). Some minor setting adjustments may
be necessary to compensate for this condition.

small area, soak the area thoroughly with a garden
hose or sprinkler to prevent burning of the lawn.

MAINTENANCE
STORAGE
CHECK FOR LOOSE FASTENERS
1. Rinse inside of hopper and exterior of spreader and
dry off before storing.
2. Store in a clean, dry area.
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.
SERVICE AND ADJUSTMENTS
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.
CHECK TIRE INFLATION
3. Check if tires are adequately inflated before each use.
Do not inflate tires beyond maximum recommended
pressure.
CAUTION: DO NOT inflate tires beyond the
maximum recommended pressure printed
on side of tire.
2. If the agitator hairpin becomes damaged or worn it can
be replaced. Remove old agitator hairpin from hole in
sprocket shaft and replace with new agitator hairpin.
See figure 16.
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
SHAFT
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 at least once a year or more
often as needed.
