1. Remove the spreader and
components from carton and
place hopper up-side down on
a padded surface as shown.
Slide drive and free wheel
onto axle as shown with the
longer portion of wheel hub
facing the frame. Secure free
wheel with (1) 1/8 dia. x 1 1/4”
cotter pin. Attach drive wheel
to axle with (1) 3/16 dia. x 2”
cotter pin.
3. Turn spreader upright on
wheels. Insert screen into
hopper sliding it under the
screen clips. Attach the upper
handle assembly to handle
brace with the handle lever
facing as shown. Secure with
(2) 1/4-20 x 1 1/2” carriage
bolts, and locknuts.
2. Attach leg/brace to frame as
shown using (4) 1/4-20 x 2 1/4”
carriage bolts and locknuts.

1. Check the product package for the rate
setting, and recommended swath width. Loosen
rate control knob and slide rate plate to the
proper setting. The pattern is controlled by
loosening the two knobs on the discharge chute
and moving the chute closer or farther away
from the impeller (setting A, B, or C). See
“PATTERN ADJUSTMENT” for details.
2. Always fill the spreader on the driveway or
sidewalk-not on the lawn. Make sure screen is in
hopper and spreader is in the “OFF” position .
3. Start spreader moving before opening port.
Close before stopping. Always push spreader,
never pull.
4. Hold handle so top of spreader is level.
Tipping the spreader too far can cause uneven
spreading.
5. The settings and swath widths on the product
label are recommended starting points. Always
check the delivery rate and pattern on a small
area before treating a large area. Actual delivery
rate can vary due to weather conditions,
operating variables, and condition of the
product being applied. See “HOW TO
DETERMINE SPREADER SETTINGS AND
SPREAD WIDTH” for details.

6. Push spreader at a normal walking speed -
2 1/2 m.p.h. (18 feet in 5 seconds). Apply
header strips around area to be treated.
Space trips across the area as shown. Keep
material off flower beds, sidewalks, etc.
7. When transporting spreader, make sure that
it is in the “OFF” position.
8. Empty spreader after each use. Return
leftover material to its original container.

PATTERN ADJUSTMENT
PATTERN ADJUSTMENTPATTERN ADJUSTMENT
PATTERN ADJUSTMENT
Normal spreading of materials
requires no adjustment (factory
setting “A”) unless stated on the
package. In those cases where the
spread pattern has shifted, the
pattern can be adjusted left and
right by loosening the two knobs on
the discharge chute and moving the
chute closer or farther away from
the impeller. Settings of “A, B, and
C” are provided as reference.

A simple visual pattern test can be made by
operating the spreader over a non-turf area
and evaluating the pattern. A more accurate
method is to place a row of common,
disposable, aluminum cake pans
approximately 1 foot on centers. Set the rate
plate at a middle setting and make 3 or 4
passes in the same direction as shown.
Pour the material collected from each pan
into individual bottles of the same size. Set
them side by side in order, and visually
inspect their volume. If the pattern is not
centered (example: volume in bottle #2 left
not equal to bottle #2 right), adjust the
discharge chute up or down as described in
“PATTERN ADJUSTMENT” section.

SETTINGS AND SPREAD WIDTH
SETTINGS AND SPREAD WIDTHSETTINGS AND SPREAD WIDTH
SETTINGS AND SPREAD WIDTH
Two major factors should be considered when determining correct spreader settings of any product:
1. The product application rate, or the amount of material applied per 1,000 square feet.
2. The effective pattern width, or the actual width in which material is applied. Label settings are a
guide and can be affected by numerous factors.
EFFECTIVE PATTERN WIDTH
EFFECTIVE PATTERN WIDTHEFFECTIVE PATTERN WIDTH
EFFECTIVE PATTERN WIDTH
Once the pattern is uniform, the effective pattern width
can be determined. The effective pattern width is the
distance out from the spreader to a point where the
amount of material is 1/2 the average amount in the
center pans. This distance is multiplied by 2 to achieve
the total effective pattern width.

Knowing the effective pattern width (for
example, 10 feet), measure a distance equal
to 100 square feet (10’ x 10’ swath width).
Determine the product coverage in pounds /
100 sq. ft. by taking the weight of the product
and dividing it by the recommended square
foot coverage (add two zeroes to the weight
of the bag).
EXAMPLE: Product weight: 25 lbs.
sq. ft. coverage: 5,000 sq. ft.
2500 lbs. - 5,000 sq. ft.
= .5 lbs. / 100 sq. ft.
Weigh out 15 to 20 lbs. of material and
spread over the 100 sq. ft. area. Weigh
remaining material left in hopper and
adjust rate setting as required. Repeat
test until application rate is correct.

The following provides approximate Shindaiwa RS76/RS76S settings when only the product weight, square
foot coverage, and visual inspection of the material is available.
The conversions should be used as guidelines for establishing proper rate settings for the particular product being applied. Steps for
obtaining the most accurate settings are outlined in the “How to Determine Spreader Settings and Spread Width” section of this manual.
These settings are approximate and may vary due to physical characteristics of the product. Walking speed, wear, condition of the turf
and humidity, may cause actual rate setting to deviate. No expressed nor implied warranty or guarantee is provided as to coverage or
uniformity indicated by these rate settings.
1. Never store unused material in spreader. Return
unused product to its original container.
2. Wash spreader thoroughly after each use and dry
completely in sun or heated area.
3. Grease axle bearings in frame. Oil the impeller shaft
bearing in hopper, pivot points on the shut-off plate
and the spring in the housing behind the rate plate.
4. Remove gear cover and wash gears thoroughly. Oil
all bearing areas and face of gear teeth. Lubricate gear
teeth with dry graphite. Re-install gear cover.
5. Gear mesh should be checked on a regular basis
during high use periods. Clearance between the axle
gear and pinion gear should be minimal but not tight. If
adjustment is necessary, loosen axle collar set screw
and hold gears together. Slide axle collar against the
gear support and tighten axle collar set screw. Spin
drive wheel. Gears should run freely and smoothly.
6. Impeller surface should be cleaned periodically to
remove build-up of product. Build-up can cause the
spread pattern to change.
7. Tire pressure should be 20-25 PSI.

The shindaiwa RS76/RS76S was factory calibrated, however, calibration should be checked
occasionally to assure optimum performance.
1. Pull the on/off lever to the “OFF” position.
Set the rate control plate to setting “A”.
3. Loosen the rate control knob and slide the rate
plate until the port is just opening. Loosen
pointer screw and move pointer until it aligns
with “A” on the rate plate. Retighten pointer
screw.
2. Flip on/off control lever to the “ON” position.
Check the port opening. It should be just open.
If adjustment is necessary, continue to step #3.
