Fasteners
Operation
IMPORTANT!
The Fastener Bag contains these
fasteners. Most are all common parts;
replacements are available at local
hardware outlets.
Always begin moving the spreader
before you open the control by
pushing the thumb release to the ON
position, and push the control knob in
to CLOSE before stopping.
CAUTION!
During operation, always push the
spreader; never pull!

5. Hold the handle so the top of the
hopper is level. Start the spreader
moving, then push the thumb
release to the ON position and
begin applying the material. Avoid
tipping the spreader; doing so can
cause an uneven application.
Figure 8
1. Place the spreader on a driveway or
sidewalk – not on the lawn. Make
sure the spreader is off by pushing
the control knob in. See Figure 8.

2. Determine the recommended
application and spreader settings of
the material to be applied (check
the product container).
IMPORTANT!
The settings and swath widths 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,
walking speeds, and the condition of
the product being applied.
See pages 6-7 for details.
Figure 9
3. Rotate the rate cam to the proper
setting. See Figure 9.
4. Fill the hopper with the product to
be spread.

Maintenance
Operation
■ Never store unused material in the
spreader. Return unused material
to its original container.
■ Wash the spreader thoroughly after
each use. See Figure 12. Remove
the gear cover and wash the gears
thoroughly. Then dry completely in
the sun or a heated area.
Effective swath
width approximately
10-12 feet on center.
■ Lubrication
a. Lubricate the face of the gear
teeth with dry graphite.
Reinstall the gear cover.
b. Lightly oil the axle bearings in
the frame. See Figure 13.
Figure 12
c. Apply oil to the impeller shaft
bearing in the hopper, pivot
points on the shut-off plate,
and the spring in the housing
behind the control plate.
See Figure 13.

6. Where appropriate, apply header
strips around the area to be treated,
then push the spreader at a walking
speed about 2 1/2 mph (18 feet in
five seconds). To decrease the
spread width in confined areas,
reduce walking speed. Space your
trips across the area as shown in
Figure 10.
■ Gear mesh should be checked
regularly, especially during high-
use periods. The clearance between
the axle gear and the pinion gear
should be very close, but not tight.
If adjustment is required:
Oil
a. Loosen the axle collar set screw
and hold the gears together.
7. When transporting the spreader,
make sure the control knob is
pushed in and locked.
Figure 13
b. Hold the axle gear lightly
against the gear support and
tighten the axle collar set
screw.
Axle
Collar
8. Empty the spreader after each use,
and return leftover material to its
original container.
c. Spin the drive wheel to make
sure the gears run freely and
smoothly. See Figure 14.
Oil
■ Periodically clean the surface of the
impeller to remove buildup of
material. A buildup could cause the
spread pattern to change.
Dry Graphite
■ Maintain tire pressure at 20–25 psi.

Spreader Settings
When determining correct spreader
settings, consider:
Rate Setting Conversion
a. Divide the weight of a container
of material by the recommended
square-foot coverage.
The following is a comparison of the
settings of a Shindaiwa 75RS with the
equivalent approximate settings of
other spreaders.
■ Effective Pattern Width: The
actual width in which the material
is applied. Label instructions and
settings are useful guides, but only
an actual test can provide a reliable
and accurate pattern width.
b. Multiply the result by 100 (add
two zeros).

3. Measure out an area of 100 square
feet (10 by 10 feet).
You can make a simple visual
pattern test by operating the spreader
over a non-turf area and evaluating the
pattern.
A more accurate method is to place
a row of disposable aluminum cake
pans about 1 foot apart on centers as
shown in Figure 11. Set the rate
control at the middle setting (see
Operation, Step 3, Figure 11,) and
make three or four passes in the same
direction. See Figure 11.
Pour the material collected in each
cake pan into individual bottles or jars
of the same size, then set them side by
side in the order they were collected
and inspect the containers.
The Effective Pattern Width is the
distance out from the spreader to a
point where the amount of material is
1/2 the amount in the center pans.
Weigh out 15 to 20 pounds of material
and spread it over the measured 100
square-foot area, applying in 10-foot
swaths (10-foot Effective Pattern
Width). Weigh the material remaining
in the hopper and adjust the discharge
chute as required.
