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.

Oil bearing in  
the hopper  
Figure 10  
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.
