Operation Place the spreader on a driveway or sidewalk – not on the lawn. Make sure the screen is in position in the hopper and the spreader control lever is in the OFF position and locked with the hitch pin: 1. Determine the recommended application and spreader settings of the material to be applied (check the product container). 2. Loosen the rate control knob and slide the rate control plate until the letter code of the desired application rate aligns with the pointer. Tighten the rate control knob. See Figure 6.

5. Check the delivery rate and pattern on a small area before treating a large area. Actual delivery can vary according to weather and operating variables, such as walking speed and the condition of the material. Refer to the Rate Setting Conversion chart and Spreader Settings for details. 6. Where appropriate, apply header strips around the area to be treated, then push the spreader at a walking speed about 21⁄2 mph (18 feet in five seconds). Space your trips across the area as shown. See Figure 7. 7. When transporting the spreader, make sure the control lever is OFF and locked with the hitch pin through the hole in the lever. 8. Empty the spreader after each use, and return leftover material to its original container.

3. Fill the hopper with the product to be spread. IMPORTANT! Always begin moving the spreader before you shift the control lever to OPEN, and shift the control lever to CLOSE before stopping.
Use swath width on the package, or adjust according to operators walking speed.
CAUTION! During operation, always push the spreader; never pull! 4. Hold the handle so the top of the hopper is level, remove the locking hitch pin from the control lever and move the lever forward to begin applying the material. Avoid tipping the spreader; doing so can cause an uneven application.

IMPORTANT!
The RS75/RS75s rate plate is black with white lettering and the RS75 rate plate is red with white lettering. Using the incorrect settings in this chart will result inthe improper application of the product being used. Fertilizer Particle Size This charts provides approximate settings of a Shindaiwa RS75/RS75s when only the product weight, area coverage, or inspection of the material is available.

Conversions should only be used as guidelines for establishing rate settings. To obtain the most accurate application rate, follow the procedures described in the Effective Pattern Width and Application Rate sections.

The settings shown here are only approximations and will vary with walking speed, turf condition, humidity, etc. Warranties and guarantees of actual coverage or uniformity are neither expressed nor implied.

Spreader Settings When determining correct spreader settings, consider: ■ 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. ■ Application Rate: The amount of material applied per 1000 square feet (before you can determine application rate, you must know the effective pattern width).
Effective Pattern Width 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 8. Set the rate control plate at the middle setting (see Operation, Step 2, page 6, ) and make three or four passes in the same

direction. 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. If the pattern of collected material is not equal – if a left hand-bottle contains a different amount than its equivalent right-hand bottle – adjust the discharge chute until the pattern is even. See Pattern Adjustment. Once the pattern is uniform, you can determine Effective Pattern Width which is— Half the average amount of material in the center cake pans, multiplied by two.
Pattern Adjustment The application of most materials requires no adjustment unless stated on the material container; the RS75/ RS75s is factory set at “A”, the most common pattern setting. If pattern adjustment is required: 1. Loosen the two discharge chute knobs and move the discharge chute closer or farther from the impeller as required. The discharge chute base is marked with letters “A”, “B” and “C” as reference. See Figure 9. 2. Retighten the two knobs. Discharge Chute

Calibration Instructions Application Rate Calculate application rate as follows: 1. Determine the Effective Pattern Width. See the previous page. For example: ■ Effective Pattern Width is determined to be 10 feet. 2. Determine the coverage requirement of the material to be spread in pounds per 100 square feet. This can be calculated as follows: a. Divide the weight of a container of material by the recommended square foot coverage. b. Multiply the result by 100 (add two zeros). For example: ■ According to the label on the container, 25 pounds of material will cover 5000 square feet.
The RS75/RS75s spreader was calibrated at the factory. However, calibration should be checked periodically to ensure best performance. 1. Pull the control lever to the OFF position and set the rate control plate to setting “A”. See Figure 10. 2. Put the control lever to the ON position and check the port opening. See Figure 11. The port should be just opened. If adjustment is necessary, continue to Step 3. 3. Loosen the rate control knob and slide the rate control plate until the port is just opening. Loosen the pointer screw and move the pointer until it aligns with “A” on the rate control plate. Retighten the pointer screw.
■ Calculate average coverage requirement– 25 lbs 5000 000.5 100 0.5 pounds per 100 square feet 3. Measure out an area of 100 square feet (10 by 10 feet). 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. Repeat the test until the application rate is correct.
