Operation Fasteners 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:. 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. Pointer Figure 6 Rate Control Knob Rate Control Plate. 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. CAUTION! During operation, always push the spreader; never pull! 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 2 2 mph (8 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. Header Strip Use swath width on the package, or adjust according to operators walking speed. The Fastener Bag contains these fasteners, shown actual size. They are all common parts; replacements are available at local hardware outlets (all metal fasteners are made of stainless steel). 4 dia. x 2" Clevis Pin Nut (8 req d) (2 req d) Split Lockwasher (8 req d) 4" dia. 4-20 Hex The following is a list of additional fasteners used in the manufacture of the RS75/RS75s Spreader, but are not shown on the Illustrated Parts List (next page).

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.

Return unused material to its original container. Wash the spreader thoroughly after each use. Remove the gear cover halves and wash the gears thoroughly. See Figure 2. Then dry completely in the sun or a heated area. Lubrication a. Oil should be applied to the impeller shaft bearing in the hopper, (Figure 2) slide points on the shut-off plate, and the spring in the housing behind the control plate, (Figure ) and the bearing surfaces in the gear assembly. See Figure 4. b. Lightly grease the axle bearings in the frame. See Figure 2. c. Lubricate the face of the gear teeth with dry graphite. Reinstall the gear cover. See Figure 4. Gear mesh should be checked regularly, especially during highuse periods. The clearance between the axle gears and the pinion gears should be very close, but not tight. If adjustment is required: a. Loosen the axle collar set screw and hold the gears together. b. Slide the axle against the gear support, then tighten the axle collar set screw. c. Spin the drive wheel to make sure the gears run freely and smoothly. Periodically clean the surface of the impeller to remove buildup of material. A buildup could cause the spread pattern to change. Maintain tire pressure at 20 25 psi. Figure 2 Figure Dry Graphite Figure 4 Grease Oil: Slide points on the shut-off plate, and the spring in the housing behind the control plate.

Spreader Settings Calibration Instructions 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 000 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 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 Space for wheel track Direction of Operation 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:. 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 Discharge Chute Setting Indicator Application Rate Calculate application rate as follows:. Determine the Effective Pattern Width. See the previous page. For example: Effective Pattern Width is determined to be 0 feet. 2. Determine the coverage requirement of the material to be spread in pounds per 00 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 00 (add two zeros). For example: According to the label on the container, 25 pounds of material will cover 5000 square feet. Calculate average coverage requirement 25 lbs 5000 000.5 00 0.5 pounds per 00 square feet. Measure out an area of 00 square feet (0 by 0 feet). Weigh out 5 to 20 pounds of material and spread it over the measured 00 square-foot area, applying in 0-foot swaths (0-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. The RS75/RS75s spreader was calibrated at the factory. However, calibration should be checked periodically to ensure best performance.. Pull the control lever to the OFF position and set the rate control plate to setting A. See Figure 0. 2. Put the control lever to the ON position and check the port opening. See Figure. The port should be just opened. If adjustment is necessary, continue to Step.. 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. Pointer Rate Control Plate Rate Control Knob Figure 0 View Inside Hopper Port Just Open Space pans foot on centers Knob Knob Impeller Figure 8 Figure 9 Figure 8 9
