Hazard Signal Word Definitions
ABOUT YOUR PUSH SPREADER
This push spreader is designed to spread a wide range of materials (Fertilizer, Grass Seed and Ice melt).
Materials such as Powders, Manure, Top Soil, Gravel, and Mulch have the wrong physical characteristics
and should not be used with this spreader.Never exceed the rated load capacity of 90lbs when
operating the spreader.
Your spreader needs to be pushed at three miles per hour, which is a brisk walking speed. Slower or faster
speeds will change the spread patterns. Wet spreading material will also change the spread pattern and
flow rate. Clean your spreader thoroughly after each use. Wash between the shut off plate and bottom of
the hopper.
Technical specifications on the push spreader are provided in the “Specifications” section of this manual.
This is the safety alert symbol. It is used to alert
you to potential personal injury hazards. Obey all
safety messages that follow this symbol to avoid
possible injury or death.
DANGER indicates an imminently hazardous
situation which, if not avoided, will result in death
or serious injury.
DANGER
WARNING indicates a potentially hazardous
si
tuation which, if not avoided, could result in
death or serious injury.
WARNING
CAUTION indicates a potentially hazardous
situation which, if not avoided, may result in minor
or moderate injury.
CAUTION
CAUTION used without the safety alert symbol
indicates a potentially hazardous situation which,
if not avoided, may result in property damage.

WARNING
Before using the push spreader, review the instructions below and safety information. Failure to
follow these instructions may result in property damage or injury to the operator or bystanders.
USING YOUR SPREADER
1. Inspect your spreader before each use. Make sure the wheels turn easily, and the gearbox moves
when the spreader is pushed. The hopper should be clean and free from cracks.
2. Spreader is designed to spread a range of materials (Fertilizer, Grass Seed and Ice melt).
Materials such as Powder, Manure, Top Soil, Gravel, and Mulch have the wrong physical
characteristics and should not be used with your spreader
3. Do not use spreader on windy days when spreading grass seed or herbicides.
4. Determine approximate square footage of the area to be covered and estimate amount of material
required. Please refer to fertilizer manufacturer’s recommendation. Break up any lumpy fertilizer
as you fill the hopper.
5. Before filling the hopper, make sure that the flow control lever is in the“0”position and the flow
control plate is closed.
6. Set the adjustable stop with the flow control lever always in the“0”position. Every time you are
ready to stop or turn back, close the flow control plate to stop dispersing the material and continue
one more stride. This reduces waste and avoids damaging the lawn with oversaturated product
coverage.
7. Follow fertilizer manufacturer’s recommended coverage rate for each product
8. To maintain the same coverage when walking at a different speed, adjust the flow rate. Reduce the
flow setting for slower speeds and increase the flow setting for higher speeds.
9. Keep the impeller plate horizontal when operating the spreader. Tilting the spreader will result in
uneven coverage.
10. Make sure the R pin is installed in the hopper before starting the spreader.
11. Always start walking prior to opening the closure plate.
12. Always close the flow control plate before turning or stopping the spreader.
13. If spreading material is accidentally deposited too heavily in a small area, soak the area thoroughly
with a garden hose or sprinkler to prevent burning of the lawn.
14. To insure consistent coverage, make sure each broadcast pattern slightly overlaps the previous
broadcast pattern.
15. When broadcasting spreading material, make sure the broadcast pattern does not hit evergreen
trees, flowers or shrubs.
16. Do not over apply spreading material. Follow the recommended coverage rate for each product.
Over application will lead to lawn damage and contamination.

ADJUSTING THE FLOW
CONSISTENT COVERAGE
To insure consistent coverage, make sure each broadcast pattern slightly overlaps the previous broadcast
pattern as shown in figure below. The approximate broadcast widths for different materials are shown in
the application chart.
WARNING
Do not over apply spreading material. Follow the recommended coverage rate for each product.
Over application will lead to damage and contamination. If spreading material accidentally hits or
deposits too heavily, soak the area thoroughly with a garden hose or sprinkler to prevent burning.
CAUTION
The spreader settings are guidelines only. The spreader should be calibrated prior to application to
ensure accuracy.
If you have a Push Spreader or Tow Spreader the settings are based on a walking speed of under
3MPH or towing speed of 5MPH. Walking or towing faster or slower will alter the spread application
rate. Exact rates depend upon the spreader itself and the accuracy of the equipment operating it.

CALCULATING AMOUNT OF MATERIAL NEEDED
To calculate the amount of fertilizer you will need to cover your lawn, divide the coverage amount listed on
the label by the weight of the fertilizer bag. For example a 10LB. bag of fertilizer with coverage of 10,000
square feet will distribute 1LB. of fertilizer every 1,000 square feet at full rate or 1/2LB. of fertilizer every
1,000 square feet at half rate. For pre-calculated rates see Chart A (Example: 25LB. bag with 15,000 sq. ft.
coverage = 1.7LB./1,000 sq. ft.). Use Chart B to find the closest spreader setting (Example: 1.7LB./1000
sq. ft. = Spreader Setting of 2).

ADDITIONAL SPREADER SETTING INSTRUCTIONS
For materials that DO NOT use a typical 5,000 Sq. Ft, 10,000 Sq. Ft. & 15,000 Sq. Ft. coverage value.
To obtain the proper spreader settings follow the steps below:
1) Find the total weight in lbs. of the product from the product label on the bag of material.
2) Find the coverage amount in square feet that the product is rated for from the product label on the
bag of material.
3) Divide the bag weight rated in lbs. by the square feet coverage rated on the bag.
4) Take this result and multiply it by 1000.
5) This final number is the lbs. of material to be spread per 1000 square feet.
6) Use the spreader setting number in Chart B for the proper setting.
As an example:
1) The fertilizer bag weighs 10 lbs.
2) The coverage value is rated at 2000 square feet.
3) 10 lbs. / 2000 square ft. = 0.005
4) 0.005 × 1000 = 5 lbs. per 1000 sq. ft.
5) Using this number in Chart B, you would obtain a spreader setting of 2.

WARNING
Improper maintenance and storage of the push spreader may void your warranty.
MAINTENANCE
•After each use clean material out of hopper and off of the impeller.
•Rinse/dry inside and outside of the spreader after each use.
•Before operating make sure the tires have the RECOMMENDED TIRE PRESSURE 20 PSI.
•Periodically check all fasteners for tightness.
•Annually clean and lightly lubricate parts.
•Use a glossy enamel spray paint to touch up scratched or worn painted metal surfaces.
