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 125lbs 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
situation 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.

Step 2: Assembling the Support Leg
1. Position the support leg so the J-shaped end is pointing away from the wheel assembly.
2. Insert the M8x75 hex bolt through the top hole on the support leg and slide the spacer over the bolt
end.
3. Take the support leg and insert the bolt through the upper cross bar on the mounting assembly
and loosely tighten with the M8 lock nut.

holes line up.
4. Insert M6 x 40 hex bolt through the holes in the flange and cross bar. Use the Ø6 big flat washer
and M6 lock nut and tighten all hardware.

10
STEP 3: Installing the Hopper
1. Lower the hopper over the mounting assembly, carefully line up the holes in the bottom of the
hopper with the spindle in the mounting plate of the axle.
2. Use the M6 x 40 hex bolt and Ø6 flat washer to attach the hopper to the mounting assembly and
secure with M6 lock nut.
3. Make sure the gear and pinion gear works smoothly. If not, adjust again until the gear and pinion
gear swivel smoothly.
4. Tighten all the hardware on the shaft support plate and hopper.
5. Insert the R pin through the top of the spindle.

11
STEP 4: Connecting Handle to the Support Leg
1. Slide the handle tube into the top of the support leg and align the two holes.
2. Insert M6x35 hex bots through the two holes on the support leg and tighten with the Ø6 spring
washer and M6 lock nut.
3. Insert M6x20 hex bolt through the hole in the side plate and tighten with Ø6 spring washer and M6
lock nut.

12
STEP 5: Connecting the Solid Linkage
1. Connect the solid linkage through the bottom fix plate using the Ø8 flat washer and tighten with a
M8 lock nut.
2. Connect the other end of the linkage to the flow control with an Ø8 flat washer and M8 lock nut.
3. Install the hopper screen in the bottom of the hopper.
4. Before using the spreader make sure all the hardware is tightened.
5. Use the rain cover as needed to protect material in the hopper or when spreader is being stored.

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 speedsand 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.
Operation Instructions

14
ADJUSTING THE FLOW
1. You can move up the handle to adjust the spreader setting by following the direction of the
arrowhead. When then handle moves up to “30”, the adjustable plate is fully open, when it goes to
“0”, it’s fully closed.
2. Loosen the wing nut on the Bracket and move the adjustment lever handle up or down depending
on the amount of material required. Pushing the handle down will release more material and
pulling the handle up will stop the flow entirely.
3. Tighten the wing nut when the desired position is reached.
Operation Instructions

15
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.
Operation Instructions

16
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 8).

•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.
•Never exceed load capacity rating of 125lbs it will damage the spreader.
IMPORTANT:
If a part needs replacement, only use parts that meet the manufacturer’s specifications. Replacement
parts that do not meet specifications may result in a safety hazard or poor operation.
STORAGE
•Never allow material to remain in the hopper for extended periods of time.
•Before storing make sure the spreader is clean and dry for years of trouble free service.
•Store indoors or protected area during severe weather and winter months.
