Unpacking
After unpacking unit, inspect carefully for any damage that may
have occurred during transit. Check for loose, missing, or
damaged parts. Shipping damage claim must be filed with carrier.
Read These Instructions Before Assembly
Your spreader is designed 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.
Ensure that the FRONT of the gear box points to the front of the spreader. The impeller must turn clockwise.
Reversing the gear box will cause the impeller to turn counter clockwise. Clean the impeller plate after each use.
Spreading material stuck on the impeller blades will cause uneven spreading.
Gears are permanently lubricated at the factory. Do not open the gear box or dirt may enter.
General Safety Information
Make sure you are appropriately dressed, including
sturdy footwear. Protect yourself by wearing gloves
and a dust mask when handling chemical lawn
products that contain pesticides and herbicides.
Assembly
Before assembling this spreader, you need to have
the following tools:
1. Two 8mm Wrenches
2. Two 10mm Wrenches
3. One Rubber or Wooden Mallet

STEP 1：
1. When assembling the wheels, please keep the
air valves facing outward for easier inflation.
2. Slide one tire (#29) onto Side A of the axle. Align
the hole in the axle with the hole in the wheel,
then insert a M6 x 60 bolt (#36) through both
holes and fasten with lock nut M6 (#25). Attach
axle end cover (#31) by tapping with a wooden or
rubber mallet.
3. Slide the other tire (#29) onto Side B of the axle.
Slip a flat washer Ø 16 (#30) onto the axle next to
the wheel. Attach axle end cover (#31) by tapping
with a wooden or rubber mallet.

STEP 2：
Install upper handle (#42) on support leg. Insert two
bolts M6 x 40 (#24) through upper handle and support
leg. Fasten with lock nuts M6 (#25). Push the control
handle all the way down. The hole in the bottom of the
spreader should be opened completely. If the hole
does not line up exactly, loosen Lock Nut M5 (#21) a
few turns and push the cable until it matches the hole
in the bottom plate exactly. Tighten Lock Nut M5
(#21).

Using Your Spreader
READ ALL STEPS COMPLETELY BEFORE
STARTING
1. Inspect your spreader before each use.
Make sure the wheels turn easily, and the
impeller still moves when the spreader is
pushed. The hopper should be clean and
free from cracks.
2. Determine approximate square footage of
the area to be covered and estimate amount
of material required. Please refer to the
spreader setting instructions on the next
page to obtain the proper spreader setting.
3. Spreader is useful for spreading a range of
materials (Ice Melt, Fertilizer, and Grass
Seed). Materials such as Powder, Manure,
Top Soil, Gravel, and Mulch have the wrong
physical characteristics and should not be
used with these spreaders.
4. Before filling the hopper, make sure that the
flow control lever is in the “0” position and
the flow control plate is closed.
5. Make sure the R pin is installed in the
hopper before using the spreader.
6. Break up any lumpy fertilizer as you fill the
hopper.
7. Once you have determined your proper
spreader setting and are using the spreader,
keep the following thoughts in mind to
optimize spreading results: Always set the
adjustable stop with the flow control to the
“0” position and continue moving one more
stride whenever you are about to stop or turn
the spreader. This action will close the flow
control plate and stop the dispersing of
material, which will result in reduced waste
and avoid damaging the lawn with
oversaturated material.
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. Always start walking prior to opening the flow
control closure plate.
11. 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.
12. To insure consistent coverage, make sure
each scatter pattern slightly overlaps the
previous scatter pattern as shown in figure
below. The approximate scatter widths for
different materials are shown on Chart B.
13. When scattering spreading material, make
sure the scatter pattern does not hit
evergreen trees, flowers or shrubs.
14. Make sure you are appropriately dressed,
including sturdy footwear. Protect yourself by
wearing gloves and a dust mask when
handling chemical lawn products that contain
pesticides and herbicides.
15. Do not over apply spreading material. Follow
the recommended coverage rate for each
product. Over application will lead to lawn
damage and contamination.

COVERAGE VALUE
See additional spreader setting instructions on the
following page if your material coverage value is not
typical.
To obtain the proper spreader setting for the
material being spread, follow these steps:
1) Find the total weight in lbs. of the product
from the product label on the bag of
material. Reference the nearest
corresponding row in Chart A.
2) Find the coverage amount in square feet
that the product is rated for from the
product label on the bag of material.
Reference the corresponding column in
Chart A.
3) Find the nearest intersecting point of these
two numbers from Chart A. (this number
equals the lbs. per 1000 sq. ft.)
4) Use this number to find the nearest
number in the column “lbs. / 1000 sq. ft.”
on Chart B to obtain the spreader setting.
5) You may have to approximate your
spreader setting based upon the lbs. per
1000 sq. ft. number that you arrived at.
As an example:
1. The fertilizer bag weighs 42 lbs.
2. The coverage value is rated at 15,000
square feet.
3. Use Chart A to find the corresponding
column of coverage and nearest row of
weight. The nearest intersecting point is
approximately 2.8 since the bag weight is
between 40 lbs. and 45 lbs.
4. Using Chart B, the number 2.8 is between
2 lbs. per 1000 sq. ft. and 3 lbs. per 1000
sq. ft.
5. Spreader setting would be 7.

COVERAGE VALUE
To obtain the proper spreader setting for the
material being spread, follow these steps:
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 this number in Chart B to obtain the
proper spreader 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 12.
