CALIBRATION INSTRUCTIONS:
Loosen set-screw on Calibration
Bracket
Set adjustment dial to “0” Closed
Activate switch to extend to the
“STOP”
Slide Calibration Bracket to
ensure shut-off is closed
Calibration is now complete
To Calculate RATE SETTINGS:
Determine how much material is to be applied
per 1,000 sq./ft.
Measure off a distance of 50 feet, preferably on a paved surface such as a parking lot.
Weigh out enough of the material to be applied to fill the hopper at least half full. Record the weight for
future use.
With the unit mounted on the vehicle and the hopper at least half full of the material to be spread, posi-
tion the vehicle far enough before the beginning of the 50 foot test area so that the vehicle will achieve the
desired speed before you reach the starting line.
Select the Setting Rate position that you feel would be an appropriate setting on the ECM Module 1-10.
IMPORTANT - only make Rate Adjustments with the shut-off in the CLOSED POSITION
Start the vehicle in motion and as you cross the starting line (of the
50 feet) move the rate lever to the open position against the stop.
Take care to be aware of what is going on around you maintaining
control of the vehicle.
Continue from the starting line with the unit spreading the material.
As you cross the finish line move the rate lever to the closed posi-
tion.
Stop the vehicle and note the width of the spread path that was just
completed.
Return to the start point and empty the remaining material from
the hopper into your weighing container and re-weigh.
OPERATING INSTRUCTIONS:
Before filling hopper, become familiar with the operation of this
spreader.
(Practice the following steps)
Turn the motor switch to the ON POSITION, so that the impeller is
turning before going on to the next step.
While driving forward turn the ECM Control switch (wide top switch) to the ON POSITION, this opens the
shut off plate on the spreader.
To stop the flow of material, turn the ECM Control switch to the OFF POSITION, then turn the motor off
when finished.
When finished empty any remaining material from hopper.
Thoroughly wash spreader and allow to dry before storing. Lubricate all moving parts with a graphite or
silicon spray.

To Calibrate loosen set screw
slide Calibration Bracket
Install Calibration Bracket to ECM
shaft by sliding the Calibration Bracket
on to the ECM shaft.
M80 Side
M40 Side
To install Calibration Bracket you must
determine which leg corresponds to your
spreader. Short for M40, and long
for M80
Install Control Rod on to Shut-Off from
the top down and secure with small Hair Pin Clip.
Then attach the other end of the Control Rod to the
Calibration Bracket from the bottom up.
Tip:
You may need to retract ECM to fully
closed “0” to aid in installing the Calibration
