Earthway M80ECM 12-Volt Professional Broadcast Spreader - Manual (Page 4)

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, position 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 from 1 to 11.
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 position.
 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.
