ADJUSTING THE EV-N-SPRED® DUAL PORT SHUT-OFF SYSTEM
3. Next, using the (7) low baking tins position, them in a straight line on 2ft centers
across the spread width as shown at the right.
Adjust the left or right variable throwing ports to EVEN THE SPREAD pattern.
TIP:
For large/heavy materials, close the
LEFT SIDE
(
BLUE
) port slightly before
you start your EV-N-SPRED® test. For small/light materials, open the
LEFT SIDE
(
BLUE
) port fully and close the
RIGHT SIDE
(
RED
) port slightly before you start
your EV-N-SPRED® test. With BOTH ports closed, the spread is only from the center
port, and will give you a 3-4ft spread width in the center of the spreader - great for
medians.
Begin pushing the spreader several feet before the line of tins and at normal walking
speed. Walk along the Center Line, and OPEN the Lever to the STOP 3-4 paces
before the line of tins and continue walking past the tins 1 or 2 paces and CLOSE
the Lever and STOP.
Visually evaluate the material in the baking tins to determine if your spread pattern
is balanced - having the same amount of material in each baking tin.
Empty each tin back into the spreader, adjust the ports and RETEST until you are
satisfied that the coverage is balanced.
ESTABLISH THE SETTING RATE
4. Remove the material from the hopper, and mark the distance that you need to
travel with the spreader to attain the designated coverage area - i.e. 1,000 square
feet using the spread width you determined earlier. Above is a chart to help
determine the distance needed for 1,000 square foot calculation.
Mark the START and END POINTS on the surface required for the test.
Weigh a small amount (10-20lbs/4-9kg) of the material, and add that into to the
spreader. Using the Setting Matrix included with the spreader, estimate a setting
rate based on material manufacturers recommendations and adjust the STOP on
the Gauge to that position.
Now to test, start walking 1-2 paces before the
START LINE
and OPEN the Lever
to the stop and then CLOSE when you cross the END POINT LINE.
Pour the remaining material from the spreader and weigh to calculate the amount
applied over the area. Adjust the Setting Rate to a higher number if you need to
increase the application rate, or to a lower number if you applied too much in the
test.
You may need to repeat this process to acquire the exact rate.
