is a good practice to not use the very end gate as one of the 4
because it is typically open slightly more to make the edge of the
mat more consistent.
F. Back the chipper up about 200’ from the tarp. Drive a practice
run towards the tarp at a speed that feels comfortable to chip. In
most cases you need to be at about 300 fpm+. It is very critical
that you not change speed while covering the tarp. Drive over the
tarp holding the speed then stop afterwards. If everything seems
ok back up about 100’ and drive towards the tarp again. It is im-
perative that you back up far enough so that you can see the tarp
over the top of the spread hopper. This will give enough time for
you to even the speed and the cam can to adjust to that speed a
few seconds before reaching the tarp. Turn on the 4 gates about
2’ in front of the tarp and off about 2’ after the tarp. Again, it is
very critical you not change speed while spreading over the tarp.
G. If the tarp is completely covered, carefully find the edges and pick
up the corners in a manner that doesn’t loose any chips. Hang
the tarp from the scale and read the weight.
H. If the actual spread rate is more than 3 pounds different than
desired, on the display push the right arrow to access the Calibra-
tion page. Press the #1 button to highlight the pan weight. Use
the up/down arrows to enter the weight correction. Ex. If the tarp
weight (pan weight)
was 4lbs heavy then
enter -4 to correct and
press OK. Ex. If the
tarp weight was 10 lbs
light then enter 10 to
correct and press OK.
I. Run the calibration
procedure again to
check. It is not un-
common to make a
few adjustments before you get it right.
J. The Right spread hopper is controlled with the hopper balance.
The hopper balance allows you to increase or decrease the rate
on the right side for a total of + or - 10%. It is best you make this
adjustment visually while chipping. The balance display works in
