R-1 AGGREGATE CHIP SPREADER
OPERATION
When preparing for the daily spreading operation a quick inspection of the
spreader is suggested.
Be sure the
truck hitch
draw bar is
in the set of
holes
closest to
14-1/2 inches from the ground. Back the truck up to the spreader. Adjust the
height of the spreader hitch by means of the jack crank located on the LH end
panel of the spreader. Open the jaws of the hitch with the trip lever. Using the
trip lever and the tilting bars, guide the spreader hitch as the truck makes contact.
Be sure both hitch jaws are locked over the drawbar.
It will be noted in operation that a slight forward rake to the spreader hopper is
best. This will keep the spreader balance rollers from scuffing the tack coat or the
finished blanket. Use the hitch jack to obtain a 1-1/2° - 5° rake on the hopper. This
angle may change due to the springs of the tow truck. As the load decreases, the
back of the truck will rise. Find the rake of the spreader that will keep balance
rollers out of contact until the truck is empty.
Install the operator’s platform (if so equipped). Shift transmission into gear, either
forward (back) or reverse (front). Install the block-off plates if the spread width is
to be less than the spreader width. Insert the block-off plates into the slot formed
between the closed feed gate and the rear hopper panel. This is done easiest
when the hopper is empty. Open feed gate to desired depth, each notch is
approximately 1/4". Fill the spreader hopper and proceed to spread. If a shifting
error was made the transmission will snap to neutral, preventing damage to the
drives. Try to avoid excessive shifting errors.
WARNING:
Stand at the end of the spreader hopper to avoid
being crushed between the truck and the spreader.
