installed to allow air to move freely from the hopper into the
blower area. The hopper screens shall be hinged and pinned
to allow easy clean out.

without tilting the hopper.
The hopper shall cover the main water tank of the water
system and will provide easy access to the water system
components.

suction hose and nozzle to have side-way movement for
establishing more suction power at the curb.

located on the lower portion of the rear door, to enable water
