HOPPER ASSEMBLY
The TYMCO Model 600 hopper has a volumetric area of 7.3 cubic yards and is subjected to the
most severe working conditions of any area on the sweeper. The worst enemy of the hopper
assembly is CORROSION! To prevent the hopper from rusting, it should be thoroughly washed
at the end of each shift. It should be pointed out that even a small rust-through area on the hop-
per will have dramatic effect on the sweeper’s performance. The hopper is the vessel from
which the blower draws air; thus, creating the vacuum necessary to lift debris from the pave-
ment. Even a small seal leak diminishes this vacuum tremendously.
A. DUMP OPERATION & CLEAN OUT
To dump the hopper, use the following procedures:
1. Back into area for dumping.
NOTE:
Make certain pick-up head is in UP position
before backing sweeper or serious damage could occur.
2. Start sweeper auxiliary engine and let idle.
3. Actuate dump toggle switch located on left side of sweeper just above the left fender
and work hopper door back and forth several times to fully discharge load.
4. Assure that separator door remains closed and latched throughout dumping proce-
dure and prior to returning to sweeping activities. End plates on skimmer hood
should be flush on top of raker plate.
WARNING: Use care when dumping sweeper that no one is between dump
door and hopper when closing dump door!
5. At end of shift, drive sweeper to wash area; open dump door and inspection doors.
Shut off auxiliary engine and open separator door/skimmer hood assembly using
draw cable located at left inspection door. Wash out hopper making certain to
clean the hopper screen, separator, suction hose and bottom of pick-up head.
B. SERVICE
WARNING: Never work in or around hopper with auxiliary engine running.
Always shut engine off before servicing.
Aside from routinely washing out hopper, the hopper assembly requires very little
service.
1.
Separator Assembly
- the separator is a drum-like area found inside the very front
of the hopper. Its function is to rid the airstream of dust particles through use of
centrifugal force rather than filters. (See Page 7) Service separator daily by using
pull cable handle located behind LH inspection door to open separator door and
wash interior of separator chamber.
NOTE
:
Separator door is held in open position by pulling cable stop through key-hole
in retainer bracket and sliding up slot and releasing. (See Page 8)
