Using the cable and handle provided at the left side inspection door, open the separa-
tor door and lock in the second cable bead position. Step the dump door closed as when
opening. Failure to open the separator door when washing out the hopper can cause de-
bris to collect in the separator chamber, inhibiting the separator to spin out dust, there-
fore causing rapid wear of the blower housing components.
After using the hopper deluge system, a hand held high volume/high pressure hose
should be used to remove any debris left by the hopper deluge.
B. DST-6 COMPONENTS
Uncouple the suction transition and using
the hand held wash hose, wash out the
suction tube leading from the pick-up head
to the hopper inlet. The vacuator manifold
rock screen must also be washed clean.
Remove the cleanout plugs from the vac-
uator bin and the scavenge hose cleanout
tee (Photo M01378). Back flush the vac-
uator hose and scavenge hose observing
water running out the cleanout ports. Close
the vacuator manifold ball valve once the
vacuator hose has been washed out. (Pho-
tos M01369 & M01370)
Remove the pre-filter panel from the DST-6
box and thoroughly clean making certain
to remove all dirt and grass debris from the
small tubes on the panel face. Clean out
the scavenge bin which is the area in the
DST-6 box just under the pre-filter. The
scavenge hose must be flushed out and
clear before reinstalling pre-cleaner. (Photo

C. DST-6 FILTERS
The DST-6 uses special filters to clean the
exhaust air before it is released into the
atmosphere. The filters utilize a PTFE mem-
brane which gives the filter good release
characteristics as well as protection from
water damage. The filters are actually wa-
terproof and can be washed by low pres-
sure hose and returned to the sweeper with-
out drying. Should mud dry on the filters,
soak the filter until the mud softens, then
wash off with low pressure water hose.

The filter PTFE membrane is fragile and
over-servicing the filter can cause the PTFE
membrane to fail. Care should always be
used when handling the filter as the PTFE
