NOTE: The blower rpm is dependent upon the debris being swept. Lighter debris
does not require as high of a blower rpm as heavier debris. Lower blower rpm
results in less wear on the sweeper.
7. The sweeper is now ready for normal operation. Keep the truck transmission shift lever
in first gear to provide better throttle response. Best sweeping speeds are from 3 to 5
miles (5 to 8 km) per hour; however, curb conditions and street congestion greatly
determine at what speed to sweep.
8. The design of the pick-up head allows it to handle most debris normally encountered in
the curb without special consideration; however, the operator must remember that items
larger than the 12.0” diameter suction tube must either be manually picked up or
maneuvered around to prevent plugging of the suction tube.
9. Light debris such as leaves and paper may have a hard time getting under the front seal
curtain, especially when encountered in large quantities, producing a bulldozed effect in
front of the pick-up head. When encountering such debris, the operator must open the
“pressure bleeder” door by moving the manual “pressure bleeder” handle back to one of
the notched positions. This will increase the vacuum from the suction side of the pick-up
head and lift the front seal curtain up away from the ground. The pressure bleeder
should only be opened when needed and should be left closed when not needed in
order to assure maximum performance in normal debris.
10.Sweepers with the broom assisted head (BAH) give the operator an additional advan-
tage when sweeping roads with heavy caked on debris. To use the pick-up head broom,
locate the toggle switch labeled “broom assist” and shift it to the down position. This
automatically lowers and turns on the broom. No additional cab controls are necessary
for the broom assist as the broom functions automatically once lowered. Rotational
speed of the broom is constant and non-adjustable.
NOTE
: The pick-up head should always be down before turning on the broom assist,
and the broom assist should always be turned off before raising the pick-up
head!!! For maximum longevity of the pick-up head broom, the operator
should use it only when necessary. When not in use, the operator should
always remember to raise the broom assist to prevent it form dragging
against the pavement.
11.When the sweeping operation is nearing completion, raise the gutter broom(s) first and
continue sweeping before turning off the blower. This makes sure all debris thrown into
the street by the gutter broom is picked up before the sweeper is shutdown.
12.Turn off the blower and then raise the pick-up head. Turn off the warning lights. The
operator should change to the left hand or legal driving seat at the first safe opportunity
for the safest transit in the sweeper.
PICK-UP HEAD MUST BE RAISED FOR TRANSIT!
NEVER BACK SWEEPER WITH PICK-UP HEAD LOWERED UNLESS
EQUIPPED WITH OPTIONAL REVERSE PICK-UP HEAD CHAINS!
PICK-UP HEAD CURTAINS
Because high velocity air is used by the pick-up head to remove debris from the pave-
ment, the pick-up head must be sealed by rubber curtains to the pavement. These
rubber curtains will incur wear as the pick-up head is dragged along the pavement and
