1 full-way valve
2 control lever, fine-mesh screen
Note:
all of the nozzles and the
strainer should be inspected for clean
condition once a day, as well as
screens in the overflow hoses of the
freshwater tank. The Hako-Citymaster
uses water recycling system.
Recirculating water tank is located on
the RH side behind the cabin, under-
neath the hopper. Tank capacity is
approx. 60 litres.
Water spray system
The Hako Citymaster 1800 TDI uses a
380 litres fresh water tank located in
the bottom area of the dirt hopper and
extending into the side walls. Filling
points use "D"-fittings and are located
on both sides of the hopper.
Note :
water may be supplied from the
public water supply net through a "D"-
fitting only. The electric water pump is
located on a structural member on the
RH end of the machine,
its supply pressure is 4 bar. Spray
nozzles are arranged at the forward
brushes so that the water is directed
against the brush, binds dust and
spreads water over the area in front of
the brush.
One more nozzle is located in the suc-
tion duct inlet to wetten the suction
duct. All of these nozzle are controlled
independent of each other and may be
adjusted as required for a particular
mission. Water control valves are
arranged on the central control panel
in the cabin. Water supply should be
adjusted as to allow the machine to
work dust-free.
Note:
to allow extended dust-free
sweeping, we recommend to fill
approx. 100 litres of water in the dirt
hopper before commencing the mis-
sion. When lifting the hopper, connec-
tion with the recircu-lating tank will be
closed by a two-way valve located on
the right of the hopper. Recirculating
tank, fine-mesh screen, hopper and
full-way valve have to be cleaned
once a day!
For more details refer to page 59 "cle-
aning work".
Before performing such cleaning work,
lift hopper. The full-way valve (VIII/1)
and lever (VIII/2) to open the screen
are located underneath the hopper.
