Sweeping attachment
The sweeping unit is attached to the
Hako-Citymaster 1800 TDI by a trian-
gular link. Hydraulic cylinders for brush
lifting and the brush drive motors are
supplied through hydraulic hoses.
The hose routed outside carries water
to the spray nozzles. A hydraulic fitting
in the front panel supplies the actuator
for the suction mouth flap.
Sweeping track width and lift arms are
adjusted in the factory. Sweeping track
width with lowered sweeping unit
(without brush pressure) should
amount to:
RH brush
= 11 to 03 o'clock
LH brush
= 09 to 01 o'clock position.
Adjustment work should be performed
by factory-trained personnel only.
Suction mouth
The suction mouth is lowered together
with the sweeping unit. The sealing
strip located on this suction mouth
needs to have an approx. 0.4 inches
(10 mm) ground clearance.
Adjustment is performed by
displacing the three rollers located
under the suction mouth. To maintain
suction power, replace defective seals
(forward flap either). Service rollers
with grease after every 75 hours of
operation, or more frequent, as re-
quired.
