Dirt hopper/
suction turbine
The suction turbine, driven by a
hydraulic motor, is located in the top
area of the dirt hopper. It spins at
approx. 3,000 rpm. The suction tur-
bine needs to be cleaned every day. To
avoid poor suction pressure,
inspect and clean seals at rear flap
and suction duct every day. Replace
worn seals. For more details about
daily cleaning routine refer to page 59
"cleaning after sweeping".

Service brake

The Hako-Citymaster 1800 TDI uses a
dual circuit hydraulic service brake on
all 4 wheels. The are actuated by a
brake pedal. Brake action of the rear
wheels is load-controlled. Break fluid
container is located on the rear wall of
the cabin. Fill level must read between
both marks and has to be checked at
daily intervals. Add fluid as required
and check for the reason of a fluid
loss. Fill capacity is approx. 0.5 litres.
Note: Change brake fluid every 2
years.
