Selector valve
shift valve (V/2) arm down
= loosen parking brake
to loosen parking brake actuate
manual pump (V/1); to amplify
pumping action plug scraper tool on
pump lever. This scraper tool is
located in the rear of the machine.
Continue pumping until you feel
counteraction and RED pilot light for
the parking brake dims.
Actuate bypass valve
Seen in the direction of travel, the
bypass valve is located at the left
behind the fuel tank and is accessible
via an opening of the fairing.
open bypass valve
= spanner (size 9) upwards
close bypass valve
= spanner (size 9) downwards
Note:
to avoid damages at the
hydraulic installations do not tow the
Hako Citymaster 1800 TDI farther than
500m and do not exceed a speed of
5 km/h.
Travel drive assembly
The Hako-Citymaster 1800 TDI uses a
hydrostatic drive system. Traveling
speeds adjust continuously within
the limits of the gear selected. Accele-
rator pedal will return to neutral auto-
matically, thus dynamically decelerat-
ing the machine by the hub motors; if
additional braking power is required,
just actuate the service brake. Travel
drive hydraulics use a closes loop
system. Hydraulic pump is engine-
driven and supplies hub motors in the
rear wheels with pressurized oil.
Towing
Rear wheels are blocked unless the
engine is running. Should your Hako-
matic 1800 TDI once need to be
towed, actuate valve (V/2) to open the
parking brake, then open bypass valve
as described below:
The towing lug is located at the front
of the sweeping attachment.
Caution:
The steering is not fully ope-
rable if the engine if off.

Change hydraulic oil
and filter
First hydraulic oil change after 600
hours of operation., thereafter every
600 hours, but not less than once a
year, even if the specified service hour
parameter has not been attained. Use
hydraulic oil only as approved by the
manufacturer.
In the factory the hydraulic system has
been filled with multi-range oil HVPLP
46, e.g. Mobiloil DTE 15 M.
Biologically degradable
hydraulic oil (option)
e.g. Mobiloil: Mobil EAL
Syndraulic 46 or
Fuchs Plantohyd S. or
Panolin HLP Synth 46
