7.8.5 Oil cooler
The oil cooler is installed on the water tank. It cools
the hydraulic oil for the hydraulic system.
If a front-mounted machine (such as a front-mount
sweeper) is operated as well, an additional oil cooler
is required. This is also located in the same location
on the water tank.
7.9 Pneumatic system
The movements of the cross brush, the disc brush
and the switching of the air flow to blow operation
are all controlled pneumatically. Compressed air is
supplied by the vehicle via a separate compressed
air tank.
