Adapter for filling the water tank in the Operator's cab.
The water tank has a capacity of 50 liters. The filling line
of the water tank is equipped with a drain cock. Before
filling the water tank, drain the old water by opening this
drain cock. Close the drain cock and fill in 50 liters of
clear water. The tank can also be filled through a filler
opening in the Operator's cab.
NOTICE
If freezing temperatures are expected, drain the water from
the filling line by opening the drain cock. Switch on the
engine-independent auxiliary cab heater during standstill
periods to prevent freezing of the water in the cab water tank.
DO NOT drink the water from the water-tap in the
Operator's cab.
Use for hand washing only.
REMARK
The overflow line of the hand wash sink and water tank must
not be obstructed. The overflow line is routed inside the cab base
through a hole in the base floor to the outside. Excess water will
flow through this line to the outside just below the cab base.
