Radiator
Winter road service operations
The
fan sucks in snow particles, salt and dust.
This mixture accumulates in the radiators and
condenses if cleaning is neglected.
To avoid impaired cooling and engine per-
formance, all radiators must be cleaned once
a day. Impaired cooling and engine perform-
ance can result in the vehicle breaking down.
In the case of compacted dirt:
X
Flush the radiator fins with lukewarm tap
water.
In the case of stubborn deposits:
X
Carefully clean the radiator with a high-
pressure
cleaner; see the vehicle's Operat-
ing Instructions.
!
Only
direct the compressed-air, steam or
water jet towards the radiator surface in a
vertical direction. Ensure that the radiator
fins
are not damaged. Remove any dirt from
the radiator fins. Damaged or dirty radiator
fins can cause the engine to overheat. If
there is a loss of coolant or damage to the
cooling and heating system, have it
checked at a qualified specialist workshop.
After every extreme winter road service oper-
ation:
X
Check the radiator (visual inspection).
Summer operation
Clean the radiator every day in the case of
heavy soiling during mowing operation.
X
Remove grass and plant cuttings.
X
Clean the radiator fins using compressed
air.
Cab interior
Cab floor
When
getting in, snow, dirt and salt will inevi-
tably be carried into the cab interior. This cor-
rosive mixture accumulates in the footwell
area and promotes corrosion of the electrical
and other components in the interior.
i
Mercedes-Benz recommends that you
use floormats. Floormats can be removed
and cleaned if dirty or wet. This prevents
damage to the cab floor from residual
dampness.
X
Regularly remove and clean the floor cov-
ers.
X
Clean the cab floor.
X
Dry off moist residue immediately.
X
In case of dry dust and salt residue: vacuum
and clean the cab interior, particularly in
the corners and pedals.
