7 Care and Maintenance

7.6 Care and cleaning
The machine must be cleaned on a
suitable surface with an oil separator.
• Neither a steam-jet appliance nor a high-
pressure cleaning apparatus may be used for
cleaning during the first two months after the
machine is used for the first time or when newly
painted to ensure that the paint can sufficiently
harden.
• Do not use aggressive detergents for cleaning
the machine. We recommend using
commercially available cleaning agents for
passenger cars.
• When cleaning with a steam-jet appliance, the
hot water jet should not exceed 80°C and a
spray pressure of 70 bar.
• Linings (insulating materials, etc.) shall not be
exposed directly to water, steam or high-
pressure jets.
• When cleaning with water or steam jets, take
care not to spray exhaust-gas and air filter
openings.
• If cleaning the engine with water or steam jets,
do not expose sensitive engine parts, such as
generator, cabling, oil pressure switch, etc.
directly to the jet.
• After each wet clean, the machine must be
lubricated in accordance with the lubricating
plan and a test of all work cycles, support and
driving functions carried out.
7.7 Notes for winter operation
The following points - and the relevant notes in the
engine instruction book - should be observed
during winter operation.
Hydraulic oil
• If the machine is not used for longer periods at
temperatures around and below freezing, warm
up the engine by running at medium revs (for
approx. 3-5 min).
Engine oil
• The oil viscosity (SAE class) should be selected
according to the ambient temperature at the
machine’s place of operation.
Coolant
• Before the beginning of the cold season, check
the level of antifreeze and adjust in line with the
ambient temperature if necessary.
• At the factory, the antifreeze protection is set to
approx. -40°C.
Battery charge
• A good cold start performance requires a well-
charged battery. By warming the battery to
approx. +20°C (remove the battery after the
engine has been turned off and store it in a
warm room), the minimum starting
temperatures can be lowered by 4-5°C.
• When installing the battery, ensure good
contact of terminal connections.
• Only tighten terminal screws so that they are
"hand-tight", to prevent deformation of the
terminal cones!
Fuel
• Only use commercially available brand-name
diesel fuel with a sulfur content of less than 0.5 %.
• Use only winter diesel fuel in winter, in order to
prevent cables becoming blocked through
paraffin deposits. At very low temperatures,
troublesome deposits may also occur when
winter diesel is used.
