7 Maintenance and care
68 TW85
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 has been used for the first time, or
when newly painted, to ensure that the paint
can harden sufficiently.
•
Do not use aggressive detergents to clean 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.) should 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.
•
When cleaning the engine with water or steam
jets, do not expose sensitive engine parts, such
as generator, cabling, oil pressure switches,
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 manual 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. -25°C.
Condition of the battery
•
A good cold start performance requires a well-
charged battery. By warming the battery to
approx. +20° (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!
