Rules for greasing and oiling
• Grease the bearing spaces on the casing of the overrunning
system.
• Oil movable parts such as bolts and joints.
• Grease the movable parts of the overrun coupling.
• Check to see that the stationary parts of the shearing rod are
not jammed.
• Clean and oil all movable and stationary parts at regular intervals.
For safety reasons, the spare parts for heating devices
must conform with the manufacturer's instructions. They
must be installed by the manufacturer or an authorised
representative.
11.2 Ventilation Sucient ventilation and de-aeration of the vehicle interior is es-
sential to maintaining a comfortable climate.
The oxygen in the vehicle interior is used up by passen-
gers’ breathing and the operation of gas-fuelled devices.
It must thus continuously be replaced. Forced ventilati-
on systems (e.g. roof bonnets with forced ventilation;
mushroom fans or oor vents) have been tted in the
vehicle for this purpose. Forced ventilation systems may
not be covered or blocked, either from the inside or from
the outside. They must always be kept free of snow and
leaves. Increased CO2 levels can result in suocation.
Using only the forced ventilation systems as the sole source of
ventilation for the vehicle interior is, however, never sucient.
Correct ventilation is thus just as important as correct heating.
Moisture can occur anywhere in the interior – for example as result
of showering, cooking, drying washing or simply passengers’ per-
spiration.
Correct ventilation means regular ventilation – at least two to four
times a day for 5-10 minutes each time. Moisture occurs in all living
areas. Up to 12 litres of water can accumulate each day in a four-
person household and this moisture must be disposed of by means
of correct ventilation. Failure to do so will result in the moisture
collecting in the coldest areas as condensation. This is the basis for
mould, particularly in winter. A correct amount of fresh air is required
to maintain a healthy, pleasant indoor climate.
Cross-ventilation of rooms is a particularly eective way of replacing
air. Simultaneously fully open several windows; the door; the roof
bonnets and, where applicable, the room dividers several times a
day for several minutes. This will result in an air current which draws
moisture from the inside of the caravan to the outside.
In contrast, permanent ventilation by means of windows which are
only tilted or slightly opened is absolutely incorrect as the exchange
of air is minimal and insucient.
CHECK LIST:
üVentilate the caravan regularly!
At least twice a day for 5 – 10
minutes each time
üAlways open windows fully
when ventilating;
cross-ventilation is best
üDo not ventilate for long periods,
instead ventilate often
üAlways wipe away condensation
immediately
üEnsure that forced ventilation
systems are never obstructed
