5.2 Maintenance every
8 – 15
hours
of operation
5.2.1. Check engine oil level
When checking the oil level, the engine should
be standing level, and must not be running.
– Check oil level at the dipstick. Add oil up to
the MAX mark on dipstick „1“ if necessary
(Figure 8, Chapter 4.1.1.).
5.2.2. Check combustion air intake area
Severe contamination is a sign that the air con-
tains a high level of dust, and that the mainte-
nance intervals should be shortened accordingly
(Chapter 5.4.2.).
– Inspect intake opening „1“ on the rain protec-
tion cap or cyclone separator for severe block-
age with dirt, for instance leaves, heavy dust
deposits etc., and clean if necessary.
(Figures 18 and 19).
– Check for free airflow at dust outlet hole „2“
on the underside of the housing, and clean if
necessary (Picture 18).
With oily contamination remove cyclone and
clean it.
– Run the engine at full speed briefly once a day,
shortly after starting it. Check that indicator
light „5“ comes on briefly or, depending on
version, red zone „1“ is seen in the mechanical
maintenance indicator (Figures 13 and 20,
Chapter 5.4.2.).
5.2.3. Check the cooling air system
Severe contamination with dirt is a sign that the
air contains a high level of dust, and that the
maintenance intervals should be shortened
accordingly.
– Inspect the air inlet and outlet areas for severe
blockage with dirt, for instance leaves, heavy
dust deposits etc., and clean if necessary
(see Chapter 5.3.2.).
Temperature display „4“ (if fitted) lights up as
soon as the engine starts to overheat (Fig.13).
Stop the engine immediately. (Chap. 5.3.2.).
5.3. Maintenance every
250
hours
of operation
5.3.1. Engine oil change
(see Chapter 5.1.)
The dipstick mark will indicate whether or not
the engine has a sump (see Chapter 4.1.1.).
The engine must be stopped, and should be
standing on a flat, level surface.
– Drain the engine oil only when it is warm.
Risk of scalding from hot oil.
Trap the old oil and dispose of it in an
environmentally acceptable manner.
– Unscrew oil drain plugs „1“ and allow all the
oil to drain out (Figure 21).
– Attach a new seal and insert and tighten the oil
drain plug.
