5.2. Maintenance every 8 - 15
operating hours
5.2.1. Checking engine oil level
To check the oil level, the engine must be
standing level and be switched off.
– Remove any dirt from the oil dipstick area.
– Remove dipstick and clean it.
– To check the oil, screw the dipstick back in
and then remove it again, Fig. 7.
– Check the dipstick oil level and, if necessary,
add oil to the max. mark, Chapter 4.1.1.
5.2.2 Check air intake area for
combustion and cooling
Heavy contamination is an indication that in-
creased dust accumulation necessitates a corre-
spondingly shorter maintenance interval,
Chapter 5.3.1., 5.3.4. and 5.4.2.
– Check air intake points for severe blockage
due to leaves, heavy dust accumulation etc.,
and if necessary clean them, Fig. 23.
On version with oilbath air cleaner, also check
air intake area „2“, Fig. 28.
5.2.3. Check air cleaner maintenance
indicator (optional extra)
Mechanical service indicator
– Increase the speed of the engine briefly to the
maximum.
If the rubber bellows shrinks and covers the
green area „1“, the air cleaner system should
be serviced, Figure 24, Chapter 5.4.2.
Under dusty conditions, check the rubber bel-
lows several times per day.
5.2.4. Checking the water trap
The intervals at which you should check the
water trap depend entirely on the amount of
water in the fuel and the care taken when re-
fuelling. The normal interval is once a week.
– Loosen hexagon screw „1“ with approx.
3-4 rotations; Fig. 25.
– Trap the drops which emerge in a transparent
vessel. Since water has a greater specific grav-
ity than diesel fuel, the water emerges before
the diesel fuel. The two substances separate at
a clearly visible line.
– As soon as diesel only emerges at screw „1“,
this can be tightened again.
If an external water trap is attached, check its
water content every day, when the engine oil
level is checked. The water which has collected
is separated at a clearly visible line from the
diesel fuel above it.
– Open drain plug „1“ and drain the water out
into a suitable vessel; Fig. 26.
– If the drain plug is difficult to reach, an exten-
sion hose can be attached to it.
