11.3.3 Cleaning the cooling system
For safety and noise considerations, the mechanical
centre of the machine has been fully enclosed by large
safety guards. Many mechanical components produce
heat due to their operation (engines, hydraulics, belts,
blade shafts, etc.). This heat must be able to be removed
from the space inside the shielding panels. Cooling is re-
quired and for this reason it is important that there is a
good fl ow of fresh cooling air brought in throughout the
machine. See the cooling air fl ow in the following fi gure.
Verify that the air fi lter intake is free from obstruction.
See the cooling air fl ow in the following fi gure.
• Verify that the cooling air suction intake is free from obstruction.
(1)
• Verify that the black air box fi ts in properly with the engine so that
the cooling air is not mixed with hot air.
(2)
• Always clean debris from engine cooling fi ns.
(3)
• Verify that the hot air outlets are free from obstruction.
(4)
• Verify that there is no accumulation of chipping residue that can prevent
the cooling of the structure and the hydraulic components.
11.4 Engine maintenance
11.4.1 Checking the oil level in the engine cra refi lling the engine oil
11.4.1.1 Checking the oil level
If a serious shortage of oil occurs in the engine, the electronics on the machine will switch to the
safety mode and the engine will automatically switch off. It follows, that the machine has been
working with a faulty lubrication for a long period of time. Regularly checking the oil level is es-
sential to ensure this situation is avoided.
