5.3.4 Cleaning the generating set
To ensure it continues to run correctly, the unit must be cleaned regularly. If the unit is installed inside, always check that the
installation is clean and in good condition. If the unit is being used outside (building sites, dusty, muddy or densely wooded areas,
corrosive environment, etc.), it must be cleaned more frequently.
Use of water sprays or high pressure cleaning equipment is prohibited as this may seriously damage the unit.

spirit or equivalent) and wiped off using a soft, absorbent cloth.
3. Check the general condition of the unit (no leakage, tightness of nuts and bolts, connections and hoses, etc.)
4. Apply an anti-rust product to damaged areas, change defective parts and damaged labels if necessary.
Only use original parts and consult an agent if necessary.
6.1 Transport and handling conditions
The unit should be handled gently and sudden movements should be avoided. Ensure that the place where it is to be stored or
used is carefully prepared beforehand. Before any fixed installation on a trailer or inside a vehicle, consult one of our approved
agents.
Before transporting the unit, take the following necessary precautions:
1. Check that the routes to be used are smooth and drivable. If it proves necessary to use uneven roads, drain the fuel into a
container before setting off.
