6 Maintenance procedures
6.1 Checking bolts, nuts and screws
To prevent faults or breakdowns, carefully check all the nuts, bolts and screws on a daily basis.
- Inspect the motor pump assembly before & after every start-up and usage.
- Tighten any loose nuts or bolts.
6.2 Renewing the engine oil
To ensure that the oil service is performed quickly and correctly, the oil must be changed when the engine is warm (start the
generating set and allow it to run for a few minutes if necessary).
Observe the environmental protection provisions (see § Provisions for protecting the environment) and drain the oil into a suitable
container.
1. With the engine still warm, place a suitable container under the oil drain screw (B - 1), then remove the oil dipstick/filler
plug (B - 2) and the oil drain screw.
2. After draining completely, refit the oil drain plug.
3. Refill with the recommended oil (see § Specifications) then check the level (see § Checking the oil level).
4. Refit and tighten the oil dipstick/filler plug.
5. After filling, check that there are no oil leaks, and wipe away any traces of oil with a clean cloth.

Cleaning the air filter

Never use petrol or flammable solvents for cleaning the air filter element (risk of fire or explosion).
IMPORTANT
If the filter elements are excessively dirty or damaged (torn, pierced), it is essential to replace them with new elements.
1. Remove the nut and cover from the air filter (D - 1 & D - 2).
2. Remove the wing nut and filter elements (D - 3, D - 5 & D - 4) to clean them.
3. Wash the foam element in a solution of household cleaner and warm water and rinse thoroughly.
OR: Wash the foam element with non-flammable solvent or solvent with a high flash point.
4. Allow the foam element to dry completely then soak it quickly in clean engine oil and remove the excess oil by wringing out
the foam.
If there is too much oil remaining in the foam, the engine will emit smoke when it is first started.
5. Gently tap the paper element several times on a hard surface to remove any excess dirt.
Never try to remove dirt using a brush.
6. Carefully check that both elements are not ripped and have no holes; replace them if they are damaged.
