• Oil bath air filter

Unhook lock "A", figure 4, take out the bottom air filter bowl, wash all parts with care
using diesel oil (figure 13) and dry them using compressed air. Before assembly fill the
float chamber with engine oil up to the level mark (figure 4-5).
Do not exceed the level shown in the filter when adding oil. The extra oil might
be sucked by the engine thus causing a sudden increase in the rotation speed.
Always use protective goggles when compressed air is used.
Never use solvents with a low flash point to clean the filter element. Such
action could cause an explosion.
Make sure that the filter is mounted in the correct way otherwise dust and other
impurities could ilfiltrate into the intake ducts.
Clean the air filter frequently, as dust particles can wear the internal parts of the engine
(cylinder, piston, crankshaft, pivots, etc.) very quickly (in just a few operation hours). If
the working area is very dusty, change the oil in the filter every 4-5 working hours.
Choose filters which are adequate for the specific operating conditions.

• Fuel filter

Drain the fuel tank completely, remove the cartridge (figure 14 or figure 15) by rotating
it anticlockwise.
Fill the new cartridge with diesel oil and screw it on tightening it manually.
Original Ruggerini cartridges are recommended.
If the fuel supply circuit is empty, it is not necessary to purge the air as the engine is
supplied with an automatic air relief valve.
The engine might not start immediately as the circuit must fill up first: before starting,
use the manual pump lever found on the fuel supply pump (figure 7) to fill up the
circuit. Do not attempt to start the engine repeatedly using the starter. Follow
recommendations regarding electric start on pages 27-28.
The breather pipe and the thread of the fuel tank cap should be checked regularly to
verify that they are free of impurities ("B", figure 6), particularly if the machine is
operated in a dusty environment.
Do not throw away spent cartridges, but hand them to specialised waste
disposal centres.
