6.4 Cleaning and replacing the air filter

important to clean and periodically replace the air filter
cartridge. An inefficient filter can cause loss of engine

securing jerky levers.(fig.4 rif.4).
- Remove the filter cartridge and insert a new on
positioning it carefully;
- Replace the lid and rehook it with the securing jerky
levers. (fig.4 rif.4).
- Rehook the hood with the securing jerky levers.
(fig.5 rif.1)
ATTENTION
Clean the air filter cartridge every 100 hours of opera-
tion.
Shorten this interval if the generator is operated in a
particularly dusty environment.
Replace the cartridge when it is excessively fouled or
damaged.

6.5 Cleaning the air intake grids

Periodically check the cooling air intake and discharge
grids (fig. 2 ref. 4-5) and the cylinder cooling fins for fouling.
These must be free of any foreign bodies which could
obstruct the flow of cooling air (i.e. leaves, paper, rags,
etc.).
