Nut and bolt check
Check that the main fixing nuts and bolts are tight.
If the bolts are loose tighten them to the prescribed torque (see the “Nuts and bolts tighten-
ing torques chart”).
Checking and cleaning the supplementary air filter
Caution - Care
Never carry out maintenance operations on the air filter with the engine on to pre-
vent dirt and debris suspended in the air from seriously damaging the engine.
In certain operating conditions (dust, dirt and debris), the air filter may need to be
checked and cleaned more frequently.
Use the valve (A) to release the dust contained in the fil-
ter.
Check the clog signal (B) every day.
When the signal is in the red area, it means the filter is
clogged and must be cleaned or replaced (see “Replac-
ing supplementary air filter cartridges”).
For checking and cleaning operations proceed as out-
lined below.
