Replace the oil every 25 hours if the engine is working at full load or at high temperatures.

Clean the air lter more often if the machine is working in dusty areas.
For the operations that are not difcult for the nal
user the assistance centre must maintain the mo-
tor in perfect efciency, in accordance with two
intervention lines:
- Tuning the engine whenever possible.
- Recommending the client a routine maintenan-
ce program at set intervals (e.g. at the end of
the season or before a long period of inactivity).
4.2. Engine tuning program
As part of general engine tuning or any intervention
on the machine, it is recommended that the Service
Centre performs a series of operations aimed at
maintaining the engine’s efciency.
Tuning should involve:
- external blowing and cleaning the cylinder
head, cylinder and mufer by removing any
remains of grass and mud;
- checking the oil level, topping up or replacing
parts if necessary;
- cleaning the air lter [
5.1];
- adjusting minimum and maximum speeds [
7.3 and 8.4];
- inspecting the condition of the spark plug; che-
cking the distance between the electrodes [
9.1];
- tightening the screws [
11.2];
- functional test [ 4.3].
Should the checks and adjustments fail to achieve
a satisfactory result, refer to chapter [ 14] for
troubleshooting.
