10.3 During operation
The machine must always operate with the hood down and closed.
During operation, it is necessary to verify that the cooling air intake openings are free of foreign objects
such as pieces of paper, plastic, etc. as these materials can create obstructions to the ventilation system.
Figure 10.3-1 Exhaust pipe
WARNING: Areas near the exhaust pipes are very hot, and exhaust gases are harmful.
Avoid coming in close proximity of the exhaust system.
10.4 Stopping the engine
By turning the “ON/OFF” switch (Part 4 Figure 8.1-1) to the "OFF" position, the pressure in the tank lowers
to 3-3.5bar/43-51psi.
As soon as the pressure reaches 3-3.5bar/43-51psi, the engine automatically stops.
10.5 After stopping the machine
1) If the machine has operated in dusty environments, it will be necessary to replace the air filter and check
the status of the cooling radiator; if the fins are obstructed by debris, remove the debris as needed.
2) Check that during the working phase there is no leaking of fuel or lubricating oil inside the machine.
3) When possible, place the machine away from the elements.
