Troubleshooting

PROBLEM

The petrol-driven lawnmower 

doesn’t work

Mowing is difficult

The cut grass is not collected 

in the grass-catcher.

The lawnmower vibrates 

abnormally

SOLUTION

Remove the spark plug cap and check oil and petrol levels 

Check that petrol is fresh and clean. Petrol that has been stored in 

the machine for over 28 days will need to be drained as this will have 

gone stale.
Clean the spark plug and filter which may be dirty or replace them.

Remove the spark plug cap and check the blade’s condition. 

If worn or damaged, replace it with a new blade. 
Remove the spark plug cap and check the blade’s tightening torque. 

Remove the spark plug cap and make sure the chassis interior is not 

obstructed. If it is, clean it.
Remove the spark plug cap and make sure the blade has not 

received a blow. If it has, replace it.  
Increase the cutting height if the grass is too high. 

Remove the spark plug cap and make sure the blade is not severely 

damaged. Contact your dealer.

Troubleshooting

Blades must always be marked  . Given product evolution, the above mentioned blades may 

be replaced in time by others, with similar interchangeable and operating safety features. 

Reassemble the blade (2) with the code and markings facing the ground, following the steps 

indicated in the illustration. Tighten the central screw (1) using a torque wrench set to 

35-40 Nm.

[2]  Drive adjustment

     On power-driven models, the proper belt tension is obtained by adjusting the nut (1) to get 

the indicated measurement (6 mm).
