acidity and type of grass. Ask advice from a supplier of fertilising products.
• Aeration: The soil under the lawn has often been compressed from walking or driving on it. The
grass does not get enough air as a result. This also prevents easy drainage of rain water and
fertilisers. These are some of the causes of slow growth of the grass and increased growth of
surface parasites, such as moss. Opening up the soil requires aeration at a deeper level.
• Sanding: Sanding the lawn can help provide air to the top layer. Sanding can best be done after
dethatching or aeration. Sharp sand is the best choice.
• Irrigation: To protect itself from drought, grass will slow down its own growth during continu-
ous sunny weather and high temperatures. Regular watering is recommended if a period of
drought starts after dethatching. A humid soil below the grass is crucial for the absorption of
fertilisers, continued growth and recovery of the lawn.
9.10. Fault diagnosis
9.10.1. The engine fails to start after idle periods.
If the machine fails to start up after periods of inactivity, then this could be the result of any of
the following causes:
a. Lack of petrol
b. Petrol is stale
c. Bad spark plug
d. Lack of oil
Caution: Before examining possible reasons for the fault, make sure the ON/OFF
switch for the engine is turned to the OFF position.
a. Lack of petrol
First check that the fuel tap (if any) is open.
Then § 12 ‘Storing the machine’ it is advisable to remove any residual petrol before long term
storage of the machine. It may be the case that you forgot to refuel the machine. Check that the
tank is adequately filled and refuel if necessary A few attempts to start will be necessary to pump
the petrol into the carburettor. Close the choke - the petrol will now be sucked into the line. The
engine will start running as soon as the carburettor has filled.
b. Petrol is stale
Petrol has a limited shelf life. Petrol that has been sitting in petrol tank for more than a few
months can cause starter problems. It also smells totally different than fresh petrol.
Pump out the contents of the fuel tank and refuel with fresh petrol.
