The cooling system consists of:
1Air intake on the starter.
2Fins on the flywheel.
3Cooling fins on the cylinder.
4Cylinder cover (directs cold air over the cylinder).
Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.
Bevel gear
The bevel gear is filled with the right quantity of grease at the factory. However, before using the machine you should check that the bevel gear is filled
The grease in the bevel gear does not normally need to be changed except if repairs are carried out.
Air filter
The air filter must be regularly cleaned to remove dust and dirt in order to avoid:
•Carburettor malfunctions
•Starting problems
•Loss of engine power
•Unnecessary wear to engine parts.
•Excessive fuel consumption.
Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.
Cleaning the air filter
Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Ensure that the filter is dry before refitting it.
An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter
must always be replaced.
If the machine is used in dusty conditions the air filter should be soaked in oil. See instructions under the heading Oiling the air filter.
