Maintenance
Long Term
If storing the machine for a period of 30 days or more, you must follow proper storage and
winterisation guidelines to avoid any possible issues with the machine. Incorrect storage can lead
to possible fueling or engine issues that will not be covered by the warranty.
1 Allow the engine to fully cool down.
2
Drain all the fuel from the fuel tank and then run the machine until it has completely run out of
fuel to clear the remaining fuel from the fuel lines and carburettor.
3
Drain the oil from the engine.
4
With the machine drained from all fluids, follow the cleaning instructions in the 'Cleaning'
section.
5
Follow the maintenance section and check, service or replace serviceable items if required.
Visually inspect the machine and replace or repair any worn parts.
6
Lightly grease all moving parts on the machine.
7
Refill engine oil with new SAE 30 or 15w40 engine oil, fill to the upper mark on the dipstick.
8
Remove the spark plug and pour 1 teaspoon of fresh engine oil down the cylinder bore. Cover
the spark plug hole with a lint free clean cloth, ensuring no dirt or debris falls into the cylinder
chamber and gently pull the recoil starter handle to coat the cylinder bore with the fresh oil.
Refit the spark plug.
