Supply of grease to gear case

Supply grease (Shell Albania 3 or equivalent ) to the gear case through the grease hole every 30 hours.

Suction head in the fuel tank

The fuel filter (A) of the suction head is for filtering the fuel to the carburetor. A periodical visual inspection of this fuel filter is highly recommended.

To inspect the fuel filter, open the tank cap and pull out the suction head through the opening of the tank using a wire hook.

If the filter is found to have hardened, polluted or clogged up, it should be replaced.

Insufficient fuel supply caused by the deteriorated filter will result in the poor performance of the engine. It is therefore important to replace the fuel filter at least quarterly to ensure fuel-supply to the carburetor.

Cleaning of muffler exhaust port

Check the muffler exhaust port (B) regularly. If it is clogged by carbon deposits, scratch out the deposits carefully with a suitable tool.

STORAGE

When the Brush Cutter/String Trimmer is in storage for a long time,

1Drain all fuel from the fuel tank into a container approved for gasoline. Run the engine until it stops.

2Clean all foreign material from the machine and store it in a well-venti- lated place that is not accessible to children.
