SERVICING YOUR HONDA TRIMMER

Fuel Filter and Fuel Tank Cleaning

1. Remove the fuel tank cap, and empty the fuel tank into

an approved gasoline container. Use a funnel to avoid

spilling gasoline.

2. Pull the fuel filter out through the fuel filler neck by

hooking the black fuel supply tube with a piece of wire,

such as a partly straightened paper clip.

3. Inspect the fuel filter. If the fuel filter is dirty, remove it

and wash it with nonflammable solvent. Be careful to

avoid damaging the filter.

Replace the filter if it is damaged or excessively dirty.

4. Rinse sediment from the fuel tank with nonflammable

solvent.

5. Insert the fuel filter in the fuel tank, and install the fuel

tank cap.
