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.

Cooling Fin Inspection 
Inspect the engine cooling fins, and clean out any dirt and debris.

On both the HHT25S and HHT31S, it is necessary to remove the top cover. Removal procedures are 
located on page 37 for HHT25S and page 38 for the HHT31S.
