Transporting; Taking Care Of Unexpected Problems - Honda GX25 Mode D'emploi

Draining the Fuel Tank and Carburetor
Gasoline is highly flammable and explosive, and you
can be burned or seriously injured when handling fuel.
• Stop the engine and keep heat, sparks, and flame
away.
• Handle fuel only outdoors.
• Wipe up spills immediately.
1. Make sure the engine oil filler cap is tightened securely.
2. Remove the fuel filler cap and drain the fuel into an approved
gasoline container by tipping the engine toward the fuel filler
neck.
3. Press the priming bulb several times until there is no more fuel
in the fuel return tube.
4. Tip the engine toward the fuel filler neck again to drain the fuel.
FUEL RETURN TUBE
5. After all fuel has drained, reinstall the fuel filler cap securely.
Engine Oil
1. Change the engine oil (see page 9).
2. Loosen the 5 mm hex bolt, then remove the top cover (see
page 11).
3. Remove the spark plug (see page 11).
4. Apply a couple of drops of clean engine oil into the cylinder.
5. Install the top cover temporarily.
6. Pull the starter grip several times to distribute the oil in the
cylinder.
7. Remove the top cover, then reinstall the spark plug.
8. Install the top cover, and tighten the 5 mm hex bolt securely
(see page 11).
9. Pull the starter grip slowly until resistance is felt.

Storage Precautions
If your engine will be stored with gasoline in the fuel tank and
carburetor, it is important to reduce the hazard of gasoline vapor
ignition. Select a well ventilated storage area away from any
appliance that operates with a flame, such as a furnace, water
heater, or clothes dryer. Also avoid any area with a
spark-producing electric motor, or where power tools are operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
Keep the engine level in storage. Tilting can cause fuel or oil
leakage.
With the engine and exhaust system cool, cover the engine to keep
out dust. A hot engine and exhaust system can ignite or melt some
materials. Do not use sheet plastic as a dust cover.
A nonporous cover will trap moisture around the engine, promoting
rust and corrosion.
Removal from Storage
Check your engine as described in the BEFORE OPERATION
CHECKS section of this manual (see page 4).
If the fuel was drained during storage preparation, fill the tank with
fresh gasoline. If you keep a container of gasoline for refueling, be
sure it contains only fresh gasoline. Gasoline oxidizes and
deteriorates over time, causing hard starting.
ENGINE OIL FILLER CAP If the cylinder was coated with oil during storage preparation, the
engine will smoke briefly at startup. This is normal.

TRANSPORTING

If the engine has been running, allow it to cool for at least 15
PRIMING BULB
minutes before loading the engine-powered equipment on the
transport vehicle. A hot engine and exhaust system can burn you
and can ignite some materials.
