WARNING: When transporting the tiller, turn the fuel valve OFF and keep the tiller level to prevent fuel
spillage. Fuel vapours or spilled fuel may be ignited.
Before storing the unit for an extended period:
1. Be sure the storage area is free of excessive humidity and dust.
2. Drain the fuel.
WARNING: Gasoline is highly flammable and explosive under certain conditions. Do not smoke or
allow flames or sparks in the area.
- With the fuel valve turned OFF, remove and empty the fuel strainer cup.
- Turn the fuel valve ON and drain the gasoline in the fuel tank into a suitable container.
- Replace the fuel strainer cup and tighten securely.
- Drain the carburettor by loosening the drain knob. Drain the gasoline into a suitable container.
3. Pull the starter grip until resistance is felt. Continue pulling until the notch on the starter puller aligns
with the hole on the recoil starter.
At this point, the intake and exhaust valves are closed and this will help to protect the engine from
internal corrosion.
4. Change engine oil.
5. Cover tiller with plastic sheet.
Do not place the tiller with the handlebars on the ground. It will cause the oil entering the cylinder or
the fuel spillage.

Troubleshooting

When the engine will not start:
·Is there enough fuel?
·Is the fuel valve on?
·Is the engine switch ON?
·Is gasoline reaching the carburettor?
- To check, loosen the drain knob with the fuel valve ON. Fuel should flow out freely.
- Retighten drain knob.
WARNING: If any fuel is spilled, make sure the area is dry before testing the spark plug or starting the
engine. Fuel vapour or spilled fuel may ignite.

- Is there a spark at the spark plug?
Remove the spark plug cap. Clean any dirt from around the spark plug base, then remove the spark plug.
Install the spark plug in the plug cap.
Turn the engine switch on.
Grounding the side electrode to any engine ground, pull the recoil starter to see if sparks jump across the gap.
If there is not spark ,replace the plug.
If OK, try to start the engine according to the instructions.
