Storage

Storage Safety

Shut off the machine and wait for all moving parts to stop before you leave the operator’s position. Disconnect the spark-plug wire, keep it away from the plug to prevent accidental starting, and allow the machine to cool before adjusting, fueling, unclogging, servicing, cleaning, or storing the machine.
Run the engine dry or remove the fuel with a hand pump; never siphon the fuel. If you must drain the fuel tank, do it outdoors.
Follow the instructions in this Operator’s Manual to safely unload, transport, and store the machine.
Do not store the machine with fuel in the fuel tank inside a building where ignition sources are present, such as hot water and space heaters and clothes dryers. Allow the engine to cool before storing the machine in an enclosure.
Always refer to the Operator’s Manual for important details if the machine is to be stored for an extended period.

Storing the Machine

Park the machine on a level surface, shut off the engine, and wait for all moving parts to stop before leaving the operating position.
Remove debris from the tines, axle, transmission housing, and engine.

Important: You can wash the machine with mild detergent and water. Do not pressure-wash the machine. Avoid excessive use of water, especially near the engine and transmission.
Coat the axles lightly with axle grease.
Service the air cleaner; refer to Servicing the Air Cleaner.
Change the engine oil; refer to Changing the Engine Oil.
Prepare the machine for storage for over 30 days as follows:
1. Add fuel stabilizer/conditioner to fresh fuel in the tank. Follow mixing instructions from the fuel stabilizer manufacturer. Do not use an alcohol-based stabilizer (ethanol or methanol).
2. Run the engine to distribute conditioned fuel through the fuel system for 5 minutes.
3. Shut off the engine, allow it to cool, and drain the fuel tank.
4. Start the engine and run it until it shuts off.
5. Dispose of fuel properly. Recycle the fuel according to local codes.
  
  Important: Do not store fuel containing stabilizer/conditioner longer than the duration recommended by the fuel-stabilizer manufacturer.
Remove and check the condition of the spark plug; refer to Servicing the Spark Plug. With the spark plug removed from the engine, pour 15 ml (1 tablespoon) of engine oil into the spark plug hole. Install the spark plug and pull the recoil rope 3 times to coat the cylinder with oil. Do not install the wire on the spark plug.
Check and tighten all fasteners. Repair or replace any part that is damaged.
Paint all scratched or bare metal surfaces. Paint is available from your Authorized Service Dealer.
Store the machine in an upright position in a clean, dry garage or storage area. Keep it out of reach of children or other unauthorized users. Cover the machine to protect it and keep it clean.

Troubleshooting

Problem	Possible Cause	Corrective Action
The engine does not start.	The fuel tank is empty. The spark-plug wire is loose or disconnected. The engine switch is in the Off position. The choke lever is not in the Choke position during cold start.	Add fuel. Install the wire on the spark plug. Move the switch to the On position. Move the choke lever to the Choke position.
The engine runs rough or floods during operation.	The air filter is dirty.	Clean or replace the air filter.
The engine is difficult to start.	Stale fuel is in the fuel system. The spark-plug wire is loose or disconnected. The drive-control lever is engaged.	Drain the fuel tank and add fresh fuel. Install the wire on the spark plug. Release the drive-control lever.
The engine misses or lacks power.	The tilling depth is too deep. The air cleaner is dirty or damaged. The carburetor is out of adjustment. The spark plug is wet, pitted, fouled, or the gap is incorrect. Stale fuel is in the fuel system.	Raise the tines by raising the drag stake. Clean or replace the air-cleaner element. Contact an Authorized Service Dealer Install a new, correctly gapped spark plug. Drain the fuel tank and add fresh fuel.
The tiller moves forward during starting.	The drive-control lever is compressed. The belt tension is incorrect.	Release the drive-control lever. Check the belt tension and adjust it as necessary.
The tiller is difficult to control when tilling; the machine jumps or lurches forward.	The dirt is too compact. The drag stake is set too high. The tines are installed incorrectly.	Lower the engine speed. Lower the drag stake for greater resistance and control of the machine. Install the tines are installed with the edges forward.
Belts squeal during forward operation.	The belt tension is incorrect	Check the belt tension and adjust it as necessary.
There is a constant buzzing sound while the drive-control lever is compressed.	The drive-control lever is not fully compressed. The wire belt guide is too close to the idler pulley. The belt tension is incorrect The belt is stretched.	Fully compress the drive-control lever. Properly space the wire belt guide from the idler pulley to clear the belt. Check the belt tension and adjust it as necessary. Replace the belt.
