MAINTENANCE
WARNING:
When servicing, use only identical replacement parts. Use of any other parts may create a hazard or cause product damage.
WARNING:
Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust. If operation is dusty, also wear a dust mask.
WARNING:
Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to stop, and disconnect spark plug wire and move it away from spark plug. Failure to follow these instructions can result in serious personal injury or property damage.
GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use. Use clean cloths to remove dirt, dust, lubricant, grease, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum- based products, penetrating lubricants, etc., come in con- tact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury.
Only the parts shown on the parts list are intended to be repaired or replaced by the customer. All other parts should be replaced at an Authorized Service Center.

replacing the spark arrestor
The spark arrestor must be cleaned or replaced every 50 hours or yearly to ensure proper performance of your product. Spark arrestors may be in different locations depending on the model purchased. Please contact your nearest service dealer for the location of the spark arrestor for your model.
CLEANING THE EXHAUST PORT and muffler
Depending on the type of fuel used, the type and amount of lubricant used, and/or your operating conditions, the exhaust port and muffler may become blocked with carbon deposits. If you notice a power loss with your gas powered tool, you may need to remove these deposits to restore performance. We highly recommend that only qualified service technicians perform this service.
STORing the product
The following steps should be taken before storing the cultiva- tor for the season.
Fuel Tank:
nDrain the fuel tank completely into a container approved for gasoline. Even under ideal conditions, stored fuel containing ethanol or MTBE can start to go stale in 30 days. Stale fuel has a high gum content and can clog the carburetor and restrict fuel flow. The fuel tank should also be drained if the cultivator will not be used for more than two weeks.
nRestart the engine to make sure no fuel is left in the carbu- retor. Run the engine until it stops. This helps prevent gum deposits from forming inside the carburetor and possible engine damage.
Spark Plug:
nDisconnect spark plug wire and remove the spark plug. Pour a teaspoon of clean,
nLeaving the spark plug out, pull the starter cord two or three times to coat the inside of the cylinder wall.
nInspect spark plug and clean or replace, as necessary.
nReinstall the spark plug, but leave the spark plug wire dis- connected.
