Garden tillers relieve you from manually planting, breaking new ground or introducing new materials to your soil. But the machine is vulnerable to the dirty conditions where it's operated. Consult your owner's manual for specific directions for proper care. Always wipe down the machine after each use. Clean the fuel tank and air filter regularly so your tiller doesn't stall or run erratically. Tap paper filters against a hard surface to dislodge dirt. Other filter styles can be washed with mild household detergent and water. Let it dry before reinstalling. Also, clear any blocked areas on the fuel tank cap vents, otherwise, the garden tiller could run infrequently. As with other power tools we discussed, adjust the carburetor to ideal conditions based on your manual's directions.
