Off-Season Storage

If the tiller will not be used for a period longer than 30 days, the following steps should be taken to prepare the tiller for storage.

1.Clean the exterior of engine and the entire tiller thoroughly. Lubricate the tiller as described in the lubrication instructions.

2.We do not recommend the use of pressure washers to clean your unit. They may cause damage to electric components, spindles, pulleys, bearings or the engine. The use of pressure washers will result in shortened life and reduce serviceability.

3.Refer to the engine manual for correct engine storage instructions.

4.Wipe tines with oiled rag to prevent rust.

5.Store tiller in a clean, dry area. Do not store next to corrosive materials, such as fertilizer.

NOTE: When storing any type of power equipment in an unventilated or metal storage shed, care should be taken to rustproof the equipment. Using a light oil or silicone, coat the equipment and especially any springs, bearings, and cables.
