SECTION 7: OFF-SEASON STORAGE

If the tiller is to be inoperative for a period longer than 30 days, the following precautions are recommended.

Working outdoors, drain all fuel from the fuel tank. Run the engine until it stops from lack of fuel.

WARNING: Do not drain fuel while smoking, or if near an open fire.

Drain all the oil from the crankcase (this should be done after the engine has been operated and is still warm) and refill the crankcase with fresh oil.

Protect the inside of the engine for storage as instructed in the separate engine manual packed with your tiller.

Clean the engine and the entire tiller thoroughly.

Wipe tines with oiled rag to prevent rust.

We do not recommend the use of pressure washers to clean your unit. It 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.

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, especially any springs, bearings and cables.

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