SECTION 9: OFF-SEASON STORAGE
The following steps should be taken to prepare lawn
mower for storage.
• Clean and lubricate mower thoroughly as described
in the lubrication instructions.
• We do not recommend the use of pressure
washers or garden hose to clean your unit. They
may cause damage to electric components,
spindles, pulleys, bearings or the engine. The use
of water will result in shortened life and reduce
serviceability.
