What maintenance tasks should I perform regularly on my GL350?

Periodically clean the ventilation slots with a soft brush or dry cloth, clean the motor housing with a damp cloth (avoid abrasive or solvent-based cleaners), clean the cutting line and spool with a soft brush or dry cloth, and use a dull scraper to remove accumulated grass and dirt from under the guard. Do not allow liquid to penetrate the tool or submerge any parts in liquid. (Page 10-11)
