Information:
You must read and understand the warnings and instructions contained in the Safety section of this manual before performing any operation or maintenance procedures.Before proceeding with Every 50 Hour maintenance, perform all Daily maintenance requirements.Dust Collector
Never run the engine without an air cleaner installed. Never run the engine with a damaged air cleaner. Do not use filter elements with damaged pleats, gaskets or seals. Dirt entering the engine causes premature wear and damage to engine components. Air cleaners prevent airborne debris from entering the engine through the air inlet.
Clean
Typical two stage air cleaner. Individual applications may be different.1. Remove the air cleaner cap (1). Remove the dust collector cup (2).2. Wipe dust collector cup with a clean, dry cloth.3. Install the cup. Install and secure the cap. If equipped with a heavy duty air cleaner: refer to the Heavy Duty Air Cleaner topic in the Daily section of this manual for information about cleaning the dust collector cup.Light Duty Air Cleaner (If Equipped)
Light duty air cleaners are not serviceable (washable). Light duty air cleaners are intended for a 50 service hours of maximum use, or one year, whichever occurs first. However, engines operating in a severe environment may require more frequent air cleaner replacement.Dust conditions vary for different operating environments. Service the air cleaner at regular intervals as determined by the operating environment. Check the air cleaner service indicator (if equipped) daily.Check the air cleaner for cleanliness and damage such as rips and tears. Replace the air cleaner element at the required service interval, or more often as determined by the operating environmental dust conditions. To Replace the Light Duty Air Cleaner Element: 1. Loosen the clamp (2) fastening the air cleaner element (1) to the air inlet, and remove the dirty element and clamp.2. Install the clamp on a new element.3. Install the new element to the air inlet and tighten the clamp.
