• Do not over-tighten
• Do not use tools or filter wrenches to install filters – this may cause damage to the filter, resulting in poor filter performance or leaks
• Do not use grease to lubricate the gasket
• Check and inspect the condition and security of the threaded spigot
• Dispose of any used oil or fuel filters in a safe and proper manner in accordance with local, state, and federal regulations

• When changing any filter that has a gasket, use caution as old gaskets may stick!
• Remove used gaskets and clean the sealing area thoroughly
• Always install a new gasket when changing filter

• Always store filters in their original packaging and cartons in a cool, dry, contamination-free environment.
• Handle filters with care to prevent filter damage
• If a product box has layers of contaminant, be careful so that the contaminant does not get on the new filter as you remove it from the box
• Practice ‘first-in, first-out’ with your inventory. When possible, always use the oldest inventory first.
• Check the condition of the element prior to fitting. Check the exterior of filter for signs of damage and check the inside of the filter element for visible contamination.
