Important Notes

• Verify Kohler part number 25 083 02-S before ordering

• This listing is for a replacement HDAC primary air filter element, not a complete air cleaner assembly or engine maintenance kit

• Kohler identifies this component as the primary air filter for designated Command PRO and Triad OHC engine applications

• Confirm compatibility with your specific Kohler engine model and specification number

• Verify the engine identification information before purchasing

• Manufacturer documentation identifies applications within the Command PRO CV460–CV493 and Triad OHC TH16, TH18, TH520, and TH575 engine families

• Not every engine configuration within these families necessarily uses the same air cleaner assembly

• Confirm that your engine is equipped with the appropriate heavy-duty air cleaner configuration

• Do not assume compatibility with every Kohler Command PRO or Triad engine

• Different Kohler engine configurations may require different air filters, filter dimensions, or mounting arrangements

• The equipment model or engine horsepower rating alone may not identify the correct replacement air filter

• Check the engine manufacturer's illustrated parts diagram for the correct filtration component

• Verify that your engine specifies Kohler 25 083 02-S

• Kohler's genuine parts reference guide lists an outside diameter of 3.5 inches and height of 7.3 inches

• Verify the original filter's inside diameter, sealing surfaces, and mounting configuration before installation

• Similar-looking cylindrical air filters may differ in height, diameter, sealing design, or filtration requirements

• Do not substitute an incorrectly sized air filter that may prevent proper sealing

• Confirm that the replacement filter matches the designated heavy-duty air cleaner housing

• This component serves as the primary filtration element in compatible air cleaner assemblies

• The corresponding Kohler safety air filter is 25 083 03-S

• The primary filter and safety filter perform different filtration functions

• Do not confuse Kohler 25 083 02-S with Kohler 25 083 03-S

• Kohler 25 083 01-S is a different primary air filter with a larger manufacturer-specified configuration

• Do not assume these different Kohler air filter part numbers are interchangeable

• The Oregon 30-708 is an aftermarket replacement reference for Kohler 25 083 02-S

• Additional aftermarket references include Rotary 11842 and Stens 100-533

• Aftermarket cross-reference numbers are provided for identification and are not additional parts included with this listing

• Confirm equipment-specific compatibility before substituting aftermarket filtration components

• This listing is for one primary air filter element

• Do not assume the secondary safety filter, air cleaner housing, mounting hardware, or additional service components are included

• Verify whether the existing safety filter requires separate inspection or replacement

• Follow the engine manufacturer's recommended air filter inspection and replacement intervals

• Maintenance intervals may vary depending on engine operating hours, equipment configuration, and environmental conditions

• More frequent inspection and replacement may be required in dusty, dry, or debris-heavy mowing environments

• Replace primary air filters that are excessively dirty, clogged, damaged, wet, contaminated, or otherwise unsuitable for continued use

• Do not continue operating the engine with a damaged filter element

• Shut off the engine and allow it to cool sufficiently before performing air cleaner maintenance

• Remove the ignition key and secure the equipment against unintended starting

• Disconnect the spark plug wires or applicable ignition connections when instructed by the manufacturer

• Wear appropriate protective gloves and eye protection during engine servicing

• Clean accumulated dust, grass clippings, and debris from the outside of the air cleaner housing before opening it

• Prevent dirt and foreign materials from entering the engine intake during maintenance

• Carefully remove the existing primary filter without dislodging contaminants into the intake passage

• Inspect the air cleaner housing for cracks, loose fasteners, damaged seals, or excessive contamination

• Check the existing safety filter for contamination or damage according to manufacturer instructions

• Do not remove or disturb the safety filter unnecessarily during routine primary filter servicing

• Verify that the replacement primary filter is properly positioned within the designated air cleaner housing

• Ensure the filter sealing surfaces are clean and free from damage

• Do not force installation if the replacement filter does not match the original mounting configuration

• Confirm that the primary air filter fits securely around the designated mounting and sealing surfaces

• Do not operate the engine with an improperly seated primary air filter

• Do not wash or oil the filter media unless expressly permitted by the engine manufacturer

• Do not use compressed air to clean the primary filter unless specifically authorized by Kohler

• Improper cleaning procedures may damage filtration media or reduce filtering effectiveness

• Replace damaged or excessively contaminated filter elements rather than attempting unauthorized cleaning methods

• Ensure all air cleaner covers, retaining clamps, and mounting components are securely installed before operation

• Confirm that the air cleaner housing is properly sealed to prevent unfiltered air from entering the engine

• Do not operate the engine without the required filtration components

• Operating without proper filtration may allow abrasive contaminants to enter the engine and accelerate internal wear

• Inspect the surrounding intake ducts and connections for loose fittings, cracks, or damaged sealing surfaces

• Verify proper engine starting and operation after completing air filter replacement

• A replacement primary air filter may not resolve engine performance problems caused by fuel system restrictions, ignition failures, carburetor faults, or unrelated mechanical issues

• Follow the engine manufacturer's recommended maintenance procedures and safety instructions

• Confirm current manufacturer spe
