Good To Know
Q: What is the benefit of having an inner filter? A: The inner safety filter provides backup protection if the outer filter is damaged or improperly sealed. It also prevents debris from entering the engine during outer filter changes.
Q: How do I know when to change this filter set? A: Monitor the air restriction indicator on your machine; when it reaches its limit, replace the outer and inner filters together. For extremely dusty conditions, inspect the outer filter every 250 hours.
Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
