Lubrication Intervals
IMPORTANT: The recommended service intervals are based on normal conditions;
severe or unusual conditions may require more frequent lubrication.
Perform each lubrication and service procedure at the beginning and end of each season.
Clean grease fittings before using grease gun, to avoid injecting dirt and grit into the
bearing. Replace any lost or broken fittings immediately. If a fitting fails to take grease,
remove and clean thoroughly, replace fitting if necessary. Also check for failure of
adjoining parts.
