STEP 1 REMOVE AND CLEAN Clean sealing area of filter and filter housing with a clean soft rag. Tap the filter on a hard surface to remove and loosen large paricles and debris. (A soft brush may be used to loosen large particles of debris or bugs.) Use S&B’s Filter Cleaner to clean the filter. Gently rinse out the cleaner using low pressure water. Let filter dry for at least 24 hours. Remove dirty replacement filter STEP 2 FILL AND APPLY Fill applicator with exact amount of oil required for your filter. Starting 1/2 way from base make 2-3 passes around the circumfrence of the filter in the same area. Repeat this process evenly spacing out the passes. STEP 3 INSPECT AND INSTALL Allow oil to bleed for 20-30 minutes. Inspect the filter for any white areas the oil did not cover. With the remaining oil in the applicator apply a small amount of oil to those white areas. DO NOT over oil your filter.
