STRAINERS
Strainers must be cleaned regularly to avoid pump starvation.
Schedule will depend upon the application and conditions.

running.
Sleeve bearings (bushings) are lubricated by the liquid being
pumped. Additional lubrication is not required.
IF EQUIPPED: Blackmer gear reducers are shipped from the
factory without oil in the gearcase. Fill with the grade of oil
indicated on the reducer tag. Change the oil after the first 48
hours of use and approximately every 500 hours of use
thereafter.
