Guzzler 24 VDC pumps that shipped prior to 10/1/2016 were equipped with a permanent magnet motor, as well
as a motor linkage that featured a rod end bearing with a grease fitting that required periodic lubrication. Guz-
zler 24 VDC pumps that shipped subsequent to 10/1/2016 were equipped with a connecting rod that featured a
self-lubricating bearing and need no lubrication.
If your Guzzler has a grease fitting on its connecting rod, we recommend that the bearing be lubricated every 400
hours of operation or, more frequently, if operating conditions are such that the bearing begins to make a
squeaking noise. The fitting can be accessed by removing the screw that attaches the front of the pump guard to
the back of the guard plate.

The fitting can be lubricated with standard multi-purpose NLGI Grade 2 lithium grease.
