GENERAL DESCRIPTION 

This Rechargeable Grease Gun is a fully automated, battery powered grease gun developed  for manual 
lubrication of grease points. It  includes a pressure relief valve to expel excessive pressure (8000 psi) in the 
case of a blocked bearing, fitting, or lubrication line. This Rechargeable Grease Gun is driven by a small, 
low voltage electric motor connected to a three-stage planetary gear reducer. The rotary motion of the 
motor is converted into a reciprocating motion of the plunger through an eccentric and yoke mechanism. 
This Rechargeable Grease Gun is a positive displacement single acting pump.
