INTRODUCTION
The NPK AUTO LUBE System is designed to automatically provide a supply of grease
to the hammer tool bushing - increasing tool bushing life by reducing tool bushing wear.
Due to its compact design, it can be mounted directly to the hammer.
The AUTO LUBE system utilizes a hydraulic motor-driven high pressure pump capable
of pushing low viscosity EP2 grease in cold weather. The pump is activated via by-pass
hose lines from the hammers pressure and return lines, to run whenever the hammer is
operated.
The NPK AUTO LUBE system is comprised of the grease pump assembly, adapter
fittings and hoses at the pump, hammer and hammer top bracket. The grease line
length varies according to the NPK hammer size. Use 1/4” maximum I.D. line, 5000 psi
minimum working pressure with 6 JIC hose ends for the grease line from the pump to
the hammer.
For help with any installation problem, or for additional information, call the NPK Service
Department at 1-800-225-4379.
