LUBRICATION
AUTO LUBE GREASE LINE PRE-FILLING
It is mandatory that the supply line from the Auto Lube main pump to the connection on
the hammer is primed with grease before it is used. Failure to do this will result in no
grease being administered to the hammer tool for two to three hours. This can and will
result in severe galling of the tool and tool bushing.
PRIMING THE GREASE LINE
1. Place the hammer in a vertical position,
applying enough down force to push the
tool up into the hammer.
2. Turn the excavator/backhoe off.
3. Fill the NPK Auto Lube pump reservoir
with a power greaser through the fill
fitting (30) on the side of the pump or
from the top by removing the fill cover
(a1). Use a premium quality grade
EP#2, high temperature grease with
wear inhibiting additive. (See
“CORRECT GREASE FOR
HYDRAULIC HAMMERS”.)
4. Disconnect the grease line (29) from the
Auto Lube main pump cartridge (a4).
