LUBRICATION
HAMMER MOUNTED 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. Make sure there is a full grease
cartridge (a54) installed in the Hammer
Mounted Auto Lube assembly. Ensure
that the flat seal (a65) in the lubrication
passage (176) is not damaged. 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) at the
hammer assembly (KK).
5. Attach a grease gun (t37) or power
greaser to the grease fitting (30) on the
front side of the Hammer Mounted Auto
Lube pump assembly (FZ).
