Damage Caused by Lack of Lubrication

Question Page 5048912 Football Style Lubricator Features Drill Doctor

It is a fact that lack of lubrication is the leading cause of failure of most equipment.

Rock drills need better lubrication than a gasoline engine!
There is much more shock loading on rock drill parts than engine parts.
The piston in a rock drill is striking the drill steel as well as reciprocating in the cylinder.

Lack of lubrication can be prevented by :

Installing a Joy 5048912 lubricator in the air line within 12 feet of the drill (or other equipment).
Select a qood quality rock drill oil or rock drill grease from a recognized brand supplier.
Check the drill to be sure the line oiler is delivering proper lubrication.
Fill the line oiler at start of a shift, check 1/2 way through to be sure the reservoir is full.
