Operation
Using the rock drill for the first time
When the rock drill arrives from the factory, the inside of the tool is coated with
heavy oil to prevent corrosion.
After unpacking and installing the tool, pour a small amount of lubrication oil into
the air connection and operate the tool on partial throttle to clean the interior.
Follow this immediately with a liberal amount of air tool oil.
The rock drill and pusher leg are lubricated with oil mixed with compressed air,
which is taken to the parts that need continuous lubrication. Oil is metered into the
compressed air using the FY250 lubricator connected to the air line.
