Operation
Using the rock drill for the first time
When the rock drill arrives from the factory, the inside of the machine is coated with
heavy oil to prevent corrosion.
After unpacking and installing the machine, pour a small amount of lubrication
oil into the air connection and operate the machine 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 FY200A lubricator connected to the air line.
