LUBRICATION
Use a high quality Rock Drill Oil with a flash point between 370
and 450 degrees Fahrenheit (188 and 232 degrees Celsius).
Proper lubrication is the most important single factor
responsible for the service life of the Hammer Drill. A Hammer
Drill can be severely damaged during the first few minutes of
operation if not properly lubricated, it is therefore
recommended to put 2 to 3cm³ of oil into the drill's hose.
Periodically connection before startup.the entire tool should be
disassembled, the parts should be washed in a clean,
nontoxic, nonflammable, commercial solvent, dried completely
and well oiled before reassembly.
Always use an air line lubricator with this Hammer Drill. A
Doosan Air Line Lubricator (CPN 35371111) is recommended
for proper lubrication. Install it in the main air supply line within
1.5 meters (5 ft.) of the Hammer Drill.
The oil level in the air line lubricator should be checked at the
beginning of each eight hour shift and once during the shift.
Every effort must be made to avoid oil contamination from dirt
or other impurities. Oil should be kept in covered containers
and stored. if possible, in an area that is relatively dust free.
Before filling the air line lubricator, the area around the filler
plug should be wiped clean.
The oil used in the lubricator must be a well refined petroleum
lubricating oil. It must be suitably compounded to provide the
specified consistency and film strength, and be further
compounded to provide the specified steam emulsion number.
The latter is required to provide a satisfactory lubricant for
such Hammer Drills where water or wet air is encountered.
The oil must also be substantially non-corrosive to steel and
bronze, and contain little or no sulphur.
The composition of the “film strength” additive is not specified.
The additive must be suitable for use with both steel and
bronze, and be substantially non-corrosive to both metals.
Except for consistency, all tests must be conducted in
accordance with the standard method (latest edition) of the
American Society for Testing Metals.
