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 Pickhammer. A
Pickhammer can be severely damaged during the first few
minutes of operation if not properly lubricated. Periodically,
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.
The method used to provide adequate lubrication is dependent
upon actual operating conditions and customer preference.
a.
If operation is intermittent, and the air supply hose does
not exceed 6 meters (20 ft.) in length, a
compressor–mounted lubricator can be used.
b.
If operation is continuous, that is 8 hours a day, an
Ingersoll–Rand No. 8LUB16C Air Line Lubricator is
recommended for proper lubrication. Install it in the main
air line within 3.5 meters (11.5 ft.) of the Pickhammer.

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.

Regardless of the method of lubrication, the lubricating oil
reservoir must be serviced with recommended oil as
frequently as necessary to prevent any possibility of the
Pickhammer running dry.
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 Pickhammers 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.
