Low or inadequate air pressure at the Rock Drill is costly and wasteful, and an insufficient volume
if air will not allow it to operate efficiently.
Choice of Lubricant
Using the proper lubricant ensures the machine operates normally, reduces part wear and
increases working life. Select the lubricant in accordance with the tool's operating environment
temperature.
Proper lubrication is the most important single factor responsible for the service life of a
Rock Drill. A Rock Drill can be seriously damaged during the first few minutes of operation
if it is not properly lubricated.
Improper lubrication will prevent proper indexing of the rotation and ultimately reduce
the rotation speed. Prolonged usage of the Rock Drill without proper lubrication will cause
damage to the unit. Always use an air line lubricator with these tools.
Install the Lubricator approximately 11.5 ft. (3.5 m) from the tool.
At the beginning of each eight hour shift and once during the shift, fill the air line lubricator
with the recommended oil.
Before filling any reservoir, clean the area around the fill plug.
Adjust the air line lubricator to provide a light film of oil at the drill steel shank. Excessive
lubrication is indicated by blue smoke at the exhaust or oil running down the drill steel. Start
the adjustment by turning the lubricator needle valve clockwise until it is closed. Turn the valve
counterclockwise 3/4 of a turn for an initial starting point. Rotate the valve one way or the other
until the desired amount of lubrication is obtained. Always place the tool against the work
when checking lubrication.
When using a compressor mounted lubricator, hose length must not exceed 50 ft. (15 m).
When exhaust freezing occurs, add anti-freeze lubricant directly through the air inlet. Use
"KILFROST" lubricant or equivalent.
Store all oil in covered containers in an area that is relatively dust free to prevent contamination.
