Before connecting the air hose to the air connection, pour 2 to 3 oz. (.06 to .09 L) of Rock Drill Oil
into the inlet. The tool is shipped from the factory with a standard 3/4" NPT male inlet thread.
Make sure all hoses and fittings are the correct size and are tightly secured. See diagram
Dwg. 16572133 on page 2 for a typical piping arrangement.
Air Requirements
An air compressor of sufficient capacity is needed to provide the necessary volume of air at the
most efficient operating pressure to ensure effective and economical operation of the jackhamer.
The air requirements represent air pressure at the jackhamer inlet and not at the compressor.
There is always a certain amount of pressure drop between the compressor and the jackhamer;
only the pressure and volume at the tool is effective in doing work. If a hose is relatively short
and in good condition, the pressure drop between the compressor (or air receiver) and the
jackhamer should not exceed 15 percent of the initial pressure.
Low or inadequate air pressure at the jackhamer is costly and wasteful, and an insufficient
volume if air will not allow it to operate efficiently.
NOTICE
Proper lubrication is the most important single factor responsible for the service life of a
pneumatic jackhamer. A jackhamer 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 jackhamer 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.
