Product Range ▼ Paving Breaker KSC 1123
OPERATING AIR PRESSURE : Air pressure should be between 90 to 100 PSIg (620 to 689kPa) at the tool during operation. Use at higher pressures will increase recoil to the operator, decrease performance and output, and may cause damage to the tool. Lower pressure will also reduce tool performance. It is important to realize that the use of long lead hoses, manifolds and worn hose connections in the air line leading upto the tool will cause a pressure drop. Use couplings and fittings of maximum inner diameter for the size of hose being used (Refer to the specifications chart for this data). Reducers will restrict the air and therefore result in less pressure at the tool.

COMPRESSED AIR SUPPLY : Use an air compressor with sufficient CFM (Cubic Feet per Minute) delivery to operate the tool(s) at a pressure of 90 to 100 PSI (pounds per square inch), (620 to 689kPa). Refer to the specifications chart for CFM requirements.

AIR HOSE CONNECTION : Inspect air hoses, fittings and gaskets for cuts, abrasions and wear. Check that fittings, both in the tool and on the hose, are secure. Use
safety wire or chain to secure the couplings at the tool so as to prevent hose whipping, should the hose become detached while pressurized. Clear hoses of debris and excess water before attaching them to the tool. For hoses in excess of 1/2" inside diameter install a proper flow limiting valve per OSHA standards.

RECOMMENDED LUBRICATION PROCEDURE : The KSC-1123 series of Paving Breakers require minimal lubrication under normal operating conditions. Oil carry-over from the compressor, combined with moisture in the air, will not normally suffice to provide sufficient lubrication to this series of tools. The use of an external line lubricator in the air line between the
compressed air source and the tool is recommended. Use KSC-1.3 line oiler for this application A slight mist of moisture/oil should be present at the tool exhaust and on the shank of the steel. This is a sign of adequate tool lubrication. The KSC-1123 series of tools have an inbuilt oil chamber which has a 5 hour capacity.
A drill rod coupling lubricant should be applied to the shank of the steel. Please refer to the table on Lubrication for recommended lubricants.
