OPERATION

EACH DAY

•Check for loose or missing fasteners. Tighten or re- place as needed.

•Inspect tool retaining pins and pockets for wear.

•Check for hydraulic leaks at all fittings and hoses. Replace any defective hoses.

•Apply grease to the grease fitting in the lower body each morning. Grease as needed throughout the work day.

•Inspect the lower bushing, tool retainer, tool retainer pins. Reseat or replace if necessary.

TOOL STOP & LOWER BUSHING

Inspect the tool stop, and lower bushing for excessive galling and metal pickup on the tool bit. Also check for cracks. If cracks are present, the parts must be replaced.

The extent of wear of the tool stop and lower bushing and the tool bit can be checked by moving the tool bit back and forth and measuring the gap between the tool bit and the lower bushing. If the gap is more than 0.354 in./9 mm the tool stop, lower bushing, and the tool bit should be replaced. A gap in excess of 0.354 in./9 mm will cause damage to the piston. Do not just replace the tool bit or the lower bushing individually as this will result in premature wear of the replaced component. It is rec- ommended to replace all worn components.

PERIODIC MAINTENANCE CHECKS

•Periodically check wear pad clearance by moving the power cell back and forth. Set the breaker on the bit and then use the excavator to move it from side to side as shown in the illustration. If the deflection exceeds 1.5 inches, replace the wear pads.
