Short answerGrease the chisel every 2 hours with the chisel pressed down, check through-bolt and hose tightness daily, check nitrogen pressure and bushing wear weekly, change the excavator hydraulic oil and return filter at the intervals for breaker use (more often than bucket work), and replace seals at least once a year.
Daily (every shift)
- Grease the chisel bushing every 2 hours, with the breaker standing on the chisel so grease reaches the gap.
- Check hoses and fittings for leaks and chafing.
- Check through bolts, side bolts and bracket bolts for looseness.
- Inspect the chisel for cracks and mushrooming.
Weekly
- Check the nitrogen (back-head) pressure with the charging kit.
- Measure clearance between chisel and lower bushing; replace when it exceeds the limit in the manual.
- Check retaining pins and stopper pins.
Hydraulic oil and filters
Breaker work heats and contaminates oil faster than digging. Use a return filter, keep oil temperature within the machine’s limits and change oil and filters more frequently than for bucket-only work.
Every 600–1,000 hours or annually
- Replace the seal kit and inspect piston and cylinder for scoring.
- Replace accumulator diaphragm (if fitted).
- Re-torque through bolts to the specified value.
Five mistakes that kill breakers
- Blank firing – running the hammer without the chisel on the material.
- Using the breaker to pry or lift.
- Breaking continuously for more than 30 seconds in one spot.
- Running under water without an air-supply kit.
- Skipping grease.
Storage
Store the breaker vertically, chisel removed and greased, nitrogen released, hose ends capped. We supply a printed manual and seal kits for every model; spare parts ship from stock.
