Suggestions for Efficient Operation of Hydraulic Breaker
1.Do not operate the breaker continuously in one spot for more than 20 seconds. Doing so will cause excessive heat that could mushroom the end of the tool. * For large rocks, start at the edge and work toward the center, breaking off small chunks each time. * Always keep the tool 90° to the surface of the rock to reduce side loading on the tool bushings. * If the rock or stone shows no sign of breaking within 20 seconds, reposition the breaker. * Breaking along a rock’s natural faults and seams makes breaking easier. * When breaking on a wall or steep incline, use a combination of the carrier’s stick cylinder and tilt cylinder to provide the necessary force to hold the breaker against the material. Always work the tool at 90° to the material being broken. * As down-force is applied on the breaker, the carrier will lift slightly indicating breaker tool is properly pressed onto the material.
2. The breaker should not be fired when the carrier’s boom hydraulic cylinders are fully extended or fully retracted.
The cylinders may be damaged from the breaker’s shock pulses.
3.When hydraulic oil temperature exceeds 158°F (70°C), stop breaking!
If the carrier’s operating temperature runs too high, it will actually decrease the breaking power. * Rake ONLY with breaker wear plate and reinforced rock claws. Do not use the tool to rake materials. * Push ONLY with breaker wear plate and reinforced rock claws.
4.End of Shift
If the breaker is not removed from the carrier at the end of the day, it should be left standing vertical with the tool pushed up into the breaker.
