Improper operation can result in excess or uneven working tool wear, which could necessitate early replacement.
These simple tips can help you get more life and performance from hydraulic breaker attachments.
- Make sure the operator understands proper breaker operation and what to look for during daily visual inspections.
- Properly match the breaker's hydraulic flow/pressure requirements to the carrier.
- Reposition the tool every 15 to 30 seconds until the material breaks. Maintain down pressure on the breaker as it breaks through the material.
- Lubricate the breaker regularly to prevent damage to tool bushings.
- Remove the breaker bit weekly and check for tool shank wear. Galling may occur from lack of lubrication.
- Use auto lube systems where possible.
- Operate the breaker with the tool suspended in the air (blank firing).
- Continue to hammer in one spot of the material for too long. This can generate excessive heat, which can result in tool breakage and/or damage to the breaker.
- Start breaking large objects or slabs from the center of the material. Start at the outer edges and work your way inward.
- Use the breaker for prying or raking. This can cause tool point breakage.
- Run a breaker underwater without the proper underwater kit on the excavator. This can lead to contamination of the carrier's hydraulic system.
- Neglect any concerns the operator may report about breaker performance or wear.
