Eight Tips for Efficient Komatsu Hydraulic Breakers

This guide covers eight crucial rules for operating hydraulic breakers, including avoiding blank firing, proper use, safe operation, protecting cylinders, cold weather procedures, moving the tool frequently, avoiding overheating, and preventing water immersion.

Step 1 of 9

Blank Firing

Avoid Blank Firing

Blank firing occurs when there is no object to absorb the breaker's force.
It causes extensive wear and tear to the tool and components.
To prevent blank firing, stop the breaker before the material separates.

Step 2 of 9

Appropriate Use

Use Breakers for Intended Activities

Not all breakers are designed for maneuvering rocks.
Check with the manufacturer for specific uses.
Breakers for rocks usually have a rock hook or protective structure.

Step 3 of 9

Safe Operation

Avoid Lifting or Prying

Do not use the tool or breaker to lift or pry.
It’s dangerous and can damage the breaker, tool, and bushings.

Step 4 of 9

Excavator Cylinders

Protect Excavator Cylinders

Do not allow the excavator cylinders to reach the end of their stroke.
This position does not tolerate breaker vibrations well.

Step 5 of 9

Cold Weather Operation

Warm Up in Cold Weather

Always warm up your equipment properly before operating in cold weather.
Store the breaker inside during extremely low temperatures.

Step 6 of 9

Move the Tool

Move the Tool Frequently

Move the tool to new positions often.
This helps avoid powder buildup under the tool and improves shock wave travel.

Step 7 of 9

Avoid Overheating

Limit Time on One Spot

Never let the breaker strike the same spot for more than 15 seconds.
Prolonged use in one spot causes heat buildup, reducing tool strength and wear resistance.

Step 8 of 9

Water Immersion

Do Not Immerse in Water

Do not immerse the breaker in water or mud to a depth where the tool is not visible.
For underwater use, contact your dealer for an air pressurization kit.
