How to Charge a Hydraulic Breaker: Full Guide from Huilian Machine

As the global construction and excavation industry grows, the demand for high-performance attachments like hydraulic breaker hammers continues to surge. Correctly charging a hydraulic breaker is one of the most essential maintenance tasks, ensuring optimal performance, extended service life, and safety on the job site. Huilian Machine, your trusted OEM supplier of excavator parts since 2005, details the professional approach to charging a hydraulic breaker in this comprehensive guide.

With product exports reaching over 90 countries, including the US, Canada, Germany, Italy, Russia, and more, Huilian’s expert technical team brings you everything you need to know about how to charge a hydraulic breaker safely and efficiently.

Understanding the Importance of Charging a Hydraulic Breaker

Hydraulic breakers rely on a precise balance of hydraulic oil and nitrogen gas pressure to deliver powerful impact energy. Regularly charging the breaker with the correct nitrogen pressure—using the right tools and methods—ensures consistent performance, minimal wear and tear, and protection from costly repairs.

At Huilian Machine, we've observed that improper charging or neglect can lead to reduced impact power, gas leakage, seal damage, and even piston failure. By learning how to charge a hydraulic breaker step by step, you protect your investment and gain the highest ROI from your equipment.

When Should You Charge a Hydraulic Breaker?

Recognizing when to charge is as important as the charging process itself. Every breaker model and brand (such as Furukawa, Soosan, Atlas Copco, Komatsu, and more, all supported by Huilian Machine) may have unique requirements, but common signs include:

- Decreased impact force

- Unusual vibration or noise

- Increased oil temperature

- Frequent breaks or downtime

Scheduled maintenance, as recommended by the manufacturer or your breaker OEM parts supplier like Huilian, should always include routine checks and recharging procedures.

Tools and Materials Required for Charging

Proper charging requires exact instruments and high-quality parts, both available from Huilian Machine:

- Nitrogen charging kit (pressure gauge, hose, valve adapter)

- Nitrogen gas cylinder (ensure purity and dryness)

- Correct seal kits and replacement parts for your breaker brand

- Wrench and suitable hand tools

- Safety gloves and goggles

Avoid using makeshift equipment or substitutions; using reliable OEM parts ensures safety and wrench-free operation.

Step-by-Step Guide: How to Charge a Hydraulic Breaker

Let’s detail how to charge a hydraulic breaker, following OEM best practices applicable to most brands.

Preparation for Charging

1. Place the breaker in a safe, level area—preferably on a workbench or attached to the excavator with the engine off and hydraulic pressure released.

2. Consult your breaker’s manual for the correct nitrogen pressure value (generally 16-18 bar but always refer to specifications).

3. Check all seals, diaphragms, wear bushings, and retainer bars for leaks or wear. Huilian recommends replacing any compromised components before proceeding.

Connecting the Charging Kit

1. Remove the protective cap from the gas charging (accumulator) valve on the breaker.

2. Attach the charging hose and appropriate adapter to the valve. Make sure the connection is snug to prevent leakage.

3. Connect the other end to the nitrogen cylinder, ensuring the pressure regulator is closed.

Charging the Breaker

1. Slowly open the gas valve on the cylinder and regulate the pressure to match the recommended value.

2. Monitor the pressure gauge carefully; do not exceed the specified pressure to prevent diaphragm or seal damage.

3. Once the correct pressure is reached, close the cylinder valve and allow the gauge to stabilize for several seconds.

Completing the Process

1. Carefully disconnect the hose from the breaker valve to prevent gas loss.

2. Reinstall the protective cap and clean any residual oil or dust from the area.

3. Start the excavator (if installed) and briefly operate the breaker to ensure proper function.

Following these OEM-approved steps ensures your breaker delivers peak performance and reduces maintenance costs.

How to Charge a Hydraulic Breaker: OEM Tips and Safety Measures

Proper charging doesn’t end at the gauge. At Huilian, we provide the following professional tips to all our global distributor partners:

- Only use dry, pure nitrogen—never compressed air—as it prevents corrosion and maintains stability.

- Inspect all seal kits, diaphragms, and liner conditions during charging. Replace with Huilian OEM parts if needed.

- Avoid rapid gas release, which can cause freezing and damage to seals.

- Always use safety glasses and gloves to protect against high-pressure gas exposure.

- Maintain a charging history log for each unit to predict wear and schedule preventive maintenance.

Leveraging Huilian’s experience means your breakers last longer and perform better—maximizing uptime and profitability.

FAQs

What is the ideal pressure to charge a hydraulic breaker?

The correct pressure depends on the breaker model but is usually between 16 to 18 bar for most hammers. Always refer to the OEM manual for exact values.

Can I use compressed air instead of nitrogen?

No. Only pure, dry nitrogen should be used to charge a hydraulic breaker, as compressed air causes corrosion and erratic performance.

How often should I charge my hydraulic breaker?

Frequency varies by usage intensity, but regular checks (every 150–200 working hours) and after any significant maintenance are recommended.

What happens if I over-charge the breaker?

Overcharging risks damaging internal diaphragms, seals, and the breaker body. Always follow manufacturer-recommended values.

Where can I buy original seal kits and charging tools?

Huilian Machine supplies genuine OEM seal kits, valves, and charging equipment for all major breaker brands—contact us for details.

How do I know if my breaker needs charging or repair?

Reduced impact force, oil leaks, or unusual noise indicate the need for charging. If issues persist, consult a professional for inspection and repair.
