Operation Guide
Pre-Operation Checks
Before you start your mini excavator, always check your hammer and machine. Look for leaks, cracks, or loose bolts on the hammer. Make sure the hydraulic hoses connect tightly and show no signs of wear. Check the tool shank and bushings for damage. If you see worn parts, replace them before you work.
Inspect the excavator’s fluid levels. Hydraulic oil, engine oil, and coolant should be at the right levels. Clean the area around the hammer and remove any dirt or debris. This helps prevent damage and keeps your tools working well.
Tip: Use proper lifting equipment when you move or service the hammer. This keeps you safe and protects your equipment.
Keep the operator’s manual close. You may need to check it for settings or troubleshooting.
Controls and Instrument Familiarity
You must know your excavator’s controls before you use the hammer. Each machine has its own layout. Learn where the main levers, pedals, and switches are. Find the controls for the hammer attachment. Some excavators have a special button or lever just for hammers.
Check the instrument panel. Look for warning lights or error codes. These can tell you if the hammer or excavator needs attention. Many new hammers have features like auto shut-off or vibration reduction. Learn how to turn these on and off.
Note: Always keep the operator’s manual nearby. It shows you what each control does and how to use the hammer safely.
Starting and Stopping
Start your excavator by following the steps in the manual. Warm up the engine for a few minutes. This helps the hydraulic oil flow well. When you are ready to use the hammer, make sure the area is clear.
When you stop working, follow these steps to reduce wear on your hammer and excavator:
Lower the excavator arms and attachments flat on the ground.
Stop the engine and remove the key or lock the keyless panel.
Engage the parking brake.
Move all controls to a neutral or locked position.
Avoid letting the engine idle for too long. This reduces wear on hydraulic hammers.
Use machines with auto idle or auto stop features if possible. These save fuel and reduce wear.
Inspect hammer parts like hose ends, ports, retaining pins, tool shanks, bushings, and hoses often.
Safety Reminder: Never leave the excavator running while you check or service the hammer.
Proper Use Techniques
Use your hammer the right way to make it last longer. Pick the correct size hammer for your excavator. Using the wrong size can cause damage. Keep the hydraulic flow and pressure within the limits set by the manufacturer.
Position the hammer at a 90-degree angle to the surface. Move the hammer often during use. This prevents the tool from getting stuck and reduces wear. Do not use the hammer as a pry bar. Only use it for breaking, not for lifting or moving objects.
Grease the hammer often. Steel parts rub together and get hot. Greasing every two hours, or more in tough jobs, keeps the hammer working well. Stick to the maintenance schedule. Check and replace bushings, do annual flow tests, and use sharp demolition tools.
If the hammer does not break material after 30 seconds, stop and try a larger hammer. Running too long without progress can damage the tool.
Bring the hammer to the shop once a year for a full check.
Using the right techniques and regular care helps your hammers last longer and work better.
Maintenance
Daily Maintenance
Check your mini excavator and hydraulic hammers every day. This helps you find problems early and keeps you safe. Walk around your machine before you start work. Look at the hydraulic cylinders, rods, and seals for leaks or damage. Check the hammer attachment and coupler for rust or cracks. Open the side hood and look at the hydraulic tank, hoses, and joints. Make sure nothing is leaking or loose.
Look at the fuel water separator for water. Check the cooling system for leaks and the right coolant level. Grease all pivot points on your hydraulic hammers to stop them from wearing out fast. Clean the engine area and make sure the oil cap is tight. Look at the belts for any signs of wear. Make sure fuel and hydraulic oil levels are what the manufacturer says. Clean the air filter every week, or more if it is dusty. Check the tracks for dirt and fix the tension if needed.
Tip: If you work where it is hot or dusty, check your machine more often. This helps your hammer and hydraulic hammers last longer.
Greasing Hydraulic Hammers
Greasing is very important for hydraulic hammers. Grease stops parts from rubbing too much and getting too hot. Use high-quality, high-temperature molybdenum grease or chisel paste with copper and graphite. These greases work well even when the hammer gets very hot.
Aspect | Details |
|---|---|
Grease Type | High-temp molybdenum grease or chisel paste with copper and graphite |
Greasing Interval | Every 2 hours, or more often in dusty or tough jobs |
Operating Conditions Impact | Grease more often in dry, dusty, or hot environments |
Greasing Technique | Hold the breaker vertical and apply down pressure to push grease into tool-bushing gaps |
Amount of Grease | Fill until grease comes out the bottom of the bushing |
Signs of Insufficient Grease | Overheating, shiny tool shank, or seizing bushings |
Benefits | Less friction, cooler operation, longer hammer life |
Grease your hydraulic hammers every two hours, or more if you see shiny spots or hear squeaks. If you use big hammers, you can use an auto-lube system for steady grease. Even with auto-lube, check the grease level by hand every few hours. Greasing the right way keeps your hydraulic hammers working well and stops costly repairs.
Filter and Oil Changes
Changing filters and oil keeps your hydraulic hammers and excavator in good shape. Old or dirty oil can hurt your machine and cause breakdowns. Follow the manufacturer’s schedule for oil and filter changes. Change engine oil and filters every 100 to 500 hours. Replace fuel filters every 500 hours or once a year. Clean air filters every week and replace them every 500 hours. Drain and refill hydraulic oil every 1,000 to 2,000 hours. If the oil looks dirty or you work in tough places, change it sooner.
Always use the oil and filters the manufacturer says to use.
Never mix oil brands unless you drain the old oil first.
Keep hydraulic hose ends clean so dust and sand do not get inside.
After about 600 hours, get a full service to check inside parts and keep everything working right.
Changing oil and filters on time helps your hydraulic hammers avoid downtime and last longer. This easy step saves money and stops big repairs.
Wear Parts Inspection
Wear parts on hydraulic hammers need careful checks. These parts are tool bushings, tool retaining pins, and the piston. Look at these parts every day for cracks, shiny spots, or wear. Listen for new noises or changes in how your hammer works. If you see damage, change the part right away.
Lubricate moving parts like bearings and joints to stop friction.
Check hydraulic systems for leaks, low fluid, or dirty oil.
Watch for changes, like slower hammering or more shaking.
Change your maintenance schedule if you work in dusty, wet, or cold places.
Using the right attachments and following the manufacturer’s plan helps your hydraulic hammers last longer. Preventive maintenance can make equipment work better by 30% and save 25% in five years. Skipping checks can lead to repairs that cost half as much as a new hammer in just weeks. Track your hours and follow your maintenance plan to avoid these problems.
Note: Checking your machine and using grease the right way protects the most expensive parts of your hydraulic hammers and keeps your work going.
Troubleshooting
Common Issues
You may notice some common problems when using hydraulic hammers and breakers. Leaks from hoses or fittings often signal trouble. Loose or worn parts can cause strange noises or weak performance. If your hammer does not break material as fast as before, check for worn bushings or tool shanks. Sometimes, the breaker may trip or stop working if you run it too long without progress. Exceeding 20 blows per inch of pile penetration means your hammer might be too small for the job. This can damage both the hammer and the excavator. Always inspect for leaks and check hose and fitting conditions before you start work. Daily walkaround inspections help you catch fluid leaks or irregular noises early.
Tip: Use monitoring technology like KOMTRAX to track equipment health and get alerts for potential issues.
Oil Pressure and Flow
Hydraulic hammers and breakers need the right oil pressure and flow to work well. Low oil pressure can make the hammer hit weakly or not at all. High pressure can cause overheating or damage. If you notice slow hammering or more shaking, check the hydraulic oil level and quality. Dirty oil or clogged filters can block flow and hurt your hydraulic breakers. Always keep hydraulic oil clean and at the right level. Avoid running the hammer below 38 blows per minute for long periods. This can shorten the life of your hydraulic hammers and breakers.
Check for leaks in hoses and fittings.
Make sure fuel lines do not touch the hammer body except at the ends.
Use the two-wrench tightening method to avoid leaks or premature failures.
When to Seek Service
You should seek service if you find cracks, leaks, or worn parts during your checks. If you hear new noises or see a drop in performance, stop and call a technician. Inspect mounting hinges, bucket components, retaining pins, and tools every week or every 10 work hours. Check tool shanks, bushings, and hydraulic hoses every month or every 50 work hours. Service your hammer every year or after 600 work hours to keep it working well. Never ignore warning lights or error codes on your excavator. If you cannot fix a problem with basic checks, let a professional handle it. This keeps your hydraulic hammers and breakers safe and reliable.
Note: Regular inspections and timely service prevent costly repairs and keep your equipment running strong.
