A Hydraulic Hammer is one of the most important tools on any demolition or construction site. It does the heavy work, breaks hard material and keeps the project moving. When a Hammer is set up correctly, the excavator works smoothly, the job gets done faster and the attachment lasts longer. When the setup is wrong, the Hammer loses striking power, overheats or wears out parts much sooner than expected.
Most issues that reduce Hammer performance do not come from faults in the attachment. They come from simple setup mistakes. These mistakes are common across sites in the UK and can easily be avoided with the right checks. This guide explains the most frequent setup errors and how contractors can fix them to get the best output from their Hydraulic Hammers.
The most common problem seen with Hydraulic Hammers is incorrect flow. If the flow is too low, the Hammer feels weak and slow. If it is too high, the Hammer overheats and damages internal seals. Getting the flow right is essential for safe and efficient operation.
Correct flow settings protect both the Hammer and the excavator. This simple adjustment keeps the tool working at its best and reduces long term wear.
The tool (chisel or moil) is the part that makes direct contact with the material. If it is worn out, the Hammer loses breaking efficiency. If the tool diameter is wrong for the Hammer body, the movement becomes unstable and the bushings wear quickly.
A sharp, correctly sized tool increases impact efficiency and improves production output on site.
Hydraulic Hammers require the right type of grease and correct lubrication intervals. Using the wrong grease or not greasing the tool enough causes premature wear, high temperatures and bush failure.
Good lubrication extends the life of the tool, the bushings and the entire Hammer.
One of the most damaging operator habits is holding the Hammer in one place for too long. This creates high heat, damages the piston and reduces output.
A simple change in operator technique can greatly increase the Hammer’s performance and reliability.
Hammers must be matched to the excavator. A Hammer that is too small reduces productivity. A Hammer that is too large puts stress on the excavator and causes premature wear.
Using the correct size Hammer keeps the machine stable and improves breaking speed.
If the mounting bracket is not aligned properly, the Hammer will vibrate in the wrong direction. Loose pins or worn bushes create movement that reduces efficiency and puts stress on the excavator.
A secure mounting system helps the operator maintain full control during breaking.
A Hydraulic Hammer is designed for specific types of material. Using it in the wrong application reduces performance and damages internal parts.
Correct application ensures the Hammer works efficiently without unnecessary strain.
Back pressure from the excavator affects Hammer speed and impact power. High back pressure reduces performance instantly.
This simple check protects the Hammer from internal damage and keeps performance consistent.
Small symptoms can develop into bigger problems if not noticed. Contractors often overlook these signs during busy working days.
Addressing small issues early saves time and keeps the job flowing smoothly.
Many performance issues come from operators who have not been trained properly. Even experienced excavator drivers may not know the correct Hammer techniques.
Better trained operators deliver faster breaking and safer working conditions.
Where TocDem fits in
TocDem supplies the TEB Hydraulic Hammer range, which is tested, serviced and set up to perform correctly from day one. Each unit is checked for hydraulic compatibility, tool condition, flow requirements and bracket fitment before it leaves the workshop. Contractors also have access to TocDem support for advice, servicing and spare parts.
Working with a supplier that understands real site conditions helps contractors get better output from their Hydraulic Hammers every day. TocDem focuses on reliability, correct setup and practical support that keeps projects moving.
Hydraulic Hammer performance depends on correct setup, not just build quality. Simple mistakes with flow, tool condition, lubrication and operator technique reduce impact power and slow down site progress. These issues are easy to avoid with a few practical checks.
Contractors who follow these steps get more breaking power, longer tool life and fewer delays. A well set up Hammer delivers better value, helps complete work faster and keeps the excavator running smoothly.
