Cleaning, maintenance and checks
5.1 Cleaning
The hammer does not require particular care. The only precaution to take consists in preventing
the dirt from entering through the hose connections, which must be rigorously plugged before any
operation of assembly or disassembly.
5.2 Maintenance and daily checks
The machine needs some important maintenance, in order to work correctly and for a long time.
Greasing
The greasing operation, if done manually, must be performed every 2 hours in order to provide a
suitable quantity of grease. In case the hammer is supplied with an automatic greasing pump, it is
necessary to pay attention to the level of the grease inside the cartridge which must be replaced
before it is empty. If the hammer is connected to the excavator general greasing system, it is
necessary to pay attention to the level of the grease inside the tank.
Remember to use a type of grease, which must be:
- resistant to high loads.
- water resistant, anti-rust, anti-corrosive.
Have:
- NLGI-2 penetration
- Dripping point = 200-220 C°
- Temperature of use until t=170-180 C°
It is recommended to use possibly only Socomec grease for a longer life of the
parts.
Other checks to be made on the hammer
- Make sure that there are no oil leakages along the tool sank.
- Make sure that no cracks are evident on the frame or on the linking bracket.
5.3 Checks to be made on the hydraulic system
Temperature of the hydraulic oil in the tank
Make sure that the temperature, during the work, does not exceed 80°C.
Higher temperature can cause an irregular working condition and also the stopping of the hammer.
Level of the hydraulic oil in the tank
It is absolutely necessary to pay attention to the hydraulic oil level of the excavator tank. In case it
is under the lowest limit, the hammer can vibrate or work irregularly.
It is important to check the rigid and flexible hoses in order to find out eventual damages, crushing
or oil leaking.
Never operate on the hammer or on the hydraulic system, when they are under
pressure or at high temperatures.
It is always essential to remove the connecting hoses between the hammer and the
excavator.
