WARNING!
- DISCHARGE OF HOT HYDRAULIC OIL
The hydraulic system is under high pressure. If the hydraulic
connections loosen, the hydraulic oil will spray out under
high pressure. This can lead to serious injury.
Ø
Switch the excavator and demolition and sorting grab off
immediately if a leak is detected.
Ø
Release the pressure in the hydraulic system.
Ø
Repair any leaks before using the demolition and sorting
grab again.
WARNING!

The hydraulic cylinder, hoses, tubes and fittings become very
hot during operation. Contact with these components can cause
burns.

If works need to be completed on or near hot components,
wait for them to cool down first.

ATTENTION
- ENVIRONMENTAL CONTAMINATION BY HYDRAULIC OIL

oil is released (e.g. by leakage) the groundwater and soil may
become contaminated causing organisms to die.
Ø
Collect all spilled hydraulic oil to prevent environmental
contamination. For small amounts, use absorbent material
Ø
Ensure it does not make its way into the soil, groundwater
or water lines.
Ø
Collect the contaminated absorbent material in an airtight
container and seal it well.
Ø
Contact a licensed waste disposal company.
Ø
Remove all contaminated materials in accordance with
current environmental regulations.
