1.6 Transport, precautions
WARNING!
- FALLING SUPPORT
If the load-bearing capacity of the excavator is not sucient,
it will not be stable when using the demolition and sorting
grab. The excavator could tip over and cause injury.
Using an excavator with excessive load capacity will cause
excessive load on the demolition and sorting grab resulting
in increased wear.
ØOnly attach the demolition and sorting grab to an
excavator with suitable capacity.
ØThe excavator must always remain stable.
ØRead this manual thoroughly before attaching and using
the demolition and sorting grab.
1.7 Hydraulic equipment, precautions
WARNING!
- EXCESSIVE HYDRAULIC PRESSURE
Excessive hydraulic pressure overloads the components
of the demolition and sorting grabs. This may cause
components to break or crack resulting in serious injury.
ØInsert the discharge tube of the pressure relief valve
directly in the tank to ensure safe operation!
ØThe pressure relief valve must be set to the maximum
static pressure.
ØThe settings for the pressure relief valve must be checked
to ensure the maximum static pressure of the hydraulic
system (see Technical Specications section) is never
exceeded. Apply a lead seal to the pressure relief valve.
ØPrior to the rst use, the safety devices on the hydraulic
system must be inspected for their quality, suitability
and performance by a professional/approved inspection
agency (CE marking, etc.)
ØWhen any signicant changes are made to the hydraulic
system, an acceptance inspection must be carried out in
accordance with the relevant national safety regulations.
WARNING!
- DISCHARGE OF HOT HYDRAULIC OIL
The hydraulic system is under high pressure. Hydraulic
lines may leak or burst. Discharge of hydraulic oil can
cause serious injury.
ØWhen attaching the demolition and sorting grabs, no
hydraulic lines are to be laid through the excavator cabin
ØOnly use hydraulic lines that meet with the following
quality requirements:
-For the Open and Close functions:
§Hydraulic hoses with 4 reinforcing steel cables in
accordance with DIN EN 8566 4SH.
§Hydraulic tubes; seamless cold drawn steel
tubes in accordance with DIN EN 10305.
-For the Rotate function:
§Hydraulic hoses with two steel braids in
accordance with DIN EN 853 2SN.
§Hydraulic tubes; seamless cold drawn steel
tubes in accordance with DIN EN 10305.
1.8 Consumables, precautions
WARNING!
- HOT, HIGH PRESSUSE HYDRAULIC FLUID
A leak in the hydraulic system will cause hydraulic oil to spray
out under high pressure. The oil stream can penetrate human
skin and cause permanent injury. Hot hydraulic oil can cause
burns.
ØNever use your hands to locate leaks.
ØAlways keep your face away from a potential leak.
ØIf hydraulic oil has penetrated your skin, always consult a
physician immediately.

ØEnsure no hydraulic oil is spilled.
ØWhen hydraulic oil has spilled, clean the oor
immediately.
ØObserve all regulations regarding safety and
environmental protection when using hydraulic oil.
