WARNING!
- DISCHARGE OF HOT HYDRAUILC OIL
The hydraulic system is under high pressure. If the hydraulic
connections loosen or become disconnected, the hydraulic
oil will spray out under high pressure. This can lead to serious
injury.
Ø
Ensure the pressure in the hydraulic system is released
before connecting or disconnecting the demolition and
sortin grab.
ATTENTION
- ENVIRONMENTAL CONTAMINATION BY HYDRAULIC OIL
Hydraulic oil is harmful to the environment. When hydraulic
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. 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.
4.1 Hydraulic fluids
The following fluids must be used for the demolition and sorting
grab.
4.1.1 Mineral hydraulic oil
All hydraulic oils indicated by the excavator manufacturer can
also be used for the demolition and sorting grab.
◊
The oil must meet viscosity class HLP 32 or higher.
◊
In the summer and in hot climates, oils with viscosity class
HLP 68 or higher must be used.
◊
In all other cases, the specifications of the excavator
manufacturer must be taken into account.
Other conditions apply when used at lower ambient
temperatures. More information is provided in the section
entitled Low ambient temperatures.
◊
Inspect the oil filter regularly!
An oil filter must be fitted in the return line of the hydraulic
system. The maximum allowable mesh size is 50 microns. It must
also be fitted with a magnetic separator.
4.1.2 Non-mineral hydraulic oil
ATTENTION
- MIXED HYDRAULIC OIL
Never mix mineral oil with non-mineral oil. Even small traces of
mineral oil mixed with non-mineral oil may result in damage to
both the demolition and sorting grab as well as the excavator.
Non-mineral oil loses its biodegradability.
Ø
Use only one type of hydraulic oil.
If non-mineral oil is used, the brand must be indicated when the
demolition and sorting grab is brought in for repair.
To protect the environment, or for technical reasons, the
hydraulic oils currently used are not classified as HLP mineral oils.
In principle, the demolition and sorting grabs from Dehaco B.V.
are designed for use with mineral oils. Contact Dehaco B.V. before
deciding to change to non-mineral hydraulic oil.
4.1.3 Grease
◊
Observe the safety regulations before working with oils and
greases.
4.2 Attaching to the excavator
A colleague’s help is required to attach the demolition and sorting
grab to the excavator.
◊
Agree on hand signals to use with your colleague to enable
them to assist in correctly positioning the excavator on the
demolition and sorting grab.
◊
Lower the arm of the excavator to position it in the adapter
plate holder.
WARNING!
- INJURY FROM SUDDEN MOVEMENTS OF THE EXCAVATOR ARM
A sudden movement by the excavator can strike your colleague
and cause serious injury.
Ø
Move the excavator arm carefully and in a controlled manner
when someone is in the danger zone.
Ø
Ensure your colleague always remains visible.
WARNING!
- CUTS OR INJURIES TO HANDS AND FINGERS
Drilled holes and surfaces may be razor sharp and cause serious
injury.
Ø
Never use your fingers to inspect holes or mounting surfaces.
If a pin and bushing system, follow the procedure outlined below.
If another (quick change) system is being used, we recommend
consulting the manufacturer’s manual.
◊
Follow the directions provided by a colleague to properly
align the holes in the adapter plate (B) and the excavator arm
(A).
◊
Install and secure the hinge pin (C).
◊
Raise the demolition and sorting grab.
◊
Extend the bucket cylinder (E) until the securing hole in the
coupling (F) aligns with the securing hole in the adapter plate
(B).
◊
Install and secure the coupling pin (G).
◊
Carefully move the bucket cylinder (E) to both end positions.
