EDER splitting device EHG80, 07.12.09 - 1 -
Technical Data
Splitting way (range) 200 mm
Wedge length 180 mm
Wedge strength 120 mm
Laceration in diagonal position up to 220 mm
Pressure at the wedge 7,500 kg
Weight of the splitting device 16 kg
Required oil pressure 150 bar
Required oil flow from 10 l / min
Areas of Application
The device is apt for splitting trunks regardless of length and diameter. The wedge is
driven into the trunk through the oil cock from the shell, while the counterpoise is
absorbed by the diagonal edge penetrating into the face surface of the trunk. With
fibered wood and long trunks, the device can be applied diagonally. So the crack can be
widened to 220 mm width at any frequency.
Connecting the Splitting Device to the Hydraulics
For assembling the splitting device to tractors, unimog or hydraulic aggregates, 2
hydraulic connections are required. It is to be observed that a connection should be
unpressurized (R = return). The other connection (P = pump) is inserted at the pressure
line.
There are various hydraulic systems on the market. At purchase, the hydraulic system to
which the splitting device is to be connected must be named to the manufacturer, so the
corresponding valves are assembled to the device. With hydraulic systems with
adjustable feed pump, an oil flow of 20 l/min is to be adjusted. At this flow rate, optimal
performance of the splitting device is achieved.
Instructions for Use
The front and back range of the wedge can be controlled via the control valve attached to
the handhold. The hose connexion serially 10 m long between the hydraulic drive and the
splitting device gives a sufficient scope of movement for the person operating the device.
By using the splitting device, splitting long or fibered trunks is essentially facilitated and
accelerated. The pieces to be split are trenched once or repeatedly lying in their
respective position at the bottom according to requirements. This device is also apt for
splitting up treetops.

Protection from Accidents
The device may only be applied in the positions
indicated in the two pictures. Applying the wedge
to the cutting area of the trunk can lead to
breaking the device.
The safe state of the machine is to be checked
each time before beginning to work.
If the splitting device is temporarily not used, the
hydraulics are to be turned off, or the device is to
be deposited in a safe position, so accidental ac-
tuation is excluded.
The hydraulic pressure of 150 bar preset in
the pressure control valve may not be
increased.
A safe stand is to be ensured at work.
At a hillside situation, it is to be worked from
the mountain side. The danger of trunk halves
falling apart is to be observed.
An oil jet pouring out at high pressure penetrates unprotected skin and damages it.
Therefore, on suspicion of being leaky, the device may not be scanned with bare hands.
Instructions for maintenance
Only original EDER spare parts are to be used for replacement of defective parts.
Instructions for the Use of Personal Protective Equipment
The service personnel must wear equipment for the protection of the body, especially
including eye and face protection, ear protection, protective gloves and protective shoes.
Further help
If you have any questions about installation, commissioning, and application security, or
even in case of a fault, please call your local dealer and of course us as the manufacturer
by phone or e-mail. Our contact details can be found on the first page of this guide.
