Product presentation
FARMA energy cutters make your work in the forest more efficient and consequently more
productive. Felling, gathering, cutting and loading everything from trees and brush to bushes
and stumps can be performed easily.
Trees are cut rapidly and the fixed blade is easy to maintain. The location of the centre of
gravity makes it easy to position the grapple directly by the root. The FARMA Energy cutter is a
combined grapple and felling head that is often used for clearing energy wood. It is simple to
istall, ad eplaes the gapple loade’s egula gapple tool. The FARMA Eeg utte is

1. SAFETY REGULATIONS
We understand your desire to get started with your FARMA Energy cutter as
quickly as possible. In order to avoid unwanted operational stoppages or, in
the worst case scenario, hazardous situations, please acquaint yourself first
with the machine's functions and its safety instructions.
For your safety, it is extremely important that you follow the instructions
presented in this instruction manual.
Follow the safety regulations relating to the correct safety equipment and work clothes.
The energy cutter may only be used when all the safety devices have been checked and
protection is in place.
Check that no unauthorised persons are within the safety distance of 45 m when using the
cutter.
Only wear clothing that is appropriate for the work. Loose-fitting clothes can entail a
considerable risk of becoming caught while working.
There is always a risk of slipping when working with the cutter. Watch out for the blade's
cutting edge and always maintain your distance from the cutter head.
When the work is complete, the cutter must always be parked folded up on the ground or the
trailer.
Always pay attention when working close to electrical cables. Maintain
a safe distance. Bear in mind the risk of unforeseen movements. If the
cutter should come into contact with a power line for any reason:
Warn people in the vicinity of the crane/cutter not to touch the
machine;
Do not touch any metal parts;
Remove the crane's arm system or cutter from live cables.

Forbidden to raise or lower the cutter before the
log is cut off!
It is important that you adjust the speed as you approach the log and will clamp around the
tree. Approach always the material to be cut so that the felling head is at 90 degree angle to
the log. Once you started the cutting movement, one must not raise or lower the cutter before
the log is completely cut off. To shake the cutter up and down will risk the knife and the jaws to
unanticipated stress and risk of breaking.

It is absolutely prohibited to stand under a raised machine!
Note: To reduce the risk of injuries, always keep the cutter's grapple arms outside of the blade
when the cutter is not in operation. See figure below.

3. GENERAL DESCRIPTION
Principal components and functional devices
The energy cutter comprises the following principal components and functional devices.
The cutter is mounted with the flange plate
(diameter 49 or 59 mm) directly on the
rotator shaft in the same way as a normal
grapple. It is possible to flange the rotator
directly onto the BC18, without a flange plate.
Tilt cylinder
This is illustrative photo to describe cutter components
The cutter tilts down automatically when the stem or stems
have been cut off and the pressure in the grapple cylinder
reaches a factory preset value.
Similarly, the cutter tilts back up automatically to the cutting
position when the grapple claws are opened fully.
