Preface
The Becx hedge trimmer has been specially developed to cut hedges safely and efficiently.
Each cutting head is equipped with a double row of cutter blades, enabling extra fine cutting.
Combined with the five-sided protection, this prevents danger from flailing branches. The hedge
trimmer is designed in such a way that it will continue to function in the most demanding situations
and will continue to work for a long time. Each cutter head is therefore equipped with its own
hydraulic motor. The shafts and the bearings are of an extra heavy-duty construction.
Read this manual carefully before you start to use the hedge trimmer.
Always follow the safety instructions set out in chapter 2.
One copy of this manual must be kept with hedge trimmer and must
be available to the user. All important servicing sessions and any
comments must be recorded and retained by the servicing company.
The user is responsible for selecting a suitable tool carrier for the
hedge trimmer and for ensuring that the hedge trimmer is properly
attached and connected.

2) Safety
2.1 General
No modifications must be made to the hedge trimmer.
Only cutting blades that comply with the supplier's specifications must be
installed.
You are at risk of being cut by the sharp knife edges when you work on the
cutter blades.
The user is responsible for making sure that the correct tool carrier and lifting
arm are used (see chapter 0:1). The following are important points in this
regard:
The maximum pressure and number of revolutions (oil flow) must not be
exceeded. Excess pressure and excess revving can damage the machine and
cause injury.
The lifting arm and tool carrier must be strong and stable enough to absorb the
forces and moments exerted by the hedge trimmer safely and under all
circumstances.
2.2 In use
Consult the tool carrier manual for the noise rating. Because this is
considerably louder than the hedge trimmer itself, the noise load of the tool
carrier determines the rating.
The machinery must only be used for the activities for which it is designed.
The trimmer is not suitable for trimming with ground contact. The design of
the hedge trimmer means that there is too great a risk that the cutter blades
will touch the ground and/or obstacles.
The hedgecutter is built for cutting hedges and groundcover plantation and
must not be used for any other purposes such as cutting grass or road-sides.
Persons or animals who are present in or who approach the danger zone must
be stopped immediately and the hedge trimmer must be switched off (see
4.1). This also applies to situations where the hedge trimmer is switched on
after maintenance to make sure it operates correctly.
If passers-by disrupt the trimming work too much, the operator can consider
temporarily cordoning off the site.
The work-place should be secured when the operator’s sight is diminished by
a high or dense hedge.
If the hedge trimmer starts to make a different sound and/or starts to vibrate,
work must stop immediately and the hedge trimmer has to be switched off
(see 4.1). Work can only continue after the source of the noise has been
identified and resolved.

If no trimming work is being done, always switch off the hedge trimmer. This
includes when you are driving to the work site. The risk of coming into contact
with passers-by is greater at these times than during trimming. There is no
hedge present to act as a protective shield in these situations and it is more
difficult for bystanders and passers-by to judge the route you are taking.
Objects that are flung out can travel a greater distance when there is no
hedge to stop them.
Always complete inspection and maintenance jobs.
The machinery must not be used for any other purposes during inspection and
maintenance.
The hydraulic feed to the hedge trimmer must be disconnected during
inspection, maintenance or cleaning to prevent accidental operation.
Always comply with local work regulations and safety rules.
If the machinery is used in the dark, use sufficient lighting (approx. 50 lux at
the work site).
Trimming operations must stop immediately if there is any possibility that
people and animals could enter the danger zone. (see 4.1)
Switch machinery on and off at a low revolution speed to prevent damage.
Depending on the tool carrier used, this means that the machine is running
stationary or at minimum flow.
2.3 Operating personnel
Operating personnel must be over 18.
Only persons who have received permission from the owner are allowed to
operate the system.
Persons must only carry out jobs for which they are trained. This applies to
both maintenance work and normal operations.
Personnel who operate equipment must be familiar with all possible
situations that could arise.
The owner or person in charge must be told if personnel operating machinery
identify faults or hazards or do not agree with safety measures.

1
Select the correct tool
carrier and lifting arm
make sure that the tool carrier and lifting
arm are sufficiently strong and stable for
the hedge trimmer (see chapter 0 for its
own weight , the load when lifting (Figure
8:1 / 8:4) and the exerted moment of the
lifting (Figure 8:2).
Make sure that the maximum pressure and
number of revolutions (oil flow) are not
exceeded.
Make sure that the correct rapid
attachment connections are installed for
the feed line, return line and drain line.
Make sure that the correct clasp is used.
Ignoring the stated
values can result in
damage to
equipment and
injury to persons.
2
Adjust the hedge
trimmer in the
horizontal position.
Depending of the deflection of the lifting
arm, the bottom (see Figure 8:5) of the
hedge trimmer will not be completely
horizontal.
Adjust the angle setting (see Figure 8:3) so
that the deck is suspended horizontally
when lifted upwards.
Trimming will work
best if the base of
the protective deck
runs parallel to the
level of the cutting
plane.
3
Connect the hoses
Connect the rapid attachment connections
for the feed line, return line and drain line
(see: Figuur ).

Switch on the
hydraulic system
Adjust the setting of the hydraulic
aggregate so that the maximum pressure
and number of revolutions cannot be
exceeded.
This will depend on the type of tool carrier
that is used. Please refer to the manual of
the tool carrier.
On the hydraulic system there are 3
numbered adjustment screws.
They have the following functions:
1. This screw regulates the speed of the
hedgecutter. This speed should be set
at 2500 rpm.
2. This screw secures the pressure on
the hydraulic motors. This is set at
200 bar.
4. This screw controls the time that the
knive disks use to stop. This is set to 5
seconds.
Screw 2 and 4 are set correctly at the factory.
These should not be adjusted!

What to do
Action
Result
1
Check the machinery
check the following points:
check the cutter blades:
The cutter blades must not be ground
back too far and must be in balance (see
0)
Check the cutter blades for damage and
cracks before starting, after 4 hours of
operation or immediately if the cutter
blades have come into contact with
materials that are different from what
they are intended to cut.
Visually check at least on a daily basis
whether the locking plates and locking nuts
of the cutter blades are in place.
Check whether the direction of rotation
corresponds to the arrow on the deck.
Check the number of revolutions of the
cutter blades.
Check whether the cutter blades run free of
vibrations.
If a defect is identified in one of the above
points, this must first be remedied before it is
allowed to put the hedge trimmer back into
operation.
Carrying on with
loose locking
nuts, cracked
cutter blades or
with a poorly
running or
excessively fast
system can
result in damage
to the
machinery
and/or injury to
the operator or
passers-by.
2
Check the site where
the work will take
place.
Check the hedge to be trimmed and the
surroundings for the following points:
Are there any obstacles which can be
damaged by the hedge trimmer or which
could cause damage to the hedge trimmer?
Are there any loose items such as dirt or
loose metal wires?
Check if there is people or animals in the
danger zone are
If there are lots of people passing by the
work-place should be secured.
If the sight of the operator is severly
hindered (for instance by high or dense
hedge) the work-place should be secured.
Operator needs to always be sure there are
no people on the other side of a high dense
hedge when cutting it.
Bear this in mind
when carrying
out the trimming
operation.
Remove any
loose items in
order to prevent
damage to the
hedge trimmer.
