Preface
From now on, you can get your loader even wider deployed using the WLA60.
This hydraulic arm makes it possible to mount a Becx hedge cutter to your loader. The WLA60 is
designed to fit onto almost any loader. If your loader does not have the two required double-acting
hydraulic valves, Becx can offer you valves + a control box-set as an option. The WLA60 is 60cm
extensible and offers a 105 degrees tilt. The arm can be used left or right and can be mounted to the
front or rear of your machine. Combined with the lift of your wheel loader this allows you cut nearly
every hedge. The WLA60 can carry our HS130HR and HS150HR hedge cutters, and even our new
HS131HR hedge cutter.
Carefully read this manual before using the loader arm. Always
follow the safety instructions set out in chapter 3.
One copy of this manual must be kept with the loader arm 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
loader arm and its tools and for ensuring that the loader arm and
tool is properly attached and connected.

2. Safety
2.1. General
No modifications must be made to the loader arm.
The user is responsible for making sure that the correct loader and adapter
are used (see chapter Fout! Verwijzingsbron niet gevonden.). The following
re 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 tool carrier must be strong and stable enough to absorb the forces and
moments exerted by the loader arm 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 loader arm 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.
Persons or animals who are present in or who approach the danger zone must
be stopped immediately and the weed brush must be switched off.
If passers by disrupt the work too much, the operator can consider
temporarily cordoning off the site.
If the loader arm starts to make a different sound and/or starts to vibrate,
work must stop immediately and the weed brush has to be switched off. Work
can only continue after the source of the noise has been identified and
resolved.
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 loader arm 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).

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.

to one single-acting hydraulic function to two double-acting
functions and a single-action function.
5
Cylinder to rotate
By using this cylinder the tool will be rotated up to 110
degrees. This can be used to switch between the cutting on
top, or on the side of the hedge.
6
Base
This section is the base of the arm. This connects all the
components together.

acting electric functions. By default, the machine is delivered without
valve block, but with the necessary hydraulic fittings and hoses supplied.
See the supplied electrical and hydraulic diagrams for your model.
It is the responsibility of the user to link the machine in the right manner
to the tool and loader.
