2. Designed purpose of use
The AVANT Leguan 50 Access platform is an attachment suitable for use with AVANT multi purpose loaders
shown in Table 1. The LEGUAN 50 is a mobile lifting platform for indoor and outdoor use and it is designed
and manufactured to be an attachment for AVANT compact loaders. The Leguan 50 is an access platform
intended to lift persons and their equipment needed in work. The use of the Leguan 50 as a lifting crane for
lifting objects is prohibited.
The access platform can be used only with Avant multi purpose loaders. Use with other
type or brand of machinery is prohibited. The access platform can be used with 400-700
series Avant loaders, when rear support legs have been installed.
During lifting operation, the access platform is supported by its own outriggers and the extra outriggers fitted
to the rear of the loader. The platform is controlled from the lifting platform, and the AVANT loader works as
the hydraulic energy supply for the platform. The stability of the platform is based on the rigid fixing of the
attachment to the loader, and because of this, the instructions concerning installation procedures must be
followed carefully. With the emergency lowering valves the platform may be lowered in case the loader engine
shuts off.
The LEGUAN 50 has been designed and built according to international safety and access platform
standards. Regular maintenance tasks can be performed by the operator. More demanding maintenance and
repairing work must be left to qualified professionals. Appropriate protective equipment and original spare
parts must be used for the maintenance.
Familiarise yourself with the manual's instructions regarding service and maintenance. Please contact your
AVANT retailer if you have additional questions about the operation or maintenance of the equipment, or if
you require spare parts or maintenance services.

3. Safety instructions for using the attachment
Please bear in mind that safety is the result of several factors. The loader-attachment combination is highly
powerful and improper or careless use or maintenance may cause serious personal injury or property
damage. Due to this, all operators must carefully familiarise themselves about correct use and the operator's
manuals of both the loader and the attachment before starting operation. Do not use the attachment if you
have not completely familiarised yourself with its operation and the related hazards.
Misuse, careless use, or using an attachment that is in poor condition, may cause
risk of serious injuries. Familiarise yourself with the controls of the loader, correct
coupling procedure, and the correct way to operate the attachment at a safe area.
Study especially how to stop the equipment in a safe manner. Read all safety
precautions carefully.
To ensure the safety of the access platform, the manufacturer has performed satisfactorily the static stability
tests according to section 6.1.4.2.1 in standard EN 280+A2 and the dynamic overload testing according to the
standard’s section 6.1.4.3.
Regardless of the safe design of the equipment, misuse, the lack of maintenance, or careless use may cause
serious personal injury or property damage. Due to this, you should carefully familiarise yourself with the
manuals of both the loader and the attachment before starting operation. Do not use the attachment if you
have not familiarised yourself with its operation and the hazards related to lifting of persons.
When using person-lifting equipment at work, additional safety procedures may be mandatory according to
local regulations. Such requirements may include, for example, forehand planning of lifting work and periodical
inspections of equipment used for lifting of persons. Local rules may also mandate a written permission from
the employer to operate the platform.
