User’s Manual – A16 J A18 J Series Page 8
Any other use different than those for which it was designed must be approved in writing by the manufacturer following a
specific request on the part of the user.
Do not use the machine for purposes other than those for which it was designed, except after
making a request and having obtained written permission in this sense from the manufacturer.
1.3.1. Deboarding the platform off the ground
The risk of deboarding the Aerial Work Platform when the platform is off the ground has not been accounted in our
design safety because the only possible deboarding configuration is the one with the platform completely lowered on
ground. For this reason, boarding or leaving a raised platform is absolutely prohibited.
However, operators do happen to incur certain situations where they need to leave or access the platform in different
positions than the initial boarding one. These situations are commonly referred to as “Boarding the platform off the
ground”.
The risks relative to “boarding a platform off the ground” depend on the configuration of the platform, but also from the
risk assessment analysis carried out by the employer before authorizing any such condition. However, the following
circumstances should always be taken in due account:

Site/area characteristics;

Use of the machine as an anchoring point for other operators and other applications, which should be prevented
and never be possible for no reasons;
 Use of the machine at xx% of the its performance to prevent additional stress resulting from specific operations,
or flexural bending of the chassis which may force the platform away from the boarding area. In this case, it is
recommendable to perform a few trials and define these limit conditions;
 Implementation of a special emergency evacuation procedure (for instance having a man on the platform;
another one at the control station on ground, while a third one leaves a raised platform);

Administration of extensive training of the persons involved (both operators and passengers);

Installation of all implements needed at the point of boarding/deboarding to prevent falling of the persons
leaving the platform.
This paragraph should not be interpreted as a formal approval by the manufacturer to deboard the platform off-the-
ground, which remains a strictly prohibited action. The Employer is the ultimate person responsible for making any such
decision and this paragraph is merely meant to supply additional information and help.
1.4. Description of the machine
The machine described in this user's manual is a Mobile Elevating Work Platform equipped with:
 A motorized wheeled chassis;

A rotating, hydraulic turret;

A lifting system operated by means of hydraulic cylinders and joints whose number will change based on
machine type;

An operator platform (the max. capacity of which varies based on machine type - see chapter "Technical
features”).
The chassis is motorised to allow the machine to move (see "General use instructions"). All machines are available with
any of the following drive options:

Two driving wheels and two idle steering wheels; or
 Four driving wheels, out of which two are steering and two are fixed.
Moreover, all the above variants can be equipped with an optional full floating axle with locking differential.
All driving wheels are equipped with hydraulic parking brakes, positive logic type (when drive controls are released
brakes are automatically activated).
The turret is assembled on a turntable mounted to the chassis and can be stepwise rotated by 360° around the central
axle of the machine by means of irreversible endless screw.
The lifting system , with articulated boom, is composed of three main assemblies:

The first is a vertical assembly made of two “parallel four-bar linkages” called “crank arm” or “pantograph”.

The second is an articulated boom lift with telescopic extension.

The third is the jib which is the tip of the boom that extends out or telescopes.
