1.1.1 EN standards
Continuous sound level: 67 dB(A)
according to EN 12053 as stipulated in ISO 4871
The continuous sound level is a value averaged according to standard regulations, taking the
sound pressure level into account when driving, lifting and idling. The sound pressure level is
measured at the ear.
Electromagnetic compatibility (EMC)
The manufacturer confirms compliance with the limit values for electromagnetic emission and
interference immunity as well as testing of static electricity discharge according to EN 12895 and
the references to other standards contained therein.
Electrical or electronic components and their arrangement may only be modied after written
approval by the manufacturer has been obtained.

1.1.2 Conditions for application
Working condition requirements:
The walking, lifting and lowering devices, harness and components are IP55 dust and water-
resistant.
The truck's maximum operation altitude is up to 2000m.
Trucks can only be operated in adequately illuminated working areas to avoid injuries. In case
of insu󰀩cient light, an additional lighting equipment is needed to ensure that the driver can see
properly.
If you must travel on an incline, the gradients should be below A% at full load, or below B% without
a load.(For the value of A and B, refer to the Gradability in technical data)
1.1.3 Stability
Stability is guaranteed if your truck is used properly in accordance with its intended
purpose. Common reasons for a loss of truck stability include:
Emergency stops or sharp turns.
Driving with a raised load or a load handling device.
Turning the vehicle around on or driving across a slope.
Driving up or down a slope with the load pointing downhill.
Driving with a wide load.
Carrying a swinging load.
Driving near the edge of a ramp or up steps.
Tilting the mast forward while carrying araised load.
Driving on uneven surfaces.
Overloading the truck.
Carrying bulky loads in strong winds.
When carrying liquid, its centre of mass inside the container may shift due to inertial force (such as
when pulling away, braking or turning).
Wind loads
Wind forces can a󰀨ect the stability of a truck when lfting, lowering and transporting loads with large
surface areas .
Light loads must be especially secured when they are subjected to wind forces. This will prevent
the load from sliding or falling. Stop the truck in both cases .
