5 Transport, pac aging, storage
elivery
Check the Mobile sand-blasting unit after delivery for vi-
sible transport damage. If you discover any damage, re-
port it immediately to the transport company or the de-
aler.
Transport
Improper transport of individual devices, unsecured de-
vices stacked on top of each other or next to each other
in packed or already unpacked condition is accident-
prone and can cause damage or malfunctions for which
we do not grant any liability or guarantee.
Transport the scope of delivery secured against shifting
or tilting with a sufficiently dimensioned industrial truck to
the installation site.
General risks during internal transport
Devices may only be transported by authorized and qua-
lified persons. Act responsibly during transport and al-
ways consider the consequences. Refrain from daring
and risky actions.
Gradients and descents (e.g. driveways, ramps and the
like) are particularly dangerous. If such passages are
unavoidable, special caution is required.
Before starting the transport check the transport route for
possible danger points, unevenness and disturbances
as well as for sufficient strength and load capacity.
Danger points, unevenness and disturbance points must
be inspected before transport. The removal of danger
spots, disturbances and unevenness at the time of trans-
port by other employees leads to considerable dangers.
Careful planning of internal transport is therefore essen-
tial.
Packaging
All used packaging materials and packaging aids are re-
cyclable and should be taken to a materials recycling de-
pot to be disposed of.
The delivery packaging is made of cardboard, so please
dispose carefully by having it chopped up and given to
the recycling collection. The film is made of polyethylene
(PE) and the cushioned parts of polystyrene (PS).
These materials should be taken to a collection point for
recyclable materials or to the local waste disposal com-
pany.
Storage
The Mobile sand-blasting unit must be cleaned thoro-
ughly before storing it in a dry, clean and frost-free env-
ironment.
