5.1 Delivery and Transport
Delivery
Check the Edge milling machine for visible transport da-
mage after delivery. If you discover any damage to the
Edge milling machine, immediately report it to the trans-
port company or the dealer.
Transport
Improper transport is accident-prone and can cause da-
mage or malfunctions for which we do not grant any liabi-
lity 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 disturban-ces
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 essential.
Transport with a forklift / pallet truck:
The edge sanding machine can be transported with a
forklift or pallet truck if it is firmly mounted on a pallet.
Transport with a crane:
Step 1: Attach 2 ropes with sufficient carrying capacity to
the crane hook and to the points of the edge
grinding machine suitable for transport.
Step 2: Carefully lift and transport the edge sanding ma-
chine with the crane.
5.2 Packaging
All packaging materials and packaging aids used by the
Edge milling machine are recyclable and must always be
recycled.Packing components made of cardboard are
crushed to waste paper collection.
The foils are made of polyethylene (PE) and the uphol-
stery parts made of polystyrene (PS). You can hand over
these substances to a recycling center or to the disposal
company responsible for you.
The packaging material must not get into the hands of
children, as some plastic packaging may present a suf-
focation hazard when used as a toy.
WARNING!
Severe or fatal injuries may occur if parts of the
machine tumble or fall down from the forklift
truck, pallet truck or from the transport vehicle.
Follow the instructions and information on the trans-
port box.
Note the total weight of the machine. The weight of
the machine is indicated in the "Technical data" of the
machine. When the machine is unpacked, the weight
of the machine can also be read on the rating plate.
Only use transport devices and load suspension gear
that can hold the total weight of the machine.
WARNING!
The use of unstable lifting and load suspension
equipment that might break under load can cause
severe injuries or even death. Check that the lifting
and load suspension gear has sufficient load-bea-
ring capacity and that it is in perfect condition.
Observe the accident prevention regulations issued
by your Employers Liability Insurance Association or
other competent supervisory authority, responsible
for your company.
Fasten the loads properly.
WARNING: DANGER OF TIPPING
The device may be lifted unsecured by a maximum
of 2cm.
Employees must be outside the danger zone, the
reach of loads.
Warn employees and, if necessary, advise employ-
ees of the hazard.
