Intended use
3 Intended use
The machine is sed excl sively for bending radii on profiles, pipes and solid
materials. It sho ld be noted that certain profiles or materials may req ire spe-
cial wheels that are not incl ded. Only profiles and materials may be proces-
sed with the rollers provided. Proper se also incl des compliance with all in-
formation in this man al. Any se beyond the intended se or otherwise is
considered mis se.

5.1 Delivery and Transport
elivery Check the machine for visible transport damage after delivery. If the machine
is damaged, it m st be reported immediately to the transport company or the
dealer.
Transport Improper transport is accident-prone and can ca se damage or malf nctions
for which we do not grant any liability or g arantee.
Transport the scope of delivery sec red against shifting or tilting with a s ffi-
ciently dimensioned ind strial tr ck to the installation site.
WARNING!
Severe or fatal inj ries may occ r if parts of the machine t mble or
fall down from the forklift tr ck, pallet tr ck or from the transport vehicle.
Follow the instr ctions and information on the transport box.
Note the total weight of the machine. The weight of the machine is indica-
ted in the "Technical data" of the machine. When the machine is npac-
ked, the weight of the machine can also be read on the rating plate.
Only se transport devices and load s spension gear that can hold the
total weight of the machine.
WARNING!
The se of nstable lifting and load s spension eq ipment that might
break nder load can ca se severe inj ries or even death. Check that the
lifting and load s spension gear has s fficient load-bearing capacity and
that it is in perfect condition.
Observe the accident prevention reg lations iss ed by yo r Employers
Liability Ins rance Association or other competent s pervisory a thority,
responsible for yo r company.
Fasten the loads properly.

General risks during internal transport
Devices may only be transported by a thorized and q alified persons. Act re-
sponsibly d ring transport and always consider the conseq ences. Refrain
from daring and risky actions.
Gradients and descents (e.g. driveways, ramps and the like) are partic larly
dangero s. If s ch passages are navoidable, special ca tion is req ired.
Before starting the transport check the transport ro te for possible danger
points, nevenness and dist rban-ces as well as for s fficient strength and
load capacity.
Danger points, nevenness and dist rbance points m st be inspected before
transport. The removal of danger spots, dist rbances and nevenness at the
time of transport by other employees leads to considerable dangers.
Caref l planning of internal transport is therefore essential.
Transport with a forklift / pallet truck:
For shipping, the machine is firmly mo nted on a pallet so that it can be trans-
ported by forklift or pallet tr ck.
Transport by crane:
The machine can be set p with a crane in a s itable location. To do this, the
machine m st be attached to the crane in accordance with the reg lations
(Fig. 4). The attachment points on the machine are to be sed.
Fig. 4: Transport ring bending machine
For transport, all rollers m st be fixed and all covers m st be attached to the
machine frame.
The machine m st not be rocked d ring transport by crane.
WARNING: ANGER OF TIPPING
The device may be lifted nsec red by a maxim m of 2cm.
Employees m st be o tside the danger zone, the reach of loads.
Warn employees and, if necessary, advise employees of the hazard.
ANGER!
anger to life due to falling of the load!
Falling loads can ca se serio s inj ry or even death.
- Never step nder s spended loads.
- Fix loads caref lly.
- When leaving the workplace, lower the load.

Transport, Packaging, Storage
PRM F | Version 1.07 | EN 13
5.2 ackaging
All packaging materials and packaging aids sed in the machine are recycla-
ble and m st always be recycled.
Cardboard packaging components m st be shredded for collection of waste
paper.
The foils are made of polyethylene (PE) and the pholstery parts made of poly-
styrene (PS). These s bstances m st be handed over to a recycling center or
to the responsible disposal company.
5.3 Storage
Store the machine thoro ghly cleaned in a dry, clean, d st- and frost-free env-
ironment. It m st not be placed in a room with strong oxidizing chemicals.
If the machine m st be stored in a damp room, all electrical components m st
be protected by moist re-absorbing agents. Also, all bare metal parts m st be
greased against r sting.
