1 Notes on safety
The Pipe End Preparation Machine (in the following referred to as REB) is a
state-of-the-art machine. Using it for purposes other than those described in
this manual may cause injury to the user or to others. The machine or other
equipment may also be damaged.
Therefore:
Always ensure that the machine is in good working condition, and always
comply with these notes on safety.
Keep the complete documentation close by the machine.
All regulations generally valid for the prevention of accidents must be
observed.
1.1 Proper use
Use the REB only for preparing (beveling, squaring) of pipe ends made
from metallic materials (see chapter 3.2, p. 11).
The user will be the only person liable for damages caused by improper
use.
1.2 Safety regulations
Only use the dimensions and materials specified in this manual. Always
consult Orbitalum Tools after-sales service personnel before using other
materials.

Inspect the REB every day for visible signs of damage or defects.
Any damage or defect must be repaired immediately.
Work on the electrical equipment may only be performed by a qualified
electrician.
Only operate the REB (E) if both electrical protection devices, disable re-
start and overload protection, are in proper working order.
Disconnect the REB (E) from power supply before changing the tools or
carrying out maintenance and repair work and allow the machine to come
to a stop.
Operate the REB (D) only by the ON/OFF switch on the twist grip for speed
regulation.

1.3 Working with safety in mind
"Make your contribution to safety in the workplace."
Report any unusual behavior of the machine to the person in charge
immediately.
Always work with safety in mind.
Wear safety goggles and safety gloves when working with the REB.
Tie up long hair (snood-type cap); do not wear any wide clothing.
Attention: jewelry and ties can get caught by rotating parts.
Keep hands away from the tools during processing.
Switch off the REB after each working cycle and allow the machine to come
to a stop.
REB (E): Disconnect the REB from power supply before performing any
cleaning, maintenance or repair work and allow the machine to come to a
stop.
Do not carry the electric tool holding it at the cable and do not use it to pull
the plug out of the socket. Protect the cable against heat, oil and sharp
edges (chips).
REB (D): Shut down the compressed air supply before carrying out any
maintenance work or cleaning the REB and allow the machine to come to a
stop.
Do not use the REB in areas subject to explosion hazards.

6 Transport and assembly
6.1 Transport
REB (E):
Danger of death caused by electric shock and restart of the machine!
During transportation, the ON/OFF switch could be actuated inadvertently so
that the machine is started.
Cut off the power supply before carrying out the transportation or a
workplace change and allow the machine to come to a stop.
Only transport the REB by the carrying handles intended for this purpose.
REB (D):
Danger of injuries caused by restart of the machine!
During transportation, the compressed air outlet could be actuated inadvertently
so that the machine is started.
Cut off the compressed air input before carrying out the transportation or a
workplace change and allow the machine to come to a stop.
Only transport the REB by the carrying handles intended for this purpose.
The REB can be transported either by carrying or with a crane.
The REB can be operated in two ways:
A) Standing upright on the frame
The REB stands upright on the stand frame and the pipe to be prepared is
mounted to the mandrel. This is possible for short lengths of pipe and for
flanges.

Danger of injury!
Long length of pipe could cause the machine to overturn.
Support of the free end is required when processing long and heavy pipes.
B) Machine mounted to the pipe to be prepared
There are two options:
The REB is guided into the pipe with the mandrel and subsequently
fastened.
Or:
The mandrel is mounted to the pipe and the REB guided over the
mounted mandrel.
We recommend because of the high weight of the REB 20 (D), at first to mount
the mandrel as described above to the pipe and then to guide the REB over
the mounted mandrel.

7.1 Choose the wedges and the clamping chuck
The clamping range of the REB 6 and REB 14 given on each wedge, in mm
and inches, refers to the pipe inner diameter.

B: Pipe inner-Ø, with clamping chuck, in mm
C: Pipe inner-Ø, with clamping chuck, in inches
D: Pipe inner-Ø, without clamping chuck, in inches
The clamping range of the REB 20 is not given on the wedges, as they are
identical to the wedges of the REB 14. For transmission, see the table in
chapter 7.1.3, p. 17.
