1 Notes on safety
The RA 21/RA 21 Special Pipe Cutting and
Bevelling Machine (referred to as a pipe cutter
in the following) 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. It may also damage the machine or
other equipment.
Therefore:
º Always ensure that the machine is in good

Always consult Georg Fischer after-sales
service personnel before using other
materials.
º Only use the pipe cutter for cutting and
bevelling operations as described in
chapter 6.
º Only use original Georg Fischer spare parts
and auxiliaries.
º Inspect the pipe cutter every day for visible
signs of damage or defects. Any damage or
defects must be repaired immediately.
Work on the electrical installations may only
be performed by a qualified electrician.
º Do not use the pipe cutter unless all safety
devises
- restart inhibitor
- overload protection
- saw blade guard
are working properly and the fixtures on the
vise and baseplate are fitted securely.

Working with safety in mind
"Make your contribution to safety at the workplace."
Report any unusual behaviour on the part of the
machine to the person in charge immediately.
Always work with safety in mind.
º Wear safety goggles during
cutting and bevelling operations.
º Switch the RA 21 (S) off after
completing each stage of work and
allow the machine to run a stop.
º Disconnect from the mains before
cleaning the pipe cutter.
The cutter and saw blade may cause
injury.
Therefore:
º Keep your hands away from the
tools during cutting and bevelling
operations.
Keep the pipe cutter dry, do not use
in the rain.
Do not use the pipe cutter in areas
subject to explosion hazards.
Disposal
Please make sure that material chips and used
gear oil are disposed of properly.
Further safety rules
Comply with the regulations, standards and
guidelines that apply in your country.

2 Description of the
pipe cutter
The pipe cutter is a robust, user-friendly,
service-friendly and safety-oriented design.
Vise and saw
All mechanically stressed parts are metal.
The rounded, smooth edges help to avoid
accidents.
The saw blade and jaws are close togethers
which reduces vibrations during cutting.
Motor and power cable
The motor can be easily removed. The motor
housing and switches are made from lightweight,
impact-resistant plastic.
Integrated into the power cable is a slipring
contact which prevents the cable from twisting
during cutting.

3 Features and scope of
application of the pipe
cutter
The pipe cutter
º is a fully configured working machine suitable
for workshop and building site operation;
º is part of the combined KM 2 and GTM 2
pipe cutting and threading machines;
º works using the safety-enhancing principle:
stationary pipe, rotating tool.
The pipe cutter is suitable for
º cutting and
º bevelling
pipes.
The cut pipes are free from burr, so no
deburring (in- or outside) is required.
This reduces the risk of corrosion.
Scope of application RA 21 RA 21
Special
º pipe Ø 1/4" to 2"
or 10 mm to 63 mm X X
º up to 5.5 mm wall
thickness
Chrome and stainless
steel pipes up to 1.5 mm X
wall thickness
Solid material
Ø 6 mm to 16 mm X
