1. Operating instructions
Please read these operating instructions
carefully prior to using the tool. Im-
proper use may cause the tool to work
incorrectly. All information and instruc-
tions contained in this document apply
to the specied tool and may only be
used for the purpose of operating this
particular tool.
Prior to adjusting, operating or servi-
cing this tool, the individuals concerned
must read and observe these operating
instructions. In certain cases, the seller

2. General description
The RL50-2 is a high-speed, hydro-
pneumatic riveting tool designed to pre-
cisely install blind rivet nuts and blind
rivet studs. The spin action delivered by
the tool’s hydro-pneumatic system ena-
bles rivets to be pre-assembled on the
mandrel and then detached. The pull-to-
force and pull-to-stroke settings can be
adjusted individually or in combination
to deliver the best-possible installation
results regardless of the eld of appli-
cation.
This hydro-pneumatic tool is designed
for the installation of M3 to M10 (M12
Al) blind rivet nuts and M4 to M8 blind
rivet studs.
3. Scope of use
1Use pull-to-stroke to adjust
2Use pull-to-stroke, pull-to-force or combination of
both to adjust
Always read these operating instructi-
ons prior to using this tool and observe
the applicable safety regulations.
4. Occupational health and safety

drels/internal threaded mandrels and
nosepieces must be chosen depending
on the blind rivet nut/blind rivet stud
diameters concerned.

equipment should be used/worn at all
times.
— If not in use, the tool must always be
disconnected from the compressed air
supply.

— Do not use the tool without a tted
end cap (10).
— The compressed air supply must be
lubricated or oil lled manually to
prevent any issues arising with the
motor
NOTE
The manufacturer shall not be liable for
any damage incurred due to improper
repair work or the use of non-original
spare parts.
The warranty shall be rendered invalid
if any repair work results in the riveting
tool or the seals becoming damaged.

8. Commissioning
Perform a visual check of the riveting
tool prior to each use:
- for visual damage
- for oil leaks
Prior to using the tool, perform a
functional test (20 dummy installations
without rivets).

9. Tool operation
— Perform a functional test after inspec-
ting the tool or prior to using it for the
rst time (commissioning)
— Connect the tool to the air supply (6 to
7 bar)
— To prevent the tool from being dama-
ged due to an overly high supply of air
pressure, the integrated safety valve
will trigger and release air. If this occurs,
adjust the air pressure to the correct
value.
— Check that the quick connectors have
been correctly tted – no hissing (air
discharge) should be audible.
— Push the blind rivet nut onto the threa-
ded mandrel. This will start to rotate
automatically until the rivet is fully
situated on the mandrel.
— Be sure to hold the tool perfectly per-
pendicular (90°) to the surface of the
work piece.
— Press and hold the trigger (7): the rive-
ting tool will perform a pulling motion.
After nishing the riveting process, the
mechanism will automatically return to
its initial position and the mandrel will
spin off the blind rivet nut.
— If the blind rivet nut needs to be remo-
ved from the mandrel for whatever rea-
son, press the trigger (8) to activate the
spin off action: the threaded mandrel
will then spin off the blind rivet nut.

— Each snap index on the stroke adjuster
(11) equates to a change of stroke of
roughly 0.08 mm.
— Each marking on the stroke adjuster is
equivalent to roughly 1 mm.
—
9.3 Setting the pull-to-force
— To adjust the pull-to-force, the stroke
adjuster (11) must be set to its maxi-
mum position (rotate anti-clockwise)
— First, set the pull-to-force to its lowest
value by turning the force adjustment
screw (9) anti-clockwise until it rea-
ches its end position
— Then screw on the blind rivet nut/blind
rivet stud by hand
— Perform a rivet installation test. If
correctly installed, the nut should not
deform. The blind rivet nut/blind rivet
stud should spin off from the mandrel/
internal mandrel automatically.
9.1 Set-up options: setting the pull-to-
stroke/pull-to-force
— The tool’s pull-to-stroke and pull-to-
force can be set individually or in
combination.
— If you want to use the riveting tool for
different clamping thicknesses without
having to adjust the tool settings, the
recommended approach would be to use
the “Setting the pull-to-force” option.
— The “Setting the pull-to-stroke" option is
ideal for use on smaller blind rivet nut
dimensions (M3, M4, M5) or if the rivets
to be used are made of soft materials.
— The pull-to-stroke setting is also re-
commended if working with a single
clamping thickness only.
— To set the pull-to-stroke and pull-to-
force in combination, please follow the
steps outlined below.
9.2 Setting the pull-to-stroke
— To activate the pull-to-stroke mecha-
nism, the force adjustment screw (9)
must rst be set to its maximum value.
To do this, rotate the force adjustment
screw (9) clockwise as far as it will go
(max. pulling force).
— Remove the end cap (10).
— Adjust the stroke by turning the stroke
adjuster (11): to reduce the stroke,
rotate clockwise; to increase the stroke,
rotate anti-clockwise.

— Turn the force adjustment screw (9)
clockwise to increase the pull-to-
force.
— After adjusting the pull-to-force, press
the trigger at least 5 times before
installing the next rivet.
— Check the outcome of the rivet ins-
tallation that results from the new
setting and repeat the entire process
if necessary while gradually increa-
sing the pull-to-force.
— Adjust to the required pull-to-force
by turning the adjustment screw
clockwise (+) or anti-clockwise (-) and
perform a rivet installation test each
time until the ideal setting is found
and the blind rivet nuts/studs deform
as desired.
Pull-to-stroke and pull-to-force settings
in combination
A combination of both functions is espe-
cially advantageous whenever a high
pull-to-force should be achieved whilst
also protecting the threaded mandrel as
well as the internal thread of the rivet
nut.
It is also the recommended choice in the
case of small-diameter blind rivet nuts/
blind rivet studs or blind rivet nuts/blind
rivet studs made from soft materials.
— First, adjust the pull-to-stroke setting
as desired by following the steps outli-
ned under “Setting the pull-to-stroke”.
— Then adjust the pull-to-force by
turning the force adjustment screw (9)
as needed (clockwise to increase the
pull-to-force; anti-clockwise for less
pull-to-force) until you achieve the
ideal pull-to-force setting for the rivet
installations you wish to perform.
10. Intended use
To ensure compliance with all of the
relevant safety measures and that the
riveting tool will work correctly, the fol-
lowing requirements must be fullled:
— The tool must only be used in compli-
ance with the dened technical spe-
cications and all specications con-
cerning the use, assembly, connection
of the tool as well as the permissible
environmental and working conditi-
ons observed. These specications
and conditions, along with all infor-
mation concerning use of the tool, are
stipulated in the documents as well as
the operating and maintenance ins-
