4.2 FUNCTION
Stapler JK20A670 has both single shot and continu-
ous ring without safety yoke.
Never re staples into the air!
1. Single shot ring:
Press the single re button (Fig. 1/2) on the left
side above the trigger and a single shot will be
red when the trigger is activated.
2. Continuous ring:
Release the single re button (1/2) on the left
hand side and continuous ring will occur for as
long as the trigger (1/3) is activated.
3. Speed of continuous ring:
The ring speed is regulated by the speed adjust-
ment knob (1/6) on the right side. Turning counter
clockwise will increase the speed (max. 28 shots/
sec) at 7 bars (100 psi); turning clockwise reduces
the speed.

5INITIAL OPERATION
5.1 INSTALLATION
The stapler is delivered without the compressed air
connection nipple assembled. Assemble the nipple as
following:
1. Take the stapler out of the box. Check that the
nipple is the correct brand and ts your air sys-
tem. Put sealing compound on the thread.
(Fig. 2/1).
2. Assemble the nipple. Tightening torque 7.5 Nm.
Lay the compressed air hose so that
there is no risk of tripping over it.
5.2 AIR CONNECTION / LUBRICATION
Properly prepared compressed air is essen-
tial for trouble free operation of the stapler.
This can only be ensured by a reliably functioning
maintenance unit, consisting of water separator, pres-
sure reducing valve with pressure gauge. The internal
diameter of the pipe should be at least 10 mm (3/8“).
Never exceed the maximum permitted air
pressure of 7 bar (100 psi). The maximum
supply pressure is 7 bar (100 psi).
A low air pressure will give low maintenance costs!
The stapler and the hose must have a coupling which
automatically bleeds all air pressure from the stapler
when it is disconnected.
The stapler needs a small amount of lubricating oil in
the nipple each day or approx. 10 drops once a week
to ensure safe functioning and endurance. For high
frequency stapling we recommend oil mist lubricator.
Please contact our agent for advice.
733007 Lubrication oil 0.2 dl. (Fig.3/1)
Sliding parts are greased, with Dow Corning grease
MS 4 Silicon Compound, at the factory. We recom-
mend use of this grease on moving parts if they have
been cleaned or replaced.

6OPERATING INSTUCTIONS
6.1 LOADING THE MAGAZINE
– Connect the tool to the compressed air line before
loading staples. The max. allowed air pressure is 7
bar.
–Always use Josef Kihlberg original staples
JK670 with leg length 06 (1/4“ ) to 12 mm (1/2“).
The correct type of staple is marked on the right
side of the magazine. Ensure you use the right
length of staples for your application.
1. Pull the magazine lid all the way out (Fig. 4/1)
2. Place the staple strip (4/2) into the staple rail from
the left hand side.
3. Place the staple strip into the magazine and push
the lid (4/3) forward again until it clicks in.
Be sure that the tool is not pointing at
yourself or anyone else when connec-
ting it to the compressed air line.
Warning: before stapling, ensure that
your hand or any other part of your
body is not underneath the nozzle.
6.2 OPERATING THE STAPLER
Adjust the air pressure to the lowest one that will drive
the staples to the desired depth. Start at approx. 5.0
bar (72 psi) and raise this by 0.5 bar (7 psi) increase
until the correct operating pressure for the job in hand
is found. Never exceed 7 bar (100 psi).
A low air pressure will give low maintenance costs!
– Place the tool rmly on the work surface. Never
drive staples in extremely hard or brittle material.
– Push the trigger as described in chapter 4.2
– Move the toll sideways until you have nished the
stapling and then release the trigger.
Always place yourself in a rmly balan-
ced position when using or handling the
tool. Do not drive staples at too steep
an angle or too close to the edge of the
work: the fastener might y free and hurt
someone.
