5. Carefully lay the nozzle back into the groove of the swing arm. Put the nozzle into the same
position as before.
6. Carefully tighten the screw

to clamp the nozzle.
NOTICE Too much torque will squeeze or damage the nozzle.
6.3.2 Attaching the Silicone Hose
After exchanging the carbon nozzle, reattach the silicone hose.
Info
It is very important that the silicone hose does not cause strain which impacts the sprung
loaded return position of the nozzle. The silicone hose should be pushed onto the nozzle to
such an extent that it is not going to become loose after repeated swing movements of the
swing arm.
Procedure
1. Use appropriate tweezers to clamp the flexible silicone hose in place. Slide the flexible sili-
cone hose onto the nozzle.
2. Alternatively, slide the flexible silicone hose onto the nozzle. Use appropriate tweezers to
clamp the flexible silicone hose in place.
6.3.3 Checking the Position of the Carbon Nozzle
Exchanging the nozzle and adjusting the nozzle clamping alters the lateral (sideways) position of
the carbon nozzle.
It is important that the nozzle does not hit the side of the specimen, even if the specimen is raised
throughout an extended experiment.
Procedure
1. Check the coarse elbow adjustment.
The nozzle should be close to the specimen.
This will not need regular adjustment. The elbow is adjusted at installation for a typical
specimen.
2. Check that the nozzle height is appropriate.
This will not need regular adjustment. Adjust the height after exchanging the carbon noz-
zle.
Refer to
Adjusting the Height of the Carbon Nozzle [
}
25] .
3. Check the lateral position of the carbon nozzle and the distance of the nozzle to the speci-
men.
This will not need regular adjustment. Adjust the lateral position and the distance to the
specimen after exchanging the carbon nozzle or when working with different shaped or
positioned specimens.
Refer to
Adjusting the Lateral Position of the Carbon Nozzle [
}
26] .
4. Check that the silicone hose is well attached, but does not provide strain throughout the
swing arm movement.
Refer to
Attaching the Silicone Hose [
}
24] .
5. Check and finely adjust the stop position, and clamp the locking screw.
This should always be checked.
