5.10 Changing the engraving needle
To change the engraving needle, proceed as follows: Release the securing
arrangement on the engraving
head and take out the
engraving spindle.
The connection cable does not
need to be detached. Now
rotate the depth adjuster away from the engraving spindle.
Caution: The engraving needle and the spindle may have
become hot due to operation.
Next, you must release the clamping jaws by using
the rotary knob at the end of the spindle. To do this,
push the knob in and turn it to
the left.
The jaws will now be open and
you can remove the
engraving needle.
Caution: Only release the clamping jaws just enough to allow the engraving
needle to be removed. The clamping jaws should only be opened completely for
cleaning purposes.
In order to ensure the correct length of the engraving needle, only use
engraving needles supplied exclusively by EK-TEAM with the identification ring.
We cannot undertake any guarantee for script quality or damage to the units if
other makes are used.
Caution: The tips of the engraving needles are highly sensitive and must be
treated very carefully. Avoid damaging the tips. If they are
damaged, the quality of the lettering will be severely impaired.
Slide the engraving needle into the clamping jaws as far as the
identification ring, and then tighten it up again.
Now rotate the depth adjuster onto the engraving spindle again,
until the tip of the engraving needle is still not quite projecting
(finger or material test).
Now put the engraving spindle back into the engraving head and tighten the clamping
block again with the quick-action clamping device.
For the zero setting of the engraving needle, now actuate the
Norm
switch and
proceed as described under 5.4.
