M90 Fusion Splicer 7-30 Operating Instructions
Troubleshooting and Care/Maintenance Issue 02/97
Mechanical
cleaning
If the electrodes still do not function correctly after burn-off, clean them mechanically.
When cleaning the electrodes, use only the swab holder and a piece of emery paper
provided in the tool bag.
- Place a piece of emery paper (with the
rough
side to the inside) in the notch in the
swab holder.
- Dismantle the electrodes.
- Position the swab holder on the electrode.
- Carefully turn the swab holder several times (see next figure).
- Do not touch the tips of the electrodes with your fingers after cleaning.
- Clean the second electrode in the same way.
Cleaning the Electrodes
Ultrasonic clean-
ing
You can also clean the electrodes in an ultrasonic bath. We recommend you use alco-
hol for the solvent.
Danger
Never spray solvents or other cleaning agents into the area of the electrodes or lenses.
The electric arc can ignite the gas mixture.
If the cleaning proves unsuccessful or the electrodes are too heavily worn, they will
need to be exchanged. Use only original electrodes.
Caution
Reinstall and tighten the electrode.
Performing fusion without electrodes in place will damage the splicer!
