5 Maintenance
5-25
4 Place a gap gauge between the electrode holders so that the left side of the
gauge would contact the electrode holder.
5 Insert a new electrode (or reconditioned one) into the electrode holder so that
the tip would contact the gap gauge. Then, tighten the fastening screw.
How to Adjust Control Gap
6 Take off the gap gauge.
7 Mount the front panel of the excitation unit.
8 Turn ON the SOURCE switch on the switch panel.
● If the gap gauge is used upside down, control gap becomes too
large, generating abnormal voltage. It may cause dielectric
breakdown on the igniter or damage the igniter coil.
Be sure to use the gap gauge in the correct direction. (Control gap
should be 7mm)
● Do not make discharge with the gap gauge on.
