PRELIMINARY CHECKS
1 - Place the head on the
maintenance stand.
2 - Make sure that the jet is stable
by validating the "Check jet
stability?" function.
3 - Validate the "Adjust the jet?"
function and start up the jet.
4 - Check that the recuperation
operates correctly.
SETTING THE JET IN THE
GUTTER
The operation includes three
related settings:
• cannon rotation,
• upper cam rotation,
• lower cam rotation.
In general, this is performed
gradually, stopping the jet from
time to time to clean the electrodes
if necessary.
5 - Remove the wire protection
plate from the resonator wires and
disconnect them.
6 - Unfasten the cannon-holder
screws (see Figure 1).
