Checking the coolants
Check the level of coolant each month, a label on the back of the machine indicates the minimum and maximum level for proper operation.
Remember that the coolant should be changed at least once a year, if possible before a lengthy machine downtime period.
Checking the filters
Check the status of the filters in the welding chamber and front compartment each month. Please refer to the section "Cleaning the filters".
Checking the resin filters
The integrated cooling system has two resin filters to soften the liquid. These filters should be replaced once every 12 months.
Checking the protective glass slide
Check the AR glass at least every three months, if it is damaged or very dirty with metal, replace it. Dirty or damaged glass can decrease the
energy yield.
This special anti-reflective glass is attached to the optical path outlet by means of an aluminum ring; this ring is held in place by two knurled
brass latches. If necessary, clean the glass using delicate paper without degreasers or other solutions.
