cleaning

Periodically, remove the cover from the plasma marking control box and, wearing proper eye protection, blow accumulated
dust and dirt from the air passages and the interior components using clean low-pressure air. It is imperative that the air
passages to the interior of the unit be kept free of dirt accumulation to ensure adequate circulation of cooling air.
The length of time between cleaning will depend on the location of the unit and the amount of dust in the atmosphere.
After cleaning with low-pressure air, check for and tighten any loose hardware, including all electrical connections. Check
for frayed and/or cracked insulation on all power cables and replace if necessary.
