Maintenance
Cooling Fan Filters
This air-cooled laser system will require periodic cleaning of the cooling fan lters. Since ambient air is used to cool
the laser cartridge, the air must be ltered before it enters the inside of the laser system. Dirt or dust
contamination may reduce the cooling fan’s ability to keep the laser cartridge, as well as the CPU and power supply,
from overheating. An overheated laser cartridge will lose laser power during engraving and will eventually shut
down completely.
To service the lters, rst turn OFF and unplug the laser system. To remove the lter(s), simply snap o the black
cover and remove the foam element. Wash the element in a soap and water solution, dry and re-install.
Note: The VLS6.60 has a total of three large lters: two located on the back and one lter located on the side
near the power switch.
CAUTION: Never operate the laser system with the cooling fan lters removed. This can
permanently damage the laser system. Damage to the laser system due to inadequate or
improper operating environment is not covered under the ULS Warranty.

Adjustments and Lubrication
Periodic adjustments are not normally required. The bearings in the motion system will self-adjust to take up any
clearances as they begin to wear. The belts are ber-reinforced and will not stretch under normal use so periodic
tension adjustment is not necessary. Optical alignment is not necessary because the laser and the #2 mirror are xed.
All bearings in the system are sealed and do not require lubrication. Do not lubricate the tracks that the bearings
ride in. The only lubrication that may be required is the screw threads for the table lifting mechanism. As time
passes, contaminants may adhere to the lubricant which can cause the engraving table to bind up or sound squeaky.
If this is the case, wipe o the contaminated grease with a soft cloth dampened with alcohol and apply fresh white
lithium grease to the screw threads. Never spray any degreasing solutions directly onto the threads. Run the table
up and down to work in the fresh grease. Repeat if necessary.
