WARNING!
WARNING! Never perform any setup, maintenance or adjustments with the machine connected to the power
source!
WARNING! If you have any doubt about the described procedure, seek professional assistance. Do not attempt
any procedure that you feel is unsafe, or that you do not have the physical capability of achieving.
WARNING! When removing banding, extreme caution must be used as the banding will spring when cut.
CAUTION! The machine is heavy. Ensure that you have enough people to do the job safely.
NOTE: There may be sawdust in or around your new machine as a result of thorough testing prior to shipment.

3.1 Service Schedule
Many laser engraving/cutting machines are sold under a service contract - a
document outlining servicing tasks that must be completed and verified on a
regular basis. These machines are not under a binding contract but it is in the
owner's best interest to follow this schedule as closely as possible. The quality and
speed of cut and, more importantly, length of machine life will be maximized if this
scheduled maintenance is followed. Most importantly, the risk of personnel injury
and damage to the machine is greatly minimized under strict compliance with this
schedule.

X,Y,Z Guide Rails
Cleaning - Cleaning metal parts (guide rails) is often best done with isopropyl
alcohol, a lubricant, or mineral oil. Special care must be taken not to scratch or
damage sensitive coatings applied to the optics - a microfiber cloth, cotton swab,
and glass cleaning solution is adequate.
Cleaning the exhaust pathway and debris around the vector grid (work surface) is
critical to prevent fire. Prior to every use, empty the collection bin and vacuum out
any debris accumulated around or on the work area. On a weekly basis, take out the
honeycomb table and clean it with compressed air and a wire brush.
Lubrication - The only lubrication needed is directly applied to the linear rails. The
number one lubrication mistake is not whether to use grease or oil but rather not
lubricating the machine often enough (or not lubricating it at all). A general purpose
grease is adequate and recommended. Oil will also work if the grease already on the
linear rails is removed before applying the oil. Apply the lubricant and cycle the drive
system limits to distribute the lubricant to the bearings.
Replacement Parts - Many of the replacement parts can be purchased from several
different sources. There are no components in the machine that are proprietary to
Laguna Tools - making it easier for the service technician to find replacement parts
like belts, motors, mirrors, mounts, and electronics.
If Focal Lens is dirty - Check the air supply, air valves, and all air connections. Many
times the focal lens is contaminated by the evolution of gasses in the process. The
air supply is designed to prevent those gasses from rising to and contaminating the
focal lens.
If Mirrors are dirty - Check the exhaust system connections and CFM requirement of
the machine. Often the mirrors are contaminated by fumes or particulate matter in
circulation around the work area. It is the exhaust systems primary function to
direct these contaminants away from sensitive components like the mirrors. If the
process is generating a high volume of smoke/fumes - ensure that the Material
Parameters are correct (not overpowered), and that the exhaust system is properly
suited to capture the high volume.
