Gases and fumes generated by laser
machines are hazardous to your health. It
is your responsibility to install a dedicated
and rated fume extractor if toxic gases or
fumes are produced during laser cutting
operations.
Dust and embers from laser machines pres-
ent a fire hazard. DO NOT direct exhaust
ports anywhere combustible materials exist,
or combine laser extraction fan with wood-
working dust collection systems.

Installing Air Pump
The air pump is designed to blow air directly on
the laser focal point. Place the air pump away
from areas where dust can be drawn in through
the inlet port.
Note: A barbed fitting on the inlet port can be
fitted with a hose to draw air from an alternate
source, if required.
The pump has cooling fins to release heat during
operation and should NEVER be located inside of
an unventilated compartment, or any area where
temperature will increase from pump operation.
To install air pump:
1. Thread barbed fitting into air pump outlet port
and tighten (see
Figure 21).
2. Install air pump tubing onto outlet port barbed
fitting and connect to auxiliary systems AIR
IN fitting (see
Figure 18 on Page 24).
3. Place air pump, electrical cord, and hoses
in a location that prevents tripping hazards,
hose kinks, and abrasive damage.
Note:
The air pump generates vibrations
and should be secured to prevent pump from
"walking" during operation.
4. Connect air pump to power supply.
Note:
Air pump can be connected to auxiliary
power connection on rear of machine.
Installing
Extraction Fan
The extraction fan vents debris and fumes cre-
ated during laser operations using a centrifugal-
style fan. The extraction fan should be mounted
in a fixed location that reduces vibration, and the
inlet and outlet ducting should be secured at each
end to prevent separation. Extending ducting over
six feet, or adding multiple elbow connections is
NOT recommended due to reduced extraction
efficiency.
The extraction fan does not remove residual
odors from the machine when not in use. If mate-
rials have an unpleasant odor while being cut,
consider re-locating the machine to an area with
greater ambient ventilation.
If mandated by local fire codes, a spark arrester
may have to be incorporated into the extraction
system. One example of this is when the outlet
duct is connected to a vented container partially
filled with water. Inside the vented container, one
or more baffles are used to direct smoke and
embers toward the water, which will then naturally
rise up and outward from a vent on top of the
container.
IMPORTANT: The machine and extraction fan
are only to be used for laser cutting operations.
DO NOT use machine as a downdraft table for
sanding or other operations.
