LASER ENGRAVER SAFETY
NEVER over ride any of the safety switches on the engraver or leave the engraver
unattended while it is in operation.
NEVER operate the engraver with the lid up or any of the doors open. These should be
locked at all times.
KEYS: - The laser engraver has locks with keys provided with the machine.
All doors with locks must be locked and keys removed.
Only one key should be kept with the Operator at any time.
Please put all other keys away safely.
NEVER look directly into the laser beam.
RECOMMENDED:
It is recommended that the user wears eye protection, especially when aligning the beam.
HPC laser can supply suitable glasses. Alternatively 10.6 micron protective eye wear can
be purchased elsewhere. This protection will not impair viewing and can easily be
combined with safety glasses.
ELECTRICAL SAFETY
DO NOT open the centre and lower right panels of the machine when switched on as there
is mains voltage present.
DO NOT make or break electrical connections to the engraving system when the unit is
turned on.
FIRE SAFETY
Laser engravers represent a potential fire risk.
Most engraving materials are inherently combustible, and while the objective of most
engraving and cutting operations is to vaporize material without burning, it is astonishingly
easy to ignite a flame. Usually this is a simple “flare” of burning gases, issuing from the
focused spot on the engraver, which follows the moving spot and which extinguishes itself
as soon as the laser beam is modulated off. Should the engraver actually be set on fire,
the fire must be extinguished by the operator at once after using the emergency stop
button, or the engraver will be seriously damaged or destroyed!
DO NOT operate the engraver in the presence of unnecessary combustible materials.
Remove the debris from under the work table regularly.

HPC LASER LTD –NEVER LEAVE YOUR MACHINE UNATTENDED WHEN WORKING
NEVER operate the machine without a fume filter system or a properly operating vent to
the outside! Most material will only produce an irritating smoke when engraved. Some
materials, including but not limited to paint, varnish, composition board and plastics
produce compounds that can be harmful if concentrated. A properly installed vent is the
only way to ensure that problems do not occur.
NEVER engrave or cut any material containing PVC or vinyl. When engraved, a
corrosive agent is produced that will destroy your machine.
Any non recommended materials being used on the unit should be assessed for
potential dangers:- e.g Health & Fire Risks.
NEVER operate your machine unattended. There is a significant risk of fire if the machine
is set improperly, or if the machine should experience a mechanical or electrical failure
while operating.
NEVER operate with any of the covers or enclosures removed, and never modify the
enclosure. The laser is invisible!

Section 1: Unpacking your engraver
Unpack the machine from the wooden crate using 14mm and 17mm spanner.
Wear protective gloves to avoid splinters.
Environmentally dispose of packaging safety.
Unload the machine and place on a level floor.
Remove DVD / software CD from the accessory pack and watch installation DVD fully.
Remove transit cable ties to all parts, including laser head, keys, and laser bed.
Unlock side doors using keys provided to allow laser tube removal.
Put keys into the on / off key switch.
Undo rear flap of engraver using keys, use “stay” to hold flap in upright position.
Open the left hand lower cabinet door, and remove the accessories.
Take the foam laser tube mounts and allen keys from the accessory pack, and use allen
key to unscrew the clamps which hold the laser tube.
Unpack laser tube from brown cardboard box, visually check tube for damage.
Check for damage prior to fitting.
Insert laser tube into holders with the metal end of the laser tube nearest to the mirror (to
the right of the machine)
Clamp in place (loosely) this allows the tube to be rotated to allow air bubble removal later
if required.
Connect rubber water pipe to each end of laser tube, insert laser tube with the metal end
approx 50mm from the mirror.
Tighten the tube clamps using allen key.
Push on the power connectors to the laser tube, black at the mirror end, red at the control
panel end, secure these in place with a blob of silicone (dow corning 732 multipurpose
sealant).

Section 2: Laser tube / pump
Unpack the water pump (if not using chiller) immerse in contained (min 35l of deionised
water), connect outlet from pump to water inlet pipe.
The return pipe goes back into the tank.
Remove air compressor from the box, connect the pipe which leads to the air inlet on the
rear of the engraver.
Connect all power leads into on 4-way extension.
Section 3: Fan Unit
Unpack the off centre fan unit, connect the horizontal inlet to the rear of the machine, and
vertical outlet to your exhaust. Plug in to extension lead.
Section 4: Installation of Software
Connect the USB lead to the computer, plug in the software dongle (looks like a small usb
stick) into the USB port, switch on the computer.
Insert software CD from the accessory pack.
Open CD drive on computer, click on English.
Double click on install
Double click on set-up
(welcome to use)
Click Set-up
(proceeding date)
Succeed in install)
Click “OK”
Close Box
The software will install on the desk top, with an icon stating “laser cut”.
Double click on this to open the software.
Section 5: Initial set up of engraver
Power on the extension lead, check the fan and air pump are working, check the water
flow through the laser tube, visually inspect to make sure there are no air bubbles, (if these
do not disappear release the clamps and rotate the tube gently to be in a position where
these are no longer visible) –re-tighten clamps on completion double check the engraver is
level.
Close the rear flap over the laser tube, lock and remove keys (put away for safe keeping)

On the rear of the machine, switch the on / off switch to “on”
If the red emergency button on the top of the machine is “depressed” turn clockwise to
release this.
(The machine MUST run for a minimum of 5 minutes to ensure the tube is at a
constant temperature –before each use).
Now turn the key switch to the “on” position, check the alignment (as per DVD) ensure the
Lid is down, and all side doors are closed and locked before firing the laser.
To check alignment:-
Tear four pieces (each 15cm) Cardboard and stick onto each lens (try your best to
not stick onto the lens, as picture 1). Manual test “laser”, laser will print one black
point on the paper. Do not hold the “laser” switch down, just enough to make a
black point appear. The position of black point should be in the middle of reflection
lens (as picture 2).
Follow the above instructions for lens 1 and 2

After adjusting lens 1 and lens 2, stick the adhesive paper onto the dolly, and then
move the dolly to the top of the bed, close reflection lens 3 and reflection lens 4,
manual test the laser and print one black point. Then move the dolly to the most
right hand side, manual test the laser and print one black point. The black dot needs
to be central in the cardboard, if not, adjust manual screw of lens 4, and then test,
until finally completely central.
YOUR MACHINE IS NOW READY TO USE
Note: if machine is re-sited, the above procedure
needs to be repeated
If your machine was installed by an HPC LASER ENGINEER please refer from this

Tips for getting better results from engraving:
A. Slow the speed down
B. Un-tick the bi-directional box
C. (Reduce any lines) by reducing scan gap

TROUBLESHOOTING
Problem: Engraver will not vector.
Solution:
Please verify that the print driver is set to “vector” or “combined”.
Verify that your artwork is correct for vectoring.
Scanned images will not vector.
Filled or solid images will not vector (outlines only).
If you are using CorelDraw verify that line width is .007 or less.
Problem: Engraving appears weak.
Solution:
All mirrors and lens need to be cleaned and inspected for damage,
please watch DVD for instructions.
Make sure that the lens is in correct focus.
Make sure the correct speed and power settings
for the type of material that you are engraving on.
Problem: No laser beam but the engraver appears to be running normally.
Solution:
Make sure focus is set properly
Make sure the power and speed settings are appropriate
Please refer to setting sheet provided with your machine
