Grounding Methods
This machine must be grounded while in use to protect the operator from electric shock.
In all cases, make certain that the receptacle in question is properly grounded. If you are not
sure, have a qualified electrician check the receptacle.
Grounding Methods Provided by CSA Group. (A) Receptacle with nominal rating less than 150 volts. (B) 150
volt receptacle without grounding pin fitted with adapter.
1. All grounded, cord-connected machines:
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the
risk of electric shock. This machine is equipped with an electric cord having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into a matching outlet that is properly installed and grounded in accordance with
all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet, have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding conductor can result in risk of electric shock. The conductor with
insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding conductor. If
repair or replacement of the electric cord or plug is necessary, do not connect the equipment-grounding conductor to a live
terminal.
Check with a qualified electrician or service personnel if the grounding instructions are not completely understood, or if in
doubt as to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding type plugs and matching 3-conductor receptacles that accept
the machine’s plug, as shown in Fig. A. Repair or replace damaged or worn cord immediately.
2. Grounded, cord-connected machines intended for use on a supply circuit having a nominal rating less than 150 volts:
If the machine is intended for use on a circuit that has an outlet that looks like the one illustrated in Fig. A, the machine will
have a grounding plug that looks like the plug illustrated in Fig. A. A temporary adapter, which looks like the adapter
illustrated in Fig. B, may be used to connect this plug to a matching 2-conductor receptacle as shown in Fig. B if a properly
grounded outlet is not available. The temporary adapter should be used only until a properly grounded outlet can be installed
by a qualified electrician. The green-colored rigid ear, lug, and the like, extending from the adapter is used, it must be held in
a place with a metal screw. NOTE: In Canada, the use of a temporary adapter is not permitted by the Canadian Electric
Code.

PL1220 Precision Laser \ Electrical Saftey \
Extension Cords
Use proper extension cords. Make sure your extension cord is in good condition and is a 3-wire extension cord
which has a 3-prong grounding type plug and matching receptacle which will accept the machine’s plug. When using an
extension cord, be sure to use one heavy enough to carry the current of the machine. An undersized cord will cause a drop
in line voltage, resulting in loss of power and overheating. Fig. D.1 or D.2, shows the correct gauge to use depending on the
cord length. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Leveling the Machine
You will need 2 persons and a level to complete this setup section.
1. Make sure you are setting the machine up on a level surface
2. If you chose to purchase the optional base, start by leveling the base to the floor by installing and adjusting the wheels.
3. Otherwise, place the Z-axis base on the desired surface or floor and proceed to level the base by adjusting the pads on
the bottom of the base.
4. With two persons, place the pl1220 centered atop the Z-axis base and level the pl1220 to the z axis base.
5. Reference the connections guide above to plug in the power cords, connection cords, and earth ground.
The Pl1220 does not need to be sitting on the Z-axis base to operate. It has been designed
where if the z-axis base is not connected, everything will still work other than the auto-focus
control. Important: If the z-axis base is not connected, the focal length will need to be set manually by twisting the cap and
setting the proper focal spacing. The PL1220 is also designed to be used with an "open bottom". An example of this is when
the operator would want to engrave onto the surface of a table. The operator will move the PL1220 to the tabletop, set the
focal spacing manually and then proceed to operate the laser.
Remove all Zip Ties
After the machine has been moved and leveled to where it will be used, remove the zip ties on the belts and install the
exhaust adapter. You will need tools to remove the zip ties, and an Alan key to install the adapter.
Be careful not to cut or nick the belts when removing zip ties.
1. Remove all zip ties [A] from the Belts and Laser Head Assembly. There is one on each belt to prevent movement in
transit, and one on the laser head assembly.
2. Install the Fume Extraction Adapter [C] on the rear of the machine with the included Alan keys.

8. Connect the low voltage (-) terminal (anode) to the power supply according to the wiring diagram in this manual. Use the
wire with the alligator clip.
9. Re-install the top mounts (E) and fasten the laser tube in place.
10. Slightly tighten the tube top lock screw to give slight pressure to the laser tube.
11. Make measurements and adjust the tube height adjustment dials (D) until the laser tube is firing perfectly straight.
CAUTION: Ensure the Tube Height Lock Screws (C) are loose. NOTICE! If using a level, make sure that the laser
machine is on a level surface. Note that it is crucial that the laser tube is parallel to the chassis of the machine. The first
step of mirror alignment is to make certain that the tube is parallel to the chassis of the machine such that the mirrors
can then be aligned to that plane.
12. Tighten the Tube Height Lock Screws.
13. Do not worry about testing the laser for alignment at this point as we need to install all other systems prior.
