YORAHOME CNC LASER ENGRAVING MACHINE 6550-PRO
USER MANUAL
Version 1.0 • June, 2022
Purpose
This Manual is intended for assembly of the YoraHome 6550-Pro Laser Engraving
Machine.
Before beginning assembly, we recommend conducting an inventory using the
Packing List to ensure all components are present.
NOTE - there may be extra hardware included; this is normal, in case items get
dropped or lost.
Please read these instructions carefully before assembling your machine to
prevent possible damage to your machine.
Safety1/3
➔Read and understand the entire user manual before attempting assembly or operation
➔Do not use the laser engraver other than its intended use. If used for other purposes,
YoraHome disclaims any real or implied warranty and holds itself harmless from any injury
that may result from that use.
➔Always wear approved safety glasses while using the laser engraving machine. Everyday
eyeglasses will NOT protect your eyes from the laser
➔It is not recommended to wear loose clothing around moving equipment. Confine long hair.
➔Do not operate the laser engraver while tired or under the influence of drugs, alcohol or any
medication.
➔Make all machine adjustments or maintenance with laser engraving machine unplugged from
the power source.
➔Give your work undivided attention. Looking around, carrying on a conversation and
“horseplay” are careless acts that can result in serious injury.
Safety2/3
➔Never leave the laser engraving machine running unattended. Turn the power off and do not
leave the machine until it comes to a complete stop.
➔Keep a fire extinguisher nearby since use of the laser may lead to an unexpected fire.
➔Remove loose items and unnecessary work pieces from the area before starting laser engraver.
➔The laser engraver should be set up in a fire-resistant working area with good ventilation.
➔Keep children away from your laser engraver. Minors of any age should not use this laser without
direct adult supervision and proper eye protection
➔Do not place your hands or any other objects you do not wish to engrave/burn/cut in the path of
the laser beam. Serious physical harm is possible if used improperly.
➔Do not touch the heat sink when the laser engraver is in operation, or immediately after use, it
may cause burns.
➔Never cut vinyl or PVC. When engraved, a corrosive agent is produced that will destroy the
machine. Never use unknown materials.
Safety3/3
➔Make sure the cutting area under the laser is metal or non-flammable.
➔Ensure that the room or area you are operating the laser in is sufficiently labeled to prevent
someone from unknowingly walking into an active work area.
➔Never use the laser except for the purpose intended.
➔When engraving mirror, stainless steel and other reflective materials, please paint the surface
black to prevent damage to the laser head from reflective light.
➔The machine should be placed securely on a flat surface to avoid dropping or being hit.
➔Be within reach of the Emergency Stop or pause button when the machine is in operation. In
the event of an emergency, or if there are any conditions that may result in injury to yourself or
others, the 6550-Pro is equipped with an Emergency Stop button on top of the Controller.
When pressed, this button will latch in the Stop position. To reset, twist the red knob
clockwise.
