Silica dust

Cutting concrete, stone and pavers releases crystalline silica dust, which can cause serious, permanent lung disease over time. Always control it:

• Keep the surface wet while cutting, or use a dust-collecting vacuum.
• Wear a properly fitted respirator rated for silica (N95 or better) whenever dust is present.
• If you have employees, OSHA’s respirable crystalline silica standard applies — you may need to measure exposure and provide respirators and training.

Eyes & hearing

• Wear impact-rated safety glasses — engraving throws chips and slurry.
• Wear hearing protection during extended cutting.

The router & moving gantry

• The bit is sharp and spins at high speed — keep hands, cords and clothing clear while it runs.
• The gantry moves on its own under machine control. Keep fingers out of its path and never reach into the work area during a job.
• Unplug the machine before changing bits or clearing a jam.

Electricity & water

• Plug into a properly grounded outlet. On job sites, follow OSHA’s ground-fault protection rules for 120V power.
• Fine-detail bits run wet — keep water away from the controller, the laptop and all electrical connections, and never let the machine sit in standing water.
• If an outlet or breaker trips, stop and contact support before continuing. Never bypass a protective device.

Lifting & transport

• The machine packs into a rolling case weighing about 114 lb. Use the wheels, get a hand loading it into a vehicle, and lift with your legs.

Keep bystanders clear

• Set up a work zone and keep people, pets and traffic away from the machine, the dust and the cords while it runs.

Before every job

• Confirm the surface is cured and solid.
• Set up dust control and put on eye, hearing and breathing protection.
• Check the power source and cords.
• Clear the work area of bystanders.
