Safety Precautions and Warnings

Evolution Series CNC Routers have a 110 v. power supply and use bits that spin at

28,000 rpm with cutting edges that are sharp and hazardous. The operator must

understand the potential hazards and is responsible to take appropriate safety

precautions before operating the Router.

•Only use extension cords rated for 20 amps plugged into a dedicated outlet.

•Inspect the machine before every use for maintenance issues: loose fasteners,

belts, etc.

•Do not operate the machine with dull or damaged router bits.

•Always unplug machine after each use and when cleaning the router or changing

router bits.

•Remove rings, bracelets, watches, necklaces before using the machine.

•Wear snug fitting clothing and/or roll up long sleeves to prevent snagging.

•Use appropriate personal protective equipment (PPE) when operating machine

including safety glasses and hearing protection.

•Keep hands, hair and clothing away from the moving parts of the machine.

•Do not operate the machine when under the influence of alcohol or prescription

medications.

•Make certain the workpiece is clamped securely in place before starting the

machine.

•Never leave the machine running unattended.

•Children must be supervised by adults when operating the machine.

•Do not operate the machine in the presence of flammable materials.

•Keep floors clean, dry, and free of debris to eliminate slip and/or trip hazards.

•Have a suitably rated fire extinguisher on hand when the machine is in operation.

Getting Started

Required Tools:

A pair of long nose pliers.

Diagonal Cutters or sharp knife to trim nylon ties.

Calipers or measuring tape to measure part placement.

Small standard screwdriver to connect electronics.

#2 Phillips screwdriver to mount home switches and stepper motors.

#3 Phillips screwdriver to build the main components.

220 grit sandpaper to remove laser marks on wood pieces (if desired).

LOCTITE 242™thread lock (fingernail polish can be used as a substitute).

Set of Metric Sockets and SAE Wrenches.

Set of Metric and SAE Allen Wrenches.

To Operate the EVOLUTION 4 CNC Router, you need will need:

Computer with control software for GRBL.

Materials for Projects.

1/4” Shaft Router bits.

Recommended for the electronic setup include:

Multimeter to correctly connect the Power Supply and to set the current for

the Stepper Motors (a great tool for general electronic trouble shooting).

Assembly Recommendations:

Use a large, flat, clean work surface for assembling your EVOLUTION 4.

All Screws (unless noted) should be installed snug, then rotated 1-2 ½

turns.

Light sanding may be required to remove any marks made by the laser.

Painting, or applying stain with a clear coat will provide extra protection to

the wood components

Try using strips of 1 inch blue painters’ tape behind the T-Slots to help hold

the Nuts in place during assembly.

Lock Nuts are never used to secure components that have T-Slots. They

are only used to mount components where the Nut is not held in a

T-Slot.

CAUTION This kit contains numerous small

components that pose a choking risk for small

children and pets. Keep kit pieces in a secure

location out of the reach or small children and pets.
