FEATURES

1. This machine may be used for surface cutting, drilling, milling, and tapping.

2. The high quality of this machine, and its ease of operation makes it suitable for use by students, amateurs, and home hobbyists, as well as skilled technicians.

3. Drilling and milling may be done using hand operated feeding. Milling is done with the quill locked via Clamp Handle (#83) *.

4. Many of the adjustable nuts are bronze, for adjusting thread clearance and reducing wear. These bronze parts also allow screws to rotate smoothly and improve accuracy.

5. The vertical column is very strong and stiff, which makes the machine very stable and improves accuracy of manufactured parts.

6. The machine head is cast steel, and has been heat-treated, stress-relieved, and precision machined.

7. Machine gears are precision ground for smooth operation.

8. Speeds can be easily changed.

9. Thread tapping operations can be done in either rotation, and working depth can be controlled using a positive stop gauge.

SPECIAL WARNINGS WHEN USING THIS DRILLING / MILLING MACHINE

Using this machine may create special hazards.

Take particular care to safeguard yourself and those around you.

Electrical Safety. Never operate any tool if there is an electrical hazard. Never operate an electrical tool in wet conditions. Never operate a tool with an improper electrical cord or extension cord. Never operate an electrical tool unless you are plugged into a properly grounded outlet, which 60 Hz. We recommend you use a circuit which is protected by an appropriate circuit breaker.

Ejected Material. Use safe practices to avoid injury from ejected material. Because milling tools and workpieces turn at high speed, there is a danger of being injured by materials that may be ejected. Always wear ANSI-certified eye protection. Never attempt to machine any item if it is not adequately held. Always stand to one side of the plane in which the materials are spinning, to avoid being hit if an item is ejected. Never allow bystanders to be in the proximity of this machine while in operation.

Entanglement. Use extreme caution to prevent loose materials from being caught in the machine. Never operate this machine with loose clothing, long hair, jewelry, or other items which may become caught in the tool or workpieces. In case of entanglement, press the OFF switch immediately.
