- Electrical Safety: Power tool plugs must match the outlet. Never modify the plug in any way. Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators.
- Personal Safety: Always wear eye protection. Use hearing protection when operating noisy tools. Dress properly; avoid loose clothing or jewelry that can get caught in moving parts.
- Tool Use and Care: Do not force the power tool. Use the correct power tool for your application. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing power tools.
- Secure Workpiece: Always clamp or secure the workpiece firmly to the drill press table before drilling.
- Proper Ventilation: Ensure adequate ventilation when working with materials that produce dust or fumes.

Operating Instructions
Learn how to safely and effectively operate your bench drill machine.
1. Installing a Drill Bit
- Ensure the machine is unplugged from the power source.
- Open the chuck jaws using the chuck opener.
- Insert the drill bit into the chuck, ensuring it is centered and seated firmly.
- Tighten the chuck jaws securely using the chuck opener.
2. Adjusting Speed
The machine features an adjustable speed control switch (0-11000 RPM). Select the appropriate speed for your material and drill bit size. Lower speeds are generally used for larger drill bits and harder materials, while higher speeds are for smaller bits and softer materials.

3. Drilling Operation
- Secure Workpiece: Place the workpiece on the cast iron base and secure it firmly using clamps to prevent movement during drilling.
- Adjust Depth: Use the scale circle to set the desired drilling depth.
- Power On: Turn on the power switch.
- Lower Drill: Slowly lower the drill bit into the workpiece using the operating lever. Apply steady, even pressure.
- Retract Drill: Once the desired depth is reached, retract the drill bit from the workpiece.
- Power Off: Turn off the power switch and wait for the chuck to stop rotating before removing the workpiece.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your drill machine.
- Cleaning: After each use, unplug the machine and clean off any dust, chips, or debris from the machine, especially around the chuck, column, and motor vents. Use a brush or compressed air.
- Lubrication: Periodically apply a light machine oil to moving parts such as the column and spindle to ensure smooth operation.
- Chuck Care: Keep the chuck jaws clean and free of debris. If the chuck becomes stiff, clean it thoroughly and apply a small amount of lubricant.
- Carbon Brushes: Inspect carbon brushes periodically. Replace them when they are worn down to approximately 1/4 inch (6mm) or if the motor performance degrades. (Replacement carbon brushes are included).
- Belt Tension: Check the rubber belt tension regularly. Adjust or replace the belt if it appears loose or worn.
- Storage: Store the drill machine in a dry, clean, and secure location, out of reach of children.
