SAFETY INSTRUCTIONS

Keep your work area clean and well-lit. Always keep the work area free of obstructions, grease, oil, trash, and other debris.
Never operate this machine in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or fumes.
Keep bystanders, children, and visitors away while operating this machine. Distractions can lead to serious injury or property damage. Protect others in the work area from debris such as chips and sparks. Provide barriers or shields as needed.
Never leave the drill press unattended while running.
Do not touch grounded surfaces such as pipes, radiators, ranges, and refrigerators when operating on electrical components. There is an increased risk of electric shock if your body is grounded.
Do not expose the machine to water. Water entering a power tool will increase the risk of electric shock.
Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all local codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use adapter plugs. Check with a qualified electrician if you are unsure if the outlet is properly grounded. If the tools should electrically malfunction, grounding provides a low resistance path to carry electricity away from the user.
Do not use a drill press if the power switch does not work. Cease operation and repair switch or replace drill press.
Keep the Power Cord away from heat, oil, sharp edges, or moving parts. Cease operation and replace Power Cords immediately if damaged.
Disconnect the power cord before making any adjustments, maintenance, or storing the machine.
Avoid Accidental start-ups, make sure the power switch is in the “OFF” position before plugging in the power cord.
Never use this machine when tired or under the influence of drugs, alcohol, or medication.
Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts and may cause serious personal injury.
Remove adjusting keys or wrenches before turning the drill press on. A wrench or a key that is left attached to a rotating part of the machine is dangerous and may result in personal injury.
Do not start the motor with the drill bit touching the workpiece, this can cause the workpiece to catch and spin with the bit. Allow the bit to come up to full speed before you begin drilling.
Use safety equipment, drill presses can produce sharp chips which can cause permanent eye damage if lodged in the eye. Wear ANSI Z87+ safety glasses or goggles for protection.
Secure the workpiece using clamps or a vise whenever possible. Especially when drilling large holes, or any size hole in sharp objects or sheet metal, the workpiece may become a hazard if it is caught and rotated by the drill bit. Clamping the workpiece is more secure than using your hands and keeps them out of harm’s way.
Do not use third-party or aftermarket accessories, they may impair the operation of the drill press or malfunction during normal use.
Maintain all labels and nameplates on the machine so that they are clearly visible and legible.

OPERATION INSTRUCTIONS

Install the machine on a flat, level bench top that is sturdy enough to support the weight and vibrations of the drill press.
Always wear protective safety glasses or goggles when operating the machine.
Clear woodchips, sawdust, and metal chips before operation.
Make sure head and table supports are secure before drilling
Check all nuts, bolts, and screws for tightness regularly. Vibration during operation may cause hardware to loosen.
Use the correct drill bit. Ensure that you have selected the correct drill bit and drill speed based on the workpiece’s material and thickness. Ensure that there are no nails or other hard objects in the path of the drill bit. Take care not to force the drill bit, you may permanently damage the bit and the workpiece.
Do not use a drill bit longer than 175mm (150mm outside chuck jaws).
Do not place drill bit against workpiece before turning the power switch on. Turn on the drill before and allow the bit to come up to full speed before drilling.
Make sure you are drilling at the correct speed based on hole size and workpiece material.
Make sure there are no nails or other hard obstacles in the way of the drill bit inside the workpiece
Jog the motor before drilling to ensure that the drill bit is secure and the motor is in working order.
Hold the workpiece securely at a safe distance from the drill bit or use clamps or vise. Never drill into an unsecured workpiece.

OPERATION

Properly adjust Drill Press components before drilling

Set the table to the preferred height by undoing the cable clamp bolt and turning the lifting crank. Tighten the clamp bolt once desired height has been reached.
To rotate the table, loosen the cable clamp bolt and rotate the table to the desired position. Tighten the clamp bolt when a position is achieved.
Set table angle by loosening the table lock bolt and adjusting the table to the desired angle. When the desired angle is achieved, secure the lock bolt.
Drill feed depth can be adjusted. To adjust feed depth, loosen the feed locking screw and rotate the scale to the desired height, then tighten the locking screw. Adjust the scale to drill different holes to equal depths.
The spindle can be locked at different heights. Set the spindle to the desired height using the feed crank, then tighten the feed crank set screw. This feature is useful for aligning workpieces.
Speed can be adjusted by changing the belt location. Open the belt box in the Head Assembly, loosen the belt tensioning lock knob, pull the motor mounting plate to the front and then move the belt to the desired pulleys. Refer to Spindle Speed Table for pulley speeds. When Belt is mounted, push the motor mounting plate back to the rear and lock the belt tensioning knob. NOTE: Drill speed is determined based on the workpiece material and drill bit type and thickness. Consult drill speed chart to determine required speed (next page).
