Safety for Drill Presses

1.EYE/FACE/HAND PROTECTION. A face shield used with safety glasses is rec- ommended. Always keep hands and fin- gers away from the drill bit. Never hold a workpiece by hand while drilling! DO NOT wear gloves when operating the drill.

2.SECURING BIT. Properly tighten and securely lock the drill bit in the chuck.

3.CORRECT BIT. Use only round, hex, or triangular shank drill bits.

4.ADJUSTING KEYS AND WRENCHES. Remove all adjusting keys and wrenches before turning the machine ON.

5.DRILLING SHEET METAL. Never drill sheet metal unless it is securely clamped to the table.

6.SURFACE/WORKPIECE PREP. Never turn the drill press ON before clearing the table of all objects (tools, scrap wood, etc.) DO NOT drill material that does not have a flat surface, unless a suitable support is used.

7.DAMAGED TOOLS. Never use tools in poor condition. Dull or damaged cutting tools are hard to control and may cause serious injury.

8.DRILL OPERATION. Never start the drill press with the drill bit pressed against the workpiece. Feed the drill bit evenly into the workpiece. Back the bit out of deep holes.

Turn the machine OFF and clear chips and scrap pieces with a brush. Shut power OFF, remove drill bit, and clean table before leav- ing the machine.

9.OPERATING SPEED. Always operate your drill press at speeds that are appropriate for the drill bit size and the material that you are drilling.

10.MAINTENANCE/SPEED CHANGES. Never do maintenance or change speeds with the machine plugged in.

11.MOUNTING WORKPIECES. Use clamps or vises to secure workpiece before drill- ing. Position work so you avoid drilling into the table.

12.TABLE LOCK. Make sure the table lock is tightened before starting the drill press.

13.EXPERIENCING DIFFICULTIES. If at any time you are experiencing difficulties performing the intended operation, stop using the machine! Contact our Service Department at (570) 546-9663.

Like all machines there is danger associated with this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to lessen the possibility of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur.

No list of safety guidelines can be complete. Every shop environment is different. Always consider safety first, as it applies to your individual working conditions. Use this and other machinery with caution and respect. Failure to do so could result in serious per- sonal injury, damage to equipment, or poor work results.
