How do you select the proper bit or attachment?
• Follow manufacturers' instructions when selecting and using a bit or attachment, especially with unfamiliar drills or work.
• Select the bit or attachment suitable for the size of the drill and the work being done.
• Ensure that the bit or attachments are properly seated and tightened in the chuck.
• Use only bits and attachments that turn true.
• Use the auxiliary (second) handle for larger work or continuous operation.
What should you do when working with powered hand drills?
• Wear safety glasses or a face shield.
• Keep drill air vents clear to maintain adequate ventilation.
• Keep drill bits sharp always.
• Keep all cords clear of the cutting area during use. Inspect for frays or damage before each use.
• Disconnect power supply before changing or adjusting bit or attachments.
• Tighten the chuck securely. Remove chuck key before starting drill.
• Secure workpiece being drilled to prevent movement
• Slow the rate of feed just before breaking through the surface.
• Drill a small "pilot" hole before drilling large holes.
What should you do when working with small pieces?
• Clamp stock so work will not twist or spin.
• Do not drill with one hand while holding the material with the other.
What should you avoid when working with powered hand drills?
• Do not use a bent drill bit.
• Do not exceed the manufacturer's recommended maximum drilling capacities.
• Do not use a hole saw cutter without the pilot drill.
• Do not use high speed steel (HSS) bits without cooling or using lubrication.
• Do not attempt to free a jammed bit by starting and stopping the drill. Unplug the drill and then remove the bit from the workpiece.
• Do not reach under or around stock being drilled.
• Do not overreach. Always keep proper footing and balance.
• Do not raise or lower the drill by its power cord.
• Do not use in wet or muddy locations. Use a nonpowered drill instead.
• Do not use excessive force to drill into hard material. Reduce drill speed if possible.
The following general precautions should be observed by power tool users:
• Never carry a tool by the cord or hose.
• Never yank the cord or the hose to disconnect it from the receptacle.
• Keep cords and hoses away from heat, oil, and sharp edges.
• Disconnect tools when not in use, before servicing, and when changing accessories such as blades, bits and cutters.
• All observers should be kept at a safe distance away from the work area.
• Secure work with clamps or a vise, freeing both hands to operate the tool.
• Avoid accidental starting. The worker should not hold a finger on the switch button while carrying a plugged-in tool.
• Tools should be maintained with care. They should be kept sharp and clean for the best performance. Follow instructions in the user's manual for lubricating and changing accessories.
• Be sure to keep good footing and maintain good balance.
• The proper apparel should be worn. Loose clothing, ties, or jewelry can become caught in moving parts.
• All portable electric tools that are damaged shall be removed from use and tagged "Do Not Use."
