7 SAFETY RULES FOR THE DRILL PRESS 1.Drill bits larger than 3/8” are used at the slowest machine speed. 2.Remove the chuck key from the chuck before starting the machine. 3.Be careful of wind motion around the chuck. It will pull in loose hair and clothes. Copyright Texas Education Agency (TEA) 7

8 SAFETY RULES FORTHE DRILL PRESS 4. Remove all extra materials and tools from machine when in operation. 5. Clamp all small parts in a vise or clamp. 6. Use bits made with straight shanks to fit in drill chuck. Copyright Texas Education Agency (TEA) 8

9 Belt Disk Sander Copyright Texas Education Agency (TEA) 9

10 MAJOR PARTS OF THE BELT DISK SANDER Copyright Texas Education Agency (TEA) 10

11 MAJOR PARTS OF THE BELT DISK SANDER 1. The belt is the abrasive belt used to sand surfaces and edges. 2. The disk is the abrasive material cut in a disk and is used to sand edges and end grain. 3. The belt tracking knob is an adjustment to keep the belt on the sander wheels, which is called tracking. 4. The belt tension knob is used to tighten the belt in the machine. Copyright Texas Education Agency (TEA) 11

12 SAFETY RULES FOR THE BELT DISK SANDER 1. Be certain the belts and disk are correctly mounted. 2. Use the tables and fences to hold the material while sanding. 3. Small or irregular shapes should be held in clamps or in a special jig. Copyright Texas Education Agency (TEA) 12

13 SAFETY RULES FOR THE BELT DISK SANDER 4.Sand only on the downward side of the disk sander. 5.Sand only on clean wood, not painted, excessively glued or finished. 6.Keep the material moving across the abrasive to prevent burning due to friction. Copyright Texas Education Agency (TEA) 13

14 Portable Sanders Copyright Texas Education Agency (TEA) 14

15 DIFFERENT TYPES OF PORTABLE SANDERS Finish Sander Square Finish Sander Belt Sander Copyright Texas Education Agency (TEA) 15

16 SAFETY RULES PORTABLE SANDERS 1. Watch power cords on sanders. Do not get cords under sanders. 2. Clamp material to be sanded. 3. Use handles on equipment to protect your hands and control the tool. 4. Make all adjustments with the power cord unplugged. Copyright Texas Education Agency (TEA) 16

17 Routers Copyright Texas Education Agency (TEA) 17

18 DIFFERENT TYPES OF ROUTERS Copyright Texas Education Agency (TEA) Handheld RouterPlunge RouterTable Router 18

19 MAJOR PARTS OF THE ROUTER Copyright Texas Education Agency (TEA) Collet Bit Base Motor 19

20 MAJOR PARTS OF THE ROUTER 1.The base is the bottom portion where the handles and motor are located. 2.The motor is a high RPM electric motor that has the collet machined into the end of the shaft. 3.The collet is a tapered holding device used to hold the bits in the machine. Copyright Texas Education Agency (TEA) 20

21 SAFETY RULES FOR THE ROUTER 1. When using a hand held router, the work must be clamped down with a vise or a clamp. 2. Disconnect the router before changing the bit. 3. After adjusting the router depth, you should lock the motor and base together. 4. The router bit should be inserted at least 1 inch into the collet. 5.
