To prevent serious injury, inspect your Core Drilling Machine. The following inspection proceduresshould be performed on a daily basis:

  1. Make sure Core Drilling Machine is unplugged and the drill mast switch is set to the OFF position.
  2. Inspect the vacuum seal for wear or damage. Replace if necessary.
  3. Inspect the power cord and plug for damage. If the plug has been modified, is missing the grounding prong or if the cord is damaged, do not use the Threading Machine until the cord has been replaced.
  4. Inspect the Core Drilling Machine for any broken, missing, misaligned or binding parts as well as any other conditions which may affect the safe and normal operation of the machine. If any of these conditions are present, do not use the machine until any problem has been repaired.
  5. Lubricate the Core Drilling Machine if necessary according to the Maintenance Instructions.
  6. Use drill bits and accessories that are designed for your Core Drilling Machine and meet the needs of your application. The correct tools and accessories allow you to do the job successfully and safely. Accessories designed for use with other equipment may be hazardous when used with the Core Drilling Machine.
  7. Clean any oil, grease or dirt from all handles and controls. This reduces the risk of injury due to a tool or control slipping from your grip.
  8. Inspect the cutting edges of your drill bits. If necessary, have them replaced prior to using the Core Drilling Machine. Bit is considered worn when the crown shows excessive wear and has become flush with tube. Dull or damaged cutting tools can lead to binding and tool breakage.

Once the machine is inspected, follow the following guidelines during operation.

  1. The Core Drilling Machine is made to drill holes in granite, masonry and steel reinforced concrete. Follow instructions on proper use of the machine. Do not use for other purposes. Other uses or modifying this machine for other applications may increase the risk of serious injury.
  2. Do not wear loose cloth gloves or loose clothing when operating machine. Wear only leather gloves. Keep sleeves and jackets buttoned. Do not reach across the machine or drill bit. Clothing can be caught by the machine resulting in entanglement and serious injury.
  3. Use extreme caution when drilling through floors. Provide protection of all personnel and material below the area. Cores generally drop from the drill at completion of the hole.
  4. Keep fingers and hands away from drill bit. This practice will prevent entanglement and reduces risk of being cut.
  5. Secure drill stand to the work surface. Use bolts, ceiling jack or vacuum hold-down. Do not secure with a vacuum hold-down when drilling on vertical surfaces such as walls. Drill stand must be properly secured to prevent bit damage and serious injury.
  6. When releasing carriage locking handle, maintain a firm grip on feed handle to prevent feed handle from revolving due to weight of drill. Rotating handle can result in injury.
  7. Do not force drill bit. Drill should be used at a speed and feed rate that does not overload the motor. When starting bits, do not use more than two 12 ? extensions. Less likely to bind and lose control.
