•lead from
•crystalline silica from bricks and cement and other masonry products
•arsenic and chromium from
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your ex- posure to these chemicals: work in a well ventilated area and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
Tool Use and Care
•Do not use if switch does not turn it ON or OFF. Any tool that cannot be controlled with the switch is dangerous and must be repaired.
•Disconnect the plug from the power source before making any adjustments, changing accessories or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.
•Store idle tools out of the reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
•Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the tool’s operation. If damaged, have the tool serviced before using. Many acci- dents are caused by poorly maintained tools.
•Use only accessories that are recommended for your tool. Accessories that may be suitable for one tool may become hazardous when used on another tool.
•Keep handles dry and clean; free from oil and grease. Allows for better control of the tool.
Service
•Tool service must be performed only by qualified re- pair personnel. Service or maintenance performed by unqualified repair personnel could result in injury.
•When servicing a tool, use only identical replace- ment parts. Follow instructions in the Maintenance Section of this manual. Use of unauthorized parts or failure to follow maintenance instructions may create a risk of electrical shock or injury.

Machine Safety
•Core Drilling Machine is made to drill holes in granite, masonry and steel reinforced concrete. Follow instructions on proper use of this machine. Do not use for other purposes. Other uses or mod- ifying this machine for other applications may increase the risk of serious injury.
•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.
•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.
•Keep fingers and hands away from drill bit. This practice will prevent entanglement and reduces risk of being cut.
•Secure drill stand to the work surface. Use bolts, ceiling jack or vacuum
•When releasing carriage locking handle, maintain a firm grip on feed handle to prevent feed handle from revolving due to weight of drill. Rotating han- dle can result in injury.
•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.
