[. . . ] Failure to follow all instructions listed below may All of the warnings listed below refers to your mains-operated (corded) power tool or batteryoperated (cordless) power tool. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. If operating the power tool in damp locations is unavoidable a Ground Fault Circuit Interrupter (GFCI) must be used to supply the power to your tool. GFCI and personal protection devices like electrician's rubber gloves and footwear will further enhance your personal safety. [. . . ] Grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are: · lead from lead-based paints , · Crystalline silica from bricks and cement and other masonry products, and · arsenic and chromium from chemicallytreated lumber. Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure 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. Some dust created by IMPORTANT: Some of the following symbols may be used on your tool. Proper interpretation of these symbols will allow you to operate the tool better and safer. Rotational speed, at no load Higher number means greater speed Speed is increasing from 0 setting Action in the direction of arrow Type or a characteristic of current Type or a characteristic of current Type or a characteristic of current Designates Double Insulated Construction tools.

Disconnect the plug from the power source before making any assembly, Model number Shank style Maximum Capacities: Carbide tipped bits Thin wall core bits VARIABLE SPEED CONTROLLED TRIGGER SWITCH Your tool is equipped with a variable speed trigger switch. The tool speed can be controlled from the minimum to the maximum nameplate RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed. This accurate speed control enables you to drill without center punching. Bits are available for driving screws as well as running bolts and nuts. rEVERSING SWITCH LEVER This tool is equipped with a rotating brush reversing system. This results in longer brush life while maximizing power in both forward and reverse directions. The reverse switch can be operated from either the right or left side of the tool. Be aware that due to required clutch setting, you may experience a torque reaction an instant before the clutch slips. This torque reaction will twist the body of the rotary hammer in the opposite direction as the bit rotates, i. [. . . ] Complete the hole from the opposite side immediately after the point breaks through. if bit binds , reverse the drilling operation to help remove the bit from the work. First, the harder the material, the greater the pressure you need to apply to the tool. Lubricate the tip of the bit occasionally with cutting oil except when drilling If the hole to be drilled is fairly large, drill a smaller hole first, then enlarge to the required size, it's often faster in the long run.
