User manual MAKITA HR2811F

[. . . ] Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury. Safety equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries. [. . . ] Be careful not to scratch the lens of lamp, or it may lower the illumination. CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. Depress the reversing switch lever from the A side for clockwise rotation or from the B side for counterclockwise rotation. Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool. When you operate the tool in counterclockwise rotation, the switch trigger is pulled only halfway and the tool runs at half speed. CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released. For model HR2810T, HR2811FT The quick change chuck for SDS-plus can be easily exchanged for the quick change drill chuck.

Select one of the two modes suitable for your work needs by using this knob. For rotation only, turn the knob so that the arrow on the knob points toward the symbol on the tool body. For rotation with hammering, turn the knob so that the arrow on the knob points toward the symbol on the tool body. If you operate the tool with the knob positioned halfway between the mode symbols, the tool may be damaged. â· Use the knob after the tool comes to a complete stop. Grasp the change cover of the quick change drill chuck and set the line to the symbol.
