[. . . ] Model Depressed center wheel diameter Spindle thread Rated speed (n) / No load speed (n0) Overall length Net weight Safety class · Specifications may differ from country to country. Due to our continuing programme of research and development, the specifications herein are subject to change without notice. Intended use The tool is intended for grinding, sanding and cutting of metal and stone materials without the use of water. Power supply The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. [. . . ] F) Use extra caution when making a "pocket cut" into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or objects that can cause kickback. Safety Warnings Specific for Sanding Operations: a) Do not use excessively oversized sanding disc paper. Follow manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending beyond the sanding pad presents a laceration hazard and may cause snagging, tearing of the disc or kickback. Safety Warnings Specific for Wire Brushing Operations: a) Be aware that wire bristles are thrown by the brush even during ordinary operation. Do not overstress the wires by applying excessive load to the brush. The wire bristles can easily penetrate light clothing and/or skin. B) If the use of a guard is recommended for wire brushing, do not allow interference of the wire wheel or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal forces. When using depressed centre grinding wheels, be sure to use only fiberglass-reinforced wheels. Be careful not to damage the spindle, the flange (especially the installing surface) or the lock nut. Damage to these parts could result in wheel breakage. Make sure the wheel is not contacting the workpiece before the switch is turned on. Before using the tool on an actual workpiece, let it run for a while. 2 The switch handle can be rotated to either 90° left or right to fit your work needs. Press the lock button and rotate the switch handle to left or right fully. the switch handle will be locked in that position. CAUTION: Always make sure that the switch handle is locked in the desired position before operation. Soft start feature These models begin to run slowly when they are turned on. CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. CAUTION: Always be sure that the side grip is installed securely before operation. [. . . ] Do not attempt to make an excessive depth of cut. Overstressing the wheel increases the loading and susceptibility to twisting or binding of the wheel in the cut and the possibility of kickback, wheel breakage and overheating of the motor may occur. Let the wheel reach full speed and carefully enter into the cut moving the tool forward over the workpiece surface. The wheel may bind, walk up or kickback if the power tool is started in the workpiece. [. . . ]
