[. . . ] 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. [. . . ] C) When wheel is binding or when interrupting a cut for any reason, switch off the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the cut-off wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminate the cause of wheel binding d) Do not restart the cutting operation in the workpiece. The wheel may bind, walk up or kickback if the power tool is restarted in the workpiece. E) Support panels or any oversized workpiece to minimize the risk of wheel pinching and kickback. Supports must be placed under the workpiece near the line of cut and near the edge of the workpiece on both sides of the wheel. 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. 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. 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. Make sure the wheel is not contacting the workpiece before the switch is turned on. 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. 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. [. . . ] Use of damaged wire wheel brush could increase potential for injury from contact with broken wires. ALWAYS use guard with wire wheel brushes, assuring diameter of wheel fits inside guard. Wheel can shatter during use and guard helps to reduce chances of personal injury. CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance. [. . . ]
