7. Use only flanges specified for this tool. 8. 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. 9. NEVER use tool with wood cutting blades or other sawblades. Such blades when used on a grinder frequently kick and cause loss of control leading to personal injury. 10. Hold the tool firmly. 11. Keep hands away from rotating parts. 12. Make sure cord is clear of wheel. Do not wrap cord around your arm or wrist. If control of tool is lost, cord may become wrapped around you and cause personal injury. 13. Make sure the wheel is not contacting the workpiece before the switch is turned on. 14. Before using the tool on an actual work- piece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced wheel. 15. Use the specified surface of the wheel to perform the grinding. 16. Watch out for flying sparks. Hold the tool so that sparks fly away from you and other persons or flammable materials. 17. Do not leave the tool running. Operate the tool only when hand-held. 18. Do not touch the workpiece immediately after operation; it may be extremely hot and could burn your skin. 19. ALWAYS wear proper apparel including long sleeve shirts, leather gloves and shop aprons to protect skin from contact with hot grindings. 20. Use of this tool to grind or sand some products, paints and wood could expose user to dust containing hazardous substances. Use appropriate respiratory protection.

Shaft lock 001035 O 1 1. Slide switch 001046 2 1 1. Speed adjusting dial CAUTION: • Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. Shaft lock CAUTION: • Never actuate the shaft lock when the spindle is moving. The tool may be damaged. Press the shaft lock to prevent spindle rotation when installing or removing accessories. Switch action CAUTION: • Before plugging in the tool, always check to see that the slide switch actuates properly and returns to the “OFF” position when the rear of the slide switch is depressed. • Switch can be locked in “ON” position for ease of operator comfort during extended use. Apply caution when locking tool in “ON” position and maintain firm grasp on tool. To start the tool, slide the slide switch toward the “I (ON)” position. For continuous operation, press the front of the slide switch to lock it. To stop the tool, press the rear of the slide switch, then slide it toward the “O (OFF)” position. Speed adjusting dial The rotating speed can be changed by turning the speed adjusting dial to a given number setting from 1 to 5. Higher speed is obtained when the dial is turned in the direction of number 5. And lower speed is obtained when it is turned in the direction of number 1. Refer to the table below for the relationship between the number settings on the dial and the approximate rotating speed. RPM (/min) 1 2,800 | | 2 4,000 | | 3 6,500 | | 4 9,000 | | 5 10,500 CAUTION: • If the tool is operated continuously at low speeds for a long time, the motor will get overloaded and heated up. • The speed adjusting dial can be turned only as far as 5 and back to 1. Do not force it past 5 or 1, or the speed adjusting function may no longer work. The tools equipped with electronic function are easy to operate because of the following features. • Electronic constant speed control Possible to get fine finish, because the rotating speed is kept constantly even under the loaded condition. • Soft start feature Soft start because of suppressed starting shock. • Overload protector When the tool would be employed over the admissible load, it will stop automatically to protect the motor and wheel. When the load will come to the admissible level again, the tool can be started automatically. ASSEMBLY CAUTION: • Always be sure that the tool is switched off and unplugged before carrying out any work on the tool. 002979 Installing side grip (handle) • CAUTION: Always be sure that the side grip is installed securely before operation. Screw the side grip securely on the position of the tool as shown in the figure. 002980 Installing or removing wheel guard 1 2 3 4 1. Wheel guard 2. Bearing box 3. Screw 4.
