FUNCTIONAL DESCRIPTION CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool. Tool protection system The tool is equipped with a tool protection system. This system automatically reduces or cuts off power to the motor to extend tool life. The tool will automatically reduce power or stop during operation if the tool is placed under one of the following conditions: Overload protection When the tool is operated in a manner that causes it to draw an abnormally high current, the tool reduces power automatically without any indication. In this situation, remove the cause of the overload so that the rotation speed recovered. Overheat protection Country specific When the tool is overheated, the tool stops automatically and the indication lamp blinks in red. In this situation, let the tool cool down. You can turn the tool on again after the lamp changes the color from red to green. Indication lamp Speed adjusting dial Only for model GA4593 / GA5093 CAUTION: If the tool is operated continuously at low speeds for a long time, the motor will get overloaded and heated up. CAUTION: 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 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 below table for the relationship between the number settings on the dial and the approximate rotating speed.
