The specifications for the MAKITA DGA518 and related cordless angle grinder models are as follows:

To install the battery cartridge: Align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely.

To remove the battery cartridge: Slide it from the tool while sliding the button on the front of the cartridge.

CAUTION: Always switch off the tool before installing or removing of the battery cartridge. Hold the tool and the battery cartridge firmly when installing or removing battery cartridge.

When you turn the tool on, the battery indicator shows the remaining battery capacity. The remaining battery capacity is shown in the following table:

Press the check button on the battery cartridge to indicate the remaining battery capacity. The indicator lamps light up for a few seconds.

The tool is equipped with a tool/battery protection system. This system automatically cuts off power to the motor to extend tool and battery life. The tool will automatically stop during operation if the tool or battery 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 automatically stops without any indication. In this situation, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart.
• Overheat protection: When the tool is overheated, the tool stops automatically and the battery indicator shows the following state. In this situation, let the tool cool before turning the tool on again.
• Overdischarge protection: When the battery capacity is not enough, the tool stops automatically. In this case, remove the battery from the tool and charge the battery.
• Releasing protection lock: When the protection system works repeatedly, the tool is locked. In this situation, the tool does not start even if turning the tool off and on. To release the protection lock, remove the battery, set it to the battery charger and wait until the charging finishes.

To prevent the switch lever from being accidentally pulled, a lock-off lever is provided.

1. To start the tool, pull the lock-off lever toward the operator and then pull the switch lever.
2. To stop the tool, release the switch lever.

CAUTION: Do not pull the switch lever hard without pulling the lock-off lever. This can cause switch breakage. Before installing the battery cartridge into the tool, always check to see that the switch lever actuates properly and returns to the “OFF” position when released.

The rotation speed of the tool can be changed by turning the speed adjusting dial. The table below shows the number on the dial and the corresponding rotation speed.

NOTICE: If the tool is operated continuously at low speed for a long time, the motor will get overloaded, resulting in tool malfunction. When changing the speed dial from “5” to “1”, turn the dial counterclockwise. Do not turn the dial clockwise forcibly.

Screw the side grip securely on the position of the tool as shown in the figure (on the gear housing).

CAUTION: Always be sure that the side grip is installed securely before operation.
