Installing Bits
Always remove the battery before inserting or removing bits. Select the proper style and size bit for the job. This tool is equipped with a spindle lock. The chuck can be tightened with one hand, creating higher grip strengths on the bit.
1. To open the chuck jaws, turn the sleeve in the counterclockwise direction. When using drill bits, allow the bit to strike the bottom of the chuck. Center the bit in the chuck jaws and lift it about 1/16" off of the bottom. When using screwdriver bits, insert the bit far enough for the chuck jaws to grip the hex of the bit.
2. To close the chuck jaws, turn the sleeve in the clockwise direction. The bit is secure when the chuck makes a ratcheting sound and the sleeve can not be rotated any further.
3. To remove the bit, turn the sleeve in the counterclockwise direction. NOTE: A ratcheting sound may be heard when the chuck is opened or closed. This noise is part of the locking feature, and does not indicate a problem with the chuck’s operation.

安裝鑽頭
在插入或取出鑽頭之前，務必先取出電池。 為作業選擇合適的樣式和尺寸鑽頭。 該工具配有主軸鎖。 可以用一隻手擰緊夾頭，在鑽頭上產生更高的抓地力。
1. 要打開夾爪，逆時針轉動套筒。 使用鑽頭時，讓鑽頭撞擊卡盤底部。 將鑽頭置於夾爪中並將其從底部抬起約 1/16"。使用螺絲刀鑽頭時，將鑽頭插入足夠深的位置，使夾爪夾住鑽頭的六角形。
2. 要關閉夾爪， 順時針方向轉動套筒。當卡盤發出棘輪聲時，鑽頭已固定，套筒不能再旋轉。
3. 要卸下鑽頭，逆時針方向轉動套筒。注意：可能會發出棘輪聲 打開或關閉卡盤時會聽到這種聲音。
這種噪音是鎖定功能的一部分，並不表示卡盤的操作有問題。

衝擊起子、震動電鑽由於機構必須有敲擊、震動功能，所以通常偏心度比較大。
（隨著使用時間久了會更大…）
偏心度越大，鑽出來的洞越大。
