操作手順
The Neiko 1/2-Inch Drive Ratchet Wrench is designed for efficient tightening and loosening of fasteners.
方向転換:
- Locate the small lever (flip switch) on the drive head.
- To tighten (clockwise rotation), push the lever to one side.
- To loosen (counter-clockwise rotation), push the lever to the opposite side.
- Ensure the lever is fully engaged in the desired direction before applying torque.
トルクの適用:
- With the correct socket attached and the direction set, place the socket onto the fastener.

メンテナンス
Proper maintenance will extend the life and performance of your Neiko Ratchet Wrench.
