Operating Instructions
Follow these steps for effective and safe operation of your TONE RMF-21 wrench:
1. Selecting the Correct End:

- Ratcheting Box End: Use the ratcheting box end for continuous turning of fasteners without removing the wrench, especially in tight spaces.

2. Adjusting the Flexible Head:
The ratcheting box end features a flexible head that can be adjusted to various angles. Gently pivot the head to the desired angle to access fasteners in obstructed areas. The head will hold its position during use.
3. Applying the Wrench:
- Place the appropriate end of the wrench fully onto the fastener. Ensure a snug fit to prevent rounding the fastener or slipping.
- For the ratcheting end, observe the directional arrow on the head. This indicates the tightening direction. To loosen, flip the wrench over or use the open end.
- Apply steady, even pressure to turn the fastener. Avoid sudden jerks or excessive force.

Proper maintenance ensures the longevity and performance of your TONE RMF-21 wrench:
- Cleaning: After each use, wipe the wrench clean with a dry cloth to remove dirt, grease, and debris. For stubborn grime, use a mild solvent and then wipe dry.
- Lubrication: Periodically apply a small amount of light machine oil to the flexible head pivot point and the internal ratchet mechanism (if accessible) to ensure smooth operation.
- Storage: Store the wrench in a clean, dry environment to prevent rust and corrosion.
- Inspection: Regularly inspect the wrench for wear, cracks, or damage. Pay close attention to the teeth of the ratchet mechanism and the integrity of the flexible joint. Replace the tool if significant wear or damage is found.
