5. Operating Instructions
This section details the proper procedure for using the Knipex Ratcheting Knife for cutting and stripping cables.
5.1 Preparing for a Cut
- Ensure the cable to be cut is de-energized and secured.
- Unlock the blade guard and extend the blade.
5.2 Making a Ratcheting Cut
- Position the knife around the cable at the desired cutting point.
- Apply gentle pressure and begin the ratcheting motion by squeezing the handles. The blade will advance through the cable with each squeeze.
- Continue the ratcheting action until the cable is fully cut.

5.3 Stripping Cable Insulation
For stripping cable insulation, the knife can be used to score the outer jacket.
- Position the blade to score the insulation without cutting into the conductors.
- Rotate the knife around the cable to create a circumferential score.
- Apply a longitudinal cut along the scored line if necessary.
- Carefully peel back and remove the insulation.

6. Maintenance
- Cleaning: After each use, wipe the knife clean of any debris or residue using a dry cloth. Avoid using harsh chemicals.
- Lubrication: Periodically apply a light machine oil to the pivot points and ratcheting mechanism to ensure smooth operation.
- Blade Inspection: Regularly check the blade for sharpness and damage. A dull blade requires more force and increases the risk of injury. Refer to Section 4 for blade replacement.
- Storage: Store the knife in a dry, secure location with the blade guard engaged, away from moisture and corrosive materials.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Knife not cutting effectively | Dull or damaged blade | Replace the blade (refer to Section 4). |
