2. Setup and Blade Installation
Before using the carpet cutter, ensure that the blades are correctly installed and secured. The cutter is designed for easy blade insertion and secure locking.
2.1. Blade Installation
- Identify Blade Screws: Locate the two screws on the side of the cutter near the handle that secure the blade mechanism.
- Loosen Screws: Using an appropriate screwdriver, loosen the second screw from the hand grip. This will allow the blade holder to move.
- Insert Blade: Carefully slide a new blade into the designated slot. Ensure the blade is oriented correctly with the cutting edge facing outwards. The cutter accommodates a 2-blade design.
- Secure Blade: Once the blade is in position, tighten the loosened screw to firmly secure the blade. The direct contact locking design ensures the blade remains in place during use.
- Verify Security: Gently tug on the blade to confirm it is securely locked and does not wobble.
