Instructions for use:
Step 1: Unscrew the metal ball and put oil in the tool; it will keep the cutter sharp longer.
Step 2: Measure with a ruler and clearly mark the parts to be cut with a pencil.
Step 3: Keep the handle and glass at an angle of about 60°.
Step 4: Cut along the marking line with a glass cutter, fast cut with a positive grating sound.
Step 5: Use the round ball on the end of the back end of the tool to tap the underside of the glass at an edge until you get a small crack. Then insert the ball under the glass.
Step 6: Press with your hands (preferably in gloves) on both sides of the scored line, and simply break it open.
Tips:
1. The glass cutter can not be used to cut high hardness objects, such as tempered glass, marble, etc.
2. When cutting mirrors with a glass cutter, the line must be scribed with the glass side facing up, not the aluminum foil side at the bottom.
3. When cutting thick glass or porcelain tiles, you must use a glass breaker as a tool.
