E. Proper Glass Scoring and Breaking Techniques
CAUTION:
; Always wear eye protection, gloves, and protective clothing when handling glass.
; Always load glass from the left side of the machine.
; Glass should not extend beyond the edges of the Horizontal Material Bar.
; Always score in a downward stroke.
Scoring Glass
♦ Notes:
• Never score glass more than once on the same line.
• A light, continuous score line is best.
• If there is too much pressure, the score line will be flaky
1. Insert the Glass Scoring Wheel Holder into the Cutting Head.
2. Position the glass sheet on the left side of the Horizontal Material Bar.
3. Align the left edge of the glass with the desired measurement on the scale.
4. Gently
apply the Clamp.
5. Grasp the handle, depress the Thumb Lever to retract the tool, and raise the
Cutting Head well above the upper edge of the glass.
6. Release the Thumb Lever, and bring the Cutting Head down slowly until you feel
the Wheel Ramp contact the glass.
7. Bring the Cutting Head down to the bottom resting position using one continuous
motion.
¾ Tip: If the glass is flaky there is too much pressure on the Rocker Arm.
Refer to “Adjusting the Rocker Arm Pressure
,” Section 6.2 on page 31
for more information.
Breaking Glass Along a Score Line
♦ Note: For proper breakout of glass, there must be at least 2¾" (~70mm) of
material to the right of the score line. Smaller sections must be
removed from the machine and broken out on your workbench.
CAUTION: Do not apply pressure at the center of the glass score line.
1. Place your thumb just to the right of the score at the top of the glass sheet.
2. Apply just enough pressure until the score “runs” downward and the glass breaks
cleanly along the score line.
3. Release the clamp.
