Proper Glass Scoring and Breaking Techniques
CAUTION:

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.
A.
Scoring Glass
♦
Notes:
•
Never score the same place more than once.
•
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, and raise the Cutting Head well
above the glass.
6.
Release the Thumb Lever, and bring the Cutting Head down until you feel the
Wheel Ramp contact the glass.
7.
Bring the Cutting Head down to the resting position using one continuous motion.

Tip: If the glass is flaky there is too much pressure on the Rocker Arm.
Refer to “Adjusting the Rocker Arm,” Section 44.-B. on page 28 for
more information.
B.
Breaking Glass Along a Score Line
♦
Note: For proper breakout of glass, there must be at least 2¾" (69.8 mm) 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.
1.
Place your thumb at the bottom right corner of the glass.
2.
Apply just enough pressure until the glass breaks.
3.
Release clamp.
