B. Adjusting the Rocker Arm Pressure
The Rocker Arm pressure adjustment knob
increases or decreases the amount of pressure
applied to the material surface. This is
especially important when scoring glass, as too
much or too little pressure will create an
ineffective score, making the break out difficult.
1. Locate the knurled Rocker Arm Adjusting knob
(gold color) under the dual handle bar.
2. Insert the Glass Wheel Scoring tool holder into
the cutting head.
3. Make a test score on a scrap piece of glass. If the score line is too faint, turn the pressure
adjusting knob clockwise to increase the pressure.
4. If the score is rough and causes the glass to flake, there is excessive pressure. Turn the
adjusting knob counterclockwise to reduce the pressure.
C. Adjusting the Cutting Head Bearings
If the Cutting Head moves side-to-side too much, the
plastic bearings are worn or loose. You will need to make
adjustments using the small (3mm) Hex Key Wrench to
tighten the two (2) adjustment Screws on the front of the
Cutting Head.
♦ Note: Remove any Blade/Wheel Holders before
beginning the bearing adjustment.
1. Raise the Cutting Head to eye level to locate the
Bearing Adjustment Screws (see Figure on the
right).Using the 3mm Hex Key Wrench, turn both
Screws clockwise in increments of about one-eighth
(1/8) of a revolution (see Figure on the right).
2. Check to see if the bearings are no longer loose by
sliding the Cutting Head Assembly up and down the
Vertical Track Assembly.
3. Repeat Step 2 and 3 above until both the lateral
movement is minimized and the vertical movement of
the Cutting Head is smooth.
