Cutting Base Molding; Cutting Crown Molding - Genesis GMS1015LC Manuel D'utilisation

CUTTING BASE MOLDING

Base molding can be cut using two methods: standing vertically against the fence or horizontally, laying flat on the
miter table. using the vertical method is limited by the height capacities of your compound miter saw.
Flat or Horizontal Cutting:
1. Lay the base molding's back onto the miter table with the bottom of the base molding placed against the
fence.
2. Set the miter angle to 0°.
3. Turn on the laser and set the blade's bevel to the desired angle, such as 45° for one half of 90° corners.
4. Align the cut line on the workpiece with the blade and laser light.
5. Confirm the saw settings, turn on the saw and make the cut as described earlier.
Vertical Cutting
:
1. Stand the base molding upwards with the molding back against the fence and molding bottom sitting on the
miter table.
2. Set the bevel angle to 0°.
3. Turn on the laser and set the miter table to the desired angle, such as 45° for one half of 90° corners.
4. Align the cut line on the work piece with the blade and laser light.
5. Confirm the saw settings, turn on the saw and make the cut as described earlier.

CUTTING CROWN MOLDING

Your compound miter saw is the ideal tool for cutting crown molding, which bridges the wall and ceiling. The
most common style of crown molding used today has a top rear angle of 52° at the ceiling and a bottom rear
angle of 38° where it meets the wall. for an installation with tight fitting corners where the right and left pieces
meet, extremely accurate bevel and miter angle settings are required.
There are two methods for cutting crown molding. 1) Cutting
Crown Molding flat on the Miter Table. 2) Cutting Crown Molding
Vertically Nested against Miter fence.
Cutting Crown Molding Flat on the Miter Table
Since the most common corners encountered when using
crown molding measure 90° inside and outside, the following
instructions will be for cutting 52°/38° crown molding to fit 90°
corners with the molding laying flat on the saw table.

Left Side,
1. Top edge of molding against fence
2. Miter table set RIGHT to 31.62°
3. Bevel set at 33.85° Left
4. Save LEfT end of cut
Right Side
1. Bottom edge of molding against fence
2. Miter table set LEfT to 31.62°
3. Bevel set at 33.85° Left
4. Save LEfT end of cut
note:
When cutting and installing crown molding keep in mind the bevel and miter angles involved are
extremely accurate while the corners you'll be working on will rarely measure exactly 90°. Therefore, be prepared
to make numerous practice cuts with scrap molding to help fine tune your saw settings.
for cutting crown molding flat for corners other than 90°, please refer to Crown Molding Miter Angles chart.
Cutting Crown Molding Vertically Nested Against Miter Fence
Always use a crown molding fence when cutting crown molding angled against the fence. Cutting crown molding
angled against the fence does not require any special bevel settings. Small changes in the miter angle can be
made without affecting the bevel angle. When using this method the saw can be quickly and easily adjusted for
corners that are not 90° (square).
