Craftsman 137.21214 Changing the Laser Batteries, Cutting Crown Molding FIG. AA, BB

CUTTING CROWN MOLDING (FIG. AA, BB)

Your compound miter saw is suited for the difficult task of cutting crown molding. To fit properly, crown molding must be compound-mitered with extreme accuracy.

The two surfaces on a piece of crown molding that fit flat against the ceiling and wall are at angles that, when added together equal exactly 90°.

Most crown molding has a top rear angle (the section that fits flat against the ceiling) of 52°and a bottom rear angle (the section that fits flat against the wall) of 38°.

In order to accurately cut crown molding for a 90° inside or outside corner, lay the molding with its broad back surface flat on the saw table.

When setting the bevel and miter angles for compound miters, remember that the settings are interdependent; changing one changes the other, as well. Also keep in mind that the angles from crown molding are very easy for these angles to shift slightly, all settings should be tested on scrap molding.

CHANGING THE LASER BATTERIES

CHANGING THE BATTERIES (Fig. CC)

Unplug your saw.

1

FIG. CC

Failure to unplug your saw could result in accidental starting causing possible serious personal injury.

1.Remove the laser guide from the saw.

2.Loosen and remove the two screws (1), then remove the laser guide cover.

3.Remove the three batteries by sliding them out from their mounting braces using a non-conductive devise such as a toothpick.

4.Replace the batteries that have a rating of 1.5 volts (Number LR44).

5.Replace the laser guide cover, two screws and

laser assembly onto the miter saw.

Note:

When replacing the batteries, the battery cover should be thoroughly cleaned. Use a soft paintbrush or similar device, to remove all sawdust and debris.
