Slide Cuts; Tips For Cutting Crown Molding - Delta 26-2240 Manual De Instrucciones

SLIDE CUTS

A slide cut should never be performed by
pulling the saw toward you. Due to the blade rotation
direction, this can cause the saw blade to climb over the
workpiece and towards the operator. Failure to follow this
warning could result in serious personal injury.
Before turning the saw power ON, check to
make sure saw head and blade will not make contact with the
provided work clamp or fence during the cutting operation.
Position the work clamp and fence to avoid contact with the
miter saw head.
See Figure 22
To use this saw to make slide cuts follow the instructions
below. Slide cuts must only be performed by pushing the saw
blade away from you and toward the back of the saw, stopping
at the fully RETRACTED position after each cut. See warning
above.
1.
Check to make sure the slide prevention lock (B) and head
lock pin (A) is not engaged. Raise the saw head to its UP
position.
2.
Position the workpiece so that it is securely supported by
the saw table and fence. If the board is warped, read and
follow the instructions under "Cutting Warped Material" in
the "Operation" section of this manual.
3.
Secure the workpiece to the table and against the fence,
using the provided clamp.
4.
Before turning the power switch ON, perform a simulated
cut to check your cut alignment. Also check to make sure
the blade will not come into contact with the provided
work clamp or anything other than the workpiece.
5.
Before turning the power switch ON, pull the saw arm
towards you until the blade is beyond the front edge
of your workpiece or until the saw arm is in the fully
EXTENDED position. The saw head should be in the full UP
position.
6.
Engage the power ON switch. Allow the blade to reach
maximum speed.
7.
Lower the saw blade through the workpiece and push the
saw head towards the fully RETRACTED position.
8.
Disengage the power switch and allow blade to come to a
complete stop before raising the saw head.

TIPS FOR CUTTING CROWN MOLDING

• The two edges of the molding that contact the ceiling and the 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°.
• To accurately cut crown molding for a 90° inside or outside corner, lay the molding with its broad back surface flat on the miter
table and against the fence.
• The angles for crown moldings must be very precise. The bevel and miter angles are interdependent; changing one angle
changes the other angle as well.
• Since it is very easy for the work piece to shift, all settings should first be tested on scrap molding. Also most walls do not have
angles of exactly 90°; therefore, you will need to fine-tune your settings.
• When cutting crown molding the bevel angle should be set at 33.85°.
• The miter angle should be set at 31.62° either right or left, depending on the desired cut for the application. See the chart
below for correct angle settings and correct positioning of crown molding on the work table.
