Instructions for Cutting Crown Molding Laying Flat and
using the Compound Features
1. Molding laying with broad back surface down flat on
saw table.
2. The settings below are for All Standard (U.S.) crown

When setting bevel and miter angles for all compound
miters, remember that:
The angles presented for crown moldings are very
precise. Since they can easily shift slightly and very
few rooms have exactly square corners, all settings
should be tested on scrap molding.
PRETESTING WITH SCRAP MATERIAL IS
EXTREMELY IMPORTANT!
CUTTING PLASTIC PIPE AND OTHER ROUND
CROSS-SECTIONAL MATERIAL
Plastic pipe and similar material can be easily cut with your
saw. It should be cut just like wood and CLAMPED OR HELD
FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING
ESPECIALLY WHEN USING BEVEL OR MITER
FEATURES.
CUTTING LARGE MATERIAL
Occasionally you will encounter a piece of wood a little too
large to fit beneath the blade guard. A little extra clearance
can be gained by using one hand to roll the guard out of the
way as shown in figure 34. Trap the guard with the index fing-
er of the hand operating the trigger. Use the other hand to hold
the workpiece at a safe distance from the blade. Avoid doing
this as much as possible. However, the saw will operate
properly and make the

deeper cut with the guard
rolled up. NEVER TIE, TAPE,
OR OTHERWISE HOLD
THE GUARD OPEN WHEN
OPERATING THIS SAW.
GROOVING
Your sliding compound
miter saw is equipped with
a grooving lever and
thumbscrew and wingnut to
allow for groove cutting.
To use the grooving feature,
flip the grooving lever toward the front of the saw, as shown in
figure 35. In order to cut a groove of constant depth, place a
block of wood at least 2" wide against the fence. Otherwise,
the groove will be less deep near the fence.
Loosen the wingnut and adjust the thumbscrew to change the
depth of the groove cut. To lock the thumbscrew in position,
retighten the wingnut. ALWAYS MAKE DRY RUNS
(UNPOWERED) BEFORE FINISH CUTS SO THAT YOU
CAN CHECK THE DEPTH OF THE BLADE.
NOTE: Your saw is not designed for use with dado blades.

Installing a New Saw Blade

CAUTION: Disconnect the saw from the power supply
before making any adjustments. Before installing or removing
a blade, always lock the miter adjustment/lock handle, lock
the rail lock knob, and lock the bevel adjustment/lock handle.
Never depress the spindle lock button while the blade is
rotating.
CAUTION: Do not cut any ferrous metal (that with any
iron or steel content), masonry, or any fiber cement pro-
ducts with this saw.
REMOVING THE BLADE
1. Loosen but do not remove the arbor cover screw and pivot
the arbor cover up as shown in figure 36.

2. Engage the spindle lock by depressing the spindle lock
button shown in figure 4 and rotating the blade by hand
until you feel the spindle lock.
3. While continuing to depress the spindle lock button, loosen
the blade screw by turning it clockwise. Note that this
screw has left hand threads.
4. Remove the blade screw, outer clamp washer and blade.
REPLACING THE BLADE
1. Install the inner clamp washer
2. If you are using a blade with a 1" arbor hole, install the
blade adaptor.
3. Install the blade. If you are using a blade with a 1" arbor
hole, make sure that the arbor hole in the blade fits on the
blade adaptor. If you are using a blade with a 5/8" arbor
hole, make sure that the blade fits snuggly against the
inner clamp washer. Be sure that the teeth at the bottom of
the blade are pointing toward the rear of the saw, away
from the operator.
4. Install the outer clamp washer and blade screw. Tighten
the blade screw by turning it counterclockwise while
depressing engaging the spindle lock.
CAUTION: When using saw blades with 5/8" (15.8 mm)
arbor holes, remove the blade adaptor. Place it in a safe place
for future use.
5. Replace the arbor cover and tighten the arbor cover
screw.
CAUTION: Leaving the arbor cover unsecured may cause
blade screw and blade separation from the spindle shaft.
BE SURE TO HOLD THE GUARD BRACKET DOWN
AND FIRMLY TIGHTEN THE GUARD BRACKET SCREW
WHEN YOU FINISH INSTALLING THE SAW BLADE.
FAILURE TO DO SO WILL CAUSE SERIOUS DAMAGE
TO THE SAW AND POSSIBLE PERSONAL INJURY.
