CROWN MOLDING CUT (FIG. 29)
1. Crown molding can only be cut flat on
the table for this miter saw.
2. This miter saw has special miter stops
of 31.6° left and right and a bevel stop
of 33.9° for a special crown molding, i.e.
52° between the back of the molding
and the top flat surface that fits against
the ceiling; 38°
between the back of
the molding and the bottom flat surface
that fits against the wall. Refer to the
following table below for this crown
molding cut.
NOTE:
1. These special stops can not be used
with 45° crown molding.
2. Since most rooms do not have angles
of exactly 90°, fine tune is needed and
always take a test cut to confirm the
correct angles.

WARNING!
Never pull the cutting head assembly
and spinning blade toward you
during the cut. The blade may try to
climb up on the top of the workpiece,
causing the cutting assembly
and spinning blade to kick back
forcefully. The cutting head assembly
should be drawn back completely
then pushed forward when sawing.
11
1. Unlock the slide carriage lock knob (1)
and allow the cutting head assembly to
move freely.
2. Set both the desired bevel angle and/or
the miter angle and lock into position.
3. Use a hold-down clamp to secure
the workpiece.
4. Grasp and pull the switch handle (2)
forward until the center of the saw blade
is over the front of the workpiece (3).
5. Pull the trigger to turn the saw on.
6.
When the saw reaches full speed,
push the switch handle down, slowly,
cutting through the leading edge of
the workpiece (3).
7. Slowly move the switch handle (2)
toward the fence, completing the cut.
8. Release the trigger and allow the blade
to stop spinning before allowing the
cutting head to raise.
CARRYING THE TOOL
(FIG. 2)
NOTE: When transporting or storing the
miter saw, the slide carriage should always
be locked in position. The slide carriage
lock knob is located on the rear side of the
slide carriage.
1. Lower the cutting head and push in the
lock pin (2).
2. Carry this miter saw with the build-in
carrying handle (3) and switch
handle (1).
NOTE: The blade is not provided with
this miter saw. Please use the right blade
for cutting.
Removing the Blade (Fig. 31, 32, 33, 34)
1. Unplug the saw from the outlet.
2. Allow the miter saw to rise to the
upright position.
3. Loosen the cover plate screw (2) with
a Phillips screwdriver. (Fig. 31)
4. Raise the lower blade guard (1) to the
up position.
4. Rotate the cover plate (3) to expose the
arbor bolt (4). (Fig. 32)
5. Place the blade wrench on the arbor
bolt (4).
6. The arbor lock (5) is located on the
motor, below the miter saw switch
handle. (Fig. 33)
7. Press the arbor lock (5), holding it in
firmly while turning the blade wrench.
The arbor lock (5) will engage while
turning the blade wrench. Continue
to hold the arbor lock (5) to keep it
engaged, turning the blade wrench
clockwise to loosen the arbor
bolt (4 - Fig. 32). (Fig. 33)
8. Remove the arbor bolt (4), the arbor
collar (6), the blade (7) and the
reducer
(8). Do not remove the inner
arbor collar. (Fig. 34)
NOTE: Pay attention to the pieces
removed, noting their position and
direction they face. Wipe the blade collars
clean of any sawdust before installing
a new blade. Also, the 255 mm blade
has a 25.4 mm arbor hole with a 16 mm
reducer (8) to mount onto the saw.
Changing Blades
WARNING: Do not use a blade larger
than 255 mm in diameter. To avoid injury
from an accidental start, make sure
the switch is in the OFF position and
the plug is not connected to the power
source outlet.
Let the blade reach full speed before
cutting. This will help reduce the risk
of a thrown workpiece.
12
Maintenance
Occasionally use a cloth to wipe off chips
and dust from the machine. And oil the
rotary parts once a month to extend the tool
life. Do not oil the motor.
Check the motor brushes after the first
50 hours of use for a new machine or after
a new set of brushes have been installed.
After the first check, examine them every
10 hours of use.
When the carbon is worn to 6 mm in length
or if the spring or shunt wire is burned
or damaged, replace both brushes. If
the brushes are found serviceable after
removing, reinstall them.
General Maintenance
Brush Inspection
WARNING: For your own safety, turn the
switch off and remove the plug from the
power source outlet before maintaining
or lubricating your miter saw.
Installing the Blade (Fig. 31, 32, 33, 34)
Unplug the miter saw before changing/
installing the blade.
1. Install a 255 mm blade with a 25.4
mm arbor hole with a 16 mm reducer,
making sure the rotation arrow on the
blade matches the clockwise rotation
arrow on the upper guard, and the blade
teeth are pointing downward.
2. Place the reducer (8), the blade (7) and
the arbor collar (6) in turn on the arbor.
Thread the arbor bolt (4) onto the arbor
in a counterclockwise direction. (Fig. 34)
IMPORTANT: Make sure the flats of the
blade collars are engaged with the flats
on the arbor.
3. Place the blade wrench on the arbor
bolt (4). (Fig. 34)
4. Press the arbor lock (5), holding
it in firmly while turning the blade
counterclockwise. When arbor lock (5)
engages, continue to press it in while
tightening the arbor bolt securely.
(Fig. 33)
5. Lower the blade guard (1) and rotate
the cover plate (3) back to its original
position until the slot in the cover plate
engages with the cover plate screw (2).
6. Tighten the screw (2) with a Phillips
screwdriver. (Fig. 31)
7.
Verify that the operation of the blade
guard (1) does not bind or stick. (Fig. 31)
8. Be sure the arbor lock (5) is released so
the blade turns freely. (Fig. 33)
WARNING!
To avoid injury, never use the saw
without the cover plate secure in
place. It keeps the arbor bolt from
falling out if it accidentally loosens,
and helps prevent the spinning blade
from coming off the saw.
Make sure the collars are clean and
properly arranged. Lower the blade
into the lower table and check for any
contact with the base or the miter
table by spinning the blade manually.
