2. For portable use, place the saw on

a 19.05 mm thick piece of plywood.

Bolt the base of the miter saw

securely to the plywood using the

mounting holes on the base. Use

C-clamps to clamp this mounting

board to a stable work surface at

the worksite.

BASIC SAW OPERATION

1. Always use the clamp to hold the

work piece rmly. Two holes are

provided for the clamp.

2. Always position the workpiece

against the fence. Any piece that

is bowed or warped and cannot

be held at on the table or against

fence may trap the blade and

should not be used.

BODY AND HAND POSITION

(FIG. 24)

Never place hands near cutting area.

Keep hands outside the “No-Hands

Zone” which includes entire table and

is labeled by “No Hands” symbols.

Mounting instructions (Fig. 23)

1. For stationary use, place the saw

in the desired location, directly on a

workbench where there is room for

handling and proper support of the

workpiece. The base of the saw has

four mounting holes. Bolt the base

of the miter saw (1) to the work

surface (5), using the fastening

method as shown in Fig. 23.

Operating the Tool

WARNING! Never connect the plug

to the power source outlet until

all installations and adjustments

are completed and you have read

and understood the safety and

operational instructions.

WARNING! To avoid injury from

materials being thrown, unplug saw

to avoid accidental starting, and then

remove small materials.

2. To cut wide boards up to 305 mm,

the slide carriage lock knob (1)

must be loosened to allow the

cutting head to slide freely.

QUICK-CAM LOCKING LEVER

OPERATION (FIG. 28)

If miter angles required are NOT one of

the nine positive stops, the miter table

can be locked at any angle between

these positive stops by using the quick-

cam locking lever.

1. Unlock the miter table by lifting up

on the quick-cam locking lever (1).

place at one of the nine positive

stops.

TURNING SAW ON (FIG. 25)

Squeeze the trigger switch (1) to turn

the miter saw ON. Release the trigger

switch to turn the saw OFF.

NOTE: Make the ON/OFF switch

childproof. Insert a padlock, or chain

with padlock, through the hole (2)

in the trigger and lock the tool’s

switch, preventing children and other

unqualied users from turning the

machine on.

SLIDING FENCE (FIG. 26)

1. Unlock the fence locking lever (1)

by pushing it toward the rear of the

machine.

2. Extend the fence (2) by sliding it

out. Lock the fence locking lever (1)

by pulling it in toward the fence.

NOTE: When transporting the saw,

always secure the sliding fence in

the collapsed position and locking it.

SLIDE CARRIAGE SYSTEM (FIG. 27)

1. For chop cutting operations on

small workpieces, slide the cutting

head assembly completely toward

the rear of the unit and tighten the

slide carriage lock knob (1).

WARNING! The sliding fence must

be extended when making any bevel

cut. Failure to extend the sliding

fence will not allow enough space

for the blade to pass through which

could result in serious injury. At

extreme miter or bevel angles the

saw blade may also contact the

fence.

WARNING! To reduce the risk of

injury, return slide carriage to the

full rear position after each crosscut

operation.

4. Once the desired miter angle is

achieved, press down on the quick-

cam locking lever (1) to secure the

table into position.

5. If the desired miter angle is NOT

one of the nine positive stops noted

above, simply lock the table at the

desired angle by pressing down on

the quick-cam locking lever (1).

6. Turn the laser guide on and position

the workpiece on the table for pre-

alignment of your cut.

BEVEL CUT (FIG. 30)

1. When a bevel cut is required,

loosen the bevel lock knob (1) by

turning it clockwise.

2. Tilt the cutting head to the desired

angle, as shown on the bevel

scale (2).

3. The blade can be positioned at

any angle, from a 90° straight cut

(0° on the scale) to a 45°. Tighten

the bevel lock knob (1) to lock the

cutting head in position. Positive

stops are provided at 0° and 45°.

4. Turn the laser guide on and position

the workpiece on the table for pre-

alignment of your cut.

WARNING! The sliding fence must

be extended when making any bevel

cut. Failure to extend the sliding

fence will not allow enough space

for the blade to pass through which

could result in serious injury. At

extreme miter or bevel angles the

saw blade may also contact the

fence.

COMPOUND CUT (FIG. 30, 31)

A compound cut is the combination of

a miter and a bevel cut simultaneously.

1. Extending the fence by sliding it out

to the required location or remove

the left sliding fence if necessary.

See “SLIDING FENCE.”

2. Set the desired bevel angle using

the bevel lock knob (1). (Fig. 30)

3. Set the desired miter angle and lock

into position. See “MITER CUT.”

BASE MOLDING CUT (FIG. 32)

Base moldings and many other

moldings can be cut on a compound

miter saw. The setup of the saw

depends on molding characteristics

and application, as shown. Perform

practice cuts on scrap material to

achieve best results:

1. Always make sure moldings rest

rmly against fence and table. Use

hold-down clamp, crown molding

vise or C-clamps, whenever

possible, and place tape on the

area being clamped to avoid marks.

2. Reduce splintering by taping the cut

area prior to making the cut. Mark

the cut line directly on the tape.

3. Splintering typically happens due to

an incorrect blade application and

thinness of the material.

NOTE: Always perform a dry

run cut so you can determine if

the operation being attempted is

possible before power is applied to

the saw.

INSTALLING THE BLADE

(FIG. 35, 36, 37)

1. Unplug the saw from the outlet.

2. Raise the miter saw to the upright

position. Slide the cutting head

assembly completely toward the

rear of the unit and tighten the

sliding carriage lock knob.

3. Raise the lower blade guard (1) to

the uppermost position.

Changing Blades

WARNING! To avoid injury from

accidental starting, always turn the

switch off and remove the power

plug from the power source before

changing the blades. Use correctly

sharped saw blades. Observe the

maximum speed and tooth type

marked on the saw blade. Blade

replacement procedure including

the method for repositioning that

this must be carried out correctly.

Do not use a saw blade which is

not recommended in this owner’s

manual.

CROWN MOLDING CUT (FIG. 33, 34)

Your compound miter saw is suited

for the difcult task of cutting crown

molding. To t properly, crown molding

must be compound-mitered with

extreme accuracy. The two surfaces

on a piece of crown molding that t

at 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 ts at against

the ceiling) of 52°and a bottom rear

angle (the section that ts at 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 at 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.

4. While holding the lower blade

guard, loosen the cover plate

screw (2) with a Phillips screwdriver.

5. Rotate the cover plate (3) to expose

the arbor bolt (4).

6. Place the blade end wrench over

the arbor bolt (4).

7. Locate the arbor lock (5) on the

motor.

8. Press the arbor lock (5), holding

it in rmly while turning the blade

clockwise. The arbor lock (5) will

then engage and lock the arbor.

Continue to hold the arbor lock (5),

while turning the wrench clockwise

to loosen the arbor bolt (4).

9. Remove the arbor bolt (4), outer

blade collar (6), the blade (7) and

the reducer (8). Do not remove the

inner blade collar.

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.

INSTALLING THE BLADE

(FIG. 35, 36, 37)

1. Install a 216 mm blade with a

25.4 mm arbor 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 outer

blade collar (6) against the blade

and on the arbor. Thread the

arbor bolt (4) on the arbor in a

counterclockwise direction.

WARNING! Un-plug the miter saw

before changing/installing the blade.

IMPORTANT: Make sure the ats of

the blade collars are engaged with

the ats on the arbor shaft. Also, the

at side of the blade collar must be

placed against the blade.

3. Place the blade wrench on the arbor

bolt (4).

4. Press the arbor lock (5), holding it in

rmly while turning the blade

counterclockwise. When it engages,

continue to press the arbor lock (5)

in, while tightening the arbor bolt (4)

securely.

5. Rotate the cover plate (3) back to its

original position until the slot in the

cover plate engages with the cover

plate screw (2). While holding the

lower blade guard (1), tighten the

NOTE: The lower blade guard (1)

must be raised to the upright

position to access the cover plate

screw.

6. Lower the lower blade guard (1) and

verify the operation of the guard

does not bind or stick.

7. Be sure the arbor lock (5) is

released so the blade turns freely .

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.

Maintenance

GENERAL 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.

BRUSHE INSPECTION (FIG. 38)

Check the motor brushes after the rst

50 hours of use for a new machine or

after a new set of brushes have been

installed. After the rst 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.

To inspect or replace brushes, rst

unplug the saw. Then remove the

black plastic cap (1) on the side of

the motor (2). Carefully remove the

spring-loaded cap. Then pull out the

brush and replace. Replace for the

other side. To reassemble, reverse the

procedure. The ears on the metal end

of the assembly go in the same hole

the carbon part ts into. Tighten the

cap snugly, but do not overtighten.

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.

WARNING! Always disconnect the

plug from the power source before

inspecting the brushes.
