Familiarization (Fig. A, D)
Your miter saw is not fully assembled in the carton. Refer to Assembling the Base Extensions
and Assembling the Stabilizer Bar sections for assembly instructions. Open the box and lift
the saw out by the convenient lifting handle 
Place the saw on a smooth, flat surface such as a workbench or strong table.
Examine Figure A to become familiar with the saw and its various parts. The section on
adjustments will refer to these terms and you must know what and where the parts are.

CAUTION: Pinch Hazard. To reduce the risk of injury, keep thumb underneath the handle
when pulling the handle down. The lower guard will move up as the handle is pulled
down which could cause pinching. The handle is placed close to the guard for special cuts.
Press down lightly on the operating handle 
90 degrees. Gently release the downward pressure and hold the arm allowing it to rise to its
full height. Use the head lock knob when carrying the saw from one place to another. Always
use the lifting handle 
to transport the saw or the hand indentations

Use of CUTLINE™ LED Worklight (Fig. A)

CAUTION: Do not stare into worklight. Serious eye injury could result.
nOTE: The battery must be charged and connected to the miter saw.
The CUTLINE™ LED Worklight can be turned on by the momentary switch 
automatically turn off within 20 seconds if the saw is not in use. The light is also activated
automatically every time the tool's main trigger 
To cut through an existing pencil line on a piece of wood, turn on the CUTLINE™ worklight
using the momentary switch 
 21 
(not with the main trigger), then pull down on the operating
handle 
 2 
to bring the saw blade close to the wood. The shadow of the blade will appear
on the wood. This shadow line represents the material that the blade will remove when
performing a cut. To correctly locate your cut to the pencil line, align the pencil line with the
edge of the blade's shadow. Keep in mind that you may have to adjust the miter or bevel
angles in order to match the pencil line exactly.
Your saw is equipped with a battery monitoring feature. The CUTLINE™ worklight begins
to flash when the battery is near the end of its useful charge and/or when the battery is
too hot. Charge the battery prior to continuing cutting applications. Refer to Charging
Procedure under Important Safety Instructions for All Battery Chargers for battery
charging instructions.
Miter Control (Fig. A)
The miter lock lever and miter detent latch allow you to miter your saw to 60 ° right and 50 °
left. To miter the saw, lift the miter lock handle 
move the miter arm to the angle desired on the miter scale 
pointer 
 31 
. Push down on the miter lock lever to lock the miter arm in place.
Assembling the Base Extensions (Fig. E)

WARNING: Base extensions must be assembled to both sides of the saw's base before
using the saw.
1. The extension 
should be oriented as shown in Figure E, sliding fully into the
 32 
U‑shaped supports.
2. Clamp the extension's rods against the miter saw base by inserting the extension
screw 
 63 
entirely through and the clamp.
3. Repeat steps 1 through 3 on the other side.
Bench Mounting (Fig. A)
Mounting holes 
are provided in all 4 feet to facilitate bench mounting, as shown in Figure A.
 5 
(Two different‑sized holes are provided to accommodate different sizes of screws. Use either
hole, it is not necessary to use both.) Always mount your saw firmly to a stable surface to
prevent movement. To enhance the tool's portability, it can be mounted to a piece of 1/2"
(12.7 mm) or thicker plywood which can then be clamped to your work support or moved to
other job sites and reclamped.
nOTE: If you elect to mount your saw to a piece of plywood, make sure that the mounting
screws don't protrude from the bottom of the wood. The plywood must sit flush on the work
support. When clamping the saw to any work surface, clamp only on the clamping bosses
where the mounting screw holes are located. Clamping at any other point will surely interfere
with the proper operation of the saw.

CAUTION: To prevent binding and inaccuracy, be sure the mounting surface is not
warped or otherwise uneven. If the saw rocks on the surface place a thin piece of material
under one saw foot until the saw sits firmly on the mounting surface.
Assembling the Stabilizer Bar (Fig. F)
Your saw includes one base stabilizer 
 14 
the stabilizer into the holes in the back of the unit. Move the stabilizer in or out until it contacts
the work surface. Then tighten the screws 
Changing or Installing a New Saw Blade (Fig. A, G)

WARNING: To reduce the risk of serious personal injury, turn tool off, and remove
the battery pack before transporting, making any adjustments, cleaning,
repairing, or removing/installing attachments or accessories. An accidental
start‑up can cause injury.

CAUTION:
Never depress the spindle lock button while the blade is under power or coasting.
Do not cut ferrous metal (containing iron or steel) or masonry or fiber cement product
with this miter saw.
Removing the Blade (Fig. A, G)
1. Remove battery pack 
2. Raise the arm to the upper position and raise the lower guard 
3. Depress the spindle lock button 
the lock engages.
4. Using your finger, pivot the blade bolt plate 
5. Keeping the spindle lock button depressed and blade bolt plate pushed out of the way,
use the blade wrench 
threads.) Remove the blade screw.  
6. Proceed to remove the outer clamp washer, blade adaptor and saw blade.

Miter Scale Adjustment (Fig. A, H)
Unlock the miter lock handle 
the 0 ° miter position. Do not lock the miter lock handle. Place a square against the saw's
fence and blade, as shown. (Do not touch the tips of the blade teeth with the square. To do
so will cause an inaccurate measure ment.) If the saw blade is not exactly perpendicular to
the fence 
, loosen the four miter scale screws 
 12 
miter lock handle and the scale left or right until the blade is perpendicular to the fence, as
measured with the square. Retighten the four screws. Pay no attention to the reading of the
miter pointer at this time.
Miter Pointer Adjustment (Fig. A)
Unlock the miter lock handle 
lock handle unlocked, squeeze the miter detent latch 
place as you rotate the miter arm to zero. Observe the miter pointer 
shown in Figure A. If the pointer does not indicate exactly zero, loosen the miter pointer
screw

. Place a square against the blade, ensuring the square is not on top of a tooth.
Loosen the bevel lock knob 
the 0 ° bevel adjustment screw 
is at 0 ° bevel to the table.
Bevel Pointer (Fig. J)
If the bevel pointer 
 43 
move the pointer as necessary. Ensure the 0 ° bevel is correct and the bevel pointers are set
before adjusting any other bevel angle screws.
Adjusting the Bevel Stop to 45 ° Left or Right (Fig. A, J)
To adjust the right 45 ° bevel angle, loosen the bevel lock knob 
rotate 90 ° (either clockwise or counterclockwise) and let go for the spring loaded pin to lock
in to override the 0 ° bevel stop. When the saw is fully to the right, if the bevel pointer does not
indicate exactly 45 °, turn the left 45 ° bevel adjustment screw 
until the bevel pointer indicates 45 °.
To adjust the left 45 ° bevel stop, first loosen the bevel lock knob and tilt the head to the left. If
the bevel pointer does not indicate exactly 45 °, turn the right 45 ° bevel adjustment screw 
until the bevel pointer 
Adjusting the Bevel Stop to 22.5 ° (or 33.9 °)
nOTE: Adjust the bevel angles only after performing the 0 ° bevel angle and bevel
pointer adjustment.
To set the left 22.5 ° bevel angle, flip out the left 22.5 ° bevel pawl 
lock knob 
 13 
and tilt the head fully to the left. If the bevel pointer does not indicate
exactly 22.5 °, turn the crown adjustment screw 
wrench until the bevel pointer reads 22.5 °.
To adjust the right 22.5 ° bevel angle, flip out the right 22.5 ° bevel pawl. Loosen the bevel
lock knob and pull the 0 ° bevel stop and rotate 90 degrees to override the 0 ° bevel stop.
When the saw is fully to the right, if the bevel pointer does not indicate exactly 22.5 °,
turn the crown adjustment screw contacting the pawl with a 7/16" wrench until the bevel
pointer indicates exactly 22.5 °.
