5. DON’T USE IN DANGEROUS ENVIRON-
MENT. Don’t use power tools in damp or
wet locations, or expose them to rain.
Keep work area well lighted. Don’t use
tool in presence of flammable liquids or
gases.
16. REDUCE THE RISK OF UNINTENTIONAL
STARTING. Make sure switch is in off
position before plugging in.
17. USE RECOMMENDED ACCESSORIES.
Consult the owner’s manual for recom-
mended accessories. The use of improper
accessories may cause risk of injury to
persons.
6. KEEP CHILDREN AWAY. All visitors
should be kept safe distance from work
area.
18. NEVER STAND ON TOOL. Serious injury
could occur if the tool is tipped or if the
cutting tool is unintentionally contacted.
7. MAKE WORKSHOP KID PROOF with pad-
locks, master switches, or by removing
starter keys.
19. CHECK DAMAGED PARTS. Before further
use of the tool, a guard or other part that
is damaged should be carefully checked
to determine that it will operate properly
and perform its intended function - check
for alignment of moving parts, binding of
moving parts, breakage of parts, mount-
ing, and any other conditions that may
affect its operation. A guard or other part
that is damaged should be properly
repaired or replaced.
8. DON’T FORCE TOOL. It will do the job bet-
ter and safer at the rate for which it was
designed.
9. USE RIGHT TOOL. Don’t force tool or
attachment to do a job for which it was not
designed.
10. WEAR PROPER APPAREL. Do not wear
loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get
caught in moving parts. Nonslip footwear
is recommended. Wear protective hair
covering to contain long hair.
20. DIRECTION OF FEED. Feed work into a
blade or cutter against the direction of
rotation of the blade or cutter only.
11. ALWAYS USE SAFETY GLASSES. Also
use face or dust mask if cutting operation
is dusty. Everyday eyeglasses only have
impact resistant lenses, they are NOT
safety glasses.
21. NEVER LEAVE TOOL RUNNING UNAT-
TENDED. TURN POWER OFF. Don’t leave
tool until it comes to a complete stop.
22. REPLACEMENT PARTS. When servicing
use only identical replacement parts.
12. SECURE WORK. Use clamps or a vise to
hold work when practical. It’s safer than
using your hand and it frees both hands
to operate tool.
23. POLARIZED PLUGS. To reduce the risk of
electric shock, this equipment has
a
polarized plug (one blade is wider than
the other). This plug will fit in a polarized
outlet only one way. If the plug does not fit
fully in the outlet, reverse the plug. If it
still does not fit, contact a qualified elec-
trician to install the proper outlet. Do not
change the plug in any way.
13. DON’T OVERREACH. Keep proper footing
and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools
sharp and clean for best and safest perfor-
mance. Follow instructions for lubricating
and changing accessories.
15. DISCONNECT TOOLS before servicing;
when changing accessories such as
blades, bits, cutters, and the like.

VOLTAGE WARNING: Before connecting the tool to a power source (receptacle, outlet,
etc.) be sure the voltage supplied is the same as that specified on the nameplate of the tool.
A power source with voltage greater than that specified for the tool can result in SERIOUS
INJURY to the user - as well as damage to the tool. If in doubt, DO NOT PLUG IN THE
TOOL. Using a power source with voltage less than the nameplate rating is harmful to the
motor.
USE PROPER EXTENSION CORD. Make sure your extension cord is in good condition.
When using an extension cord, be sure to use one heavy enough to carry the current your
product will draw. An undersized cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size to use depending on cord length and
nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage num-
ber, the heavier the cord.

12. Be careful not to damage the arbor,
flanges (especially the installing surface)
or bolt. Damage to these parts could
result in blade breakage.
26. NEVER hold workpiece on right side of
blade with left hand or vice versa. This is
called cross-armed cutting and exposes
user to risk of SERIOUS PERSONAL
INJURY as shown in the figure. ALWAYS
use vise to secure workpiece.
13. Make sure that the turn base is properly
secured so it will not move during opera-
tion. Use the holes in the base to fasten
the saw to a stable work platform or
bench. NEVER use tool where operator
positioning would be awkward.

OPERATION
CAUTION:
•
•
•
Before use, be sure to release the handle from the
lowered position by pulling the stopper pin.
Make sure the blade is not contacting the workpiece, etc.
before the switch is turned on.
Do not apply excessive pressure on the handle when
cutting. Too much force may result in overload of the
motor and/or decreased cutting efficiency. Push down
handle with only as much force as is necessary for
smooth cutting and without significant decrease in blade
speed.
•
Gently press down the handle to perform the cut. If the
handle is pressed down with force or if lateral force is
applied, the blade will vibrate and leave a mark (saw
mark) in the workpiece and the precision of the cut will
be impaired.
001793
1. Press cutting
Secure the workpiece with the vise. Switch on the tool
without the blade making any contact and wait until the
blade attains full speed before lowering. Then gently
lower the handle to the fully lowered position to cut the
workpiece. When the cut is completed, switch off the tool
and WAIT UNTIL THE BLADE HAS COME TO A COM-
PLETE STOP before returning the blade to its fully ele-
vated position.
2. Miter cutting
Refer to the previously covered “Adjusting the miter
angle”.

001841
3. Bevel cut
Loosen the lever and tilt the saw blade to set the bevel
angle (Refer to the previously covered “Adjusting the
bevel angle”). Be sure to retighten the lever firmly to
secure the selected bevel angle safely. Secure the work-
piece with a vise. Switch on the tool without the blade
making any contact and wait until the blade attains full
speed. Then gently lower the handle to the fully lowered
position while applying pressure in parallel with the
blade. When the cut is completed, switch off the tool and
WAIT UNTIL THE BLADE HAS COME TO A COM-
PLETE STOP before returning the blade to its fully ele-
vated position.
CAUTION:
•
•
Always be sure that the blade will move down to bevel
direction during a bevel cut. Keep hands out of path of
saw blade.
During a bevel cut, it may create a condition whereby the
piece cut off will come to rest against the side of the
blade. If the blade is raised while the blade is still
rotating, this piece may be caught by the blade, causing
fragments to be scattered which is dangerous. The blade
should be raised ONLY after the blade has come to a
complete stop.
•
•
When pressing the handle down, apply pressure parallel
to the blade. If the pressure is not parallel to the blade
during a cut, the angle of the blade might be shifted and
the precision of the cut will be impaired.
Always set the sub-fence to the left position when
performing left bevel cuts.
4. Compound cutting
Compound cutting is the process in which a bevel angle
is made at the same time in which a miter angle is being
cut on a workpiece. Compound cutting can be performed
at angle shown in the table.

8. Cutting repetitive lengths
When cutting several pieces of stock to the same length,
ranging from 295 mm (11 - 5/8”) to 440 mm (17 x 1/4”),
use of the set plate (optional accessory) will facilitate
more efficient operation. Install the set plate on the
holder as shown in the figure.
Align the cutting line on your workpiece with either the
left or right side of the groove in the kerf board, and while
holding the workpiece from moving, move the set plate
flush against the end of the workpiece. Then secure the
set plate with the screw. When the set plate is not used,
loosen the screw and turn the set plate out of the way.

WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to the State of California
to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber.
Your risk from these exposures varies, depending on how often you do this
type of work. To reduce your exposure to these chemicals: work in a well
ventilated area, and work with approved safety equipment, such as those
dust masks that are specially designed to filter out microscopic particles.
MAKITA LIMITED ONE YEAR WARRANTY
Warranty Policy
Every Makita tool is thoroughly inspected and tested before leaving the factory. It is warranted to be free of
defects from workmanship and materials for the period of ONE YEAR from the date of original purchase.
Should any trouble develop during this one year period, return the COMPLETE tool, freight prepaid, to one of
Makita’s Factory or Authorized Service Centers. If inspection shows the trouble is caused by defective
workmanship or material, Makita will repair (or at our option, replace) without charge.
This Warranty does not apply where:
• repairs have been made or attempted by others:
• repairs are required because of normal wear and tear:
• the tool has been abused, misused or improperly maintained:
• alterations have been made to the tool.
IN NO EVENT SHALL MAKITA BE LIABLE FOR ANY INDIRECT, INCIDENTAL OR CONSEQUENTIAL
DAMAGES FROM THE SALE OR USE OF THE PRODUCT. THIS DISCLAIMER APPLIES BOTH DURING
AND AFTER THE TERM OF THIS WARRANTY.
MAKITA DISCLAIMS LIABILITY FOR ANY IMPLIED WARRANTIES, INCLUDING IMPLIED WARRANTIES OF
“MERCHANTABILITY” AND “FITNESS FOR A SPECIFIC PURPOSE,” AFTER THE ONE YEAR TERM OF THIS
WARRANTY.
This Warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. Some states do not allow limitation on how long an implied
warranty lasts, so the above limitation may not apply to you.
