GENERAL SAFETY
PRECAUTIONS
(For
All
Tools)
1.
KNOW YOUR POWER TOOL. Read the owner's manual carefully. Learn the
tools applications and limitations, as well as the specific potential hazards
peculiar to
it.
2.
KEEP GUARDS IN PLACE and
in
working order.
3.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removed from tool before turning
it
on.
4.
KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
5.
DON'T USE IN DANGEROUS ENVIRONMENT. 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.
6.
KEEP CHILDREN AWAY. All visitors should be kept safe distance from work
area.
7.
MAKE WORKSHOP KID
PROOF
with
padlocks, master switches, or by
removing starter keys.
8.
DON'T FORCE TOOL.
It
will do the job better 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.
IO.
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.
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.
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.
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 performance. Follow instructions for lubricating and changing acces-
sories.

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

IO.
Be sure that the blade does not contact the base
in
the lowest position.
11.
Hold the handle firmly. Be aware that the saw moves up or down slightly
during start-up and stopping.
12.
Do
not perform any operation freehand. The workpiece must be secured
firmly with the vise during all operations.
13.
Keep hands out of path of saw blade, Avoid contact with any coasting blade.
It
can still cause severe injury.
14.
Never reach around saw blade.
15.
Make sure the blade is not contacting the workpiece before the switch is
turned on.
16.
Before using the tool on an actual workpiece, let
it
run for a while. Watch
for vibration or wobbling that could indicate poor installation or a poorly
balanced blade.
17. Wait until the blade attains
full
speed before cutting.
18. Stop operation immediately
if
you notice anything abnormal.
19.
DO
not attempt to lock the trigger in the on position.
20.
Shut off power and wait for saw blade to stop before servicing or adjusting

21.
Be alert at all times, especially during repetitive, monotonous operations.
Don't be lulled into a false sense of security. Blades are extremely unforgiving.
22.
Turn off tool and wait for saw blade to stop before moving workpiece or
changing settings.
23. Always use accessories recommended
in
this manual. Use of improper
accessories such as abrasive wheels may cause an injury.

disconnect
it
from the receptacle. Keep
cord away from heat, oil, water and sharp edges.
25. Never attempt to cut workpieces less than
14
Gauge
(0.08")
thick except
pipe or workpieces which cannot be secured firmly with the vise. The piece
cut off may be caught by the blade, causing dangerous scattering of chips
and/or damage to the carbide-tips. Possible serious injury may result.

installing
saw
blade
CAUTION:
.Always be sure that the tool is switched off and unplugged before removing or installing
the blade.
.When mounting the blade, make sure that the direction
of
the arrow on the surface of
the blade matches the direction of the arrow on the blade case.
.Use only the Makita socket wrench provided to install or remove the blade. Failure to do
so
may result in overtightening or insufficient tightening of the hex bolt. This could cause
serious injury to operator or others in the general vicinity of the tool.
.Do
not touch the blade immediately after operation; it may be extremely hot and could
burn your skin.
To
remove the blade, loosen the hex bolt
holding the center cover with the socket
wrench. Raise the safety cover (safety
guard) and center cover.

To install the blade, mount the inner flange,
saw blade, outer flange and hex bolt onto
the spindle in that order. Tighten the hex
bolt by turning clockwise while pressing the
shaft lock. Return the safety cover and
center cover to the original position. Then
tighten the hex bolt clockwise to secure the

Setting for desired cutting angle
CAUTION:
Always tighten the hex bolt securely after changing the cutting angle.
To change the cutting angle, loosen the
lever. Move the vise stop
so
that the indi-
cator
will
point to the desired graduation.
Then tighten the lever to secure the vise
stop.

Securing workpieces
CAUTION:
Always set the vise nut to the right fully when securing the workpiece. Failure to do
so
may result in insufficient securing of the workpiece. This could cause the workpiece to be
ejected or cause damage to the blade.
By
turning the vise handle counterclock-
wise and then flipping the vise nut to the
left, the vise is released from the shaft
threads and can be moved rapidly in and
out. To grip workpieces, push the vise
handle until the vise plate contacts the
workpiece. Flip the vise nut to the right and
then turn the vise handle clockwise to
securely retain the workpiece.

Cutting operation
CAUTION:
*Never attempt to cut workpieces less than
14
gauge
(0.08”)
thick except pipe or work-
pieces which cannot be secured firmly
with
the vise. The piece cut off may be caught by
the blade, causing dangerous scattering of chips and/or damage to the carbide-tips.
Pos-
sible serious injury may result.
*Do not apply excessive pressure on the handle when cutting. Too much pressure
may result in overload of the motor, decreased cutting efficiency and/or damage to the
carbide-tips or blade itself.
*TOO little pressure on the handle may result in more sparks and premature blade wear

not touch the blade, workpiece or cutting chips immediately after operation; they may

the tool immediately. Replace cracked or damaged blade with a new one.
Hold the handle firmly. Switch on the tool and wait until the blade attains full speed. Then
lower the handle gently to bring the blade close to the workpiece. When the blade makes
contact, ease into the cut gently at first, then gradually add pressure as the cutting posi-
tion steadies. Your pressure on the handle should be adjusted to produce the minimum
amount
of
sparks.
When the cut is completed, switch off the tool and WAIT UNTIL THE BLADE HAS COME
TO A COMPLETE STOP before returning the handle to the fully elevated position.
If
the
handle is raised while the blade is still rotating, the piece cut off may be caught by the
blade, causing dangerous scattering
of
chips. When cutting only part
of
the way into
a
workpiece, raise the handle while the blade is rotating. Switching off during the cut may
cause damage to the carbide-tips as they contact the workpiece.
Dust
collection
CAUTION:
Do
not touch any part of the dust box except its handle immediately after operation; it
may be extremely hot and could burn your skin.
This tool is equipped with the dust box to
collect dust and cut chips. When the dust
box is full, hold the handle of the dust box
and raise it slightly. Then pull the dust box
out
of
the
tool
base.
Empty the dust box of
its contents.

Carrying the tool
Fold down the tool head to the position
where you can attach the chain to the hook
on the handle. Grasp the carrying grip
when carrying the tool.

MAINTENANCE
CAUTION:
Always be sure that the tool is switched off and unplugged before attempting to perform
inspection or maintenance.
Replacing saw blade
Continuing to use
a
dull and worn blade may cause motor overload and decreased cutting
efficiency. Replace with
a
new blade as soon as it is no longer effective.
Replacing carbon brushes
Remove and check the carbon brushes
regularly. Replace when they wear down
to
the limit mark. Keep the carbon brushes
clean and free to slip in the holders. Both
carbon brushes should be replaced at
the same time. Use only identical carbon
brushes.
Use
a
screwdriver to remove the brush
holder caps. Take out the worn carbon
brushes, insert the new ones and secure
the brush holder caps.
