1. KEEPWORK AREA CLEAN. Clutteredareas and benches invite injuries.
2. CONSIDERWORK AREA ENVIRONMENT. Don’t use power tools in damp or
wet locations. Keep work area well lit. Don’t expose power tools to rain.
Don’t usetool in presence of flammableliquids or gases.
3. KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don’t let visitors contact tool or extension cord.
4. STORE IDLETOOLS.When not in use,tools should bestored in dry, andhigh
or locked-upplace
- out of reachof children.
DON’T FORCETOOL.
It will do the job better and safer at the ratefor which
itwas intended.
USE RIGHT TOOL. Don’t force small tool or attachment to
do the job of a
heavy-dutytool. Don’t usetool for purpose not intended; for example, don’t
use circular saw for cutting tree limbs or logs.
DRESS PROPERLY. Don’t wear looseclothing or jewelry.They can becaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors.Wear protective hair covering tocontain long hair.
USE SAFETY GLASSES. Also use face or dust mask if cutting operation is
dusty.
DON’T ABUSE CORD. Never carry tool by cord or yank
it todisconnect from
receptacle. Keep cord from heat,oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold work. It’s safer than using
your handand itfrees both handsto operate tool.
DON’T OVERREACH. Keep properfooting and balanceat
all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing acces-
sories. Inspect tool cords periodically and if damaged, have repaired by
authorizedservice facility. Inspectextension cords periodically and replace
if damaged. Keep handlesdry, clean, and free from oil and grease.

17. OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only
extensioncords intendedfor useoutdoors and
so marked.
18. STAY ALERT. Watch what you are doing, use common sense. Don’t
operatetool when you are tired.
19. CHECK DAMAGED PARTS. Beforefurther 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 intendedfunction. Check for alignment of
movingparts,bindingof moving parts,breakageof parts,mounting,and any
other conditions that may affect its operation.
A guard or other part that is
damaged should be properly repairedor replacedby an authorized service
center unless otherwise indicated elsewhere in this instruction manual.
Have defective switches replaced by an authorized service center. Don’t
usetool if the switch does not turn iton and
off.
20. GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators,ranges,refrigerator enclosures.
21. REPLACEMENTPARTS.When servicing,useonly identicalreplacementparts.
22. POLARIZED PLUGS.To reducethe riskof electric shock,this equipmenthas
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,
reversethe plug.If it still does notfit, contact aqualified electrician to install
the proper outlet. Do not changethe plug
in any way.

VOLTAGE WARNING: Beforeconnecting the tool toa power source (receptacle,
outlet, etc.) be sure the voltage supplied
is the same as that specified on the
nameplateof 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 nameplaterating isharmfulto the motor.

Installing Makita jig saw blade
CAUTION
:
Always be sure that the tool is switched off and unplugged before installingor removing
the blade.
Use the hex wrench to loosenthe bolt,
With the blade teeth facing forward, insert
the blade into the blade holder
as far as
it will go.
Make sure that the back edge of the blade
fits into the roller and tighten the bolt
securely with the hex wrench.
CAUTION
:
Use a lubricant or cutting oil between the bladeand roller when cutting iron or composi-
tion board, etc. Failureto do
so will shorten the service life of your blade and roller.

Installing universal shank jig saw blade
CAUTION
:
Always be sure that the tool is switched off and unplugged before installing or removing
the blade.
If the universal blade clamp
is used, you
can use blades of other makes which have
a universal shank like the one shown in
the figure, with
a blade width of 6.35 mm
( 1 /4").
Insert the blade into the blade holder as far
as it will go. Make sure that the end of the
blade shank reaches the bottom of the
inner
slit and tighten the bolt securely with
the hex wrench.
Straight line or ot-ita1 cuttingaction
Conventional jig saws cut with
a straight
line action, that
is, the blade moves only
up and down in
a straight line. Your saw
also cuts in this manner but, for softer
workpiece, an orbital cutting action can
be selected. Soft workpiece, like wood and
plastic permit deep penetration of indi-
vidual saw teeth. The orbital action thrusts
the blade forward on the cutting stroke
and greatly increases cutting speed over
conventional jig saws. Harder workpiece
like metal should be cut using the straight
line cutting action or
a very low orbital
setting. To select straight line or orbital
cutting, adjust the number on the saw.

sure on the trigger. To start the tool,
simply pull
the trigger. Release the trigger
to stop. For continuous operation, pull the
trigger and then push in the lock button.
To stop the tool from the locked position,
pull the trigger fully, then release
it. A
speed control screw is provided so that
maximum tool speed can be limited (vari-
able). Turn the speed control screw clock-
wise for higher speed, and counterclock-
wise for lower speed.
CAUTION
:
Before plugging in the tool, always check to see that the trigger switch actuates properly
and returns to the "OFF" position when released.
Operation
Turn the tool on and wait until the blade
attains full speed. Then rest the base
flat
on the workpiece and gently move the tool
forward along the previously marked cut-
ting line. When cutting curves, advance the
tool very slowly.
CAUTION
:
Failure to holdthe tool base flush with the workpiece may cause bladebreakage.

Bevel cutting
With the base tilted, vou can make bevel
.,
cuts at any angle between 0" and 45" (left
or right).
Loosen the bolt on the back of the base
with the hex wrench, and slide the base
backwards. Tilt the base to the desired
angle. The edge
of the housing indicates
the bevel angle. Then check for contact
between the back edge
of the blade and the
roller.
Now tighten the bolt securely on the back
of the base.
Front flush cuts
Loosen the bolt on the back of the base
with the hex wrench, then slide the base
backwards. Check the contact between the
back edge of the blade and the roller, then
secure the bolt.

Plungecutting
Starting
a cut at other than the edge of the
workpiece without first drilling a starting
hole requires
a "plunge cut". This can be
accomplished by tipping the tool forward
until the front end
of the base rests against
the workpiece. Switch the tool on and
lower the back end of the tool slowly,
gradually allowing the blade to saw through
the workpiece until the base
is able to sit
flat on the workpiece. You may then pro-
ceed forward with the cut in
a normal
manner.
If using
a drill for a starting hole, bore a
hole over 12 mm (1/2") in diameter. Then
insert the blade in
it and proceed.
Finishing edges
To trim edges or make dimensional adjust-
ments, run the blade lightly along the cut
edges.
For smoother cuttingof plywoods or other
materials with easily splintered surfaces,
transparent tape may be used over your
cutting line.
Using guide rule (Rip fence)
(optional accessory)
When cutting widths
of under 150" 6")
repeatedly, use of the guide rule will
assure fast, clean, straight cuts.

To attachthe guide rule (ripfence), use the
hex wrench to loosen the bolt on the base
in front, slip in
the guide rule and secure
the bolt.
Using
circular guide
(optional
accessory)
Use of the circular guide insures clean,
smooth cutting
of circles (radius; under
200 mm; 7-7/8") and arcs.
To attach the circular guide, use the pin,
inserting
it in the center hole (arrow) and
secure
it with the threaded knob. Then
slide the base of the tool forwards. The
circular guide attaches to the base of the
tool in the same manner
as the guide rule
Fli pin into
