DRESS PROPERLY. Don't wear looseclothingorjewelry. They can becaught
in moving parts. Rubber gloves and non-skid footwear are recommended
whenworking outdoors. Wear protective haircoveringtocontainlonghair.
USE SAFETY GLASSES. Also use face or dust mask if cutting operation
is dusty.
DON'T ABUSE CORD. Never carry tool bycordor yank
it todisconnectfrom
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 hand and
it frees both hands to operate tool.

authorized service facility. Inspectextension cords periodically and replace
if damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECTTOOLS. When not
in use, beforeservicing, and whenchang-
ing accessories, such as blades, bits, cutters.

14. REMOVEADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjustingwrenches are removed from tool before
turn-
ing it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry plugged-intool withfinger

16. OUTDOOR USEEXTENSIONCORDS. Whentoolisusedoutdoors, useonly
extension cords intended for use outdoors and
so marked.
17. STAY ALERT. Watch what you are doing, use common sense. Don't oper-
ate tool when you are tired.
18. CHECK DAMAGEDPARTS. Before further use of the tool, a guard or other
part that is damaged should be carefully checkedtodetermine that
it will
operate properly and perform its intended function. Check for alignment
of movingparts, bindingof movingparts, breakageof parts, mounting, and
any other conditions that may affect its operation. A guard or other part
that
is damaged should be properly repaired or replaced by an authorized
servicecenter unlessotherwise indicatedelsewhere
in this instruction manu-
al. Have defective switches replaced by authorized service center. Don't
use tool
if switch does not turn it on and off.
19. GUARDAGAINST ELECTRIC SHOCK. Preventbodycontact withgrounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
20. REPLACEMENT PARTS. When servicing, use only identical replacement
parts.
VOLTAGE WARNING: Before connectingthe tooltoa 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 tothe 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.

HOW TO USE
MountingMakita jig saw blade
First, use the hex wrench to remove the
bolt which secures the blade clamp to the
blade holder shaft. With the blade teeth
facing forward, place the shank of the
blade over the flat side of the blade holder
shaft. Then place the blade clampover the
other side of the blade shank. Secure this
assembly together with bolt. Make sure
that the bolt passes through the larger hole
inthe blade shank.
Mountinguniversal shank jig saw blade
1. Ifthe universalblade clamp is used, you
can use blades of other makes which
have
a universal shank like the one
shown on
Fig. 2, with a blade width of
6.35 mm (1/4").
2. Remove the blade clamp usingthe hex
wrench. Then loosen the bolt on the
universal blade clamp, and fit the uni-
versal shank blade onto spring pin inside
the universalblade clamp. (Fig.
3).

the blade holder (blade inplace) so that
the spring pin fits into the hole on the
blade holder. Tighten the bolt securely
with the hex wrench (Fig.
4).
Using roller
With the hex wrench, loosen the bolt
which holds the base and retainer. Slide
the retainer
so that the roller contacts the
blade, thentightenthe bolt. However,when
the blade you use does not have
a straight
back, slide the retainer back
so that the
roller will notcontact
the blade.

Switchaction
Tool speed is increased by increasing pres-
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, pullthe
trigger fully, then release
it. A speed con-
trol screw
is provided so that maximum
tool speed can be limited (variable).Turn
the speed control screw clockwise for
higher speed, and counterclockwise for
lower speed.

CAUTION :
Before plugging in the tool, always check to see that the trigger switch actuatesproperly
and returnsto the
"OFF" positionwhen released.
Operation
Turn the tool on before contacting the
workpiece. Then rest the base flat on the
workpiece and gently move the tool for-
ward along the previously marked cutting
line.
Plungecutting
.Starting
a cut at other than the edge of
the workpiece without first drilling
a
startingholerequires 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 wood until the base
is able to sit flat on the workpiece. You
may then proceedforward with the cut in
a normalmanner.
0 If using a drill for a starting hole, bore
a hole over 12 mm (1/2") in diameter.
Then insertthe blade in
it and proceed.

Front flush cuts
Loosen the bolt on the back of the base
with the hex wrench, then slide the base
backwards. Check the contactbetween the
back edge of the blade and support roller,
thensecure the bolt.
Bevel cutting
1. Withthe base tilted, you can make bevel
cuts
at any angle between 0' and 45'
(leftto right).
2. Loosen the bolt onthe back of the base
with the hex wrench. Tilt the base to
the desired angle. The edge
of the hous-
ing indicates the bevel angle. (Fig.
11).
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.

Finishing edges
To trim edges or make dimensionaladjust-
ments, run the blade lightly along the cut
edges.
For smoother cutting of plywoodsor other
materials with easily splintered surfaces,
the wood may be coated or transparent
tape used over your cutting line.

Usingguide rule (Rip fence)
1. When cutting widths of under 150 mm
(6") repeatedly, use of the guide rule
will assure fast, clean cuts.

2. To attach the guide rule(ripfence), use
the hex wrench to loosen the screw on
the under side of the base in front, slip
inthe guide ruleand secure the screw.

Using circular guide
1. Use of the circular guide insures clean,
smooth cutting
of circles (radius;under
200 mm; 7-7/8") and arcs.

2. When attaching the circular guide, use
the pin, inserting
it in the center hole
(arrow)and secure
it with the threaded
knob. The circular guide attaches tothe
base of the tool in the same manner
as
the guide rule (ripfence).
