GENERAL SAFETY RULES USA002-2
(For All Tools)
WARNING:
Read and understand all instructions. Failure to follow all
instructions listed below, may result in electric shock, fire and/or
serious personal injury.
SAVE THESE INSTRUCTIONS
Work Area
1. Keep your work area clean and well lit.
Cluttered benches and dark areas invite acci-
dents.
2. Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power
tools create sparks which may ignite the dust
or fumes.
3. Keep bystanders, children, and visitors
away while operating a power tool. Distrac-
tions can cause you to lose control.
Electrical Safety
4. Double insulated tools are equipped with
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 a polarized outlet. Do not
change the plug in any way. Double insula-
tion eliminates the need for the three wire
grounded power cord and grounded power
supply system.

5. Avoid body contact with grounded sur-
faces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of
electric shock if your body is grounded.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
7. Do not abuse the cord. Never use the cord
to carry the tools or pull the plug from an
outlet. Keep cord away from heat, oil,
sharp edges or moving parts. Replace
damaged cords immediately. Damaged
cords increase the risk of electric shock.
8. When operating a power tool outside, use
an outdoor extension cord marked “W-A”
or “W”. These cords are rated for outdoor
use and reduce the risk of electric shock.
Personal Safety
9. Stay alert, watch what you are doing and
use common sense when operating a
power tool. Do not use tool while tired or
under the influence of drugs, alcohol, or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
10. Dress properly. Do not wear loose cloth-
ing or jewelry. Contain long hair. Keep
your hair, clothing, and gloves away from
moving parts. Loose clothes, jewelry, or long
hair can be caught in moving parts.
11. Avoid accidental starting. Be sure switch
is off before plugging in. Carrying tools with
your finger on the switch or plugging in tools
that have the switch on invites accidents.
12. Remove adjusting keys or wrenches
before turning the tool on. A wrench or a
key that is left attached to a rotating part of
the tool may result in personal injury.
13. Do not overreach. Keep proper footing
and balance at all times. Proper footing and
balance enables better control of the tool in
unexpected situations.
14. Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety
shoes, hard hat, or hearing protection must
be used for appropriate conditions. Ordinary
eye or sun glasses are NOT eye protection.
Tool Use and Care
15. Use clamps or other practical way to
secure and support the workpiece to a
stable platform. Holding the work by hand or
against your body is unstable and may lead
to loss of control.
16. Do not force tool. Use the correct tool for
your application. The correct tool will do the
job better and safer at the rate for which it is
designed.
17. Do not use tool if switch does not turn it
on or off. Any tool that cannot be controlled
with the switch is dangerous and must be
repaired.
18. Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing the tool.
Such preventive safety measures reduce the
risk of starting the tool accidentally.
19. Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
20. Maintain tools with care. Keep cutting
tools sharp and clean. Properly maintained
tools with sharp cutting edges are less likely
to bind and are easier to control.
21. Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool ser-
viced before using. Many accidents are
caused by poorly maintained tools.
22. Use only accessories that are recom-
mended by the manufacturer for your
model. Accessories that may be suitable for
one tool, may become hazardous when used
on another tool.

SERVICE
23. Tool service must be performed only by
qualified repair personnel. Service or main-
tenance performed by unqualified personnel
could result in a risk of injury.
24. When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance instructions may create a risk of
electric shock or injury.
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.
SPECIFIC SAFETY RULES USB065-1
DO NOT let comfort or familiarity with product (gained from
repeated use) replace strict adherence to jig saw safety rules. If
you use this tool unsafely or incorrectly, you can suffer serious
personal injury.
1. Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tools may contact hidden wiring or
its own cord. Contact with a “live”wire will
make exposed metal parts of the tool “live”
and shock the operator.
2. Always use safety glasses or goggles.
Ordinary eye or sun glasses are NOT
safety glasses.
3. Avoid cutting nails. Inspect workpiece for
any nails and remove them before opera-
tion.
4. Do not cut hollow pipe.
5. Do not cut oversize workpiece.
6. Check for the proper clearance beyond
the workpiece before cutting so that the
blade will not strike the floor, workbench,
etc.
7. Hold the tool firmly.

FUNCTIONAL
DESCRIPTION CAUTION:
•Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Switch action
CAUTION:
•Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the “OFF”
position when released.
•Switch can be locked in “ON”position for ease of
operator comfort during extended use. Apply caution
when locking tool in “ON”position and maintain firm
grasp on tool.
To start the tool, simply pull the switch trigger. Release the
switch trigger to stop.
For continuous operation, pull the switch trigger and then
push in the lock button.
To stop the tool from the locked position, pull the switch trig-
ger fully, then release it.
Speed adjusting dial
The tool speed can be infinitely adjusted between 500 and
3,100 strokes per minute by turning the adjusting dial. Higher
speed is obtained when the dial is turned in the direction of
number 6; lower speed is obtained when it is turned in the
direction of number 1.
Refer to the table to select the proper speed for the work-
piece to be cut. However, the appropriate speed may differ
with the type or thickness of the workpiece. In general, higher
speeds will allow you to cut workpieces faster but the service
life of the blade will be reduced.

OPERATION CAUTION:
•Always hold the base flush with the workpiece. Failure to
do so may cause blade breakage, resulting in a serious
injury.
•Advance the tool very slowly when cutting curves or
scrolling. Forcing the tool may cause a slanted cutting
surface and blade breakage.
Turn the tool on without the blade making any contact 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 cutting line.
Bevel cutting
CAUTION:
•Always be sure that the tool is switched off and
unplugged before tilting the base.
•Raise the dust cover all the way before making bevel
cuts.
With the base tilted, you 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.
Move the base so that the bolt is positioned in the center of
the cross-shaped slot in the base.

Tilt the base until the desired bevel angle is obtained. The
edge of the motor housing indicates the bevel angle by grad-
uations. Then tighten the bolt to secure the base.
Front flush cuts
Loosen the bolt on the back of the base with the hex wrench
and slide the base all the way back. Then tighten the bolt to
secure the base.
Cutouts
Cutouts can be made with either of two methods A or B.
A) Boring a starting hole
For internal cutouts without a lead-in cut from an edge,
pre-drill a starting hole 12 mm (1/2”) or more in diameter.
Insert the blade into this hole to start your cut.
B) Plunge cutting
You need not bore a starting hole or make a lead-in cut if
you carefully do as follows.
(1) Tilt the tool up on the front edge of the base with the
blade point positioned just above the workpiece sur-
face.
(2) Apply pressure to the tool so that the front edge of
the base will not move when you switch on the tool
and gently lower the back end of the tool slowly.
(3) As the blade pierces the workpiece, slowly lower the
base of the tool down onto the workpiece surface.
