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 accidents.
2. Do not operate power tools in explosive atmo-
spheres, 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. Distractions 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 electrician 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 surfaces
such as pipes, radiators, ranges and refrigera-
tors. 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 inat-
tention while operating power tools may result in
serious personal injury.
10. Dress properly. Do not wear loose clothing 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
2
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. Hold-
ing 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 serviced before using. Many acci-
dents are caused by poorly maintained tools.
22. Use only accessories that are recommended 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 maintenance per-
formed 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 unau-
thorized 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 number, 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. Con-
tact 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 operation.
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.
3
7. Hold the tool firmly.
8. Make sure the blade is not contacting the workpiece before the switch is turned on.
9. Keep hands away from moving parts.
10. Do not leave the tool running. Operate the tool
only when hand-held.
11. Always switch off and wait for the blade to come
to a complete stop before removing the blade
from the workpiece.
12. Do not touch the blade or the workpiece immediately after operation; they may be extremely hot
and could burn your skin.
13. Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation
and skin contact. Follow material supplier safety
data.

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 surface.
(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.
(4) Complete the cut in the normal manner.
Finishing edges
001920
To trim edges or make dimensional adjustments, run the
blade lightly along the cut edges.
Metal cutting
Always use a suitable coolant (cutting oil) when cutting
metal. Failure to do so will cause significant blade wear.
The underside of the workpiece can be greased instead
of using a coolant.
Rip fence set (optional accessory)
CAUTION:
• Always be sure that the tool is switched off and
unplugged before installing or removing
accessories.
1. Straight cuts
