GENERALSAFETY RULES
(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
READ ALL 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 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.
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 insulation [] 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 refrigerators. There is an increased risk of electric shock if your body is
grounded.
6. Don't 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 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.
2

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 switches 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.
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.
1"/. 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.
lg. 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 misalignmsnt 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 accidents are caused by poorly main-
tained 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 performed by unqualified personnel could result in a risk of
injury.
24. When servicing a tool, use only identical replacement parts. Follow instruc-
tions 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.

Specific Safety Rules
1. Hold tool by insulated gdpping surfaces when performing an operation where
the cutting tool may contact hidden wiring or its own cord. Contact with
a"live" wire will also make exposed metal parts of the tool "live" and shock
the operator.
2. Avoid cutting nails. Inspect workplace for any nails and remove them before
operation.
3. Do not cut oversize workpiece.
4. Check for the proper clearance beyond the workpiece before cutting so that
the blade will not strike the floor, workbench, etc.
5, Hold the tool firmly.
6, Make sure the blade is not contacting the workplace before the switch is
turned on.
7. Keep hands away from moving parts.
8. Do not leave the tool running. Operate the tool only when hand-held.
9. Always switch off and wait for the blade to come to a complete stop before
removing the blade from the workpiece,
10. Do not touch the blade or the workpiece immediately after operation; they
may be extremely hot and could burn your skin,

FUNCTIONAL DESCRIPTION
Ad]. ng =11oo
When the blade loses its cutting efficiency
in one place along its cutting edge, reposi-
tion the shoe to unitize a shaqo, unused
portion of its cutting edge. This will help to
lengthen the life of the blade. To reposition
the shoe, loosen the lever and slide the
shoe forward or back to the desired posi-
tion. Then tighten the lever to firmly secure
the shoe.

ASSEMBLY
Installing or removing the saw blade
CAUTION:
•Always be sure that the tool is switched off and unplugged before installing or removing
the blade.
oAIways clean out all chips or foreign matter adhering to the blade, blade clamp and/or
slider. Failure to do so may cause insufficient tightening of the blade, resulting in a seri-
ous injury.
For JR3030
To install the blade, loosen the screw on
the blade clamp with the hex wrench 4 pro-
vided. Insert the blade between the blade
clamp and the slider so that the pin on the
slider fits into the hole in the blade shank. If
the pin cannot easily fit into the hole,
remove the hex wrench from the screw
and then try again. After the pin fits proper-
ly into the hole, tighten the screw securely
while making sure that the blade cannot be
extracted even though you try to pull it out.
CAUTION:
If you tighten the screw without the pin on
the slider fitting properly in the hole in the
blade shank, the pin or the blade shank wig
be damaged. This may cause the blade to
be ejected unexpectedly during operation.
This can be extremely dangerous.
Blade H_S
To install the blade, loosen the screw on the blade clamp with the hex wrench 4.

piece. Do not allow the tool to bounce.
Bringthe bladeinto light contactwith the
workpiece.First,make a pilotgroove,using
a slowerspeed.Thenusea faster speedto
continuecutting.
CAUTION:
•Always use a suitable coolant (cutting oil) when cutting metal. Failure to do so wil{ cause
premature blade wear.
•Always wear gloves to protect your hands from hot flying chips when cutting metal.
•Always press the shoe firmly against the workpiece during operation. If the shoe is held
away from the workpiece during operation, strong vibration and/of twisting will be pro-
duoed, causing the blade to snap dangerously.
•Be sure to always wear suitable eye protection which conforms with current national
standard_
