GENERAL SAFETY RULES
(For All Tools)
WARNING! Read and understand all instructions. Failure
tofollow all instructions listed below, may result
in electric
shock, fire and/or serious personal injury.
SAVE THESE INSTRUCTIONS
READ ALL INSTRUCTIONS.
1. Keep your work area clean andwell lit. Clutteredbenchesand dark areas invite
accidents.
2. Do notoperatepowertools inexplosiveatmospheres, suchas in thepresence
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 loose control.
4. DoubleInsulated tools are equippedwitha polarized plug(one bladeiswider
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
H 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. Donotabusethe cord. Never usethe cordto carry the tools or pullthe plug
from anoutlet. Keep cordaway from heat, oil, sharp edgesor moving parts.
Replace damaged cords immediately. Damaged cords increase the risk of
electric shock.
8. Whenoperating a power tooloutside, use anoutdoor extension cordmarked
"W-A' or "W." These cords are rated for outdoor use and reduce the risk
of electric shock.
9. Stay alert, watch what youaredoing andusecommonsense whenoperating
a power tool. Do not use tool while tired or under the influence of drugs,
alcohol, or medication.
A moment of inattentionwhile operating power tools
may result in serious personal injury.
IO. Dress properly. Do not wear looseclothing orjewelry. Contain longhair. Keep
your hair, clothing, andgloves away from movingparts. 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 onthe switch or plugging intools 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. Donotoverreach. Keepproperfooting and balanceat alltimes. Properfooting
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.
15. Use clamps or other practical way to secure and support the workpiece to
a stable platform. Holdingthe work by hand or against your body is unstable
and may lead to
loss of control.
16. Donotforce tool. Usethe correct toolfor 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 plugfrom 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
maintainedtools,
with sharp cutting edges are less likelytobind 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 service before using. Many accidents are caused by poorly maintained
tools.
22. Use only accessories that are recommended by the manufacturer for your
model. Accessoriesthat may be suitable for one
tool, may become hazardous
when used on another tool.
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 identicalreplacement parts. Follow instruc-
tions
in the Maintenance section of this manual. Use of unauthorized parts
or failure tofollow Maintenance Instructions may create a riskof electric shock
of injury.

Installingor removing the saw blade
CAUTION:
Always be sure that the tool
is switched off and unpluggedbefore installingor removing
the blade.
To install the blade, loosen the screw on
With the blade teeth facing forward, insert
1
the blade into the blade holder as far as it
will go. Make sure that the back edge of
the blade fits properly inthe groove of the
roller. Then firmly tighten the screw to

CAUTION :
*Always secure the blade firmly. Insufficient securing of the blade may cause blade
breakage or serious injury.
Always cleanout the blade holder before installingthe blade. Chips or foreign matter on
the blade holder may cause insufficient securing
of the blade.
*Use
a lubricant or cutting oil between the blade and roller when cutting iron or com-
position board,
etc. Failureto do so will shortenthe service life of your blade and roller
or lead to potentially dangerous blade breakage.

Installingthe universalshank jig saw blade
CAUTION :
Always be sure that the tool is switched off and unpluggedbefore installingor 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" 1.
c
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.
Selecting

This tool can be operated with an orbital
or
a straight line cutting action. To change
the cutting action, just turn the lever tothe
desired cutting action position. Refer to

Refer to the table at right to select the
proper speed for the workpiece to be cut.
However, the appropriate speed may differ
with the type or thickness of the work-
piece. In general, higher speeds will allow
you to cut workpieces faster but the
service
life of the bladewill be reduced.

at any angle between 0" and 45' (left
or right). Loosen the bolt on the bottom of
the tool. Move the base
so that the bolt is
positioned inthe 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 graduations.
Then tighten the bolt to secure the base.

Cutouts can be made with either of two methods A or B.
A) Boring a starting hole:
For internal cutouts without
a lead-incut from an edge, predrill starting hole more
than
12 mm (15/32") in diameter. Insert the blade into this hole and hold the tool
firmly against the workpiece to start your cut.

To trim edges or make slight dimensional adjustments, run the blade lightly along the cut
edges.

Metal cutting
Always use a suitablecoolant (cuttingoil)when cutting metal. Failureto do so will cause
significant blade wear. The underside of the workpiece can be greased insteadof using
a
coolant.
Plastic base plate
Use the plastic base plate when cutting
decorative veneers, plastics,
etc. It protects
sensitive or delicate surfaces from damage.
To replace the base plate, remove the four
screws with the hex wrench.
Anti-splinteringdevice
To reduce the potential for workpiece sur-
face splintering, the anti-splintering device
can be used. Fit
it into the base from
below
so that it surrounds the sides of the
blade.

Guide rule (ripfence; optional accessory)
When cutting widths of under 150 mm
(5-29/32") repeatedly, use of the guide
rule will assure fast, clean, straight cuts.
To
install it, loosen the bolt on the front of
the base. Slip in the guide rule and secure
the bolt.
Circularguide (optional accessory)
Use of the circular guide insures clean,
smooth cutting of circles under
200 mm
(7-7/8") in radius. Insert the pin through
the center hole and secure
it with the
threaded knob. Move the base of the tool
fully forward. Then install the circular
guide on the base in the same manner
as
the guide rule (ripfence).
Vacuum head (optional accessory)
The vacuum head is recommended to per-
form clean cutting operations. Install the
plastic cover on the tool by fitting
it into
the notches inthe tool.
