IMPORTANT
SAFETY INSTRUCTIONS
(For All Tools)
WARNING: WHEN USINGELECTRICTOOLS, BASICSAFETY
PRECAUTIONSSHOULD ALWAYS BE FOLLOWEDTO REDUCE
THE RISK OF FIRE, ELECTRIC SHOCK, AND PERSONAL
INJURY, INCLUDING THE FOLLOWING:
READ ALL INSTRUCTIONS.
1. KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
2. CONSIDER WORK AREA ENVIRONMENT. Don't use power tools in damp
or wet locations. Keep work area well
lit. Don't expose power tools to rain.
Don't use tool
in presence of flammable liquids or gases.
3. KEEP CHILDREN AWAY. All visitors should be kept away from work area.
Don't let visitors contact tool or extension cord.
4. STORE IDLETOOLS. When not in use, toolsshould bestored in dry, andhigh
or locked-up place
- out of reach of children.
5. DON'T FORCE TOOL. It will dothejob better andsafer atthe ratefor which
it was intended.
6. USE RIGHT TOOL. Don't force small tool or attachment todo the job of a
heavy-dutytool. Don't usetoolfor purposenotintended; for example, don't
use circular saw for cutting tree limbs or logs.
7. DRESS PROPERLY. Don't wear looseclothing orjewelry. They can becaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protectivehair covering to contain long hair.
8. USE SAFETY GLASSES. Also use face or dust mask if cutting operation is
dusty.
9. DON'T ABUSE CORD. Never carry tool by cordor yank it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
IO. 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.
11. DON'T OVERREACH. Keep proper footing and balance at all times.
12. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructionsfor lubricatingand changing acces-
sories. Inspecttoolcords periodicallyand ifdamaged, have repairedbyautho-
rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease.
13. DISCONNECTTOOLS. When not in use, beforeservicing, and when chang-
ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys andadjusting wrenches are removed from toolbefore
turning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry toolwith finger onswitch.
Be sure switch is OFF when plugging
in.
16. EXTENSION CORDS. 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
inlinevoltage resulting in
loss of power and overheating. Table 1 shows the
correct size touse depending oncord lengthand nameplate ampere rating.
If in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

17. OUTDOOR USE EXTENSIONCORDS. When toolisused outdoors, use only
extension cords intended for use outdoors and
so marked.
18. STAY ALERT. Watch what you are doing, use common sense. Don't operate
tool when you are tired.
19. CHECK DAMAGEDPARTS. Before further use of the tool, a guard or other
part that is damaged should be carefully checked to determine that
it will
operate properly and perform itsintended function. Check for alignment of
moving parts, bindingof moving parts, 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 serv-
ice center unless otherwise indicated elsewhere inthis instruction manual.
Have defective switches replaced
by authorized service center. Don't use
tool
if switch does not turn it on and off.
20. GUARD AGAINST ELECTRIC SHOCK. Preventbody contact withgrounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
21. REPLACEMENT PARTS. When servicing, useonly identicalreplacementparts.
22. POLARIZEDPLUGS. To reduce the risk of electric shock, this equipment has
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 stilldoes notfit, contact a qualifiedelectrician toinstall
the proper outlet. Do not change the plug in any way.

VOLTAGE WARNING: Before connecting the tooltoa powersource (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplate of the tool. A power source with voltage greater thanthat 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.
ADDITIONAL SAFETY RULES
1. Avoid cutting nails. Inspectfor and removeall nails from the workpiece before
2. Don't cut hollow pipe.
3. Do not cut oversize workpiece.
4. Check for the proper clearance beneath the workpiece before cutting so that
5. Always wear eye protection conforming with current national standard.

Bevel cutting
CAUTION
:
Always unplugthe tool before makingany adjustments.
With the base tilted, you can make bevel cuts
at any angle between 0' and 45' (left or
right). Loosen the base securing lever and move the base
so that the dent mark in the
motor housing
is aligned with the slot in the base. Tilt the base until the desired bevel
angle
is obtained. The edge of the motor housing indicatesthe bevel angle by graduations.
Then tighten the base securing lever tosecure the base.
NOTE :
Always remove the plastic cover (chip shield) from the tool when you make bevel cuts
usingan optional guide rule (ripfence) or circular guide.

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 and edge, pre-drill starting hole
more than 12mm (15/32") indiameter.
Insert the blade into this hole and hold
the tool firmly against the workpiece
to start your cut.
B) Plungcutting:
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 posi-
tioned just above the workpiece sur-
face.
2. Apply firm 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.

Finishing edges
To trim edges or make slight dimensional
adjustments, runthe blade lightly alongthe
cut edges.
//
Metal cutting
Always use
a suitablecoolant (cuttingoil) when cuttingmetal. Failure to do so will cause
significant blade wear. The underside of the workpiece can be greased insteadof using
a
coolant.
Plasticbase plate
Use the plastic base plate when cuttingde-
corative veneers, plastics,
etc. l t protects
sensitive or delicate surfaces from damage.
To replace the base plate, remove the four
screws.
Anti-splintering device
To reduce the potential for workpiece
surface splintering, the anti-splintering
device can be used. Fit
it into the base
from below
so that it surrounds the sides
of the blade.
