1. KNOW YOUR POWER TOOL. Readthe owner's manual carefully. Learn the
tools applications and limitations, as well as the specific potential hazards
peculiar to
it.
2. KEEP GUARDS IN PLACE and in working order.
3. REMOVEADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keysand adjusting wrenches are removed from tool beforeturning
it on.
4. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
5. DON'T USE INDANGEROUS ENVIRONMENT. Don't usepower tools indamp
or wet locations, or expose them to rain. Keep work area well lighted.
Don't use tool
in presence of flammable liquids or gases.
6. KEEP CHILDRENAWAY. All visitors should be kept safe distance from work
area.
7. MAKE WORKSHOP KID PROOF with padlocks, master switches, or by
removing starter keys.
8. DON'T FORCETOOL. It will do thejob better and safer at the ratefor which
it was designed.
9. USE RIGHT TOOL. Don't force tool or attachment to do a job for which it
was not designed.
10. WEAR PROPER APPAREL. Wear no loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get caught
in moving parts. Nonslip
footwear isrecommended. Wear protective haircoveringtocontain longhair.
11. ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting
operation isdusty. Everyday eyeglasses only have impact resistant lenses,
they are NOT safety glasses.
12. SECURE WORK. Useclamps or avise toholdwork when practical. It's safer
than using your hand and
it frees both hands to operate tool.
13. DON'T OVERREACH. Keep proper footing and balance at all times.
14. MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for best and
safest performance. Follow instructions for lubricating andchanging acces-

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 undersizedcord will cause a drop
in
line voltage resulting in loss of power and overheating. Table 1 shows the
correct size to usedepending on cord length and nameplate ampere rating.
If
in doubt, usethe nextheavier gage. The smaller the gage number, the heav-
ier the cord.

17. REDUCE THE RISK OF UNINTENTIONALSTARTING. Make sure switch is
in off position before plugging in.
18. USE RECOMMENDED ACCESSORIES. Consult the owner's manual for
recommendedaccessories.The useof improper accessoriesmay cause risk
of injury to persons.
19. NEVER STAND ON TOOL. Serious injurycould occur if the toolistipped or
if the cutting tool is accidentally contacted.
20. CHECK DAMAGED PARTS. 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 its intended function - check for alignment
of moving parts, binding of movingparts, breakageof parts, mounting, and
anyother conditionsthat mayaffect itsoperation. A guardor otherpart that
is damaged should be properly repaired or replaced.
21. DIRECTIONOF FEED. Feed work into a blade or cutter against the direction
of rotation of the blade or cutter only.
22. NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don't
leave tool until
it comes to a complete stop.
23. When servicing use only identical replacement parts.
24. POLARIZEDPLUGS. To reducethe riskof electric shock, this equipment has
a polarized plug (one blade is wider than the other). This plug
will fit in a
polarizedoutlet only one way. Ifthe plugdoes notfitfully
in theoutlet, reverse
the plug. If
it still does not fit, contact a qualified electrician to install the
proper outlet. Do not change the plug
in any way.

VOLTAGE WARNING: Before connecting the tooltoa power source (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 than that specified
for the tool can result inSERIOUS 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.

Press the shaft lock so that the blade can-
not revolve and use the socket wrench to
loosenthe hex bolt clockwise.Then remove
the hex bolt, outer flange and blade.
To install the blade, mount the blade onto
the spindle, making sure that the direction
of the arrow on the surface of the blade
matches the direction of the arrow on the
blade case. Install the outer flange and hex
bolt, and then use the socket wrench to
tighten the hex bolt securely counterclock-
wise while pressing the shaft lock. Then
tighten the hex bolt clockwise to secure
the center cover.

Positioning kerf boards
This tool is provided with kerf boards in the turn base.The kerf boardsare factory-adjusted
so that the saw bladedoes not contact the kerf boards. Before use, adjust the kerf boards
as follows:
First unplug the tool. Loosen the all screws
(2 each on left and right) which secure the
kerf boards. Retighten them to the extent
that the kerf boards can be easily moved
by hand. Lower the handle fully and press
the stopper pin to lock the handle in the
lowered position. Adjust the kerf boards
so that the kerf boards just contact the
sides
of blade teeth slightly. Tighten the all
screws (do not tighten firmly). After adjust-
ing the kerf boards, releasethe stopper pin
and raise the handle. Then tighten the
all
screws securely.
