GENERAL SAFETY PRECAUTIONS
(For All Tools)
1. KNOW YOUR POWER TOOL. Read the owner's manualcarefully. Learnthe
tools applications and limitations, as well as the specific potential hazards
peculiar to
it.
2. KEEP GUARDS IN PLACE and in working order.
3. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keysand adjusting wrenches are removed from tool before turning
it on.
4. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
5. DON'T USE INDANGEROUSENVIRONMENT. 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 CHILDREN AWAY. 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.
IO. WEAR PROPER APPAREL. Wear no loose clothing, gloves, neckties, rings,
bracelets, or other jewelry which may get caught in moving parts. Nonslip
footwear is recommended. Wear protective hair coveringtocontain longhair.
11. ALWAYS USE SAFETY GLASSES. Also use face or dust mask if cutting
operation is dusty. Everyday eyeglasses only have impact resistant lenses,
they are NOT safety glasses.
12. SECURE WORK. Useclamps or a vise to holdwork 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 lubricatingand changing acces-
sories.
15. DISCONNECTTOOLS before servicing; when changing accessories such as
blades, bits, cutters, and the like.

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
in
line voltage resulting in loss of power and overheating. Table 1 shows the
correct size touse depending oncord length and nameplate ampere rating.
If
in doubt, usethe next heavier gage. The smaller the gage number, the heav-
ier the cord.

Operation
CAUTION:
*Before use, be sure to releasethe handlefrom the lowered position by pulling the stop-
per pin.
*Make sure the bladeis not contacting the workpiece, etc. beforethe switch is turned on.
*Do not apply excessive pressureon the handlewhen cutting. Too muchforce may result
inoverloadof the motor and/or decreasedcutting efficiency.
*Gently press down the handle to perform the cut. If the handle is pressed down with
force or if lateralforce is applied, the bladewill vibrate and leave
a mark (sawmark)inthe
workpiece and the precision
of the cut will be impaired.
When cutting with this tool, the thickness
of the blade is cut out of the workpiece as
well. Therefore,your cutting line should be
on either the left or right side
of the groove
in the kerf board. Switch on the tool and
wait until the blade attainsfull speed before
lowering gently into the cut. When the
I----+
blade, contacts the workpiece, gradually
bear down on the handle to perform the
cut. When the cut is completed, switch off
the tool and WAIT UNTIL THE BLADE HAS
COME TO A COMPLETE STOP before
returningthe bladeto its fully elevatedposi-
tion
. A thin piece of cut off material could
otherwise contact the coastingbladeand bethrown arounddangerously.
CAUTION:
When cutting long workpieces, use sup-
ports that are as high as the top surface
levelof the turn base.
1. Miter cutting
Referto the previouslycovered "Positioning for adjusting the miter angle"

2. Bevel cut
*Left 0" - 45' bevelcuts can be performed.
*Loosen the lever and
tilt the saw blade
to set the bevel angle. Switch on the
tool and wait until the blade attains full
speed. Then gently lower the handleto
the fully lowered position while applying
pressure inthedirection of the arrow (in
parallelwith the blade).When the cut is
completed, switchoff thetool andWAIT
UNTIL THE BLADE HAS COME
TO A
COMPLETE STOP before returning the
bladeto itsfully elevated position.
Apply pressure in the
directionof the arrow
(in
parallel withthe blade)
WARNING:
Never use your hand to hold the workpiece that requires your hand to be any closer
than
4" from the blade area. In this case, always use the optional vise to secure the
workpiece. After any cutting operation, raise the blade gently. NEVER raise the blade
until
it has cometo a complete stop. Seriousinjury may result.
CAUTION:
*When performingthe bevel cut with the workpiece secured on the left side of the turn
base, it
will create a condition where the piececut off will come to rest on the blade. If
the bladeis raisedwhile the blade isstill rotating, this piece may be caught inthe blade,
causing fragments to be scattered around which is dangerous. The blade should be
gently raisedonly after the blade has come to a complete stop.
*When pressingdownthe handle,apply pressure inthedirection
of the arrow (inparallel
with the blade). If
a force is applied perpendicularlyto the turn base or if the pressure
direction is changedduring
a cut, the precision of the cut will be impaired.
