GENERAL SAFETY PRECAUTIONS
(For All Tools)
1. KNOW YOUR POWER TOOL. Read the 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. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removedfrom tool before turning
it on.
4. KEEP WORK AREA CLEAN. Cluttered areas and benches invite accidents.
5. DON'T USE INDANGEROUSENVIRONMENT. Don't use power 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 andsafer atthe 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 isrecommended.Wear protective hair covering tocontain 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 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 lubricatingand changing acces-
sories.
15. DISCONNECTTOOLS before servicing; when changingaccessories suchas
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 to use depending oncord length and nameplate ampere rating.
If indoubt, usethe next heaviergage. The smaller the gage number, the heav-
ier the cord.

recommendedaccessories. The use of improper accessories may cause risk
of injury to persons.
NEVER STAND ON TOOL. Serious injury could occur
if the tool is tipped or
if the cutting tool is accidentally contacted.
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 intendedfunction
- check for alignment
of moving parts, binding of moving parts, breakage of parts, mounting, and
any other conditions that may affect itsoperation. A guard or other part that
is damaged should be properly repaired or replaced.
DIRECTION OF FEED. Feed work intoa blade or cutter against the direction
of rotation of the blade or cutter only.
NEVER LEAVE TOOL RUNNING UNATTENDED. TURN POWER OFF. Don't
leave tool
until it comes to a complete stop.
When servicing use only identical replacement parts.
POLARIZEDPLUGS.To reducethe risk of 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.
If the plugdoes not fit fully in the outlet, 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.

Kerf board
This tool is provided with the kerf board in
the turn base. If the kerf groove has not yet
been cut in the kerf board by the factory,
you should cut the groove before actually
using the tool to cut
a workpiece. Switch
on the tool and lower the blade gently to
cut
a groove inthe kerf board.
Maintaining maximum cutting capacity
Unplugthe tool beforeany adjustment is attempted.
This tool is factory adjusted to provide the max. cutting capacity for
a 255 mm (IO") saw
blade. When the diameter of the blade has been reduced due to sharpening, adjust the
depth adjusting bolt by turning
it with the socket wrench. The saw blade is lowered by
turning the depth adjusting bolt counterclockwise and raised
by turning it clockwise. Adjust
so that when the handle is in the fully lowered position, there will be a distance of about
130 mm (5-1/8") from the front face of the guide fence to the point where the front edge
of the bladeenters the kerf.With the tool unplugged, rotate the blade by handwhile hold-
ing the handle all the way down. Be sure that the blade does not contact any part
of the
