KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
CONSIDER WORK AREA ENVIRONMENT.Don't use power tools in damp
or wet locations. Keep work area well
lit. Don't expose power tools torain.
Don't use tool
in presence of flammable liquids or gases.
KEEP CHILDRENAWAY. All visitors should be kept away from work area.
Don't let visitors contact tool or extension cord.
STORE IDLETOOLS. When
not in use, tools should bestored in dry, andhigh
or locked-up place
- out of reach of children.
DON'T FORCETOOL.
It will do thejob better andsafer atthe ratefor which
it was intended.
USE RIGHT TOOL. Don't force small tool or attachment todo the job of a
heavy-dutytool. Don't usetool for purpose notintended; for example, don't
use circular saw for cutting tree limbs or logs.
DRESS PROPERLY. Don't wear looseclothingorjewelry. They can becaught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair coveringtocontain long hair.
USE SAFETY GLASSES. Also use face or dust mask if cuttingoperation is
dusty.
DON'T ABUSE CORD. Never carry tool by cordor yank
it todisconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
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.
DON'T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing acces-
sories. Inspecttool cords periodicallyandif damaged, have repairedbyautho-
rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECTTOOLS. When notinuse, beforeservicing, and whenchang-
ing accessories, such as blades, bits, cutters.

14. REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keysandadjustingwrenches are removed from
tool before turning
it on.
15. AVOID UNINTENTIONALSTARTING. Don't carry toolwithfinger onswitch.
Be sure switch is OFF when plugging
in.
16. EXTENSIONCORDS. 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 andoverheating. Table 1 shows the
correct size touse depending oncord lengthand nameplateampere rating.
If
in doubt, use the next heavier gage. The smaller the gage number, the
heavier the cord.

17. OUTDOOR USE EXTENSIONCORDS. When tool isusedoutdoors, use only
extension cords intended for use outdoors and
so marked.
18. STAY ALERT. Watch what you are doing, usecommon 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 andperform itsintendedfunction. Check for alignment of
movingparts, bindingof movingparts, breakageof parts, mounting, andany
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 unlessotherwise indicatedelsewhere
in this 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 with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
21
. REPLACEMENTPARTS. When servicing, useonly identicalreplacementparts.
22. 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
polarized outlet only one way. If the plug does not fit fully
in the outlet,
reversethe plug.
If it stilldoes notfit, contact aqualifiedelectriciantoinstall
the proper outlet.
Do not change the plug in any way.

VOLTAGEWARNING: Before connectingthe toolto a 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 toolcan result
in SERIOUS INJURY to the 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. Wear hearing protection.
2. Keep Guards In Place and In Working Order.
Never wedge or tie lower guardopen. Check operation of lower guard before
each use. Don’t use
if lower guard does not close briskly over saw blade.
CAUTION:
If saw isdropped, lowerguard may bebent, restricting full return.
3. Do not use blades which are deformed or cracked.
4. Do not use blades of high speed steel.
5. Keep Blades Clean and Sharp.
Sharp blades minimize stalling and kickback.
6. DANGER: Keep Hands Away From Cutting Area.
Keep hands away from blades. Don’t reach underneath work while blade is
rotating. Don’t attempt to remove cut material when blade
is moving.
CAUTION: Blades coast after turn off.
Large panels must be supported as shown
in Fig. 1 to minimize the risk of
blade pinching and kickback.
When cutting operation requires the resting of the saw on the work piece,
the saw shall be rested on the larger portion and the smaller piece cut off.
7. Support Large Panels.
To avoid kickback, do support board
or panel near the cut. Fig.
1
Don’t support board or panel away
from the cut.
8. Use Rip Fence.
Always use a fence or straight edge guide when ripping.

9. Guard Against Kickback.
Kickback occurs whenthe saw stalls rapidly andisdrivenback towards the
operator. Releaseswitch immediately
if blade bindsor saw stalls. Keepblades
sharp. Support large panels as shown in Fig.
1. Use fence or straight edge
guidewhen ripping. Don't force tool. Stay alert exercisecontrol. Don't remove
saw from work during a cut while the blade is moving.
NEVER place your hand or fingers
behind the saw. If kickback occurs,
the saw could easilyjump backwards
over your hand, possibly causing
severe injury.

IO. Lower Guard. Raise lower guard with the retracting handle.
11. Adjustments. Before cutting be sure depth and beveladjustmentsaretight.
12. Use Only Correct Blades In Mounting. Don't use blades with incorrect size
13. Avoid Cutting Nails. Inspect for and remove all nails from lumber before
cutting.
14. When operating the saw, keep the
cordaway from the cuttingarea and
position
it so that it willnotbe caught
onthe workpiece during the cutting
operation.
Operate with proper hand support,
proper workpiece support, and
supply cord routing away from the
work area.
