GENERAL SAFETY INSTRUCTIONS

FOR POWER TOOLS

1. KNOW YOUR TOOL. Read and under-

stand the owners manual and labels af-

fixed to the tool. Learn its application and

limitations as well as its specific potential

hazards.

2. GROUND THE TOOL. This tool is

equipped with an approved 3-conductor

cord and a 3-prong grounding type plug to

fit the proper grounding type recep-tacle.

The green conductor in the cord is the

grounding wire. NEVER connect the

green wire to a live terminal.

3. KEEP GUARDS IN PLACE. Keep in

good working order, properly adjusted and

aligned.

4. REMOVE ADJUSTING KEYS AND

WRENCHES. Form habit of checking to

see that keys and adjusting wrenches are

removed from tool before turning it on.

5. AVOID DANGEROUS ENVIRONMENT.

Don’t use power tools in damp or wet lo-

cations or expose them to rain. Keep work

area well lit and provide adequate sur-

rounding work space.

6. KEEP CHILDREN AWAY. All visitors

should be kept a safe distance from work

area.

7. MAKE WORKSHOP CHILD-PROOF.

Use padlocks, master switches or remove

starter keys.

8. USE RIGHT TOOL. Don’t force the tool or

the attachment to do a job for which it was

not designed.

9. WEAR PROPER APPAREL. Do not wear

loose clothing, gloves, neckties or jewelry

(rings, watch) because they could get

caught in moving parts. Non-slip footwear

is recommended. Wear protective hair

covering to contain long hair. Roll up long

sleeves above the elbows.

10. ALWAYS WEAR SAFETY GLASSES.

Always wear safety glasses (ANSI

Z87.1). Everyday eyeglasses only have

impact resistant lenses, they are NOT

safety glasses. Also use a face or dust

mask if cutting operation is dusty.

11. DON’T OVERREACH. Keep proper foot-

ing and balance at all times.

12. MAINTAIN TOOL WITH CARE. Keep

tools sharp and clean for best and safest

performance.

13. DISCONNECT TOOLS. Before servic-

ing, when changing accessories or at-

tachments.

14. AVOID ACCIDENTAL STARTING.

Make sure the switch is in the ‘’OFF’’ po-

sition before plugging in.

15. NEVER STAND ON TOOL. Serious in-

jury could occur if the tool tips over. Do

not store materials such that it is neces-

sary to stand on the tool to reach them.

16. CHECK DAMAGED PARTS. Before fur-

ther use of the tool, a guard or other parts

that are damaged should be carefully

checked to ensure that they will operate

properly and perform their intended func-

tion. Check for alignment of moving parts,

breakage of parts, mounting, and any

other conditions that may affect its oper-

ation. A guard or other parts that are

damaged should be properly repaired or

replaced.

17. NEVER LEAVE MACHINE RUNNING

UNATTENDED. Turn power ‘’OFF’’.

Don’t leave any tool running until it

comes to a complete stop.

SPECIFIC SAFETY INSTRUCTIONS

FOR CIRCULAR SAWS

Snagging the lower guard on a surface

below the material being cut can momentar-

ily reduce operator control. The saw can lift

partially out of the cut increasing the chance

of blade twist. Make sure there is sufficient

clearence under the workpiece.

DANGER! KEEP HANDS AWAY FROM

CUTTING AREA. Keep hands away from

the blade. Never place hands infront or be-

hind the path of the blade while cutting.

Keep your second hand on the auxiliary han-

dle or motor housing. If both hands are hold-

ing the saw, they can not be cut by the

blade.

•SUPPORT LARGE PANELS. Large panels

must be supported to minimize the risk of

blade pinching and kickback.

• ADJUSTMENTS. Before cutting, be sure

the depth and bevel adjustments are tight.

•DANGER! RELEASE SWITCH IMMEDI-

ATELY IF THE BLADE BINDS OR IF THE

CIRCULAR SAW STALLS.

• Keep your body positioned to either side of

the saw blade, but not in line with the saw

blade. A kickback could cause the saw to

jump backwards.

• Do not reach underneath the workpiece.

The guard cannot protect you from the

blade below the workpiece.

• Check lower guard for proper closing be-

fore each use. Do not operate saw if lower

guard does not move freely and close in-

stantly. Never clamp or tie the lower guard

into the open position.

• The lower guard should be retracted

manually only for special cuts such as

“Pocket Cuts & Compound Cuts”. Raise

the lower guard using the retracting lever.

As soon as the blade enters the material,

the lower guard must be released.

• Never hold piece being cut in your hands

or across your leg(s). It is important to sup-

port the workpiece properly to minimize

body exposure, blade binding, or loss of

control.

• When ripping, always use the straight edge

guide. This improves the accuracy of the

cut and reduces the chance of blade bid-

ding.

• Never use damaged or incorrect blade

washer and bolt. The blade washer and

bolt were specially designed for your saw,

for optimum performance and safety of op-

eration.

ELECTRICAL INFORMATION

WARNING: The warnings, cautions, and instructions discussed in this instruction manual

cannot cover all possible conditions and situations that may occur. It must be understood

by the operator that common sense and caution are factors which cannot be built into this

product, but must be supplied by the operator. Performance of this tool may vary depending

on variations in local line voltage. Extension cord usage may also affect tool performance.

VOLTAGE WARNING

Before connecting the tool to a power source (receptacle, outlet, ect.) be sure the voltage

supplied is the same as that specified on the nameplate of the tool. If one says 120V and

the other says 115V then there will be no complications. Never try to plug a 120V tool into

a 240V outlet, or the other way around. A voltage greater than that specified on the tool

can result in SERIOUS INJURY to the user, as well as damage to the tool. If in doubt, DO

NOT PLUG IN THE TOOL.

WARNING: YOUR CIRCULAR SAW MUST BE CONNECTED TO A 120V, 15-AMP,

BRANCH CIRCUIT BREAKER. FAILURE TO CONNECT IN THIS WAY CAN RESULT IN

INJURY FROM SHOCK OR FIRE.

DOUbLE INSULATION

Double insulated tools are equipped with a polarized

two-prong 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 into the outlet, reverse the

plug. If it still does not fit, contact a qualified electrician

to install a polarized outlet. Do not alter or change the

plug in any way. Double insulation eliminates the need

for three wire grounded power supply and grounded

power cords.

ExTENSION CORDS

Improper use of extension cords may cause in-

efficient operation of your tool which can result in

overheating. Be sure your extension cord is rated

to allow sufficient current flow to the motor. If you

are using the tool outdoors, use an extension

cord rated for outdoor use (signified by “WA” on

the jacket).

The extension cord must have a minimum wire

size depending on the amperage of the tool and the length of the extension cord. This size

is determined by its AWG (American Wire Gauge) rating. The smaller the gauge, the greater

the cable’s capacity. The amount of cords used does not matter: Total length determines

the minimum AWG rating. Every cord must meet the AWG rating. Use the chart in Fig.2 to

determine what AWG rating is required for your situation.

CAUSES & OPERATOR PREVENTION

OF KICKbACK

CAUSES & OPERATOR PREVENTION

OF KICKbACK

• Kickback is a sudden reaction to a pinched,

bound or misaligned saw blade, causing

an uncontrolled saw to lift up and out of

the workpiece toward the operator.

• When the blade is pinched or bound

tightly by the kerf closing down, the blade

stalls and the motor reaction drives the

unit rapidely back toward the operator.

• If the blade becomes twisted or misaligned

in the cut, the teeth at the back edge of

the blade can dig into the top surface of

the wood causing the blade to climb out

of the kerf and jump back at the operator.

• Kickback is the result of tool misuse and/or

incorrect operating procedures or condi-

tions and can be avoided by taking proper

precautions as given below.

• Maintain a firm grip with both hands on the

saw and position your body and arm to

allow you to resist Kickback forces. Kick-

back forces can be controlled by the op-

erator if proper precautions are taken.

• When blade is binding or when interrup-

ting a cut for any reason, release the

trigger and hold the saw motionless in the

material until the blade comes to a com-

plete stop. Never attempt to remove the

saw from the work or pull the saw back-

ward while the blade is in motion or Kick-

back may occur. Investigate and take

corrective measures to eliminate the

cause of blade binding.

• When restarting a saw in the workpiece,

center the saw blade in the kerf and

check that the saw teeth are not engaged

into the material. If the saw blade is bind-

ing it may walk up or Kickback from the

workpiece as the saw is restarted.

• Support large panels to minimize the risk

of blade pinching and Kickback. Large

panels tend to sag under their own

weight. Support must be placed under the

panel on both sides, near the line of cut

and near the edge of the panel.

• Do not use dull or damaged blade. Un-

sharpened or improperly set blades pro-

duce narrow kerf causing excessive

friction, blade binding and Kickback.

• Blade depth and bevel adjusting locking

levers must be tight and secure before

making cut. If blade adjustment shifts

while cutting, it may cause binding and

Kickback.

Use extra caution when making a “Pocket

Cut” into existing walls or other blind areas.

The protruding blade may cut objects that

can cause Kickback.

TO REDUCE THE RISK OF KICKbACK:

• Keep a firm grip on the saw with both

hands at all times.

• Stay alert-exercise control.

• Support long overhanging materials. As the

material is cut and weakens, it will sag,

causing a pinched blade.

• Support large panels. Material supported

only at the ends will to blade pinching.

ASSEMbLY/ADJUSTMENTS

Warning! Always unplug saw from power

source before any of the following operations

or instructions.

ATTACHING bLADE

Note: The first time the blade cap screw (C)

Fig.3 is removed from saw without a blade in-

stalled, it may be necessary to place the

blade hex. key on the cap screw head and

tap it sharply in the counterclockwise direc-

tion. Retract lower blade guard and position

the blade (A) Fig.3 and outer washer (B) on

the saw arbor shaft. Make sure the large sur-

face of outer washer (B) is toward blade. To

prevent blade rotation while tightening the

blade cap screw, you can raise the lower

guard and place the saw down on a piece of

scrap wood. The blade teeth will dig into the

scrap and prevent rotation while you tighten

the blade clamping bolt, or you can press the

spindle lock lever (A) Fig.4 to lock the arbor

shaft. Tighten blade cap screw (C) Fig.3 se-

curely using the supplied 6mm hex. key.

ATTACHING EDGE GUIDE

Unscrew the edge guide lock knob (A) Fig.5

on the base plate (B). Slide the edge guide

retighten the edge guide lock knob (A).

SETTING THE bEVEL ANGLE

Adjust the bevel angle by loosening the bevel

adjustment knob (E) Fig.5, use the bevel scale

(F) as a guide and tilt the base to the desired

bevel angle. Retighten bevel adjustment knob.

SETTING THE CUTTING DEPTH

Adjust depth of cut by lifting the depth lever (A)

Fig.6 upwards, set the base to the desired

depth. Lower the depth lever to secure the

depth adjustment.

TURNING SAW ON

This saw comes with a safety feature which

prevents accidental starts. To turn the saw on,

press and hold the safety button (A) Fig.7 and

then pull on the trigger (B).

CLEANING AND MAINTENANCE

TURN OFF AND UNPLUG THE SAW WHEN

PERFORMING ANY CLEANING OR OTHER

MAINTENANCE.

Regular cleaning is required for the safe oper-

ation of the tool, as an excessive build up

of dust will prevent the tool from operating

correctly.

• Keep the cooling vents on the motor

housing clean and unobstructed at all times.

• Never use any caustic agents or solvents to clean the plastic parts. Use only mild soap

and a damp cloth to clean the tool. Never let any liquid get inside the saw, never immerse

any part of the saw into a liquid.

blades

Always use a sharp blade. If the tool does not cut as well as expected or if it overheats

the most common cause is a blunt blade. It is difficult to see or feel if the blade is blunt.

When in doubt use a new blade.

• Replacement blades are available at your nearest distributor of King Canada products.

IMPORTANT: To assure product safety and reliability, repairs, maintenance and adjustment

should be performed by one of our authorized service centers or other qualified service

technicians, as always using identical replacement parts.
