CUTTING PROCEDURES

DANGER:

Keep hands away from cutting area and the

blade. Keep your second hand on auxiliary

handle, or motor housing. If both hands are

holding the saw, they cannot be cut by the blade.

 Do not reach underneath the workpiece. The

guard can not protect you from the blade below the

workpiece.

 Adjust the cutting depth to the thickness of the

workpiece. Less than a full tooth of the blade teeth

should be visible below the workpiece.

 Never hold piece being cut in your hands or across

your leg. Secure the workpiece to a stable platform.

It is important to support the work properly to minimize

body exposure, blade binding, or loss of control.



Hold the power tool by insulated gripping surfaces

only, when performing an operation where the cutting

tool may contact hidden wiring.

Contact with a “live”

wire will also make exposed metal parts of the power

tool “live” and could give the operator an electric

shock.

 When ripping, always use a rip fence or straight

edge guide. This improves the accuracy of cut and

reduces the chance of blade binding.

 Always use blades with correct size and shape

(diamond versus round) of arbour holes. Blades that

do not match the mounting hardware of the saw will

run eccentrically, causing loss of control.

 Never use damaged or incorrect blade washers

or bolt. The blade washers and bolt were specially

designed for your saw, for optimum performance and

safety of operation.

KICKBACK CAUSES AND RELATED WARNINGS

 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 rapidly 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 toward the operator.

Kickback is the result of saw misuse and/or incorrect

operating procedures or conditions and can be avoided

by taking proper precautions as given below:

 Maintain a firm grip with both hands on the saw

and position your arms to resist kickback forces.

Position your body to either side of the blade, but

not in line with the blade. Kickback could cause the

saw to jump backwards, but kickback forces can be

controlled by the operator, if proper precautions are

taken.

 When blade is binding, or when interrupting a cut

for any reason, release the trigger and hold the saw

motionless in the material until the blade comes

to a complete stop. Never attempt to remove the

saw from the work or pull the saw backward while

the blade is in motion or kickback may occur.

Investigate and take corrective actions to eliminate the

cause of blade binding.

 When restarting a saw in the workpiece, centre

the saw blade in the kerf and check that saw teeth

are not engaged into the material. If saw blade is

binding, it may walk up or kickback from the workpiece

as the saw is restarted.

GENERAL POWER TOOL SAFETY WARNINGS

CIRCULAR SAW SAFETY WARNINGS

BATTERY TOOL USE AND CARE

 Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one type

of battery pack may create a risk of fire when used with

another battery pack.

 Use power tools only with specifically designated

battery packs. Use of any other battery packs may create

a risk of injury and fire.

 When battery pack is not in use, keep it away from

other metal objects, like paper clips, coins, keys, nails,

screws or other small metal objects, that can make a

connection from one terminal to another. Shorting the

battery terminals together may cause burns or a fire.

 Under abusive conditions, liquid may be ejected from

the battery; avoid contact. If contact accidentally

occurs, flush with water. If liquid contacts eyes,

additionally seek medical help. Liquid ejected from the

battery may cause irritation or burns.

SERVICE

 Have your power tool serviced by a qualified repair

person using only identical replacement parts. This will

ensure that the safety of the power tool is maintained.

 When servicing a power tool, use only identical

replacement parts. Follow instructions in the

Maintenance section of this manual. Use of unauthorized

parts or failure to follow Maintenance instructions may

create a risk of shock or injury.
