Do not abuse the cord. Never use the cord for carrying,

pulling or unplugging the power tool. Keep cord away

from heat, oil, sharp edges and moving parts. Damaged

or entangled cords increase the risk of electric shock.

When operating a power tool outdoors, use an exten-

sion cord suitable for outdoor use. Use of a cord suitable

for outdoor use reduces the risk of electric shock.

If operating a power tool in a damp location is unavoid-

able, use a residual current device (RCD) protected

supply. Use of an RCD reduces the risk of electric shock.

Personal safety
f

Stay alert, watch what you are doing and use common

sense when operating a power tool. Do not use a power

tool while you are tired or under the influence of drugs,

alcohol or medication. A moment of inattention while op-

erating power tools may result in serious personal injury.

Use personal protective equipment. Always wear eye

protection. Protective equipment such as dust mask,

non-skid safety shoes, hard hat, or hearing protection

used for appropriate conditions will reduce personal inju-

ries.

Prevent unintentional starting. Ensure the switch is in

the off-position before connecting to power source

and/or battery pack, picking up or carrying the tool.

Carrying power tools with your finger on the switch or en-

ergising power tools that have the switch on invites acci-

dents.

Remove any adjusting key or wrench before turning

the power tool on. A wrench or a key left attached to a ro-

tating part of the power tool may result in personal injury.

Do not overreach. Keep proper footing and balance at

all times. This enables better control of the power tool in

unexpected situations.

Dress properly. Do not wear loose clothing or jewel-

lery. Keep your hair, clothing and gloves away from

moving parts. Loose clothes, jewellery or long hair can be

caught in moving parts.

If devices are provided for the connection of dust ex-

traction and collection facilities, ensure these are con-

nected and properly used. Use of dust collection can re-

duce dust-related hazards.

Power tool use and care
f

Do not force the power tool. Use the correct power tool

for your application. The correct power tool will do the

job better and safer at the rate for which it was designed.

Do not use the power tool if the switch does not turn it

on and off. Any power tool that cannot be controlled with

the switch is dangerous and must be repaired.

Disconnect the plug from the power source and/or the

battery pack from the power tool before making any

adjustments, changing accessories, or storing power

tools. Such preventive safety measures reduce the risk of

starting the power tool accidentally.

Store idle power tools out of the reach of children and

do not allow persons unfamiliar with the power tool or

these instructions to operate the power tool. Power

tools are dangerous in the hands of untrained users.

Maintain power tools. Check for misalignment or bind-

ing of moving parts, breakage of parts and any other

condition that may affect the power tool’s operation. If

damaged, have the power tool repaired before use.

Many accidents are caused by poorly maintained power

tools.

Keep cutting tools sharp and clean. Properly maintained

cutting tools with sharp cutting edges are less likely to bind

and are easier to control.

Use the power tool, accessories and tool bits etc. in ac-

cordance with these instructions, taking into account

the working conditions and the work to be performed.

Use of the power tool for operations different from those

intended could result in a hazardous situation.

Service
f

Have your power tool serviced by a qualified repair per-

son using only identical replacement parts. This will en-

sure that the safety of the power tool is maintained.

Safety Warnings for Circular Saws

Cutting procedures
f

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 work-

piece. 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 im-

portant to support the work properly to minimize body ex-

posure, blade binding, or loss of control.

Hold the power tool by the insulated gripping surfaces

only, when performing an operation where the cutting

tool may contact hidden wiring or its own cord. 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 (dia-

mond versus round) of arbour holes. Blades that do not

match the mounting hardware of the saw will run eccentri-

cally, 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;
