SAFETY PRECAUTIONS
1) WORK AREA SAFETY
a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b. Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks which may ignite the
dust or fumes.
c. Keep children and bystanders away while operating a power tool. Distractions
can cause you to lose control.
2) ELECTRICAL SAFETY
a. Power tool plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with earthed (grounded) power tools. Unmodified
plugs and matching outlets will reduce risk of electric shock.
b. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators,
ranges and refrigerators. There is an increased risk of electric shock if your body is
earthed or grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool
will increase the risk of electric shock.
d. 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 or moving parts.
Damaged or entangled cords increase the risk of electric shock.
e. When operating a power tool outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric
shock.
f. If operating a power tool in a damp location is unavoidable, use a residual
current device (RCD) protected supply. Use of an RCD reduces the risk of electric
shock.
3) PERSONAL SAFETY
a. 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 operating power
tools may result in serious personal injury.
b. 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 injuries.
WARNING: READ ALL INSTRUCTIONS. FAILURE TO FOLLOW ALL
INSTRUCTIONS LISTED BELOW MAY RESULT IN ELECTRIC SHOCK, FIRE AND/
OR SERIOUS INJURY. THE TERM “POWER TOOL” IN ALL WARNINGS LISTED
BELOW REFERS TO YOUR 20V CORDLESS CIRCULAR SAW.

Parts & Service: 020 8988 7400 / E-mail: [e-mail] or [e-mail]
c. 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 energising power tools
that have the switch on invites accidents.
d. Remove any adjusting key or wrench before turning the power tool on. A wrench
or a key left attached to a rotating part o the power tool may result in personal
injury.
e. Do not overreach. Keep proper footing and balance at all times. This enables
better control of the power tool in unexpected situations.
f. Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewellery or long hair can be
caught in moving parts.
g. If devices are provided for the connection of dust extraction and collection
facilities, ensure these are connected and properly used. Use of dust collection
can reduce dust-related hazards.
4) POWER TOOL USE AND CARE
a. 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.
b. 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.
c. 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.
d. 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.
e. Maintain power tools. Check for misalignment or binding 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.
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are easier to control.
g. Use the power tool, accessories and tool bits etc. in accordance 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.
5. BATTERY TOOL USE AND CARE
a. 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.
b. Use power tools only with specifically designated battery packs. Use of any other
battery packs may create a risk of injury and fire.

c. 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.
d. 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.
6) SERVICE
a. 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.
ENVIRONMENTAL PROTECTION
Recycle unwanted materials instead of disposing of them as waste. All tools,
accessories and packaging should be sorted, taken to a recycling centre
and disposed of in a manner which is compatible with the environment.
SAFETY INSTRUCTIONS FOR ALL SAWS
a. Keep hands away from cutting area and the blade. Keep your second hand on
the auxiliary handle, or motor housing. If both hands are holding the saw, they
cannot be cut by the blade.
b. Do not reach underneath the workpiece. The guard cannot protect you from the
blade below the workpiece.
c. 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.
d. Never hold the 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
minimise body exposure, blade binding, or loss of control.
e. Hold the power tool by insulated gripping surfaces when performing an
operation. Contact with a ”live” wire will also make exposed metal parts of the
power tool ”live” and shock the operator.
f. Always use blades with the correct size and shape of arbor holes. Blades that do
not match the mounting hardware of the saw will run eccentrically, causing loss
of control.
g. 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.
h. Do not operate the saw if the guard is damaged or does not operate correctly.
i. Never use the saw with the guard removed.

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 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.
a. 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.
b. When the 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.
c. When restarting a saw in the workpiece, centre the saw blade in the kerf and
check that saw teeth are not engaged with the material. If the blade is binding,
it may walk up or kickback from the workpiece as the saw is restarted.
d. Support large panels to minimise the risk of blade pinching and kickback. Large
panels tend to sag under their own weight. Supports must be placed under the
panel on both sides, near the line of cut and near the edge of the panel.
e. Blade depth and bevel adjusting locking screws must be tight and secure before
making a cut. If blade adjustment shifts while cutting, it may cause binding and
kickback.
f. Use extra caution when making a “plunge cut” into existing walls or other blind
areas. The protruding blade may cut objects that can cause kickback.
CIRCULAR SAW BLADE SAFETY WARNINGS
a. The maximum speed marked on the tool shall not exceed the maximum speed
marked on the blade.
b. Cracked circular saw blades shall be scrapped (repairing is not permitted).
Composite (tipped) circular saw blades, where the tip dimension is reduced to
less than 1 mm, shall be taken out of service.
c. Fastening screws and nuts shall be tightened using the tools supplied.
d. Clamping surfaces shall be cleaned to remove dirt, grease, oil and water.
e. Do not use loose rings or bushes to "make up" bore sizes on circular saw blades.
