SAFETY INSTRUCTIONS
WARNING! Read all instructions.Failure to follow all instructions listed
below may result in electric shock, fire and/or serious injury.
SAVE THESE INSTRUCTIONS
1. Work area.
a. Keep work area clean and well lit. Cluttered and 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. Use a Residual Circuit Breaker on all 230V Power tools. This can help
minimise the risk of an electrical shock if an earth fault or short circuits occurs.
g. If using a power cable extension ensure that the cable is fully unwound
and that its length is less than 30m. Lengths over 30 m will effect the tools
performance as a result of voltage drop.
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 safety equipment. Always wear eye protection. Safety equipment
such as dust mask, non-skid safety shoes, hard hat, or hearing protection used
for appropriate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the off-position
before plugging in. Carrying power tools with your finger on the switch or
plugging in power tools that have the switch on invites accidents.
d. Remove any adjusting key or wrench before turning the power tool

7 CIRCULAR SAW BC185J
on. A wrench or a key left attached to a rotating part of 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 these devices 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 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 tools operation. If damaged, have the power tool repaired before
use. Poorly maintained power tools cause many accidents.
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 and in the manner intended for the particular type of
power tool, taking into account the working conditions and the work to
be performed. Use of the power tool for operations different from intended could
result in a hazardous situation.
5. 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.
HEALTH ADVICE
WARNING! When drilling, sanding, sawing or grinding, dust particles will be
produced. In some instances, depending on the materials you are working with,
this dust can be particularly harmful to you (e.g. lead from old gloss paint).
You are advised to consider the risks associated with the materials you are working
with and to reduce the risk of exposure. You should:
- Work in a well-ventilated area.

- Work with approved safety equipment, such as those dust masks that are specially
designed to filter microscopic particles.
ADDITIONAL SAFETY INSTRUCTIONS FOR YOUR CIRCULAR
SAW
1.If the supply cord is damaged have it replaced by a qualified person.
2.Do not use blades which are deformed or cracked.
3.Do not use saw blades made of high speed steel.
4.Do not use blades which do not comply with the characteristics specified in these
instructions.
5.Do not stop the blade by lateral pressure on the disc.
6.Ensure that movable guards operate freely without jamming.
7.Do not lock the guard in the open position.
8.Ensure that any-retraction mechanism of the guard system operates correctly.
9.Characteristics of saw blades. Take carful note of blade thickness & diameter and
ensure it is suitable for the circular saw.
10.Do not use saw blades, the body of which is thicker, or the set of which is smaller
than the thickness of the riving knife.
11.Ensure that the riving knife is adjusted so that the distance between the riving knife
and the toothed rim of the saw blade is not more than 5mm. The toothed rim does not
extend more than 5mm beyond the lower end of the riving knife. The riving knife should
always be used except when plunging in the middle of the work piece.
12.For circular saws for woodworking it is advised that if used in confined areas dust
protection or separate dust collection system should be used.
13. Always use the appropriate safety equipment that is required for the product. e.g.
Goggles / Safety Spectacles, Ear defenders (essential with tools with a noise rating of
over 85 dbA), Gloves and face masks. In all cases ensure that the safety equipment is
in good condition.
Double insulation:
The tool is double insulated. This means that all the external metal parts are electrically
insulated from the mains power supply. This is done by placing insulation barriers
between the electrical and mechanical components making it unnecessary for the tool
to be earthed.
Important note:
Ensure your mains supply voltage is the same as your tool rating plate voltage. Remove
the mains plug from socket before carrying out any adjustment or servicing.
