SAFETY PRECAUTIONS

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 JIGSAW.

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.

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. 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.

d. 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.

KICKBACK

Kickback is a sudden reaction to a pinched or misaligned saw blade which causes the
saw to lift up and out of the workpiece.

When the blade is pinched or bound tightly by the kerf closing down, the blade stalls
and the motor reaction moves the unit back quickly towards 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 of the workpiece causing the blade to climb out of the kerf
and jump back towards the operator. Kickback is the result of misuse or incorrect
operating procedures and can be prevented by taking the following precautions:

a. Hold the saw tightly and position your arms to resist kickback forces. Position your

body to one side of the blade.

b. If the blade starts to bind, or when interrupting a cut, release the trigger and hold

the saw still in the material until the blade comes to a full stop. Do not attempt to
remove the saw from the work or pull the saw backward while the blade is
moving or kickback can 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

make sure that saw teeth do not touch the material. If the blade is binding, it
can 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 put below the
panel on both sides, near the line of cut and near the edge of the panel.

e. 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.

avoid stress on the blade.

WOOD

• Check that any previously used timber being sawn does not contain

any nails or other metal objects which would damage the blade.

METAL

• Choose a suitable blade for cutting metal

• Lubricate the material and blade with cutting oil to prevent

overheating.

HOLE CUTTING

• When starting a cut from the center of a work piece, drill a 12mm

diameter hole to ensure that there is clearance for the blade

• Remember that the blade should emerge from the workpiece at

every point of the cut.

• When cutting tight curves, reduce the forward speed of the saw.
