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
c)Do not expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric
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.
WARNING: To reduce the risk of injury, read the instruction
General Power Tool Safety Warnings
WARNING! Read all safety warnings and all instructions
Failure to follow the warnings and instructions may result in
electric shock, fire and/or serious injury.

DANGER: Indicates an imminently hazardous situation
which, if not avoided, will result in death or serious injury.
WARNING: Indicates a potentially hazardous situation
which, if not avoided, could result in death or serious injury.
CAUTION: Indicates a potentially hazardous situation which,
if not avoided, may result in minor or moderate injury.
NOTICE: Indicates a practice not related to personal injury
which, if not avoided, may result in property damage.
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.
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 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 dust collection can
reduce dust-related hazards.
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.
Additional safety instructions for drills
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.
• Wear ear protectors. Exposure to noise can cause hearing
• Use auxiliary handles supplied with the tool. Loss of control
can cause personal injury.
• Hold power tool by insulated gripping surfaces only, when
performing an operation where the cutting accessory may
contact hidden wiring or its own cord. Cutting accessory
contacting a “live” wire may make exposed metal parts of the
power tool “live” and shock the operator.

WARNING: Some dust created by power sanding, sawing,
grinding, drilling, and other construction activities contains chemicals
known to cause cancer, birth defects or other reproductive harm.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry
products, and
• arsenic and chromium from chemically-treated lumber
Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed
to filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding,
sawing, grinding, drilling, and other construction activities.
Wear protective clothing and wash exposed areas with
soap and water. Allowing dust to get into your mouth, eyes, or
lay on the skin may promote absorption of harmful chemicals.
WARNING: Use of this tool can generate and/or disburse dust,
which may cause serious and permanent respiratory or other injury.
Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face
and body.
eyeglasses are NOT safety glasses. Also use face or dust mask if
cutting operation is dusty. All users and bystanders MUST ALWAYS
wear certified safety equipment:
ANSI Z87.1 eye protection (CAN/CSA Z94.3),
ANSI S12.6 (S3.19) hearing protection,

conditions and duration of use, noise from this product may
contribute to hearing loss.
• An extension cord must have adequate wire size (AWG
or American Wire Gauge) for safety. The smaller the gauge
number of the wire, the greater the capacity of the cable, that
is 16 gauge has more capacity than 18 gauge. An undersized
cord will cause a drop in line voltage resulting in loss of power
and overheating. When using more than one extension to make
up the total length, be sure each individual extension contains
at least the minimum wire size. The following table shows the
correct size to use depending on cord length and nameplate
ampere rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.
