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.
Save all warnings and
instructions for future reference.
The term "power tool" in the warnings refers to your
mains-operated (corded) power tool or battery-operated
(cordless) power tool.
Work area safety
1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
2. 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.
3. Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical Safety
4. 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.
5. 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.
6. Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
7. 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.
8. 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.
9. If operating a power tool in a damp location is
unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of an
GFCI reduces the risk of electric shock.
Personal Safety
10. 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.
11. 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.
12. 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.

3
13. 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.
14. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
15. 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.
16. 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.
Power tool use and care
17. 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.
18. 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.
19. 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.
20. 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.
21. 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.
22. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
23. 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.
Battery tool use and care
24. 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.
25. Use power tools only with specifically
designated battery packs. Use of any other
battery packs may create a risk of injury and fire.
26. 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.
27. 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.
Service
28. 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.
29. Follow instruction for lubricating and
changing accessories.
30. Keep handles dry, clean and free from oil and
grease.

Consignes de sécurité générales
pour outils électriques
MISE EN GARDE Veuillez lire toutes les mises
en garde de sécurité et toutes les instructions.
L'ignorance des mises en garde et des instructions
comporte un risque de choc électrique, d'incendie et/ou
de blessure grave.
Conservez toutes les mises en
garde et instructions pour
référence future.
Le terme  outil électrique  qui figure dans les
avertissements fait référence à un outil électrique
branché sur une prise de courant (par un cordon
d'alimentation) ou alimenté par batterie (sans fil).
Sécurité de la zone de travail
1. Maintenez la zone de travail propre et bien
éclairée. Les zones de travail encombrées ou
sombres ouvrent grande la porte aux accidents.
2. N'utilisez pas les outils électriques dans les
atmosphères explosives, par exemple en
présence de liquides, gaz ou poussières
inflammables. Les outils électriques produisent
des étincelles au contact desquelles la poussière
ou les vapeurs peuvent s'enflammer.
3. Assurez-vous qu'aucun enfant ou curieux ne
s'approche pendant que vous utilisez un outil
électrique. Vous risquez de perdre la maîtrise de
l'outil si votre attention est détournée.
Sécurité en matière d'électricité
4.
Les fiches d'outil électrique sont conçues pour
s'adapter parfaitement aux prises de courant. Ne
modifiez jamais la fiche de quelque façon que ce
soit. N'utilisez aucun adaptateur de fiche sur les
outils électriques avec mise à la terre.
En ne
modifiant pas les fiches et en les insérant dans des
prises de courant pour lesquelles elles ont été
conçues vous réduirez les risques de choc électrique.
5. Évitez tout contact corporel avec les surfaces
mises à la terre, telles que les tuyaux,
radiateurs, cuisinières et réfrigérateurs. Le
risque de choc électrique est plus élevé si votre
corps se trouve mis à la terre.
6. N'exposez pas les outils électriques à la pluie
ou à l'eau. La présence d'eau dans un outil
électrique augmente le risque de choc électrique.
7. Ne maltraitez pas le cordon. N'utilisez jamais
le cordon pour transporter, tirer ou
débrancher l'outil électrique. Maintenez le
cordon à l'écart des sources de chaleur, de
l'huile, des objets à bords tranchants et des
pièces en mouvement. Le risque de choc
électrique est plus élevé lorsque les cordons sont
endommagés ou enchevêtrés.
8.
Lorsque vous utilisez un outil électrique à
l'extérieur, utilisez un cordon prolongateur prévu à
cette fin.
Les risques de choc électrique sont moindres
lorsqu'un cordon conçu pour l'extérieur est utilisé.
9. Si vous devez utiliser un outil électrique dans
un endroit humide, utilisez une source
d'alimentation protégée par un disjoncteur de
fuite à la terre. L'utilisation d'un disjoncteur de
fuite à la terre réduit le risque de choc électrique.
