ADVERTENCIA: 
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 toolsmay 
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 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. Air vents often cover moving parts and should also be avoided.

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
E
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.
If you have questions or comments, contact us.
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. 
Pour toute question ou tout commentaire, nous contacter.
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 
1-800-4-D
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 and in the manner intended for the particular type of power tool, taking 
into account the working conditions and the work to be performed.

•  Hold power tools by insulated gripping surfaces when performing an operation 
where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” 
wire will make exposed metal parts of the tool “live” and shock the operator.

 
•  Use clamps or other practical way to secure and support the workpiece to a stable 

platform. Holding the work by hand or against your body is unstable and may lead to loss 
of control.
