ence or knowledge, unless such persons are su-
pervised or trained to operate the product by 
a person responsible for their safety. Children 
should be supervised to ensure they do not use 
the devices as toys.

TOOL USE AND CARE

Do not force the power tool. Use the correct 
tool for the application.
 The correct tool will 
do the job better and more safely at the rate 
that it was designed to work at.
Do not use tools if switch does not turn it on 
or off.
 Any tool that cannot be controlled with 
the switch is dangerous and must be repaired.
Disconnect the plug from the power source 
before making any adjustments, changing ac-
cessories or storing the tool.
 This preventive 
safety measures reduce the risk of accidental 
starting of the tool.
When the power tool is not in use, store it out 
of the reach of children, and do not allow in-
dividuals who are not familiar with the power 
tool or these instructions to operate it.
 Power 
tools are dangerous in the hands on untrained 
users.
Maintain the power tool. Check for misalign-
ment or binding of moving parts, broken parts, 
and any other condition that may affect the 
operation of the power tool. 
If it is damaged, 
have it repaired before using. Many accidents 
are caused by poorly maintained power tools.
Check for misalignment or bonding of moving 
parts, breakage parts, and any other condition 
that may affect the tools operation.
 If you find 
a damaged tool, take it to service before use it. 
Use only accessories that are recommended by 
the manufacturer of your model.
 Suitable ac-
cessories for one tool, may become hazardous 
when are used on another tool.
Keep cutting tools, sharpened and clean. Cut-
ting tools in good condition with sharpened 
edges, are less likely to stuck in workpieces or 
easier to control.
Is recommendable to use a safety device suit-
able, such a thermal and differential switch 
when you are using an electric equipment.

SERVICE

Tool service must be performed only by quali-
fied repair personnel. Service or maintenance 
performed by unqualified personnel could re-
sult in a risk of injury.

SPECIFIC SAFETY RULES FOR 

HAMMER DRILLS

• Hold the tool by its insulated gripping sur-
faces when performing any operation where 
the tool may contact hidden wiring or its own 
cord.
 Contact with a “live” wire will make ex-
posed metal parts of the tool “live”, and shock 
the operator.
• Only use accessories that are in optimal con-
dition.
• Check that there is sufficient clearance for 
the drill bit under the workpiece before drill-
ing.
• Before plugging the tool in, check that the 
trigger lock-on button is “OFF”.
• When starting the hammer drill, let the drill 
run for a few seconds before using it on a 
workpiece. Watch for vibration or wobbling 
that could indicate poor installation of an ac-
cessory.
• If possible, always use clamps or a vise to hold 
the work.
• Always switch the drill OFF before putting it 
down.
• Ensure that the lighting is adequate to see 
the operation.
• Do not put pressure on the drill to the ex-
tent that it slows down the motor. For better 
results, and to lengthen the life of the drill, al-
low the drill bit to cut without pressure.
• Keep the work area free of tripping hazards.
• Secure the material that is being drilled. Nev-
er hold it in your hand or across your hand or 
across your legs.
• Do not use damaged or bowed drill bits.
• Keep hands away from rotating parts.
• Always wear safety goggles and a dust mask 
when drilling, especially when drilling above 
the level of your head.
• Watch out for flying sparks. Hold the tool so 
that any sparks will fly away from the operator 
and other persons. Keep all flammable materi-
als away when using this drill.
• Do not touch the workpiece immediately 
after operation. It may be extremely hot, and 
could burn the skin.
