specified voltage may cause a serious injury to 
the user as well as damage the tool.

 IMPORTANT: This appliance is not intended 

for use by persons (including children) with re-
duced physical, sensory or mental capabilities 
may be different or reduced, or lack of experi-
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 

ANGLE GRINDERS

• Hold the machine by the isolated rubber 
parts when you are operating where the cut-
ting machine may be in contact with a hide 
wiring installation or its own cable. 
Contact with a ‘live’ wire can expose metal 
parts of the machine ‘alive’ and give you an 
electric shock.
• Always use an adequate blade guard protec-
tion. This guard provides protection to the 
user of the pieces that can be detached of the 
abrasive blade.  
• The abrasive discs should be used at the 
speed indicated on the warning machine label. 
Otherwise the discs or accessories that run on 
a different speed range can fly and cause in-
juries. 
• Remove all adjusting keys or wrenches before 
turning the power tool ‘on’. A wrench or a key 
that is left attached to a rotating part of the 
power tool may result in personal injury.
• Never leave the machine locked on the on 
position. Before to connect to the power sup-
ply, be sure that the switch is in the off posi-
tion.
• When start the machine leaves it run a few 
minutes without load before to use it on a 
work piece. Watch the vibration or undulation 
it may indicate you a poor installation.
• When operating the grinder, avoid the abra-
sive disc to bend or break. If this happens, stop 
the machine and renew the disc.
• Don’t use damaged discs.
• Don’t use worn discs. Worn discs can cause 
a disc explosion and cause serious personal in-
jury. A depressed center abrasive disc must not 
be used if worn below 3 inches of diameter.
• Use clamps or other practical means to sup-
port and secure the workpiece to a stable plat-
