GENERAL POWER TOOL SAFETY WARNINGS
WARNING! Read all safety warnings, instructions, illustrations and specications provided with
this power tool.
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.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
dust. Power tools create sparks which may ignite the dust or fumes.
Distractions can cause you to lose control.
2) Electrical safety
There is an increased risk of electric shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric
shock.
Damaged or entangled cords increase the risk of electric shock.
Use of a cord suitable
for outdoor use reduces the risk of electric shock.
supply. Use of an RCD reduces the risk of electric shock.
3) Personal safety
A moment of inattention
while operating power tools may result in serious personal injury.
Protective equipment such as dust mask, non-
skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
power tools that have the switch on invites accidents.
A wrench or a key left attached to a
rotating part of the power tool may result in personal injury.

safety principles. A careless action can cause severe injury within a fraction of a second.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your 3 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.
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 unfamiliar with the power tool or
these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
before use. Many accidents are caused by poorly maintained power tools.

The speed regulation wheel has eleven detents, the speed can be set speed between 4000 (position 1) and
10000 (position 6) RPM.
Tool Protections
The electronic protection protects the tool from different events that can damage the tool and create a risk
of injury for the operator.
• Temperature cut-out: In a case of overheating, the protection limits the tool power consumption and reduce
RPM. If the temperature continues to rise, the electronic protection turns off the tool and the LED starts
blinking.
