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 tools may result in serious personal injury.

b)

 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.

c)

 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 energizing 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 jewelry. 

Keep your hair, clothing and gloves away from moving 
parts. 

Loose clothes, jewelry or long hair can be caught in 

moving parts. 

g)

 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.

4) POWER TOOL USE AND CARE

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.

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. 

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.

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, 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.

5) BATTERY TOOL USE AND CARE

a) 

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.

b)

  Use power tools only with specifically designated battery 

packs. 

Use of any other battery packs may create a risk of 

injury and fire.
