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.  
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  
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.  
moment of inattention while operating power  
tools may 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.  
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.  
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
