3. Personal safety  
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.  
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.  
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.  
b. Use personal protective 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.  
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.  
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.  
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.  
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.  
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.  
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.  
b. Use power tools only with specifically  
designated battery packs. Use of any other  
battery packs may create a risk of injury and fire.  
c. When battery pack is not in use, keep it away  
from other metal objects, like paper clips,  
coins, keys, nails, screws or other small metal  
objects, that can make a connection from  
one terminal to another. Shorting the battery  
terminals together may cause burns or a fire.  
g. If devices are provided for the connection of  
dust extraction and collection facilities, ensure  
these are connected and properly used. Use of  
these devices can reduce dust-related hazards.  
h. Only use safety equipment that has been  
approved by an appropriate standards agency.  
Unapproved safety equipment may not provide  
adequate protection. Eye protection must be ANSI-  
approved and breathing protection must be NIOSH-  
approved for the specific hazards in the work area.  
d. Under abusive conditions, liquid may be  
ejected from the battery; avoid contact.  
If contact accidentally occurs, flush with  
water. If liquid contacts eyes, additionally  
seek medical help. Liquid ejected from the  
battery may cause irritation or burns.  
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.  
6. Service  
a. Have your power tool serviced by a qualified  
repair person using only identical replacement  
parts. This will ensure that the safety of the power  
tool is maintained.  
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.
