3. personal safety  
must be NIOSH-approved for the specific  
hazards in the work area.  
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.  
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.  
b.use safety equipment. Always wear  
eye protection. Safety equipment such  
as a dust mask, non-skid safety shoes,  
a hard hat, or hearing protection used  
for appropriate conditions will reduce  
personal injuries.  
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.  
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.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.  
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.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.  
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.  
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.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  
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

this power tool. Failure to follow all  
instructions listed below may result in  
electric shock, fire and/or serious injury.  
5. Battery tool use and care  
2. Do not use accessories which  
are not specifically designed  
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.  
and recommended by the tool  
manufacturer. Just because the  
accessory can be attached to your power  
tool, it does not assure safe operation.  
b.Use power tools only with specifically  
designated battery packs. Use of any  
other battery packs may create a risk of  
injury and fire.  
3. The rated speed of the accessory  
must be at least equal to the  
maximum speed marked on the power  
tool. Accessories running faster than  
their RATED SPEED can break and fly  
apart.  
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.  
4. The outside diameter and the  
thickness of your accessory must  
be within the capacity rating of  
your power tool. Incorrectly sized  
accessories cannot be adequately  
guarded or controlled.  
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.  
5. The shank of the accessories must  
properly fit the Collet of the power  
tool. Accessories with arbor holes that  
do not match the mounting hardware of  
the power tool will run out of balance,  
vibrate excessively and may cause loss  
of control.  
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.  
6. Do not use a damaged accessory.  
Before each use inspect the  
accessory such as abrasive wheels  
for chips and cracks, backing pad for  
cracks, tear or excess wear. If power  
tool or accessory is dropped, inspect  
for damage or install an undamaged  
accessory. After inspecting and  
installing an accessory, position  
yourself and bystanders away from  
the plane of the rotating accessory  
and run the power tool at maximum  
no-load speed for one minute.
