The warnings, precautions, and instructions 
discussed in this instruction manual cannot

that may occur.  

It must be understood by the 

operator that common sense and caution are 
factors which cannot be built into this product, 
but must be supplied by the operator.

Power Tool Use and Care

1. 

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.

2. 

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.

3. 

Disconnect the plug from the power source and/
or remove the battery pack, if detachable, 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.

4. 

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.

5. 

Maintain power tools and accessories. 
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.

6. 

Keep cutting tools sharp and clean.  

Properly 

maintained cutting tools with sharp cutting edges 
are less likely to bind and are easier to control.

7. 

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.

8. 

Keep handles and grasping surfaces dry, clean 
and free from oil and grease.  

Slippery handles 

and grasping surfaces do not allow for safe handling 
and control of the tool in unexpected situations.

Battery Tool Use and Care

1. 

Prevent unintentional starting. 

Ensure the 

switch is in the off-position before connecting 
to battery pack, picking up or carrying the 
power tool. Carrying the power tool with your 
finger on the switch or energizing power tool 
that have the switch on invites accidents.

2. 

Disconnect the battery pack from the 
power tool before making any adjustments, 
changing accessories, or storing power tool. 

Such preventive safety measures reduce the 
risk of starting the power tool accidentally.

3. 

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.

4. 

Use power tools only with specifically 
designated battery packs. 

Use of any other 

battery packs may create a risk of injury and fire.

5. 

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.

6. 

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.

7. 

Do not use a battery pack or power tool that 
is damaged or modified. 

Damaged or modified 

batteries may exhibit unpredictable behavior 
resulting in fire, explosion or risk of injury.

8. 

Do not expose a battery pack or power tool to 
fire or excessive temperature. 

Exposure to fire or 

temperature above 265°F may cause explosion.

9. 

Follow all charging instructions and do 
not charge the battery pack or power tool 
outside of the temperature range specified 
in the instructions. 

Charging improperly or at 

temperatures outside of the specified range may 
damage the battery and increase the risk of fire.

10. 

Have servicing performed by a qualified 
repair person using only identical 
replacement parts. 

This will ensure that 

the safety of the product is maintained.

11. 

Do not modify or attempt to repair the power 
tool or the battery pack except as indicated 
in the instructions for use and care.
