SERVICE

Tool  service  must  be  performed  only  by  qualified
repair personnel. 

Service or maintenance performed by 

unqualified personnel may result in a risk of injury.

GENERAL SAFETY RULES

When servicing a tool, use only identical replacement 
parts. Follow instructions in the Maintenance section 
of this manual.

 Use of unauthorized parts or failure to

follow  Maintenance  Instructions  may  create  a  risk  of 
shock or injury.

SPECIFIC SAFETY RULES

Hold  tool  by  insulated  gripping  surfaces  when
performing an operation where the cutting tool may
contact hidden wiring. 

Contact  with  a  “live”  wire  will 

also  make  exposed  metal  parts  of  the  tool  “live”  and 
shock the operator.

Know your power tool. Read operator’s manual care-
fully.  Learn  its  applications  and  limitations,  as  well 
as the specific potential hazards related to this tool. 

Following this rule will reduce the risk of electric shock, 
fire, or serious injury.

Always  wear  safety  glasses  with  side  shields.

Everyday glasses have only impact resistant lenses. They 
are NOT safety glasses. Following this rule will reduce 
the risk of eye injury.

Protect your lungs. Wear a face or dust mask if the 
operation is dusty. 

Following this rule will reduce the 

risk of serious personal injury.

Protect your hearing. Wear hearing protection during 
extended periods of operation.

 Following this rule will 

reduce the risk of serious personal injury.

Battery  tools  do  not  have  to  be  plugged  into  an
electrical  outlet;  therefore,  they  are  always  in
operating  condition.  Be  aware  of  possible  hazards 
when not using your battery tool or when changing 
accessories. 

Following this rule will reduce the risk of 

electric shock, fire, or serious personal injury.

Do  not  place  battery  tools  or  their  batteries  near 
fire or heat. 

This will reduce the risk of explosion and

possibly injury.

n

  

Never  use  a  battery  that  has  been  dropped  or
received a sharp blow.

 A damaged battery is subject to 

explosion.  Properly dispose of a dropped or damaged 
battery immediately.

Batteries vent hydrogen gas and can explode in the 
presence of a source of ignition, such as a pilot light. 

To reduce the risk of serious personal injury, never use 
any cordless product in the presence of open flame. An 
exploded  battery  can  propel  debris  and  chemicals.  If 
exposed, flush with water immediately.

Do  not  charge  battery  tool  in  a  damp  or  wet
location. 

Following this rule will reduce the risk of electric 

shock.

For best results, your battery tool should be charged 
in  a  location  where  the  temperature  is  more  than 
50°F but less than 100°F. Do not store outside or in 
vehicles.

Under  extreme  usage  or  temperature  conditions,
battery leakage may occur. If liquid comes in contact 
with your skin, wash immediately with soap and water, 
then neutralize with lemon juice or vinegar. If liquid 
gets into your eyes, flush them with clean water for 
at  least  10  minutes,  then  seek  immediate  medical
attention. 

Following this rule will reduce the risk of seri-

ous personal injury.

Save these instructions. 

Refer to them frequently and 

use them to instruct others who may use this tool. If you 
loan  someone  this  tool,  loan  them  these  instructions 
also.
