Fig. 3

WARNING:

Do not allow familiarity with your tool to make you 

careless. Remember that a careless fraction of a 

second is sufficient to inflict severe injury.

WARNING:

Always wear safety goggles or safety glasses with 

side shields when operating tools. Failure to do so 

could result in objects being thrown into your eyes 

resulting in possible serious injury.

WARNING:

Do  not  use  any  attachments  or  accessories 

not  recommended  by  the  manufacturer  of  this 

tool. The use of attachments or accessories not 

recommended can result in serious personal injury.

APPLICATIONS

You may use this tool for the purposes listed below:

Cutting  all  types  of  wood  products  (lumber,  plywood, 

paneling, composition board, and hard wood)

Cutting masonite and plastic

Cutting drywall

Cutting metals such as sheet steel, pipe, steel rods, alu-

minum, brass, and copper

CAUTION:

If at any point during the charging process none 

of the LEDs are lit, remove the battery pack from 

the charger to avoid damaging the product. DO 

NOT insert another battery. Return the charger and 

battery to your nearest service center for service 

or replacement.

CHARGING THE BATTERY PACK

The  battery  pack  for  this  tool  has  been  shipped  in  a  low 
charge condition to prevent possible problems. Therefore, 
you should charge it until the light on front of charger changes 
from flashing green to continuous green.

NOTE:

 Batteries will not reach full charge the first time they 

are  charged.  Allow  several  cycles  (operation  followed  by 
recharging) for them to become fully charged. This is normal 
for nickel-cadmium batteries.

TO CHARGE

See Figure 3.

Charge the battery pack only with the charger provided.

Make sure the power supply is normal house voltage, 
120 volts, 60 Hz, AC only.

n

  Connect the charger to a power supply.

n

  Attach the battery pack to the charger by aligning the 

raised ribs on the battery pack with the grooves in the 
charger, then slide the battery pack onto the charger. 

n

  After  normal  usage,  30  minutes  of  charging  time  is

required to be fully charged. 

n

  The battery pack will become slightly warm to the touch 

while charging. This is normal and does not indicate a 
problem.

n

  Do not place the charger in an area of extreme heat or 

cold. It will work best at normal room temperature.

n

  When  the  batteries  become  fully  charged,  unplug  the  

charger from the power supply and remove the battery 
pack.

IMPORTANT  INFORMATION  FOR  RECHARG-
ING A HOT BATTERY PACK

When  using  the  tool  continuously,  the  batteries  in  the
battery  pack  will  become  hot.  You  should  let  a  hot
battery pack cool down for approximately 20 minutes before
attempting  to  recharge.  When  the  battery  pack  becomes 
discharged and is hot, the green LED will be off and the red 
LED will begin flashing. 
When the battery pack cools down to approximately 104°F 
(40°C),  the  charger  will  automatically  begin  fast  charge 
mode.
If the Red LED continues to flash for more than 90 minutes, 
and the green LED remains off, this may indicate a damaged 
battery that will not charge.

IMPORTANT  INFORMATION  FOR  RECHARG-
ING A COOL BATTERY PACK

If the battery pack is below normal temperature range, the 
red LED will begin flashing and the green LED will be off. 
When the battery warms to a temperature of more than 41°F 
(5°C), the charger will automatically begin fast charge mode.

NOTE: 

Refer  to 

“CHARGING  THE  BATTERY  PACK”

  for

normal recharging of batteries. If the charger does not charge 
your battery pack under normal circumstances, return both 
the battery pack and charger to your nearest repair center 
for electrical check. For the location of your nearest repair 

center, please call 1-866-539-1710.
