Your tool uses a D

E

WALT charger. Be sure to read all safety instructions before using your 

charger. Consult the chart at the end of this manual for compatibility of chargers and battery 
packs.

  1. Plug the charger into an appropriate outlet before inserting the battery pack. 
  2. Insert the battery pack (F) into the charger, as shown in Figure 2, making sure the pack 

is fully seated in charger. The red (charging) light will blink continuously, indicating that the 
charging process has started. 

  3. The completion of charge will be indicated by the red light remaining ON continuously. The 

pack is fully charged and may be used at this time or left in the charger.

This charger is designed to detect certain problems that can arise. Problems are indicated by 
the red light flashing at a fast rate. If this occurs, re-insert the battery pack into the charger. If 
the problem persists, try a different battery pack to determine if the charger is working properly. 
If the new pack charges correctly, then the original pack is defective and should be returned 
to a service center or other collection site for recycling. If the new battery pack elicits the same 
trouble indication as the original, have the charger and the battery pack tested at an authorized 
service center. 

HOT/COLD DELAY
This charger has a hot/cold delay feature: when the charger detects a battery that is hot, it 
automatically starts a delay, suspending charging until the battery has cooled. After the battery 
has cooled, the charger automatically switches to the pack charging mode. This feature ensures 
maximum battery life. The red light flashes long, then short while in the hot/cold delay mode. 

LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the charge indicator showing Pack 
Charged.

WEAK BATTERY PACKS: Weak batteries will continue to function but should not be 
expected to perform as much work. 

FAULTY BATTERY PACKS: This charger will not charge a faulty battery pack. The charger will 
indicate faulty battery pack by refusing to light or by displaying problem pack or charger. 
NOTE: This could also mean a problem with a charger.

PROBLEM POWER LINE
Some chargers have a problem powerline indicator. When the charger is used with some 
portable power sources such as generators or sources that convert DC to AC, the charger may 
temporarily suspend operation, flashing the red light with two fast blinks followed by a pause. 
This indicates the power source is out of limits.

 1.  Longest life and best performance can be obtained if the battery pack is charged when the 

air temperature is between 65 °F and 75 °F (18 ° – 24 °C). DO NOT charge the battery pack 
in an air temperature below +40 °F (+4.5 °C), or above +105 °F (+40.5 °C). This is important 
and will prevent serious damage to the battery pack.

 2.  The charger and battery pack may become warm to the touch while charging. This is a 

normal condition, and does not indicate a problem. To facilitate the cooling of the battery 
pack after use, avoid placing the charger or battery pack in a warm environment such as in 
a metal shed or an uninsulated trailer.

 3.  A cold battery pack will charge at about half the rate of a warm battery pack. The battery 

pack will charge at that slower rate throughout the entire charging cycle and will not return 
to maximum charge rate even if the battery pack warms.

 4.  If the battery pack does not charge properly:
  

a. 

 

Check operation of receptacle by plugging in a lamp or other appliance;

  

b. 

 

Check to see if receptacle is connected to a light switch which turns power off when you 
turn out the lights; 

  

c. 

 

Move the charger and battery pack to a location where the surrounding air temperature 
is  approximately  65 °F – 75 °F  (18 ° – 24 °C); 

  

d. 

 

If charging problems persist, take the tool, battery pack and charger to your local service 
center.

 5.  The battery pack should be recharged when it fails to produce sufficient power on jobs 

which were easily done previously. DO NOT CONTINUE to use under these conditions. 
Follow the charging procedure. You may also charge a partially used pack whenever you 
desire with no adverse effect on the battery pack.

 6.  Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal 

chips, steel wool, aluminum foil, or any buildup of metallic particles should be kept away 
from charger cavities. Always unplug the charger from the power supply when there is no 
battery pack in the cavity. Unplug the charger before attempting to clean.

 7.  Do not freeze or immerse the charger in water or any other liquid.

 1.  The best storage place is one that is cool and dry, away from direct sunlight and excess 

heat or cold.

 2.  For long storage, it is recommended to store a fully charged battery pack in a cool dry place 

out of the charger for optimal results.

NOTE: Battery packs should not be stored completely depleted of charge. The battery pack 
will need to be recharged before use.

LOCK-OFF BUTTON AND TRIGGER SWITCH
Your saw is equipped with a lock-off button (B). 
To lock the trigger switch, press the lock-off button as shown in Figure 3. Always lock the 
trigger switch (A) when carrying or storing the tool to eliminate unintentional starting. The lock-
off button is colored red to indicate when the switch is in its unlocked position.
To unlock the trigger switch, press the lock-off button as shown in Figure 3. Pull the trigger 
switch to turn the motor ON. Releasing the trigger switch turns the motor OFF.

depressed the higher the speed of the saw. 

removing the battery pack. Depressing the battery release button without removing the battery 
pack can result in the battery pack falling out unexpectedly.
NOTE: For best results, make sure your battery pack is fully charged. 
To install the battery pack (F) into the tool handle, align the battery pack with the rails inside the 
tool’s handle and slide it into the handle until the battery pack is firmly seated in the tool and 
ensure that it does not disengage.
To remove the battery pack from the tool, press the release button (G) and firmly pull the battery 
pack out of the tool handle. Insert it into the charger as described in the charger section of this 
manual.

FUEL GAUGE BATTERY PACKS (FIG. 4A)
Some D

E

WALT battery packs include a fuel gauge which consists of three green LED lights that 

indicate the level of charge remaining in the battery pack. 
To actuate the fuel gauge, press and hold the fuel gauge button (H). A combination of the three 
green LED lights will illuminate designating the level of charge left. When the level of charge in 
the battery is below the usable limit, the fuel gauge will not illuminate and the battery will need 
to be recharged.
NOTE:  The fuel gauge is only an indication of the charge left on the battery pack. It does 
not indicate tool functionality and is subject to variation based on product components, 
temperature and end-user application.
For more information regarding fuel gauge battery packs, please call 1-800-4-D

tool from power source before making any adjustments or removing/installing 
attachments or accessories. An accidental start-up can cause injury.
Different blade lengths are available. Use the appropriate blade for the application. The blade 
should be longer than 3-1/2" (89 mm) and should extend past the shoe and the thickness of 
the workpiece during the cut. Do not use jigsaw blades with this tool.

TO INSTALL BLADE INTO SAW
 1.  Pull blade clamp release lever (C) up (Fig. 6).
 2.  Insert blade shank from the front.
 3.  Push blade clamp release lever down.
NOTE: The blade can be installed in the DCS380 in four positions as shown in Figure 7. The 
blade can be installed in the DCS381 in two positions as shown in Figure 7. Both units allow 
the blade to be installed upside-down to assist in flush-to cutting; see Figure 11.

blade may result in personal injury.
 1.  Open up blade clamp release lever.
 2.  Remove blade.

Your DCS380 is equipped with a horizontal blade clamp. Installing a blade in the horizontal 
orientation allows cutting close to floors, walls or ceilings where limited clearance is available. 
Ensure that the shoe is pressed against the framing to avoid kickback.

Your DCS380 comes with an adjustable shoe. The shoe will adjust to limit the depth of cut. 
Hold the saw with the underside facing up. Push the button on the hand grip and slide the shoe 
out to one of the three settings and release the button.
The DCS381 comes with a fixed shoe that is not adjustable.
