The automatic Tune-Up™ Mode equalizes or balances the individual cells in the battery pack 
allowing it to function at peak capacity. Battery packs should be tuned up weekly or after 10 
charge/discharge cycles or whenever the pack no longer delivers the same amount of work. To 
use the automatic Tune-Up™, place the battery pack in the charger and leave it for at least 8 
hours. The charger will cycle through the following modes.
  1. The red light will blink continuously indicating that the 1-hour charge cycle has started.
  2. When the 1-hour charge cycle is complete, the light will stay on continuously and will no 

longer blink. This indicates that the pack is fully charged and can be used at this time. 

  3. If the pack is left in the charger after the initial 1-hour charge, the charger will begin the 

Automatic Tune-Up mode. This mode continues up to 8 hours or until the individual cells in 
the battery pack are equalized. The battery pack is ready for use and can be removed at any 
time during the Tune-Up mode.

 4. Once the Automatic Tune Up mode is complete, the charger will begin a maintenance 

charge; the red indicator will remain lit.

WALT 7.2, 9.6, 12, 14.4, 18 Volt 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.

conductive objects. Danger of electric shock or electrocution. 
  1. Plug the charger into an appropriate outlet before inserting battery pack. 
 2. Insert the battery pack into the 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.

Some chargers are designed to detect certain problems that can arise with battery packs. 
Problems are indicated by the red light flashing at a fast rate. If this occurs, re-insert battery pack 
into the charger. If the problem persists, try a different battery pack to determine if the charger is 
OK. 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 tested at an authorized service center.

HOT/COLD PACK DELAY
Some chargers have a Hot/Cold Pack Delay feature: when the charger detects a battery that is 
hot, it automatically starts a Hot Pack 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 
Pack Delay mode. 

PROBLEM POWER LINE
Some chargers have a Problem Power Line 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.

LEAVING THE BATTERY PACK IN THE CHARGER
The charger and battery pack can be left connected with the red light glowing indefinitely. The 
charger will keep the battery pack fresh and fully charged. 
NOTE: A battery pack will slowly lose its charge when kept out of the charger. If the battery pack 
has not been kept on maintenance charge, it may need to be recharged before use. A battery 
pack may also slowly lose its charge if left in a charger that is not plugged into an appropriate 
AC source.
WEAK BATTERY PACKS: Chargers can also detect a weak battery pack. Such batteries are 
still usable but should not be expected to perform as much work. The charger will indicate to 
replace battery pack.

  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 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. If the battery pack does not charge properly:
  

a. 

 

Check current at 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 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.

  4.  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 affect on the battery pack.

 5. Under certain conditions, with the charger plugged into the power supply, the exposed 

charging contacts inside the charger can be shorted by foreign material. Foreign materials 
of a conductive nature such as, but not limited to, 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 charger before 
attempting to clean.

  6. Do not freeze or immerse 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.  Long storage will not harm the battery pack or charger. Under proper conditions, they can be 

stored for 5 years or more.

To turn the tool on, squeeze the trigger switch (A). To turn the tool off, release the trigger switch. 
Your tool is equipped with a brake. The chuck will stop as soon as the trigger switch is fully 
released. 
NOTE: Continuous use in variable speed range is not recommended. It may damage the switch 
and should be avoided.

A forward/reverse control button (B) determines the direction the tool will spin and also serves 
as a lock-off button. 
To select forward rotation, release the trigger switch and depress the for ward/re verse control 
button on the right side of the tool.
To select reverse, depress the forward/reverse control button on the left side of the tool. 
The center position of the control button locks the tool in the OFF position. When changing the 
position of the control button, be sure the trigger is released. 
NOTE: The first time the tool is run after changing the direction of rotation, you may hear a click 
on start up. This is normal and does not indicate a problem. 

Your drill is equipped with a separate mode control collar (Fig. 1, C) to switch between drilling, 
screwdriving and hammerdrilling mode. 

SCREWDRIVING (FIG. 2)
  1. Select the desired speed/torque range using the three-speed gear shifter (E) on the top of 

tool to match the speed and torque to the planned application. To set the torque level to the 
proper setting on the clutch collar, initially set the clutch collar at a lower setting to ensure 
the fastener to be set to your specification. 

    NOTE: Use the lowest torque setting required to seat the fastener at the desired depth. The 

lower the number, the lower the torque output.

  2. Rotate the mode control collar (C) so the screw symbol is aligned with the arrow. 
 3. Set the torque adjustment collar (D) to the appropriate number setting for the torque 

desired.

    NOTE: The torque adjustment collar may be set on any number and change between screw-

driving and drilling modes using the mode control collar. 

regardless of the position of the torque adjustment collar (D).
Rotate the mode control collar (C) so the drill symbol is aligned with the arrow.

NOTE: The torque adjustment collar (D) may be set on any number. 

HAMMERDRILLING (FIG. 4)
Rotate the mode control collar (C) so the hammer symbol is aligned with the arrow.

Your tool has an adjustable torque screwdriver mechanism for driving and removing a wide array 
of fastener shapes and sizes and a hammer mechanism for drilling into masonry. Circling the 
torque adjustment collar (D) are numbers. These numbers are used to set the clutch to deliver 
a torque range. The higher the number on the collar, the higher the torque and the larger the 
fastener which can be driven. To select any of the numbers, rotate until the desired number aligns 
with the arrow.

The three-speed feature of your tool allows you to shift gears for greater versatility. To select 
speed 1 (highest torque setting), turn the tool off and permit it to stop. Slide the gear shifter (E) 
all the way to the left. Speed 2 (middle torque and speed setting) is in the middle position. Speed 
3 (highest speed setting) is to the right. 
NOTE: Do not change gears when the tool is running. Always allow the drill to come to a com-
plete stop before changing gears. If you have trouble changing gears, make sure that the gear 
shifter is engaged in one of the three speed settings.

TO INSERT A DRILL BIT OR OTHER ACCESSORY
  1. Lock the trigger in the OFF position. 
  2. Grasp the chuck sleeve (F) with one hand and use the other hand to secure the tool as 

shown in Figure 5. Rotate the sleeve counterclockwise (viewed from the front) far enough to 
accept the desired accessory. 

  3. Insert the bit or other accessory about 3/4" (19 mm) into the chuck, as shown in Figure 6. 

Grasp the chuck sleeve securely and rotate the sleeve clockwise (viewed from the front) 
with one hand while using the other hand to secure the tool. Rotate the sleeve clockwise 
until sleeve cannot be rotated any further, as demonstrated in Figure 7. As the drill is being 
operated in the forward position, the chuck will continually self-tighten the jaws of the chuck 
onto the bit to maximize the bit gripping strength. 

To release the accessory, repeat Step 2.

NOTE: Make sure your battery pack is fully charged. 

switch actuation before removing or installing battery.
To install the battery pack into the tool handle, align the notch inside the tool’s handle with 
the battery pack and slide the battery pack firmly into the handle until you hear the lock snap 
into place as shown in Figure 8.
To remove the battery pack from the tool, press the release buttons (G) and firmly pull the 
battery pack out of the tool handle. Insert it into the charger (Fig. 9) as described in the charger 
section of this manual.

dle properly installed. Failure to do so may result in the side handle slipping during tool operation 
and subsequent loss of control. Hold tool with both hands to maximize control.
Side handle clamps to the front of the gear case as shown and may be

 

rotated to permit right- or left-hand use. Side handle must be tightened suf-
ficiently to resist the twisting action of the tool if the accessory binds or 
stalls. Be sure to grip the side handle at the far end to control the tool during 
a stall. 
If model is not equipped with side handle, grip drill with one hand on the 
handle and one hand on the battery pack.

  1. Select the desired speed/torque range using the gear shifter to match the speed and torque 

to the planned operation.

  2. For WOOD, use twist bits, spade bits, power auger bits or hole saws. For METAL, use high-

speed steel twist drill bits or hole saws. Use a cutting lubricant when drilling metals. The 
exceptions are cast iron and brass which should be drilled dry. 

  3. Always apply pressure in a straight line with the bit. Use enough pressure to keep the drill bit 

biting, but do not push hard enough to stall the motor or deflect the bit.

  4. Hold tool firmly with both hands to control the twisting action of the drill. 
 5. IF DRILL STALLS, it is usually because it is being overloaded. RELEASE TRIGGER 

IMMEDIATELY, remove drill bit from work, and determine cause of stalling. DO NOT CLICK 
TRIGGER OFF AND ON IN AN ATTEMPT TO START A STALLED DRILL – THIS CAN 
DAMAGE THE DRILL.

  6. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent 

jamming. 

  1. When drilling, use just enough force on the hammer to keep it from bouncing excessively or 

“rising” off the bit. Too much force will cause slower drilling speeds, overheating, and a lower 
drilling rate.

  2. Drill straight, keeping the bit at a right angle to the work. Do not exert side pressure on the 

bit when drilling as this will cause clogging of the bit flutes and a slower drilling speed.

  3. When drilling deep holes, if the hammer speed starts to drop off, pull the bit partially out of 

the hole with the tool still running to help clear debris from the hole.

  4. For MASONRY, use carbide-tipped bits or masonry bits. A smooth, even flow of dust indi-

cates the proper drilling rate.
