Fuel Gauge Battery Packs
Some DeWALT battery packs include a fuel gauge which
consists of three green LED lights that indicate the level of
charge remaining in the batterypack.
To actuate the fuel gauge, press and hold the fuel gauge
button

. 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 berecharged.
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-userapplication.
Side Handle (Fig.A)
WARNING: To reduce the risk of personal injury, ALWAYS
operate the tool with the side handle properly installed.
Failure to do so may result in the side handle slipping
during tool operation and subsequent loss of control. Hold

sidehandle.
2. Move the depth rod
11
so the distance between the
end of the rod and the end of the bit equals the desired
drillingdepth.
3. Release the button to lock rod into position. When drilling
with the depth rod, stop when end of rod reaches surface
ofmaterial.
Utility Hook (Fig.A,D)
A utility hook
14
is fitted below the main handle

Bit and Bit Holder
WARNING: Burn Hazard. ALWAYS wear gloves when
changing bits. Accessible metal parts on the tool and bits
may get extremely hot during operation. Small bits of
broken material may damage barehands.
The hammerdrill can be fitted with different bits depending on
the desired application. Use sharp drill bitsonly.
Bit Reccomendations
• For wood, use twist bits, spade bits, power auger bits or
holesaws.
• For metal, use high-speed steel twist drill bits or holesaws.
Use a cutting lubricant when drilling metals. The exceptions
are cast iron and brass which should be drilleddry.
• For masonry, such as brick, cement, cinder block, etc., use
carbide-tipped bits rated for percussiondrilling.
SDS-Plus Bit Holder (Fig. F)
NOTE: Special adapters are needed to use the SDS-plus tool
holder with straight shank bits and hexagonal screwdriver bits.
Refer to OptionalAccessories.
To insert a drill bit or other accessory:
1. Insert the shank of the bit about 19mm into SDS-Plus
toolholder.
2. Push and rotate bit until it locks in place. The bit will be
securelyheld.
3. To release bit, pull the sleeve
10

Keyless Chuck (Fig. F, G)
DCH334
On some models, a keyless chuck can be installed in place of the
SDS-Plus bitholder.
WARNING: Never use standard chucks in the rotary
hammeringmode.
Replacing the SDS-Plus Bit Holder with the Keyless Chuck
1. Select hammering only mode (see Operation Modes), this
locks the spindle to prevent it from rotating when unlocking
the removable toolholder.
2. Turn the locking collar
15
into the unlocked position and
pull the installed bit holderoff.
3. Push the keyless chuck
16
onto the spindle
17
and turn
the locking collar into the lockingposition.
4. To replace the keyless chuck with the SDS-Plus bit holder,
first remove the keyless chuck the same way as the SDS-
Plus bit holder was removed. Then replace the SDS-Plus
bitholder the same way as the keyless chuck wasreplaced.
