22MM CORDLESS ROTARY HAMMER
WITH STOP ROTATION DW005
ADDITIONAL SAFETY RULES FOR ROTARY HAMMERS
• Hold tool by insulated gripping surfaces when performing an operation where
the cutting tool may contact hidden wiring or its own cord. Contact with a ‘live’
wire will make exposed metal parts of the tool ‘live’ and shock the operator.
• Wear safety goggles or other eye protection. Hammering and drilling operations
cause chips to fly. Flying particles can cause permanent eye damage.
• Wear ear protectors when hammering for extended periods of time. Temporary
hearing loss or serious ear drum damage may result from the high sound levels
generated by hammer drilling.
• Always use the side handle supplied with the tool. Keep a firm grip on the tool at
all times. Do not attempt to operate this tool without holding it with both hands.
• Do not overreach while operating the tool. Maintain a balanced working stance
at all times. When necessary, use only properly positioned, safe, platforms and
scaffolding. WORK SAFE.
• Hammer bits and tools get hot during operation. Wear gloves when touching
them.
• CAUTION: DO NOT TOUCH ANY METAL PARTS OF THE TOOL
when drilling or driving into walls, floors or wherever live electrical wires may
be encountered! Hold the tool only by insulated grasping surfaces to prevent
electric shock if you drill or drive into a live wire.
Motor
Your DEWALT tool is powered by a DEWALT-built motor. Be sure your power supply
battery agrees with the nameplate markings.
All D
EWALT tools are factory tested; if this tool does not operate, check your battery
pack.
Installing and Removing the Battery Pack (Fig. D1)
NOTE: Make sure your battery pack is fully charged.
To install the battery pack into the tool, centre the lock button (Pic D1 (C)) to
disable the trigger switch (See section Forward and Reverse button), align the front
of the battery with the notches inside the tool’s body and slide the battery pack firmly
into place until you hear the lock slide into place.
To remove the battery pack from the tool, depress the release buttons (E) on
both sides, remove the battery pack (F). Insert it into the charger as described in the
charger section of the manual.
Side Handle (Fig. D1 (A))
CAUTION: Always use side handle and hold rotary hammer with both hands. It
clamps to the front of the gear case as shown in Figure D1 and can be rotated 360˚
to permit right or left hand use.
Variable Speed Switch (Fig. D1 (B))
To turn the tool on, squeeze the trigger switch. 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.
The variable speed switch enables you to select the best speed for a particular
application. The farther you squeeze the trigger, the faster the tool will operate. Use
lower speeds for starting holes without a centrepunch, drilling in metals or plastics,
driving screws and drilling ceramics. For maximum tool life, use variable speed only
for starting holes or fasteners.
NOTE: Continuous use in variable speed range is not recommended.
It may damage the switch and should be avoided.
Forward/Reverse Control Button (Fig D1 (C))
A forward/reverse control button determines the direction of rotation and also
serves as a lock off button. To select forward rotation, release the trigger switch and
depress the forward/reverse 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
centre 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 and the tool has
