SECTION D: 22MM CORDLESS ROTARY HAMMER DW004/DW005
stopped.
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.
DW004 Hammer Drilling/Rotary Drilling Selector (Fig. D1 (D) D2)
To switch the tool from the drilling mode to the hammering mode (or vice-versa)
rotate the lever to the applicable symbol shown. For straight drilling, align the lever
with the drill bit symbol (B) as shown.
For hammer, align the lever with the
hammerdrill symbol (A). NOTE: The
selector must be in either drill, or
hammerdrill mode at all times. There
are no operable positions between the
two.
DW005 Hammer Drilling/Rotary
Drilling/Hammer Only with
Stop Rotation Selector (Fig. D1
(D) D3)
For hammer drilling and rotary drilling
follow the instructions above for the DW004. For hammer only with stop rotation for
light chipping, chiselling and light demolition work, rotate the lever to hammer
symbol (C). When using the DW005 in
hammer position with stop rotation for
light demolition work, the
forward/reverse selector should be in
the Forward position.
To Rotate or Align the Chisel
Bit (DW005 only)
If it is necessary to rotate the chisel bit
to obtain a more comfortable working
position, position the forward/reverse
control button to the centre lock-off
position. Move the drill mode selector
lever to the hammerdrill position. Rotate the chisel bit to the required position with
your hand. Move the drill mode selector back to the hammer position and begin
chiselling.
OPERATION
DRILLING
1. Always lock the trigger switch and remove the battery pack before attaching or
changing bits or accessories.
2. Use sharp drill bits only. For WOOD, use the low speed setting and twist drill
bits, spade bits, power auger bits, or hole saws. For METAL, use the low speed
setting and steel twist drill bits or hole saws. For MASONRY, such as brick,
cement, cinder block, etc., use carbide-tipped bits rated for percussion drilling.
3. Be sure the material to be drilled is anchored or clamped firmly.
If drilling thin material, use a wood ‘back-up’ block to prevent damage to the
material.
4. Always apply pressure in a straight line with the bit. Use enough pressure to
keep drill biting, but do not push hard enough to stall the motor or deflect the bit.
5. Hold tool firmly to control the twisting action of the drill.
6. IF DRILL STALLS, it is usually because it is being overloaded or improperly
used. 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.
7. To minimise the stalling or breaking through the material, reduce pressure on
drill and ease the bit through the last fractional part of the material.
8. Keep the motor running when pulling the bit back out of a drilled hole. This will
help prevent jamming.
9. With variable speed drills there is no need to centre punch the point to be
drilled. Use a slow speed to start the hole and accelerate by squeezing the
trigger harder when the hole is deep enough to drill without the bit skipping out.
DRILLING IN METAL
Start drilling with slow speed and increase to full power while applying firm pressure
on the tool. A smooth even flow of metal chips indicates the proper drilling rate. Use
a cutting lubricant when drilling metals. The exceptions are cast iron and brass
which should be drilled dry.
NOTE: Large (8mm (5/16”) to 12mm (1/2”)) holes in steel can be made easier if a
pilot hole (4mm (5/32”) to 5mm (3/16”)) is drilled first.
DRILLING IN WOOD
Start drilling with slow speed and increase to full power while applying firm pressure
on the tool. Holes in wood can be made with the same twist drills used for metal.
These bits may overheat unless pulled out frequently to clear chips from the flutes.
Work that is apt to splinter should be backed up with a block of wood.
