When drilling in masonry, use carbide tipped bits rated for percussion drilling. Be
certain that the bit is sharp. Ensure that the hammer mode is selected. Use a
constant and firm force on the tool to drill most effectively. A smooth, even flow of
dust indicates the proper drilling rate.
Chipping and Chiselling
Select the hammering only mode. Insert and SDS-plus
®
chisel and check that it is
properly locked. Adjust the side handle as required. Proceed as described for
hammer drilling.It may be necessary to briefly run the motor after having changed
from chiselling to rotary modes in order to align the gears..
NOTE: Select Forward direction when chipping and chiselling.
SDS Chuck (Fig. D4)
To insert bit, insert shank of bit about 19mm (3/4”) into chuck and twist the bit until it
clicks into place. The bit will be securely held.
To release bit, pull the collar back and remove the bit.
3 Jaw Chuck Adaptor (FIG. D5)
A chuck adaptor is available for the DW004 rotary hammer drill. The adaptor enables
a standard keyless or keyed chuck to be fitted so straight shank drill bits can be
used. The chuck adaptor should not be
used in the hammer or hammerdrill
position. This adaptor is designed to
function with non-hammer applications.
To fit the adaptor to the drill, follow the section ‘SDS Chuck, (Fig. D4)’.
To fit the chuck to adaptor, screw the chuck onto the adaptor in a clockwise
direction and ensure the chuck is tight on the adaptor. Open the jaws of the chuck
fully and fit the small lock screw down the centre of the chuck (note left hand
thread). Ensure the lock screw is tight by rotating the screw in an anti-clockwise
direction. (FIG. D5)
To remove the chuck, reverse the above procedure.
NOTE: On models DW004K2C and DW005K2C, both the chuck adaptor and 3 jaw
chuck are supplied with the drill. For other models, the chuck adaptor and 3 jaw
chuck are available as accessories.
