9. A ratcheting sound heard while using the tool in low speed
indicates that the clutch is disengaging due to a high load.
Continuous use of the tool with the clutch ratcheting is not
recommended.
DRILLING IN METAL
Use a cutting lubricant when drilling metals. The exceptions are cast
iron and brass which should be drilled dry. The cutting lubricants that
work best are sulphurized cutting oil or lard oil; bacon grease will also
serve the purpose.
DRILLING IN WOOD
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. For larger holes, use Power Drill Wood Bits. Work that
is apt to splinter should be backed up with a block of wood. When
using Self Feed bits, no pressure is required as these bits will pull
themselves into the wood.
NOTE: If the clutch slips while using a self feed bit, rock the drill
slightly by pushing the switch handle toward the material being drilled
and then pulling it back toward you several times.
DRILLING IN MASONRY
Use carbide tipped masonry bits at low speeds. Keep even force on
the drill but not so much that you crack the brittle materials. A smooth,
even flow of dust indicates the proper drilling rate.

Cleaning
With the tool motor running, blow dirt and dust out of all air vents with
dry air at least once a week.
Lubrication
Your tool was properly lubricated before leaving the factory. In from
two to six months, depending upon use, take or send your tool to a
D WALT Service Center or other qualified service organization for a
E
complete cleaning, inspection and relubrication.
Tools used constantly on production or heavy duty jobs or exposed to
heat may require more frequent lubrication. Tools "out of service" for
long periods should be relubricated before being put back into
service.
Motor Brushes
This D WALT tool uses an advanced brush system which automatically
E
stops the drill when the brushes wear out. This prevents serious damage
to the motor.
Accessories
Recommended accessories for use with your tool are available at
extra cost from your distributor or local service center.
CAUTION: The use of any non-recommended accessory may be
hazardous.
