4.Adjust the side handle (front or rear position) (C).

5.Assemble the centering bit and adapter shank into core bit.

6.Mark the spot where the hole is to be drilled.

7.Place the centering bit on that mark and depress the trigger switch (A).

NOTE: Some core drills require the removal of centering bit after about 1 cm of penetration. If so, remove and continue hammerdrilling.

8.When hammerdrilling through a structure thicker than the depth of the core bit, break away the round cylinder of concrete or core inside the bit at regular intervals. To avoid unwanted breaking away of concrete around the hole, first drill a hole the diameter of the centering bit completely through the structure. Then drill the cored hole halfway from each side of the structure.

9.To stop the tool, release the trigger switch. Always turn the tool off when work is finished and before unplugging.

4.Adjust the side handle (front or rear position) (C).

5.Depress the trigger switch (A).

6.Apply only enough pressure to engage active vibration control (refer to Active Vibration Control).

7.To stop the tool, release the trigger switch. Always turn the tool off when work is finished and before unplugging.

MAINTENANCE

WARNING: To reduce the risk of injury, turn unit off and disconnect tool from power source before installing and removing accessories, before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

Your DEWALT power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.

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 an authorized service center for a complete cleaning, inspection and lubrication. Tools used constantly on production jobs will need relubrication more often. Also, tools “out of service” for long periods should be relubricated before being put back to work.

Cleaning

WARNING: Blow dirt and dust out of the main housing with dry air as often as dirt is seen collecting in and around the air vents. Wear approved eye protection and approved dust mask when performing this procedure.

WARNING: Never use solvents or other harsh chemicals for cleaning the non-metallic parts of the tool. These chemicals may weaken the materials used in these parts. Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

Repairs

To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment (including brush inspection and replacement) should be performed by authorized service centers or other qualified service personnel, always using identical replacement parts.
