DO NOT CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO START A STALLED DRILL — THIS CAN DAMAGE THE DRILL. 6. To minimize stalling or breaking through the material, reduce pressure on drill and ease the bit through the last fractional part of the hole. 7. Keep the motor running when pulling the bit back out of a drilled hole. This will help prevent jamming. 8. With variable speed drills there is no need to center 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. REMOVABLE SDS CHUCK & 3 JAW KEYLESS CHUCK (D25304 ONLY) The D25304 is equipped with a removable quick change SDS chuck as well as a removable 3 jaw keyless chuck.

DRILLING IN METAL (D25103, D25203, D25303, D25304) When drilling with the depth rod, stop when end of rod reaches surface of material. An SDS to round shank adaptor chuck is required. Ensure that tool is in drill-only mode. (D25101, D25201 has no drill-only mode).

In the unlikely event that service is ever needed, take your tool to an authorized service location. NOTE: Large (5/16" to 1/2") holes in steel can be made easier if a pilot hole (5/32" to 3/16") is drilled first. Accessories CAUTION: When handling accessories after use, wear work (D25103, D25203, D25303, D25304) gloves. Accessories may be hot and m...
