Maintenance - DeWalt D25012-XE Instruction Manual

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 [7.9 mm to 12.7 mm (5/16" to 1/2")] holes in steel can be made easier
if a pilot hole [4 mm to 4.8 mm (5/32" to 3/16")] is drilled first.
DRILLING IN WOOD
An SDS Plus to round shank adaptor chuck is required. Ensure that tool is in drill-
®
only mode. 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. For larger holes, use spade bits, power auger bits, or hole saws. Work that is
apt to splinter should be backed up with a block of wood.
HAMMERDRILL OPERATION
1. When drilling, use just enough force on the hammer to keep it from bouncing
excessively or "rising" off the bit. Too much force will cause slower drilling
speeds, overheating, and a lower drilling rate.
2. Drill straight, keeping the bit at a right angle to the work. Do not exert side
pressure on the bit when drilling as this will cause clogging of the bit flutes and a
slower drilling speed.
3. When drilling deep holes, if the hammer speed starts to drop off, pull the bit
partially out of the hole with the tool still running to help clear debris from the
hole.
4. For masonry, use carbide-tipped bits or masonry bits. A smooth even flow of
dust indicates the proper drilling rate.
Chipping and Chiselling (D25013)
1. To switch from hammer drilling to chiselling, first insert the SDS Plus® chisel
and check if it is properly locked.
2. When switching from hammer drilling mode to chiselling mode, turn the chisel to
the desired position. If you find resistance during mode change, turn the chisel
slightly to engage the spindle lock.
Depth Rod (Fig. 4)
TO ADJUST THE DEPTH ROD
1. Push in and hold the depth rod release button (J) on the side handle.
2. Move the depth rod (D) so the distance between the end of the rod and the end
of the bit equals the desired drilling depth.

3. Release the button to lock rod into position. When drilling with the depth rod, stop
when end of rod reaches surface of material.

MAINTENANCE

WARNING: Shock Hazard. To reduce the risk of serious personal injury, turn
tool off and disconnect from power source before making any adjustments or
removing/installing attachments or accessories.
Lubrication
Your power tool requires no additional lubrication.
Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once
a week. To minimize the risk of eye injury, always wear ANSI Z87.1 approved eye
protection when performing this.
WARNING: Never use solvents or other harsh chemicals for cleaning the
non-metallic parts of the tool. These chemicals may weaken the plastic 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 certified
