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 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 all air vents with clean, dry air at least once a
week. To minimize the risk of eye injury, always wear AS/NZS standard 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
service centers or other qualified service organizations, always using identical
replacement parts.

DRILLING IN METAL
D25123-XE, D25124-XE, D25213-XE, D25314-XE
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. 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. The cutting lubricants that work best are
sulphurized cutting oil or lard oil; bacon-grease will also serve the purpose.
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
D25123-XE, D25124-XE, D25213-XE, D25314-XE
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.
DRILLING IN MASONRY
D25123-XE, D25124-XE, D25213-XE, D25314-XE
When drilling in masonry, use SDS Plus
®
carbide tipped bits rated for percussion
drilling and be certain that the bit is sharp. Use a constant and firm force on the tool
to drill most effectively. A smooth, even flow of dust indicates the proper drilling rate.
Depth Rod
To adjust the depth rod.
1. Push in and hold the button on the side handle.
2. Move the depth rod (B) 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.
