Maintenance - DeWalt DC212-XE Instruction Manual

WARNING: To reduce the risk of personal injury, ALWAYS ensure workpiece is
anchored or clamped firmly. If drilling thin material, use a wood "back-up" block to
prevent damage to the material.
WARNING: To reduce the risk of personal injury, ALWAYS operate the tool with
the side handle properly installed. Failure to do so may result in the side handle
slipping during tool operation and subsequent loss of control. Hold tool with both
hands to maximize control.
1. Use sharp drill bits only. For MASONRY, such as brick, cement, cinder block, etc.,
use carbide-tipped bits rated for percussion drilling.
2. Always apply pressure in a straight line with the bit. Use enough pressure to keep
drill biting, but do not push hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting action of the drill. If model
is not equipped with side handle, grip drill with one hand on the handle and one
hand on the battery pack.
CAUTION: Drill may stall if overloaded causing a sudden twist. Always expect the
stall. Grip the drill firmly to control the twisting action and avoid injury.
4. IF DRILL STALLS, it is usually because it is being overloaded or improperly used.
RELEASE TRIGGER IMMEDIATELY, remove drill bit from work, and determine
cause of stalling. DO NOT CLICK TRIGGER ON AND OFF IN AN ATTEMPT TO
START A STALLED DRILL — THIS CAN DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material, reduce pressure on drill and
ease the bit through the last fractional part of the hole.
6. Keep the motor running when pulling the bit back out of a drilled hole. This will
help prevent jamming.
7. 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.
DRILLING IN MASONRY
When drilling in masonry, use carbide-tipped bits rated for percussion drilling and be
certain that the bits are 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.

MAINTENANCE

WARNING: To reduce the risk of serious personal injury, turn tool off and
disconnect tool from power source before making any adjustments or removing/
installing attachments or accessories.
Cleaning
WARNING: Blow dirt and dust out of all air vents with dry air at least once a week.
Wear proper ANSI Z87.1 (CAN/CSA Z94.3) eye protection and proper NIOSH/OSHA/
MSHA respiratory 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.
CHARGER CLEANING INSTRUCTIONS
WARNING: Shock hazard. Disconnect the charger from the AC outlet before
cleaning. Dirt and grease may be removed from the exterior of the charger using a
cloth or soft non-metallic brush. Do not use water or any cleaning solutions.
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.
Repairs
This charger is not user serviceable. There are no user serviceable parts inside the
charger.
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.
