MAINTENANCE
Keep the tools clean using a soft, damp (not wet) cloth. Do not use solvents on
the plastic parts.
Lubrication is not necessary. After long use, have an authorized service center
maintain and lubricate the tool.
Should the drill chuck require replacement:
1. Remove the battery pack
2. Open the chuck jaws as widely as possible so you can access the chuck retain-
ing screw.
3. Unscrew the chuck retaining screw with a philips screwdriver. Note that this is a
left-hand-threaded screw and you must remove it by turning it clockwise.
4. Clamp the shorter arm of a large allen wrench in the chuck, aligning it with the
jaws so they grip three of its six flat sides.
5. Place the drill on a flat surface, and support the chuck with a piece of wood
about 8mm or 3/8” above the surface.
6. Strike the long arm of the wrench with a hammer so that the chuck turns
counter-clockwise and unscrews from the spindle.
This may require a fairly sharp blow.
7. Repeat the process in reverse to install a new chuck.
• To maintain the best performance of your rechargeable NiCd battery, prevent
it from overheating, both from overcharging and during storage. Occasionally
charge the battery for 6 hours. The battery may also benefit from a full discharge
from time to time.
