CAUTION: Pressing excessively on the tool
will not speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of your drill
bit, decrease the tool performance and shorten the
service life of the tool.
CAUTION: Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION: A stuck drill bit can be removed
simply by setting the reversing switch to reverse
rotation in order to back out. However, the tool
may back out abruptly if you do not hold it firmly.
CAUTION: Always secure small workpieces in
a vise or similar hold-down device.
CAUTION: If the tool is operated continuously
until the battery cartridge has discharged, allow
the tool to rest for 15 minutes before proceeding
with a fresh battery.
MAINTENANCE
CAUTION: Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
