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 rmly 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 rmly.
CAUTION: Always secure 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
o󰀨 and the battery cartridge is removed before attempt-
ing to perform inspection or maintenance.
NOTICE: Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
