4) POWER TOOL USE AND CARE
a) Do not force the power tool. Use the
correct power tool for your application. The
correct power tool will do the job
better and safer at the rate for which it
was designed.
b) Do not use the power tool if the switch
does not turn it on and off. Any power
tool that cannot be controlled with the switch
is dangerous and must be repaired.
c) Disconnect the plug from the power source
and/or the battery pack from the power
tool before making any adjustments,
changing accessories, or storing power
tools. Such preventive safety measures
reduce the risk of starting the power tool
accidentally.
d) Store idle power tools out of the reach
of children and do not allow persons
unfamiliar with the power tool or these
instructions to operate the power tool.
Power tools are dangerous in the hands of
untrained users.
e) Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool's operation.
If damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean.
Properly maintained cutting tools with sharp
cutting edges are less likely to bind and are
easier to control.
g) Use the power tool, accessories and
tool bits etc., in accordance with these
instructions taking into account the working
conditions and the work to be performed.
Use of the power tool for operations different
from those intended could result in a
hazardous situation.
5) SERVICE
a) Have your power tool serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
Additional safety instructions for drills
• Wear ear protectors. Exposure to noise can
cause hearing loss.
• Use auxiliary handles supplied with the
tool. Loss of control can cause personal injury.
• Hold power tool by insulated gripping
