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
tools operation. If damaged, have the power tool
repaired before use. Many accidents are caused by
poorly maintained power tools.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
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.

Decker, the warranty will not be valid.
