Sander Safety Warnings; Functional Description - Makita BO4900V Instruction Manual

2. 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.
3. Disconnect the plug from the power source and/or
remove the battery pack, if detachable, 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.
4. 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.
5. Maintain power tools and accessories. 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.
6. Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges are
less likely to bind and are easier to control.
7. 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.
8. Keep handles and grasping surfaces dry, clean
and free from oil and grease. Slippery handles and
grasping surfaces do not allow for safe handling and
control of the tool in unexpected situations.
9. When using the tool, do not wear cloth work
gloves which may be entangled. The entanglement
of cloth work gloves in the moving parts may result in
personal injury.
