Functional Description - Makita 9910 Instruction Manual

Power tool use and care
1. 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.
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 adjust-
ments, 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, break-
age 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, tak-
ing 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 entangle-
ment of cloth work gloves in the moving parts may
result in personal injury.
Service
1. 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.
2. Follow instruction for lubricating and chang-
ing accessories.
BELT SANDER SAFETY WARNINGS
1. Hold the power tool by insulated gripping
surfaces, because the sanding surface may
contact its own cord. Cutting a "live" wire may
make exposed metal parts of the power tool "live"
and could give the operator an electric shock.
2. Ventilate your work area adequately when you
perform sanding operations.
Some material contains chemicals which may be
3.
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
Always use the correct dust mask/respirator for
4.
the material and application you are working with.
5. Always use safety glasses or goggles. Ordinary
eye or sun glasses are NOT safety glasses.
6. Hold the tool firmly with both hands.
7. Make sure the belt is not contacting the work-
piece before the switch is turned on.
Keep hands away from rotating parts.
8.
9. Do not leave the tool running. Operate the tool
only when hand-held.
10. This tool has not been waterproofed, so do not
use water on the workpiece surface.
SAVE THESE INSTRUCTIONS.
WARNING:
DO NOT let comfort or familiarity
