SAFETY WARNINGS
WORK ENVIRONMENT
1. Keep the work area clean, tidy and well lit. Cluttered and dark areas invite
accidents.
2. DO NOT operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Anyone
entering the work area must wear personal protective equipment.
Distractions can cause you to lose control and fragments of work may fly
away and cause injury.
4. Store power tools properly when not in use. Abrasive products should be
stored in a dry, secure place out of the reach of children.
5. Please read these instructions carefully and retain for future reference.
ELECTRICAL SAFETY
1. Power tool plugs must match the outlet. NEVER modify the plug in any way.
DO NOT use adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce the risk of electric
shock.
2. This machine is designed for indoor environments and must not be used for
other purposes. DO NOT expose power tools to rain or wet conditions.
Water entering a power tool will increase the risk of electric shock.
3. DO NOT abuse the power cable. NEVER use the cable for carrying, pulling
or unplugging the power tool. Keep the cable away from heat, oil, sharp
edges or moving parts. Damaged or entangled cables increase the risk of
electric shock.
4. Position the power cable so that it cannot be inadvertently pulled or
pinched, and where it does not cause a trip hazard.
5. Before cleaning or maintenance operations, always unplug the machine
from the power supply.
CAUTION: FAILURE TO FOLLOW THESE PRECAUTIONS COULD RESULT IN
PERSONAL INJURY, AND/OR DAMAGE TO PROPERTY.
