Vibration Safety
This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent
physical injury, particularly to the hands, arms and shoulders. To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an extended period should first be examined by a doctor and then
have regular medical check-ups to ensure medical problems are not being caused or worsened from use. Pregnant
women or people who have impaired blood circulation to the hand, past hand injuries, nervous system disorders,
diabetes, or Raynaud’s Disease should not use this tool. If you feel any medical or physical symptoms related to
vibration (such as tingling, numbness, and white or blue fingers), seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces the blood supply to the hands and fingers, increasing the risk of
vibration-related injury.
3. Use tools with the lowest vibration when there is a choice between different processes.
4. Include vibration-free periods each day of work.
5. Grip workpiece as lightly as possible (while still keeping safe control of it). Let the tool do the work.
6. To reduce vibration, maintain the tool as explained in this manual. If any abnormal vibration occurs, stop use
immediately
Double insulation
Double insulation is a concept in safety in electric power tools, which eliminates the need for the usual three-wire
Grounded
power cord. All exposed metal parts are isolated from the internal metal motor components with
protecting insulation. Double
insulated tools do not need to be grounded. The double insulated system is intended
to protect the user from shock resulting
from a break in the tool’s internal wiring . Observe all normal safety
precautions to avoid electrical shock.

Observe all normal safety precautions to avoid electrical shock.
NOTE: Servicing of a tool with double insulation requires extreme care and knowledge of the system and shouId
Be
Performed only by a qualified service technician. For service, we suggest you return the tool to the nearest
authorized service
center for repair. Always use original factory replace- ment parts when servicing.
Electrical Connection
This tool has a precision-built electric motor. It should be connected to a power supply that is 120 volts, 60 Hz, AC
o
nly
(normal household current). Do not operate this tool on direct current (DC). A substantial voltage drop will
cause a loss of
power and the motor will overheat. If your tool does not operate when plugged into an outlet,
double-check the power supply.
Grounding Instruction
In the event of a malfunction or break- down, grounding provides a path of least resistance for electric current to
reduce the
risk of electric shock. This tool is equipped with an electric cord having an equipent-grounding
conductor and a grounding
plug. The plug must be plugged into a matching outlet that is properly installed and
grounded in accordance with all local
codes and ordinances.
Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a qualified
electrician.
Improper connection of the equipment-grounding conductor can result. It in electrical shock. The conductor with
Insulation having an outer surface that is green with or without yellow stripes is the equipment-grounding
conductor. If repair or replacement of the electric cord or plug is necessary, do
not connect the equipment grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the grounding
instructions are not completely understood, or if in doubt as to whether the
tool is properly grounded. Repair or replace a damaged or worn cord
immediately.
This tool is intended for use on a circuit that has an outlet like the
one shown in Fig.1. It also has a grounding pin like the one shown.
