4. Use tools with the lowest vibration when there is a choice.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping safe control of it). Let the tool do the work.
7. To reduce vibration, maintain the tool as explained in this manual. If any abnormal vibration occurs, stop use
immediately.
Save these instructions.
GROUNDING
WARNING To prevent electric shock and death from incorrect grounding wire connection:
Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not
modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not
use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use.
If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.
Grounded Tools: Tools with Three Prong Plugs
1. Tools marked with "Grounding Required" have a three wire cord and three prong grounding plug. The plug
must be connected to a properly grounded outlet. If the tool should electrically malfunction or break down,
grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric
shock. (See 3-Prong Plug and Outlet.)
2. The grounding prong in the plug is connected through the green wire inside the cord to the grounding
system in the tool. The green wire in the cord must be the only wire connected to the tool's grounding system
and must never be attached to an electrically "live" terminal. (See 3-Prong Plug and Outlet.)
3. The tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all
codes and ordinances. The plug and outlet should look like those in the preceding illustration. (See 3-Prong
Plug and Outlet.)
