Cut a little material on each pass until you reach the desired depth. For most work, the deft, gentle touch is best. With it, you have the best control, are less likely to
make errors, and will get the most efficient work out of the accessory.
For best control in close work, grip the Rotary Tool like a pencil between your thumb and forefinger.
The “handgrip” method of holding the tool is used for operations such as grinding a flat surface or using cutoff wheels.
Operating Speeds For Accessories
Set the speed indicator to fit the job to achieve the best job results when working with different materials.
To select the right speed for each job, use a practice piece of material. Vary speed to find the best speed for the accessory you are using and the job to be done.
Your Cordless RotaryTool is equipped with a variable speed control dial. To turn the tool ON, rotate dial to desired number to select the operating speed needed from 5,000 – 25,000 RPM. To turn tool OFF, rotate dial to the “0” off position.
You can refer to the charts on page 13, 14, and 15 to determine the proper speed, based on the material being worked and the type of accessory being used. These charts enable you to select both the correct accessory and the optimum speed at a glance.
Needs for Slower Speeds
Certain materials, however, (some plastics, for ex- ample) require a relatively slow speed because at high speed the friction of the tool generates heat and caus- es the plastic to melt.
Most work is done at high speed on your Cordless Rotary Tool. Lower speeds are needed only for certain tasks.
The speed of Model 780 is controlled by rotating this dial to desired setting on dial.
