Operating Instructions
ON/OFF switch
1. The on/off switch is located on the underside of the handle. It has two setting “0” (Off) and “I” 
(On). 
2. To switch on the tool, press the switch into the “I” (On) position. There is no need to hold it 
down as it will automatically lock in position. 
3. To switch the tool off, simply press the switch back into the “0” (Off) position. 
4. Always ensure that the switch is in the Off position before connecting the tool to the electric 
outlet. Always disconnect the tool from the electric outlet when not in use. 
Operating speeds
To select the right speed for each job, use a practice piece of material. 
NOTE: Speed is affected by voltage changes. A reduced incoming voltage will slow the 
RPM of the tool. 
 
Your tool is equipped with an internal electronic feedback system that provides a “soft start”, 
which will reduce the stresses that occur from a high torque start. The system also helps to keep 
the preselected speed virtually constant between no-load and load conditions. 
 
Your tool is equipped with a variable speed dial. The speed may be adjusted during operation by 
presetting the dial on or between any one of the settings. 
 
Certain materials, however, (some plastics and precious metals, for example) require a relatively 
slow speed because at high speed the friction of the accessory generates heat and may cause 
damage to the material. 
 
Slow speeds (15,000 RPM or less) usually are best for polishing operations employing the felt 
polishing accessories. They may also be best for working on delicate wood carving and fragile 
model parts. (All brushing applications require lower speeds to avoid wire discharge from the 
holder.) 
 
Higher speeds are better for carving, cutting, routing, shaping, cutting dadoes or rabbets in wood. 
 
Hardwoods, metals and glass require high speed operation, and drilling should also be done at 
high speeds. 
 
The point to remember is this: Many applications and accessories in our line will provide the best 
performance at full speed, but for certain materials, applications, and accessories, you need 
slower speeds, which is the reason our variable speed models are available. 
 
Ultimately, the best way to determine the correct speed for work on any material is to practice 
for a few minutes on a piece of scrap, even after referring to the chart. You can quickly learn that 
a slower or faster speed is more effective just by observing what happens as you make a pass or 
two at different speeds. When working with plastic, for example, start at a slow rate of speed and
