Set the speed indicator to t the job to achieve the best job results when work-
ing with different materials To select the right speed for each job, use a practice
piece of material Vary speed to nd the best speed for the accessory you are
using and the job to be done
Your Cordless Rotary Tool 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
Needs for Slower Speeds
Certain materials, however, (some plastics, for example) require a relatively slow
speed because at high speed the friction of the tool generates heat and causes
the plastic to melt Most work is done at high speed on your Cordless Rotary
Tool Lower speeds are needed only for
certain tasks
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 You can quickly learn that a slower
or faster speed is more effective just by ob-
serving what happens as you make a pass
or two at different speed
When working with plastic, for example, start at a slow rate of speed and
increase the speed until you observe that the plastic is melting at the point of
contact Then reduce the speed slightly to get the optimum working speed
1 Plastic and materials that melt at low temperatures should be cut at low
speeds
2 Polishing, bufng and cleaning with a wire brush must be done at speeds
below 15,000 RPM to prevent damage to the brush
3 Wood should be cut at high speed
4 Iron or steel should be cut at top speed if using tungsten carbide accessory,
but at slower speeds if using high-speed steel cutters If a high-speed steel
cutter starts to chatter—this normally means it is running too slow
Aluminum, copper alloys, lead alloys, zinc alloys and tin may be cut at various
speeds, depending on the type of cutting being done Use parafn or other suit-
able lubricant on the cutter to prevent the cut material from adhering to the cutter
teeth
Increasing the pressure on the tool is not the answer when it is not cutting as
you think it should Perhaps you should be using a different cutter, and perhaps
an adjustment in speed would solve the problem But leaning on the tool seldom
helps
