Use And Care Manual

USING THE CORDLESS ROTARY TOOL
The first step in learning to use the Cordless Rotary Tool is to get the “feel” of it. Hold it in your hand
and feel its weight and balance. Feel the taper of the housing. This taper permits the tool to be grasped
much like a pen or pencil.
When you turn on the tool for the first time, hold it away from your face. Accessories can be damaged
during handling, and can fly apart as they come up to speed. This is not common, but it does happen.
Practice on scrap materials first to see how the Cordless Rotary Tool works. Keep in mind that the work
is done by the speed of the tool and by the accessory in the collet. You should not lean on or push the
tool into the work. Instead, lower the spinning accessory lightly to the work and allow it to touch the
point at which you want to begin. Concentrate on guiding the tool over the work using very little
pressure from your hand. Allow the accessory to do the work.
Usually, it is best to make a series of passes with the tool rather than attempt to do all the work in one
pass. Pass the tool back and forth over the work, much as you would a small paint brush. 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.
OPERATING SPEEDS FOR ACCESSORIES
Set the speed indicator to fit the job in order to achieve the best results when working with
different materials. To select the right speed for each job, use a practice piece of material. Test by
varying the speed to find the ideal speed for the accessory you are using and the job to be done.
On the the tool, there is a HI and LO switch (see Figure 8). When the switch
indicator is in the HI position, the tool runs at approximately 10,000 RPM.
When the switch indicator is in the LO position, the tool runs at approximately
5,000 RPM.
NOTE: Speed is affected by voltage changes. Weaker batteries with reduced
voltage will slow the RPM of the tool, especially at the lowest setting. If your tool
appears to be running more slowly than normal, replace the batteries with fresh
ones to increase tool speed.

**WARNING!** Always be sure the tool is in the “OFF” position before changing
accessories, changing collets or servicing your cordless rotary tool
COLLET - To loosen, first press shaft lock button and rotate the shaft by hand until the lock engages
the shaft preventing further rotation (see Figure 1).
CAUTION: Do not engage lock while the Rotary Tool is running.
With the shaft lock engaged, use the collet wrench to loosen the collet nut if necessary. Change
accessories by inserting the new one into the collet as far as possible to minimize run out and unbalance.
With the shaft lock engaged, finger tighten the collet nut until the accessory shank is gripped by the
collet. Avoid excessive tightening of the collet nut.
COLLET IDENTIFICATION - Two different size collets (see Figure 2) to accommodate different
shank sizes are available with your Cordless Rotary Tool. Collet sizes can be identified by the rings on
the back end of collet.
To install a different collet, remove the collet nut and remove the old collet. Insert the unslotted end of
the collet into the hole in the end of the tool shaft. Replace collet nut on the shaft. Always use the collet
which matches the shank size of the accessory you plan to use. Never force a larger diameter shank
into a collet.
BALANCING ACCESSORIES - For precision work, it is important that all accessories be in
good balance (much the same as the tires on your automobile).
