1. Press the shaft lock button, hold down and rotate the
shaft by hand until it engages the shaft. Do not engage the
shaft lock button while multitool is running.
2. With the shaft lock button engaged, loosen and remove
the collet nut. Use the collet wrench if necessary.
3. Remove the collet by pulling it free from the shaft.
4. Install the appropriate size collet fully into the shaft and
reinstall the collet nut finger tight. Do not fully tighten the
nut when there is no bit or accessory installed.
The first step in using the multitool 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. The unique softgrip on the nose
allows for added comfort and control during use.
Always hold the tool away from your face. Accessories can be
damaged during handling and can fly apart as they come up to
speed.
When holding tool, do not cover the ventilation openings with
your hand. Blocking the ventilation openings could cause the
motor to overheat.
IMPORTANT! Practice on scrap material first to see how the
tool's high-speed action performs. Keep in mind that your
multitool will perform best by allowing the speed, along with the
correct Dremel accessory and attachment, to do the work for
you. Do not put pressure on the tool during use, if possible.
Instead, lower the spinning accessory lightly to the work surface
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 better to make a series of passes with the tool
rather than to do the entire job with one pass. A gentle touch
gives the best control and reduces the chance of error.
For best control in close work, grip the multitool like a pencil
between your thumb and forefinger. PICTURE 7
The "golf" grip method is used for heavier operations such as
grinding or cutting. PICTURE 8
OPERATING SPEEDS
This tool is a high speed multitool. Its speeds vary from
10.000 to 33.000 RPM. Adjusting the no. of RPM to your
project will give a better end result. To achieve the best results

U. Shaft Lock Button
1. Press the shaft lock button and rotate the shaft by hand
until it engages the shaft lock. Do not engage the shaft
lock button while multitool is running.
2. With the shaft lock button engaged, loosen (do not
remove) the collet nut. Use the collet wrench if necessary.
3. Insert the bit or accessory shank fully into the collet.
4. With the shaft lock button engaged, finger tighten the collet
nut until the bit or accessory shank is gripped by the collet.
NOTE: Be sure to read the instructions supplied with your
Dremel accessory for further information on its use.
Use only Dremel tested, high performance accessories.
when working with different materials, set the variable speed
control to suit the job. To select the right speed for the
accessory in use, practice with scrap material first.
NOTE: Speed is affected by voltage changes. A reduced
incoming voltage will slow the RPM of the tool, especially at
the lowest setting. If your tool appears to be running slowly,
increase the speed setting accordingly. The tool may not start
at the lowest switch setting in areas where outlet voltage is
less than 220 volts. Simply move the speed setting to a higher
position to begin operation.
The 300 Series multitool switch settings are marked on the
speed control switch. Refer to the Speed Settings chart on
pages 4-6 to help determine the proper speed for the material
being worked on and the accessory to use.
A) For use on drywall. For best results use at 33.000 RPM.
B) For use on wall and floor grout. Use setting 6-8.
*) Speed for light cuts. Caution, burning on deep grooves
possible.
)Depending on cutting direction relative to grain.
Most jobs can be accomplished using the tool at the highest
setting. However, certain materials (some plastics and metals)
can be damaged by high-speed generated heat and should be
worked on at relatively low speeds. Low speed operation
(15.000 RPM or less) is usually best for polishing operations
employing the felt polishing accessories. All brushing
applications require lower speeds to avoid wire discharge
from the holder. Let the performance of the tool do the work
for you when using lower speed settings. Higher speeds are
better for hardwoods, metals and glass and for drilling,
carving, cutting, routing, shaping and cutting dadoes or
rabbets in wood. The settings for approximate RPM's are:
