You can tell by the sound and feel if your accessory is running
in balance. To true up or balance an accessory, slightly pull
back the EZ Change™ levers and give the accessory a 1/4 turn.
Release the levers and run the tool. Continue adjusting like this
until best balance is achieved.
USING ATTACHMENTS
Your Dremel 4200 can be equipped with different attachments that
expand the functionality of your tool.
Not all attachments listed below are included in your kit. Use
only Dremel tested, high performance attachments! You can
order attachments through the Dremel Service Center or go to
www.dremel.com for attachment and accessory compatibility.
1. Use the Flexible Shaft (225) for precise, detailed work or hard to
reach places. Refer to figure 11.
For optimum performance allow your new Flexshaft to run at
high speed on your multitool in a vertical position for 2 minutes
before use.
2. Use the Dremel Shaping Platform (576) to sand and grind at perfect
90 and 45 degree angles. Refer to figure 12.
3. Use the Dremel Detailer's Grip (577) to have even better control of
your Multitool. Refer to figure 12.
4. Use the Multipurpose Cutting Kit (565/566) for controlled cutting in a
variety of materials. Refer to figure 13.
5. Use the Wall & Floor Grout Removal Kit (568) for removing grout
from between wall and floor tiles. Refer to figure 14.
6. Use the Line & Circle Cutter (678) to make perfect holes and straight
cuts. Refer to figure 15.
7. Use the Right Angle Attachment (575) to use accessories in right
angle for hard to reach places. Refer to figure 16.
8. Use the Comfort Guard Attachment to protect you from dust and
sparks. Refer to figure 17.
OPERATION
Practice on scrap material first to see how the tool performs.
Your multitool performs best by allowing the tool, along with
the correct Dremel accessory, attachment and speed, to do
the work for you. Lower the spinning accessory gently 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. Increasing pressure on the tool is not the answer
when it is not performing properly. Try a different accessory or
speed setting to achieve the desired result.
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.
HOLDING THE TOOL
The design of the tool is symmetrical and contains plenty of soft grip. The
tool can be held comfortably in many positions.
Always hold the tool away from your face. Accessories can
damage during operation and can fly apart as they come up to
speed.
When you hold the tool, do not cover the ventilation openings
with your hand. Blocking the ventilation openings can cause the
motor to overheat.
1. Get the "feel" of the tool before using it by holding it in your hand and
feeling its weight and balance.
2. Grip the tool like a pencil between your thumb and forefinger for the
best control in close work. Refer to figure 6.
3. Use the "golf" grip for heavier operations such as grinding or cutting.
Refer to figure 7.
POWERING THE TOOL
The tool is turned "ON" and "OF" by the On/Off switch on the top side of
the motor housing.
1. Insert the power plug into the socket.
2. Turn the tool "ON" by sliding the On/Off switch forward.
3. Turn the tool "OFF" by sliding the On/Off switch backward.
Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may grab
the surface and pull the power tool out of your control.
SETTING THE RIGHT SPEED
Your tool is equipped with a variable speed dial. You can adjust the
speed during operation by pre-setting the dial on or between any one of
the settings.
Switch Setting Speed Range (/min) Qualification
5 5,000
10 10,000
15 15,000
Low speed
20 20,000
25 25,000
30 30,000
33 33,000
High speed
Refer to the Technical Specifications of the accessory (on-line
or on package) for the Maximum Speed. Do not use high speed
when using wire brushes. At high speed, wires can discharge
from the holder.
1. Use a low speed (15,000 /min or less) when:
a. Polishing, buffing and cleaning with a wire brush.
b. Polishing with felt polishing accessories.
c. Working with materials that can be damaged by high-
speed generated heat. Some materials burn or melt at low
temperatures.
2. Use higher speeds for hardwoods, metals and glass and for drilling,
carving, cutting, routing and shaping.
If a high speed steel cutter starts to vibrate, it usually indicates
that it is running too slow.
3. Aluminium, copper alloys, lead alloys, zinc alloys and tin may be cut
at various speeds, depending on the type of cutting.
Use a paraffin or other suitable lubricant (not water) on the
cutter to prevent the material from adhering to the cutter teeth.
MAINTENANCE AND REPAIR
Always unplug the tool from the power source before you make
any adjustments, change accessories, service, clean, etc. This
reduces the risk of starting the tool accidentally.
Have your power tool serviced by a qualified repair person who
uses only identical replacement parts. We recommend that all
tool service be performed by a Dremel Service Centre. This
will ensure the safety of the tool. Maintenance performed by
unauthorized personnel can result in incorrect connection of
internal wiring and components which can cause serious hazard.
You can only inspect and replace the carbon brushes. There are
no other serviceable parts inside the tool.
CLEANING
1. Clean ventilation openings, switch and levers of the tool with
compressed dry air.
Do not clean the tool by inserting pointed objects through an
opening.
Wear safety goggles to protect your eyes.
2. Clean the surface of the tool with a damp cloth.
