Dremel 8220 Manual De Instrucciones página 22

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.
CHANGING ACCESSORIES
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.
EZ TWIST™ INTEGRATED WRENCH/NOSE CAP
PICTURE 4
F. EZ Twist™ integrated wrench/nose cap
This nose cap has an integrated wrench allowing you to loosen
and tighten the collet nut without the use of the standard collet
wrench.
1. Unscrew the nose cap from the tool, line-up the steel insert
on inside of the cap with the collet nut.
2. With the shaft lock engaged twist nose cap counter
clockwise to loosen the collet nut. Do not engage the shaft
lock button while multitool is running.
3. Insert the bit or accessory shank fully into the collet.
4. With the shaft lock engaged twist nose cap clockwise to
tighten the collet nut.
5. Screw the nose cap back into its original position.
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.
BALANCING ACCESSORIES
For precision work, it is important that all accessories be in good
balance (much the same as the tires on your automobile). To
true up or balance an accessory, slightly loosen collet nut and
give the accessory or collet a 1/4 turn. Re tighten collet nut and
run the Rotary Tool. You should be able to tell by the sound and
feel if your accessory is running in balance. Continue adjusting
in this fashion until best balance is achieved.
USE
GETTING STARTED
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
2610034063-8220AUS-LAM.indb 22
the housing. This taper permits the tool to be grasped much like
a pen or pencil.
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.
HOLDING THE TOOL
For best control in close work, grip the multitool like a pencil
between your thumb and forefinger. PICTURE 5
The "golf" grip method is used for heavier operations such as
grinding or cutting. PICTURE 6
OPERATING SPEEDS
To select the right speed for each job, use a practice piece of
material.
SLIDE "ON/OFF" SWITCH
The tool is switched "ON" by the slide switch located on the
top side of the motor housing.
TO TURN THE TOOL "ON", slide the switch button forward.
TO TURN THE TOOL "OFF", slide the switch button backward.
HIGH PERFORMANCE MOTOR
Your tool is equipped with a high performance rotary tool motor.
This motor expands the versatility of the rotary tool by driving
additional Dremel attachments.
ELECTRONIC MONITORING
Your tool is equipped with an internal electronic monitoring
system that provides a "soft start", which will reduce the
stresses that occur from a high torque start. The system also
helps to maximize motor and battery performance by cutting
the voltage to the tool when stall conditions (see section "Stall
Protection") occur. The motor and battery pack are protected by
cutting back the voltage to the motor in these situations.
VARIABLE SPEED SLIDE SWITCH
Your tool is equipped with a variable speed slide switch. The
speed may be adjusted during operation by sliding the switch
back or forth between any one of the settings.
The speed of Rotary Tool is controlled by setting this dial on the
housing. PICTURE 7
