To select the right speed for each job, use a practice piece of
material.
VARIABLE SPEED DIAL
Your tool is equipped with a variable speed dial. The speed
may be adjusted during operation by presetting the dial on or
between any one of the settings.
You can refer to the charts on page 4
to determine the proper
speed, based on the material being worked and the type of
accessory being used. These charts enable you to select both
the correct accessory and the optimum speed at a glance.
The speed of Rotary Tool is controlled by setting this dial on the
housing (

Needs for Slower Speeds
Certain materials, however, (some plastics and precious metals,
for example) require a relatively slow speed because at high
speed the friction of the accessory generates heat and may
cause damage to the material.
Slow speeds (15,000 RPM or less) usually are best for polishing
operations employing the felt polishing accessories. They may
also be best for working on delicate projects as “eggery” work,
delicate wood carving and fragile model parts. (All brushing
applications require lower speeds to avoid wire discharge from
the holder.)
Higher speeds are better for carving and shaping wood.
Hardwoods, metals and glass require high speed operation, and
drilling should also be done at high speeds.
The point to remember is this: Many applications and
accessories in our line will provide the best performance at full
speed, but for certain materials, applications, and accessories,
you need slower speeds, which is the reason our variable
speed models are available.
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, even after referring to the chart. You can quickly learn
that a slower or faster speed is more effective just by observing
what happens as you make a pass or two at different speeds.
Some rules of thumb in regard to speed:
•
Polishing, buffing and cleaning with any type of bristle brush
must be done at speeds not greater than 15,000 RPM to
prevent damage to the brush.
• Increasing the pressure on the tool is not the answer when
it is not performing as you think it should. Perhaps you
should be using a different accessory, and perhaps an
adjustment in speed would solve the problem. Leaning on
the tool does not help.
Let speed do the work!
STALL PROTECTION
This tool has a stall protection feature built into it to protect the
motor in the event of a stall. If you stall the tool for too long,
or bind the bit in a work piece, especially at high speeds, it
will automatically turn itself off. Simply take the tool out of the
material you were stalled in, turn it back on again to continue
using it.
MAINTENANCE
Preventive maintenance performed by unauthorized personnel
may result in misplacing of internal wiring and components
which could cause serious hazard. We recommend that all tool
service be performed by a Dremel Service Facility. To avoid
injury from unexpected starting or electrical shock, always
remove plug from wall outlet before performing service or
cleaning.
CLEANING
!
WARNING
TO AVOID ACCIDENTS, ALWAYS
DISCONNECT THE TOOL AND/OR
CHARGER FROM THE POWER SUPPLY BEFORE CLEANING.
The tool can be cleaned most effectively with compressed dry air.
Always wear safety goggles when cleaning tools with compressed
air.
Ventilation openings and switch levers must be kept clean
and free of foreign matter. Do not attempt to clean the tool by
inserting pointed objects through an opening.
!
WARNING
CERTAIN CLEANING AGENTS AND
SOLVENTS DAMAGE PLASTIC PARTS.
Some of these are: gasoline, carbon tetrachloride, chlorinated
cleaning solvents, ammonia and household detergents that contain
ammonia.
SERVICE AND WARRANTY
!
WARNING
NO USER SERVICEABLE PARTS INSIDE.
PREVENTIVE MAINTENANCE
PERFORMED BY UNAUTHORIZED PERSONNEL MAY RESULT
IN INCORRECT CONNECTION OF INTERNAL WIRING AND
COMPONENTS WHICH COULD CAUSE SERIOUS HAZARD.
We
recommend that all tool service be performed by a Dremel Service
Centre. Servicemen: Disconnect the tool and/or charger from the
power source before servicing.
This DREMEL product is guaranteed in accordance with
statutory/country-specific regulations; damage due to normal
wear and tear, overload or improper handling are excluded from
the warranty.
F. 482 1/16” Collet
G. 481 3/32” Collet
Note: Most rotary tool kits do not include all four collet sizes.
COLLET IDENTIFICATION CHART
Collet sizes can be identified by the rings on the back end of
collet.
1/32” Collet has one (1) ring.
1/16” Collet has two (2) rings.
3/32” Collet has three (3) rings.
1/8” Collet has no rings. (Included in most tool kits on the tool).
FIXING STUCK COLLETS
It is possible for a collet to get stuck within the collet nut
especially if a collet nut is tightened onto the tool without a bit
in place. If this happens, the collet can be removed from the
collet nut by pushing the shank of an accessory into the hole
in the collet nut. This should cause the collet to pop out of the
collet nut.
COLLET NUT
To loosen, first press shaft lock button and rotate the shaft
by hand until the lock engages the shaft preventing further
rotation. Your Dremel 2050 is equipped with a quick shaft lock
mechanism.
!
WARNING
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. The collet nut must be loosely
threaded on when inserting an accessory. Change accessories
by inserting the new one into the collet as far as possible to
minimize runout and unbalance.
With the shaft lock engaged, use collet wrench to securely
tighten the collet nut
(PICTURE 4). Avoid excessive tightening
of the collet nut when there is no bit inserted.

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 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.
