The "golf" grip method is used for heavier operations such as
grinding or cutting. PICTURE 10
Nose Piece
For performing precision tasks a separate nose piece is
available. It has a trilobular shape which allows the user to pinch
the nose piece comfortably between thumb and forefinger. Its
sleek shape has an excellent line of sight for performing detailed
etching, carving and engraving work. This nose piece is not
included in every kit. PICTURE 11
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 FEEDBACK
Your tool is equipped with an internal electronic feedback system
that provides a "soft start", which will reduce the stresses that
occur from a high torque start. The system also helps to keep
the preselected speed virtually constant between no-load and
load conditions.
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.
The speed of Rotary Tool is controlled by setting this dial on the
housing. PICTURE 12

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 and shaping.
Some guidelines regarding tool speed:
should be cut at low speeds.
done at speeds no greater than 15,000 RPM to prevent
damage to the brush and your material.
indicates that it is running too slowly.
may be cut at various speeds, depending on the type of
cutting being done. Use a paraffin (not water) or other
suitable lubricant on the cutter to prevent the cut material
from adhering to the cutter teeth.
NOTE: 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.
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.
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.
