FIG. B

For best control in close work, grip the Rotary Tool like a pencil between your thumb and forefinger.

The “Golf Grip” method of holding the tool is used for more aggressive operations such as grinding a flat surface or using cutoff wheels.

For performing precision tasks a separate nose piece is available in some kits. It has a tapered shape which allows the user to pinch the nose piece comfortably between thumb and forefinger. It provides an excellent line of sight for performing detailed etching, carving and engraving work.

WARNING

 

! CAUTION

Whenever you hold the tool, be careful not to

 

cover the air vents with your hand. This blocks the

 

 

air flow and causes the motor to overheat.

Operating Speeds

To select the right speed for each job, use a practice piece of material.

NOTE: Speed is affected by voltage changes. A reduced incoming voltage will slow the RPM of the tool.

SLIDE "ON/OFF" SWITCH

The tool is switched "ON" by the slide switch located on the topside 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

attachments such as the Dremel Multi-Saw and Dremel Planer.

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.

You can refer to the charts on page 17, 18, 19 and 20 to determine the proper speed, based on the material being worked and
