2. Screw the accessory onto the mandrel.

Speed Control

To select the right speed for each job, use a practice piece of material. Experiment to find the best speed for the accessory and the job. Use the indicator mark above the speed control dial (H) to set the speed. The speed control dial (H) is numbered from 1 to 6.

For example, a speed setting of 1 is approximately 8,000 RPM, and a speed setting of 6 is approximately 35,000 RPM. Refer to the Speed Dial Settings table to determine the proper speed based on the material being worked and the type of accessory.

Speed Setting for Rotary Accessories

Rules of Operating Speeds

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 Speed Dial Settings tables. You can quickly learn that a slower or faster speed is more effective at different speeds.

When working with a scrap piece of plastic, find the optimum working speed without melting the workpiece. The friction of the tool generates heat and causes plastic to melt.

Slow-speed operation (15,000 RPM or less) is usually best for polishing operations using felt polishing accessories and for delicate work. Use lower speeds to avoid wire discharge. Allow the tool to do the work for you when using lower speed settings.

Higher speeds are better for drilling and cutting in wood. Hardwoods, metals, and glass also require high-speed operation.

NOTE:

• Plastic and materials that could melt at low temperatures should be cut at low speeds.
• Soft wood should be cut at high speed.
• Aluminum, tin, copper, lead, and zinc alloys may be cut at any speed, depending on the type of cutting being done. Use paraffin or other suitable lubricants on the cutter to prevent the cut material from adhering to the cutter.

Cutting Guide

The cutting guide comes completely assembled and is ready to use on a variety of materials up to 20mm thick. Always hold the tool firmly, using slow, steady pressure to guide the tool through your work. The speed of the tool will do the work.

IMPORTANT: Always cut in a clockwise direction, except when following a template (e.g., an outlet box), then cut in a counter-clockwise direction.

Installation Instruction Of The Cutting Guide Attachment

1. Remove the collet nut and then the housing cap from the end of your tool.
2. Place the collet nut loosely on the end of the tool.
3. Tighten the collet nut.
4. Thread the Cutting Guide Attachment onto the exposed housing threads on the tool.
5. Adjust the attachment to the desired cutting depth.

Shield Ro

The shield deflects debris, sparks, and dust away from the user, supporting various applications including cutting, sanding, grinding, and polishing. It can be quickly adjusted into position and provides easy access to accessories. It is designed for both left-hand and right-hand grip positions.

Installation Instruction:

1. Remove the housing cap A from the end of the tool and set it aside. The original housing cap must be reinstalled when this attachment is not used.
2. Screw the Shield onto the tool using the lock nut B.
3. Position the Shield such that it will redirect debris, sparks, and dust away from the user, using the positioning tabs C.

Using The Shield Ro

Always turn the tool off before adjusting position or changing accessories. The Shield can be quickly positioned and repositioned with a turn to the right or left.

Flexible Driver Attachment

Safety Rules for Flexible Driver:

• Do not operate the flexible shaft with a sharp or multiple bends. Ensure there are no sharp residual bends or kinks before operation.
• Over-bending the shaft can generate excessive heat on the jacket or hand piece and may cause the Flexible Driver to disengage from the tool.
• The minimum recommended bend radius is 6".
• Always hold the hand piece firmly in your hands to prevent twisting.
• Not for use with router bits or other large diameter bits (1" or larger). Large diameter bits can cause kickback and loss of control.
• Do not remove the end ferrule while the tool is running, as the cable can become loose and whip around uncontrollably.
