•
Never use grinding wheels over 25.4 mm (1") in diameter. The tool's high speed
could cause them to fly apart causing injury.
•
Do not put the tool down while it is running.
•
Do not place the tool on a dusty surface. Dust entering the motor could interfere
with its performance.
1. Ensure the accessory is securely clamped in the collet. Plug in the tool.
2. Hold the tool firmly. Press the on-off switch.
3. Adjust the rotating speed with the speed adjustment thumbwheel. To select the
optimal speed for the job, use a piece of scrap material for a trial run. Vary the
speed and check the performance of that particular accessory on that particular
piece of material. In general, higher speeds are better for carving, cutting, routing,
and shaping wood. Hardwoods, metals, and glass all require high speed as does
drilling. Lower speeds usually work better for some plastics and other materials
that may melt in the heat generated by high speeds. They are also better for
polishing with the felt wheel accessories. You may also find lower speeds
preferable in extremely delicate carving.
4. For most jobs, the rotary tool works best at the top speed. Be careful not to place
too high a load on the tool at low speed. This could burn out the motor
prematurely.
6. Accessories
6.1 Overview
Radial Bristle Brush
•
Good for general purpose cleaning
This bristle brush is ideal for general cleaning and polishing, especially in hard-to-reach
places, such as slotted surfaces. It can also be used for cleaning hard plastic or
aluminium such as graphite golf clubs or aluminium wheels.
Felt Wheels and Mandrel
•
Good for polishing
Felt wheels and tips should be used with a polishing compound - similar to polishing a
car. For best results, do not use these accessories at speeds higher than 15 000 rpm.
Aluminium Oxide Grinding Stones
•
Good for sharpening and grinding
Use the grinding stones for sharpening lawn mower blades, screwdriver tips, knives
scissors, chisels and other cutting tools, to remove flash from metal castings, deburring
any metal after cutting, smoothing welds joints, grinding off rivets and removing rust.
These grinding stones can be resharpened with a dressing stone.
Cut-Off Wheels
•
Good for cutting and slicing
These thin discs of fiberglass are used for slicing, cutting and other tasks.
