SAFETY RULES FOR ROTARY TOOL (CONTINUED)
dropped while grinding. Do not use a wheel that may be damaged. Fragments from a wheel that bursts during operation will fly away at great velocity possibly striking you or bystanders.
Never use dull or damaged bits. Sharp bits must be handled with care. Damaged bits can snap during use. Dull bits require more force to push the tool, possibly causing the bit to break.
Use clamps to support workpiece when- ever practical. Never hold a small work- piece in one hand and the tool in the other hand while in use. Allow for sufficient space, at least 6", between your hand and the spinning bit. Round material such as dowel rods, pipes or tubing have a tendency to roll while being cut, and may cause the bit to “bite” or jump toward you. Clamping a small workpiece allows you to use both hands to control the tool.
Inspect your workpiece before cutting. When cutting irregularly shaped work- pieces, plan your work so it will not slip and pinch the bit and be torn from your hand. For example, if carving wood, make sure there are no nails or foreign objects in the workpiece. Nails or foreign objects can cause the bit to jump.
Never start the tool when the bit is engaged in the material. The bit cutting edge may grab the material causing loss of control of the cutter.
Avoid bouncing and snagging the wheel, especially when working corners, sharp edges etc. This can cause loss of control and
The direction of feed with the bit into the material when carving, routing or cutting is very important. Always feed the bit into the material in the same direction as the cutting edge is exiting from the material (which is the same direction as the chips are thrown). Feeding the tool in the wrong direction, causes the cutting edge of the bit to climb out of the work and pull the tool in the direction of this feed.
If the workpiece or bit becomes jammed or bogged down, turn the tool “OFF” by the switch. Wait for all moving parts to stop and unplug the tool, then work to free the jammed material. If the switch to the tool is left “ON” the tool could restart unexpectedly causing serious personal injury.
Do not leave a running tool unattended, turn power off. Only when tool comes to a
complete stop it is safe to put it down.
Do not grind or sand near flammable materials. Sparks from the wheel could ignite these materials.
Do not touch the bit or collet after use. After use the bit and collet are too hot to be touched by bare hands.
Regularly clean the tool's air vents with compressed air. Excessive accumulation of powdered metal inside the motor housing may cause electrical failures.
Do not allow familiarity gained from fre- quent use of your rotary tool to become commonplace. Always remember that a careless fraction of a second is sufficient to inflict severe injury.
Do not alter or misuse tool. Any alteration or modification is a misuse and may result in serious personal injury.
This product is not intended for use as a dental drill, in human or veterinary med- ical applications. Serious injury may result.
When using the steel saws, cutoff wheels, high speed cutters or tungsten carbide cutters, always have the work securely clamped. Never attempt to hold the work with one hand while using any of these accessories. The reason is that these wheels will grab if they become slightly cant- ed in the groove, and can kickback causing loss of control resulting in serious injury. Your second hand should be used to steady and guide the hand holding the tool. When a cut- off wheel grabs, the wheel itself usually breaks. When the steel saw, high speed cut- ters or tungsten carbide cutter grab, it may jump from the groove and you could lose control of the tool.
! WARNING Some dust created by power drilling and other construction activities, contains chemi-
cals known to cause cancer, birth defects or other reproductive harm. Some exam- ples of these chemicals are:
• Lead from
• Crystalline silica from bricks and cement and other masonry products, and
• Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.
