Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly main- tained tools, with sharp cutting edges are less likely to bind and are easier to control. Any alteration or modification is a misuse and may result in a dangerous condition.
Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools. Develop a periodic maintenance schedule for your tool.
Use only accessories that are recom- mended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.
Service
Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified per- sonnel could result in a risk of injury. For example: internal wires may be misplaced or pinched, safety guard return springs may be improperly mounted.
When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance Instructions may create a risk of electric shock or injury. Certain cleaning agents such as gasoline, carbon tetrachlo- ride, ammonia, etc. may damage plastic parts.
SAFETY RULES FOR ROTARY TOOL
Accessories must be rated for at least the speed recommended on the tool warning label. Wheels and other accessories run- ning over rated speed can fly apart and cause injury.
Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will make exposed metal parts of the tool "live" and shock the operator. If cutting into existing walls or other blind areas where electrical wiring may exist is unavoidable, disconnect all fuses or circuit breakers feeding this work- site.
Do not operate the flexible shaft with a sharp bend. Over bending the shaft can generate excessive heat on the jacket or hand piece. The recommended minimum is 6" radius.
Always disconnect the power cord from the power source before making any adjustments or attaching any acces- sories. You may unexpectedly cause the tool to start leading to serious personal injury.
Be aware of the switch location, when placing the tool down or when picking the tool up. You may accidentally activate the switch.
Always hold the hand piece firmly in your hands during the
Always wear safety goggles and dust mask. Use only in well ventilated area. Using personal safety devices and working in safe environment reduces risk of injury.
After changing the bits or making any adjustments, make sure the collet nut and any other adjustment devices are secure- ly tightened. Loose adjustment device can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.
Do not reach in the area of the spinning bit. The proximity of the spinning bit to your hand may not always be obvious.
Allow brushes to run at operating speed for at least one minute before using wheel. During this time no one is to stand in front or in line with the brush. Loose bristles or wires will be discharged during the
Wire and bristle brushes must never be operated at speeds greater than 15,000/min. Direct the discharge of the spinning wire brush away from you. Small particles and tiny wire fragments may be discharged at high velocity during the “cleaning” action with these brushes and may become imbedded in your skin. Bristles or wires will be discharged from the brush at high speeds.
Carefully handle both the tool and individ- ual grinding wheels to avoid chipping or cracking. Install a new wheel if tool is
