ADDITIONAL SPECIFIC SAFETY RULES
SAVE THESE INSTRUCTIONS!
1. Hold power tools 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.
2. Verify the direction of rotation before starting the tool. Never
attempt to change direction of rotation while switch is “ON”. To do
so, may damage interlock feature built into switch. Be sure switch is
“OFF” and motor has completely stopped before changing direction of
rotation.
3. Wear eye and hearing protection. Always use safety glasses. Everyday
eyeglasses are NOT safety glasses. USE CERTIFIED SAFETY EQUIPMENT.
Eye protection equipment should comply with ANSI Z87.1 standards.
Hearing equipment should comply with ANSI S3.19 standards.
4. Use of this tool can generate and disburse dust or other
airborne particles, including wood dust, crystalline silica dust and
asbestos dust. Direct particles away from face and body. Always operate
tool in well ventilated area and provide for proper dust removal. Use dust
collection system wherever possible. Exposure to the dust may cause
serious and permanent respiratory or other injury, including silicosis (a
serious lung disease), cancer, and death. Avoid breathing the dust, and
avoid prolonged contact with dust. Allowing dust to get into your mouth or
eyes, or lay on your skin may promote absorption of harmful material.
Always use properly fitting NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure, and wash exposed areas with soap and
water.
