SAFETY RULES
1
WARNING
For your own safety, read and understand all warnings and operating instructions before using any tool or equipment.
WARNING
Some dust created by operation of power tool contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. To reduce your exposure to these chemicals: work in a well ventilated area and work with approved safety equipment. Always wear OSHA/NIOSH approved, properly fitting face mask or respirator when using such tools.
WARNING
Failure to follow these rules may result in serious personal injury. Remember that being careless for even a fraction of a second can result in severe personal injury.
WORK PREPARATION
• Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, bracelets or other jewelry which may get caught in moving parts of the tool.
• Nonslip protective footwear is recommended.
• Wear protective hair covering to contain long hair.
• Wear eye and hearing protection. Always use safety glasses. Eye protection equipment should comply with ANSI Z87.1 standards. Hearing equipment should comply with ANSI S3.19 standards.
• Wear face mask or dust mask if operation is dusty.
• Be alert and think clearly. Never operate power tools when tired, intoxicated or when taking medications that cause drowsiness.
WORK AREA PREPARATION
• Keep work area clean. Cluttered work areas and benches invite accidents.
• Work area should be properly lighted.
• Do not use the machine in a dangerous environment. The use of power tools in damp or wet locations or in rain can cause shock or electrocution.
• Three-prong plug should be plugged directly into properly grounded, three-prong receptacle.
• Use the proper extension cord. Make sure your extension cord is in good condition. It should have grounding prong and should be of the correct gauge.
• Keep children and visitors away. Your shop is a poten­ tially dangerous environment. Children and visitors can be injured.
• Make your workshop childproof with padlocks, master switches or remove switch keys to prevent any uninten­ tional use of power tools.
TOOL MAINTENANCE
• Turn the machine "OFF", and disconnect the machine from the power source prior to inspection.
• Maintain all tools and machines in peak condition. Keep tools sharp and clean for best and safest performance.
• Follow instructions for lubricating and changing accessories.
• Check for damaged parts. Check for alignment of moving parts, binding, breakage, mounting and any other condition that may affect tool's operation.
• Poorly maintained tools and machines can further damage the tool or machine and/or cause injury.
• A guard or any other part that is damaged should be repaired or replaced. Do not perform makeshift repairs.
TOOL OPERATION
• Avoid accidental start-up. Make sure that the tool is in the “OFF” position before plugging in.
• Use the right tool for your job. Do not force your tool or attachment to do a job for which it was not designed.
• Disconnect tool when changing parts.
• Don't force the workpiece on the machine. Damage to the machine and/or injury may result.
• Never leave tool running unattended. Turn the power off and do not leave tool until it comes to a complete stop.
• Do not overreach. Loss of balance can make you fall into a working machine, causing injury.
• Never stand on tool. Injury could occur if the tool tips, or if you accidentally contact the cutting tool.
• Know your tool. Learn the tool’s operation, application and specific limitations before using it.
• Use recommended accessories. Use of improper accessories may cause damage to the machine or injury to the user.
• Handle workpiece correctly. Keep hands away from moving parts.
• Turn tool off if it jams.
• Do not stand in front of the bench grinder when starting it. Stand to one side and turn the bench grinder ON. Wait at the side for one minute until the grinder comes up to full speed. There is always a possibility that debris from a damaged grinding wheel may be discharged toward the operator.
• Sparks and debris are normally produced during grinding operations. Be sure that there are not any flammable materials in the vicinity. Frequently clean grinding dust from the back of bench grinder.
• Replace a cracked or damaged grinding wheel immediately. A damaged wheel can discharge debris at a high velocity towards the operator.
Carefully handle the grinding wheel since it is abrasive. Prior to replacing a grinding wheel, check it for cracks. Do not remove the labels from a grinding wheel.
• Never start the grinder when the wheel is in contact with the workpiece.
• Secure work. Always hold workpiece firmly against the work rest.
• Do not use the bench grinder if the flange nut or clamp
SAFETY RULES
nut is missing or if the spindle shaft is bent. Frequently clean grinding dust from beneath grinder.
• Tighten the spindle nut just enough to hold the grinding wheel firmly to the bench grinder. Do not overtighten, Excessive clamping force can damage the grinding wheel.
• Adjust distance between wheel and work rest to maintain 1/16 in. or less separation as the diameter of the wheel decreases with use. The value of
2
separation used in the marking is to be the separation recommended by the manufacturer but shall not be more than 1/8 in.
• Only use the wheel flanges provided with the grinder. When selecting a replacement grinding wheel, verify that the grinding wheel has a higher RPM rating than the maximum RPM of the bench grinder.
• Never force the workpiece against a grinding wheel, especially if the wheel is cold. Apply the workpiece slowly, allowing the grinding wheel an opportunity to warm up. This will minimize the chance of wheel breakage.
• Never use the bench grinder with the wheel guards removed.
• Do not grind using the sides of the grinding wheels.
CAUTION: Think safety! Safety is a combination of opera­tor common sense and alertness at all times when tool is being used.
WARNING
Do not attempt to operate tool until it is completely assembled according to the instructions.
