Carefully handle both the tool and individual surface grinding wheels to avoid chipping or grinding or surfacing. 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.
Do not use surface grinding wheel that is larger than the maximum recommended size for your tool. The guard for a concrete surfacer is limited to the rated size of the machine, use of larger or unauthorized wheel accessories may lead to injury.
Only use dry diamond surfacing cup wheels with the concrete surfacer. The concrete surfacer is not intended for use with standard grinding, cut off, cup wheels or wire brushes. Use of other accessories may cause injury.
Wear proper apparel while using a concrete surfacer. Use thick cushioned gloves and wear ear protectors when using the tool and limit the exposure time by taking frequent rest periods. Face shield or at least safety goggles, dust mask, leather gloves and shop apron capable of stopping small wheel or workpiece fragments. Prolonged exposure to high intensity noise can cause hearing loss. Vibration caused by surface grinding action may be harmful to your hands and arms.
Position the cord clear of the spinning surface grinding wheel. Do not wrap the cord around your arm or wrist. If you lose control and have the cord wrapped around your arm or wrist it may entrap you and cause injury.
When removing the surface grinding wheel from the tool avoid contact with skin and use proper protective gloves when grasping the accessory. Accessories may be hot after prolonged use.
Do not run the tool while carrying it at your side. A spinning wheel could become entangled with clothing and injury may result.
Regularly clean the tools air vents by compressed air. Excessive accumulation of powdered metal inside the motor housing may cause electrical failures.
Do not grind or sand near flammable materials. Sparks from the wheel could ignite these materials.
Some dust created by power sanding, sawing, grinding, drilling, and other construction
activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples 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.
