to provide extra cushion, take frequent rest periods, and limit daily time of use.
• Always hold the tool firmly with both hands for maximum control. Keep proper
footing and balance at all times. This enables better control of the power tool in
unexpected situations.
• Do not restart the cutting operation in the workpiece. Let the tool reach full
speed and carefully re-enter the cut.
• Do not "jam" the cut-off saw blade or apply excessive pressure. Do not
attempt to make an excessive depth of cut.
• Keep your hands away from cutting area. Do not reach under the material being cut.
• Do not use dull or damaged blades. Bent blade can break easily or cause
kickback. Exercise extreme caution when handling the accessories. The
accessories are very sharp. Wear protective gloves when changing cutting
accessories. Accessories become hot after prolonged usage.
• Before scraping, check workpiece for nails. If there are nails, either remove
them or set them well below intended finished surface. Striking a nail with
accessory edge could cause the tool to jump.
• Do not wet sand with this tool. Liquids entering the motor housing are an
electrical shock hazard.
• Never work in area which is soaked with a liquid, such as a solvent or water,
or dampened such as newly applied wallpaper. There is an electrical shock
hazard when working in such conditions with a power tool and heating of the liquid
caused by scraping action may cause harmful vapors to be emitted from workpiece.
• Do not use sandpaper intended for larger sanding pads. Larger sandpaper will
extend beyond the sanding pad causing snagging, tearing of the paper or kick-back.
Extra paper extending beyond the sanding pad can also cause serious lacerations.
WARNING:
ALWAYS use safety glasses. Everyday eyeglasses are NOT safety
glasses. Also use face or dust mask. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CPA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NOSH/OSHA respiratory protection.
WARNING:
Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the state of California to cause
cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products,
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.
• Avoid prolonged contact with dust from power sanding, sawing, grinding,
drilling, and other construction activities. Wear protective clothing and wash
exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or
lay on the skin may promote absorption of harmful chemicals.
WARNING:
Use of this tool can generate and/or disperse dust, which may cause
serious and permanent respiratory or other injury. Always use NOSH/OSHA approved
respiratory protection appropriate for the dust exposure. Direct particles away from face
and body.
WARNING:
Always wear proper personal hearing protection that conforms
to ANSI S12.6 (S3.19) during use. Under some conditions and duration of use, noise
from this product may contribute to hearing loss.
Precautions To Take When Sanding Paint
1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of
controlling the contaminated dust. The greatest danger of lead poisoning is to children
and pregnant women.
2. Since it is difficult to identify whether or not a paint contains lead without a chemical
analysis, we recommend the following precautions when sanding any paint:
