Kickback And Related Warnings - Porter-Cable 7800-XE Instruction Manual

p) Do not use accessories that require liquid coolants. using water or other liquid coolants may result
in electrocution or shock.
WARNING: AlWAys use safety glasses. Everyday eyeglasses are not safety glasses. also use face
or dust mask if cutting operation is dusty. always wEar cErtIFIED saFEty EQuIPmEnt:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
WARNING: 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 lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).
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 disburse dust, which may cause serious and
permanent respiratory or other injury. always use nIosH/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.

Kickback and Related Warnings

Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing pad, brush or any other
accessory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the
uncontrolled power tool to be forced in the direction opposite of the accessory's rotation at the point of the
binding.
For example, if a backing pad is snagged or pinched by the workpiece, the edge of the pad that is entering into
the pinch point can dig into the surface of the material causing the wheel to climb out or kick out. the wheel
may either jump toward or away from the operator, depending on direction of the wheel's movement at the
point of pinching.
Kickback is the result of power tool misuse and/or incorrect operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position your body and arm to allow you to resist
kickback forces. always use auxiliary handle, if provided, for maximum control over kickback or torque
reaction during start-up. the operator can control torque reactions or kickback forces, if proper precautions
are taken.
b) Never place your hand near the rotating accessory. accessory may kickback over your hand.
