before attempting assembly or operation.
2.
Read and understand all warnings posted on
the tool and in this manual. Failure to comply
with all of these warnings may cause serious
injury.
3. Replace warning labels if they become
obscured or removed.
4.
Do not use this tool for other than its intended
use. If used for other purposes, JET disclaims
any real or implied warranty and holds itself
harmless from any injury that may result from
that use.
5. Always wear ANSI Z87.1 approved safety
glasses or face shield while using this tool.
(Everyday eyeglasses only have impact
resistant lenses; they are
not
safety glasses.)
6. Wear ear protectors (plugs or muffs) if the
noise exceeds safe levels.
7. Wear gloves and protective clothing if
operation produces sparks or flying particles.
Gloves should be tight-fitting, without frayed
fingers or hanging threads. Keep hands and
body away from the working area of tool.
8.
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 paint.
• Crystalline silica from bricks, cement and
other masonry products.
• Arsenic and chromium from chemically
treated lumber.
Your risk of exposure 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 face or dust masks
that are specifically designed to filter out
microscopic particles.
