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

WARNING
Use of this tool can generate and/or disperse 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.
Lead from lead-based paints,
Crystalline silica from bricks and cement and other masonry products, and
Arsenic and chromium from chemically-treated lumber.
sure your extension cord is in good
condition and is a 3-wire extension cord which has a
3-prong grounding type plug and matching
receptacle which will accept the machine’s plug.
When using an extension cord, be sure to use one
heavy enough to carry the current of the machine.
An undersized cord will cause a drop in line voltage,
resulting in loss of power and overheating. The table
shows the correct gauge to use depending on the
cord length. If in doubt, use the next heavier gauge.
The smaller the gauge number, the heavier the cord.
