OPERATOR SAFETY INSTRUCTIONS
WARNING AVERTISSEMENT ADVERTENCIA
DANGER means: Severe bodily injury or death can occur to you or other personnel if the DANGER statements
found on this machine or in this Operator’s Manual are ignored or are not adhered to. Read
and observe all DANGER statements found in this Operator’s Manual and on your machine.
WARNING means: Injury can occur to you or to other personnel if the WARNING statements found on your
machine or in this Operator’s Manual are ignored or are not adhered to. Read and observe all
WARNING statements found in this
Operator’s Manual and on your machine.
CAUTION means: Damage can occur to the machine or to other property if the CAUTION statements found
on your machine or in this Operator’s Manual are ignored or are not adhered to. Read and
observe all CAUTION statements found in this Operator’s Manual and on your machine.
DANGER: Failure to read the Operator’s Manual before operating or servicing this sanding equipment could result in
injury to the operator or to bystanders and could cause damage to the equipment. Read and observe all
safety statements found in this manual and on the sanding equipment. Make sure all labels, decals, warn-
ings, cautions and instructions are fastened to the equipment. Replace any that are damaged or missing.
You must have training in the operation of this equipment before using it. If the operator is unable to read
this manual, have it explained fully before they attempt to use this equipment.
DANGER: Sanding/finishing wood floors can create an environment that can be explosive. The following safety proce-
dures must be adhered to:
• Cigarette lighters, pilot lights and any other source of ignition can create an explosion when active during
a sanding session. All sources of ignition should be extinguished or removed entirely if possible from the
work area.
• Work areas that are poorly ventilated can create an explosive environment when certain combustible
materials are in the atmosphere, i.e., solvents, thinners, alcohol, fuels, certain finishes, wood dust and
other combustible materials. Floor sanding equipment can cause flammable material and vapors to burn.
Read the manufacturer’s label on all chemicals used to determine combustibility. Keep the work area well
ventilated.
• Spontaneous combustion or an explosion can occur when working with sanding dust. The sanding dust
can self-ignite and cause injury or damage. Sanding dust should be disposed of properly. Always empty
the sanding dust into a metal container that is located outside of any building(s).
• Remove the contents of the dust bag when the bag is 1/3 full. Remove the contents of the dust bag each
time you finish using the equipment. Never leave a dust bag unattended with sanding dust in it.
• Do not empty the contents of the dust bag into a fire.
• Hitting a nail while sanding can cause sparks and create an explosion or fire. Always use a hammer and
punch to countersink all nails before sanding floors.
