is danger of contacting hazardous contaminants.
Clean and disinfect first, then inspect. Failure to follow
this warning can cause inhalation or skin absorption
of the contaminant and result in serious personal
injury or death.
Never substitute, modify, add, or omit parts. Use only
exact replacement parts in the configuration as speci-
fied by the manufacturer. Failure to follow this warning
can result in serious personal injury or death.
