Since use of as dull tool will degrade efficiency and
cause possible motor malfunction, sharpen or re-
place the tool as soon as abrasion is noted.
2. Inspecting the mounting screws

that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Fail-
ure to do so could result in serious hazard.

dry cloth or a cloth moistened with soapy water.

ner, for they melt plastics.

perature is less than 40°C and out of reach of
