MAINTENANCE INSTRUCTIONS
■
The brushes and commutator in your Heat Gun have
been engineered and matched for many hours of
dependable service Brushes should be checked for wear
at approximately 400 hours of total operation. Replace in
sets when they reach a length of 1/4-inch or less. Brush

openings in the housing.
