MAINTENANCE
Every 50 hours of operation blow compressed air through the motor while running at no load to clean out
accumulated dust. (If operating in especially dusty conditions, perform this operation more often.)
KEEP TOOL CLEAN
Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft
damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the
material.
Wear safety glasses while using compressed air.
Clean the vacuum swivel connector as too much dust will keep it from turning freely.
THE CARBON BRUSHES
The carbon brushes are a normal wearing part and must be
replaced when they reach their wear limit. When the brushes are
worn to a length of 1/4", they should be replaced.
NOTE: Checking and replacing the carbon brushes should be entrusted to a qualified service center.
If the replacement of the power supply cord is necessary, this has to be done by the manufacturer or
their agent in order to avoid a safety hazard.
WARNING: All repairs must be entrusted to an authorized service center. Incorrectly performed repairs
could lead to injury or death
