cause premature failure. Not regularly cleaning
the AS170 will affect the tools warranty.

Brushes
The AS170 is fitted with Auto-cut off brushes. When

CAUTION: The V-Belt should be re-tensioned
after the first 5 hours of use.
To access these items, remove the 4 screws holding
the plastic cover on the right side of the tool (see
fig.14). Inspect the belt for correct tension and signs
of damage. If tensioning is required, loosen the the
tension idler nut (one turn only). Slide the tension
idler outward to increase the tension to the value
noted in the General Specifications in Section
3 and re-tighten. If belt replacement is required,
loosen the tensioner idler, replace the belt and re-
tension the idler as specified.
