Troubleshooting Information
Replace dust filter
A noticeable deposit of dust at the impeller fan
exhaust indicates a poorly installed or defective
dust filter.
– Raise debris container (1) to half of its travel,
and secure against dropping.
– Unsnap clip fasteners (2) on filter enclosure.
– Swing filter enclosure (3) forward, then lift
off.
– Unfold hand grip (4), pull out, and unlock by
means of a 90-degree turn.
– Remove old dust filter (5).
– Insert new dust filter (6).
– Return hand grip (4) to original position, and
snap into place.
– Install filter enclosure (3), and lock clip fas-
teners (2).
Check rubber sleeve
To prevent filter replacement problems caused
by premature corrosion of the locator pin (7) in
the filter receptacle, a rubber sleeve (9) was in-
stalled on units with S/N 10518 and up.
Defective or missing rubber sleeve (9) should be
replaced or retrofitted (refer to service bulletin
no. 1998-045).
