Remove the front door. Unfasten four snap-on fit-
tings on the air intake filter cover, and pull the air
intake filter element out of its housing.
Lightly pat the filter element to remove larger dust,
and then clean it with air-blow from inside.

ing and inside the air intake filter cover.

8.7 Cleaning and Replacement of Air Intake Filter Element
Clean or replace the air intake filter element, as soon as
possible, if the error code of an element clogging
appears on the digital monitor. Failure to do so will
result in the reduction of the
HI
SCREW capacity and, in
the worst case, the damage of the air intake filter ele-
ment.

Press the STOP button and disconnect the
power before proceeding to replace the air
intake filter.
If atmospheric air contains car fumes and
soots from incinerators and boilers, the air
intake filter element will be clogged earlier
than otherwise. If this is the case, check the
atmosphere around the
HI
SCREW installed,
and take effective measures that will enable
the
HI
SCREW to suck the fume-less and
soot-less air. For example, provide a suction
duct or re-select a cleaner installation loca-
tion.
