Cleaning And Replacement Of Air Intake Filter Element - Hitachi HISCREW V PLUS NEXT Series Instruction Manual

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 HISCREW capacity and, in
the worst case, the damage of the air intake filter ele-
ment.

① P ress the STOP button.
② Disconnect the power.
③ Open the front door and wait until the oil separator
tank internal pressure gauge reads 0 MPa.
④ 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.
⑤ Lightly pat the filter element to remove larger dust,
and then clean it with air-blow from inside.
⑥ Wipe dust or stains off of the air intake filter hous-
ing and inside the air intake filter cover.
⑦ Push the air intake filter element in its housing firm-
ly as it was before.
⑧ In this state snap the 4 cover fittings on to fix the
cover onto the housing.
CAUTION
● 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 HISCREW installed,
and take effective measures that will enable
the HISCREW to suck the fume-less and
soot-less air. For example, provide a suction
duct or re-select a cleaner installation loca-
tion.
