Cleaning of air conditioner Recirc/Fresh
air filters
k When using compressed air, put on protec-
tive glasses, dust mask and other protec-
tive gears since dirt will scatter and it can
cause serious injury or death.
1. Cleaning of recirculated air filter
1) Remove wing bolt (1) of the inspection
hole at the inside left rear bottom of the
operator's cab and remove the recircu-
lated air filter.
2) Clean the filter with compressed air. If it is
stained with oil or very dirty, wash it in
water and neutral detergent. After wash-
ing, dry sufficiently and then install.
If the dirt clogging the filter cannot be
removed with compressed air or water,
replace the filter with new one.
a Since the recirculated air filter has
directional properties, install it with
the projection side toward the front of
the machine.
2. Cleaning of fresh air filter
1) Unlock cover (2) at the left rear of the
operator's cab with the key (starting switch
key). While holding cover (2) open with
your hand, take filter (3) out of the cover.
2) Clean the filter with compressed air. If it is
stained with oil or very dirty, wash it in
water and neutral detergent. After wash-
ing, dry sufficiently and then install.
If the dirt clogging the filter cannot be
removed with compressed air or water,
replace the filter.
3) After cleaning filter (3), return it and close
the cover. Then, lock the cover with the
key (starting switch key). Take care not to
forget to pull out the key (starting switch
key).
a Since fresh air filter (3) has directional
properties, insert it with longer side
(L) ahead. If it is inserted with shorter
side (S) ahead, cover (2) cannot be
closed.
