MAINTENANCE

Clean Cab Floor
--- as required
IMPORTANT: When cleaning the cab floor with tap
water, spray the floor only. Take care not to splash
the surrounding area. Do not increase water spray
speed by restricting the hose end, and do not use high
pressure steam for cleaning. Be sure to completely
remove any moisture from the surrounding area.
1. Park the machine on solid and level surface. Lower the
bucket to the ground. Before cleaning, stop the engine.
Protect the air conditioner in-cab air suction port and the
foot air vent with covers (1) and (2) stored in the pocket
behind the backrest.
2. Remove screws (3) under the floor mat. Remove
circulating air filter (outside) cover (4). Remove the
circulating air filter (outside) from circulating air filter
(outside) cover (4). Install cover (1) with screws (5) in the
position where the circulating air filter was installed.
Secure circulating air filter (outside) cover (4) with screws
(3). Remove foot air vent holding screws (6). Attach cover
(2) onto the foot air vent and secure it with screws (6).
IMPORTANT: Never fail to do this preparation work.
Failure to do so may result in damage/failure of the air
conditioner.
3. Sweep the cab floor clean using a brush, and brush dust
from the cab floor while spraying water.
4. When cleaning the floor mat, sweep dust (water) along
the grooves on the floor mat.
5. When cleaning after removing the floor mat, sweep dust
(water) through two cleaning holes.
6. After cleaning, remove covers (1) and (2) from the air
conditioner in-cab suction hole and the foot air vent
while following the above steps in reverse. Install
the circulating air filter. (Refer to the descriptions for
Clean and Replace Circulating Air Filter and Fresh Air
Filter.) Store covers (1) and (2) in the pocket behind the
backrest.
IMPORTANT: If the A/C is operated without removing the
cover, the A/C will not operate efficiently so that its
cooling ability is reduced.
