PREPARATION FOR INSPECTION AND
MAINTENANCE
When the floor tilt mechanism is used:
CAUTION: Do not open or close the floor tilt
mechanism in daily inspection. The daily inspec-
tion can be performed through the maintenance
cover ports.
CAUTION: When using the floor tilt mechanism,
consult your authorized dealer. If bolts (3) are
removed or installed by unauthorized personnel,
mismatch to ROPS may occur.
When performing inspection and maintenance using the
floor tilt mechanism, park the machine in the following
procedure.
1. After operating the machine, wait the machine to suf-
ficiently cool.
2. Park the machine on solid and level surface.
3. Lower the blade on the ground.
4. After rolling the arm and the bucket in, lower the
bucket a wooden block down to the ground.
5. Face the front attachment straightforward toward the
machine without swinging the front attachment at this
time.
6. Stop the engine. Remove the key from the key switch.
7. Close the cab (optional) door.
8. After loosening two bolts (2) of cover (1) on the front
of the base machine, fully slide the cover upward.
Then, temporarily tighten bolts (2) so that the cover
does not fall.
9. Remove bolts (3) (not covered with resin caps) in the
rear section of the operator's seat.
CAUTION: Be careful. When bolts (3) are re-
moved, the canopy or the cab may come off the
floor.
CAUTION: Be careful that if the floor is tilted
upward while raising the front attachment, the
canopy or cab (optional) may come in contact
with the boom.
