The damper is installed at top and bottom, 2 pieces each on
the R.H. and L.H. doors.

If the door creaks when it opens or closes, spray lubricant

WARNING
It is dangerous if the machine moves by mistake during in-
spection.
Stop the engine and securely set the parking brake lever to
LOCK position (L).
1.
With the door open, check if the grease in the latch dried
out.
2.
If the grease is insufficient or dried out, apply new grease
to inside of the latch through portion (1).
REMARK
If the grease in the latch is dried out, the latch does not
move normally because of dust in it, and the operating ef-
fort of the handle may become heavy when you open the
door.
