4-40
LUBRICATE DOOR HINGE
If the door makes a squeaking noise when it is opened or
closed, spray lubricant in through the split in the hinge bushing.
If the bushing is worn, replace the hinge.
CHECK DOOR LATCH
WARNING
If the control lever is touched by accident during checking,
the machine moves off suddenly, and this may lead to seri-
ous injury or death.
Before checking door latch, stop the engine and set the
parking lever securely to the LOCK position.
Check
Hold the door open-locked, and check that there is still grease
inside the latch. If the amount of grease is low or there is no
more grease, coat the inside of the latch with grease from por-
tion (1).
REMARK
If there is no more grease inside the latch, the movement will
become poor because of dust inside the latch, and the handle
may be stiff when opening the door.
CHECK DOOR LOCK STRIKER
If the wear of the door lock striker exceeds 0.5 mm, replace the
striker. If it is used at it is, the play will increase and this may
result in breakage of the hinge or door lock.
