METHOD FOR CHECKING DOOR LATCH
1.
Keep the door open.
2.
Check if the grease in the latch dried out.
If the amount of grease is low or there is no more grease,
coat the inside of the latch with grease from portion (1).
REMARK
If there is no more grease inside the latch, the movement of the door will become poor because of dust inside
the latch, and the handle may become heavy when you open the door.
METHOD FOR CHECKING DOOR LOCK STRIKER
Measure wear (A) of the door lock striker.
If wear (A) is 0.5 mm or more, replace the door lock striker.
If you use it as it is, its play increases and can cause breakage
of the hinge and lock door.
