Troubleshooting for Too Much Weight/Abnormal Noise on Pulling Out/Pushing In the
Drawer Unit
Symptom
It is very difficult to pull out/push in the drawer unit, and/or noise is made when this is done.
Cause
Grease on the positioning pins decreases over time.
Solution
Apply grease (Barrierta S552R) to the drawer unit positioning pins when the amount of grease gets
too low.
• As a rough figure, the grease needs to be applied every 2000 times the drawer unit is
opened.
Procedure
1. Press the release levers and pull out the drawer unit [A] all the way.
