LIFT AGING MODE  - page 39
We suggest to do mechanical aging for 10 minutes after assembly.
LIFT unit moves very quietly.
If there is a noise from LIFT unit operation, most of cases are mechanical 
assembly problems.
To achieve a quiet movement of Lift unit, the assembly is very important.
Please refer the information in the Service manual well.
For example, special grease is used at lead screw part. Please do not apply the 
grease too much or less.
Too much or less grease leads to mechanical trouble. (Mechanical noise, etc.)
We suggest 10 minutes mechanical aging with LIFT AGING MODE after the 
mechanical assembly.
And, please be careful the drawing of the cables in mechanical assembly.
As LIFT motor power is very strong, lead wires will be cut easily if it hook with 
LIFT mechanism.
Please confirm the service manual information once before repair.
