workshop situations etc., and order necessary parts in advance.
(4) Recording
Record the following items to keep contact and prevent malfunction from recurring.
1. Inspecting date, place
2. Model name, Serial number and Record on hour meter
3. Trouble condition, place, cause
4. Visible oil leak, water leak and damage
5. Clogging of filters, oil level, oil quality, oil contamination and looseness.
6. Examine the problems on the basis of monthly operation rate with the last inspection date and records on hour meter.
(5) Arrangement and cleaning in service shop
