Disassembled and inspected Hitachi Koki high-pressure air compressor EC1445H2, 12L, approx. 5 minutes 50 seconds

This is a Hitachi Koki EC1445H2 high-pressure air compressor.
It has been disassembled and inspected before listing.
This product has a 12L tank.
All bearings have been cleaned and greased.
The time until shutdown was measured 3 times before listing:
5 minutes 45 seconds, 5 minutes 47 seconds, and 5 minutes 50 seconds.
There are some scratches and dirt that could not be removed.
While there may be some slight pressure loss, there is no audible air leak or leak that would cause immediate restart.
I left it for about an hour to observe, and it did not restart.
There is a crack in the cover as shown in image 3.
It has been reinforced with welding pins from the back as shown in image 4.
The normal pressure gauge was malfunctioning, so it has been replaced with a new aftermarket one.
The ground wire is missing.

As this is an old machine, we cannot offer any warranty. Thank you for your understanding.
Please confirm the operation upon arrival and complete the transaction.
Thank you for viewing.
