Oil Fill Procedure for Vertical Type
[1] Remove the filler plug. For frame sizes other than
models other than frame size 6255, 6265
, remove the air vent plug to release air.
[2] Pour oil into the oil filler port, keeping an eye on the oil gauge to check the oil level.
[3] Confirm that the oil level is up to the top red line on the oil gauge.
[4] For frame sizes other than
models other than frame size 6255, 6265
wrap the air vent plug with sealing tape and install it.
[5] Replace the filler plug.

- Only fill oil when the machine is stopped.
- It will take some time for high-viscosity oil to reach a uniform level. Be careful not to fill with too much oil. (If oil is filled above the
top red line, churning heat may raise the temperature.)
- Use the lower red line of the oil gauge as a guideline for the oil level while the machine is running. (The oil level may drop below
the bottom red line immediately after the machine starts. It will return when oil viscosity drops as the machine runs. Therefore, this
is not a problem.)
- For daily oil level management see Table 8-1 on P36.
(5) Draining Procedures
To drain the oil, remove the oil drain plug and the the plug at the bottom of the oil gauge.

(6) Long Term Inactivity
Table 8-9 Long Term Inactivity
Period of
Inactivity
Approximately
1 month
Before resting the machine, change to new oil and run the machine for a few minutes.
1 month or
more
Before resting the machine, flush, fill with rust preventing oil and run for a few minutes under no load.
When resuming operation after a long period of inactivity, change to new oil because the existing oil may degrade.
