4-1 Lubricating oil to be used
Use industrial lubricating oil in the range from 32 to
1300 mm
2
/s of ISO viscosity.
Do not use any lubricating oil other than that
which has been recommended.
Use lubricating oil of the same grade made by the
same manufacturer.
4-2 Refilling lubrication oil
When the oil in the tank reaches the
Ｌ
level on the oil
level gauge provided, refill the tank with more oil, up to
the
Ｈ
level, from the refill port on the pump flange.
Use new lubricating oil. If lubricating oil contains
any foreign substances, clogging may occur,
causing the pump to stop discharging oil.
Refill it through the refill port that you find above the
pump flange.
Keep checking the oil level gauge provided when refilling
the tank with oil.
If lubricating oil overflows or leaks, wipe off the
overflowing or leaking oil.
