Precautions for the air-cooled pump unit
・ When removing the radiator, drain oil first, and remove the outlet/inlet pipes, four supporting bolts (6 x 15), two pan head screws on the fan side
(4 x 50), fan, and then motor, in this order. If a large amount of oily dust is attached to the radiator, soak in a warm water solution with dissolved
neutral detergent, and rinse in water. After that, blow compressed air on it.
・ Clean oil deposit using solvent (Trichloroethylene) approximately once a year
(Deteriorated oil will be dissolved gradually in the solvent. Leave solvent inside for approximately 30 minutes).
・ When the detector indication ring turns yellow, remove the cover on top of the filter,
and clean the element using light oil, etc.
Precautions for the water-cooled pump unit
・ Check that water is always running in the oil cooler pump unit.
・ If there is a risk of water freezing due to being in cold regions, a time of extreme
cold, or when interrupting operation, remove the drain plug of the pump unit, and
drain the water from it.
・ Since accumulated water deposit inside the pump unit could result in a decrease in
cooling function, clean the cooling water conduit once a year.
Note : When cleaning the water conduit, remove the water chamber covers on both sides.

● When using the product at especially low temperatures (approximately -30ºC to 0ºC) or high temperatures (approximately 40ºC or more), heat or cold-
resistant lubricating oil and applicable internal parts are required. For details, consult us in advance.
● For purchase of special traction drive oil, contact us or any of the ENEOS Corporation offices.
■ Speed change section
For special traction drive oil, the oil lifespan is extremely long, and the replacement interval is very long.
＊ For the replacement interval, refer to the above table.
■ Speed reduction section
Replace lubricating oil described in the above table at the specified replacement interval.
Note 1. For lubricating oil supplied at shipping, contact us accordingly.
2. The oil replacement interval differs depending on conditions of use. In particular atmospheres subject to high humidity and/or active gas, shorten the replacement interval described
in the above table.

3-1 Special Lubricating Oil
Lubricating oil plays an important role in power transmission, and also has various effects on burn, wear, and/or rust prevention, and/or cooling.
Since lubricating oil greatly influences the performance of the product and product life, be sure to use the special traction drive oil for the speed change
section. The type of lubricating oil differs between the speed change and speed reduction sections. In the event that different types of oil are used,
sufficient performance may not be attained, or extension of the product life may be greatly influenced.
