preventing problems. Oil the unit as outlined below.
2.4.1 Oil Types
The type of oil used has great influence on the performance and durability of the unit. When
selecting the oil, special attention should be paid to the temperature characteristics of oil. The

on various types of oil. The specified type oil is provided in a 40cc (gr.) can or plastic container
(minimum supply unit) by the company.
