Hydraulic Power Units■ Interchangeability between Current and New Models
As of AML1 type motor pump, the design number has changed from 10 to 20 due to change of built-in electric motor.

● Major Changes（1）Mass has been increased in the range of 1.5 - 9.7 kg (Mass ratio 106 - 136%)（2）The body has become larger in general.
（3）Built-in electric motor efficiency class has changed to IE3. Motor specifications have been upgraded in general.

● Interchangeability in Installation
No interchangeability. The following dimensions are different.
