Special notes
This type of power unit works at S3 duty cycle, i.e., intermittent duty, 1 minute on-load and 9 minutes off-load.
Clean all the hydraulic parts concerned before mounting the power unit.
Viscosity of the hydraulic oil should be 15-68 cst, which should also be clean and free of impurities. N46 hydraulic oil is recommended.
Check the oil level in the tank after the initial operation of the power unit.
Oil changing is required after the initial 100 operation hours, afterwards every 3000 hours.
