Recommended Operating Temperature
1. In applications where low oil temperatures may exist (below -20° F), an external heating system may
be required.
2.
A symptom of excessively low oil temperatures is hydraulic pump/PTO operation but no fluid flow from
tank.
Hydraulic reservoir oil temperatures must not exceed 180° F or damage to crane
may occur. This may affect crane warranty.
