4.3 Oil Level (See Figures 3 and 4)
Check the pump oil level prior to start-up. The reservoir is full

the oil fi ll plug from the cover plate as shown in Figure 3 and add
oil as required.
IMPORTANT: Add oil only when all system components are fully
retracted, or the system will contain more oil than the reservoir
can hold.
