G0646/G0647 50/65 Ton Ironworker
Hydraulic System
Fluid Capacity
Hydraulic Reservoir ......... Approx. 15 gal. (60 L.)
The hydraulic system must be maintained on a
regular basis and kept in good operating condition
so that the ironworker can perform safely and at
the rated capacity.
If you have never maintained a hydraulic system
before, WE STRONGLY RECOMMEND that you
read books, get formal training, or seek the help of
a qualified hydraulic service technician.
NOTICE
Failure to perform regular and proper
hydraulic system maintenance and to keep
the hydraulic system in good operating
condition will lead to premature wear of the
moving parts, hoses, and valves, and will
void the warranty.
Use the sight glass mounted on the rear of the
hydraulic reservoir (see Figure 53) to check the
fluid level and temperature. Maintain the fluid level
above the red line on the sight glass.
The operating temperature of the hydraulic fluid
should not exceed 160°F (70°C) with an optimum
operating temperature window of 50–95°F (10–
35°C). If the fluid temperature rises above 160°F,
stop the machine immediately and allow the fluid
to cool down.
If this condition continues during operation, stop
using the machine immediately, then review
Troubleshooting on Page 43. If you still cannot
remedy the problem, contact a qualified hyraulic
service technician or our Tech Support at (570)
546-9663 for assistance.
