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.

Figure 53. Hydraulic fluid reservoir sight glass (rear access panel removed for photo clarity).

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.
