THE MOST COMMON HYDRAULIC PROBLEMS ARE:
1. LOW LEVEL OF HYDRAULIC OIL IN THE RESERVOIR: The reservoir holds 13.5 U.S. gallons
(51 Liters). The level should be 2"(50mm) below the top of the reservoir.
2. CONTAMINATION IN THE HYDRAULIC OIL: The oil and the filter should be changed at
least once a year and any time there is a possibility that contamination has gained access into the
system. For recommended hydraulic oil, SEE SECTION 5.1.
3. LOW PRESSURE CAUSED BY WORN OR DAMAGED PARTS IN THE CYLINDER OR PUMP:
There is a pressure port for a pressure gauge provided on all machines. The port will be on the
manifold or the pressure line between the pump and the valve. A gauge with a minimum capacity
of 3,000 PSI (207 BAR) is required. With the machine.s power off, install the pressure gauge.
Power the machine and place a piece of steel in the shear section and clamp it down with the
hold-down device. Attempt to shear the piece, watching the pressure gauge for a reading. The
system pressure of this machine is 2,700 PSI (185 BAR). The pressure is adjustable by adjusting
the relief valve on the control valve manifold. If the pressure cannot be increased, call your local
dealer or the factory.
