8.4 HYDRAULICS
THE MOST COMMON HYDRAULIC PROBLEMS ARE:
1.
Low level of hydraulic oil in the reservoir: The reservoir holds 12 U.S. gallons (45 Liters). The level
should be 1" 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 5.2.
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 valve manifold or the
pressure line between the pump and the valve. A gauge with a minimum capacity of 3,000 PSI 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.
The pressure is adjustable by adjusting in the relief valve adjustment on the control valve manifold.
If the pressure cannot be increased, call your local dealer or the factory.
