PRESSURE CHECK
The pressure gauge located on the front panel is used to measure the pressure in the lubricating
circuit.

conditions; this value is largely affected by oil viscosity and temperature so when the machine is
started pressure is usually high and then tends to decrease and become stable as the machine
warms up with operation.
If pressure drops too low at high temperatures this may be due to problems with the cooling system

The water temperature must conform with the values given in Section 1 –TECHNICAL
