CONTROLS - Optional Gauges maximum engine oil temperature recommended by the engine manufacturer. (See the Engine Operation and Maintenance Manual for details.) NOTE may cause damage to the engine. In- spect the filter and replace if necessa- ry. Holes in the paper element render an air cleaner useless and may cause the Air Filter Restriction Gauge to give a false reading, even if the element is clogged. Replace the element if it is damaged. The maximum allowable restriction could vary according to the type or make of the engine. Consult the en- gine manufactures manual or engine dealer for fuel restriction specifica- tions.
3 Manifold Pressure Gauge This gauge indicates the pressure in the intake manifold. The pressure in the manifold is directly related to the turbo output and is related to the engine power output. Engine, Oil Pressure Air Filter Restriction Indicator or Gauge It is important to maintain oil pressure within acceptable limits. If oil pressure drops below the minimum psi a red warning light in the gauge will turn on, the Stop Engine light will come on and an audible alarm tone will sound. If the pressure indicated by your manifold pressure gauge goes down, there may be something wrong with your engine. Have it checked by a qualified service person.
This gauge indicates the condition of the engine air cleaner and is measured by inches of water (H2O). A clean filter should register 7 in. H2O (may vary with system design) and a filter whose life is over will register approximately 25 in. H2O. Engine, Oil Temperature The Engine Oil Temperature gauge indicates the engine oil temperature. Fuel Pressure Gauge Your vehicle may also have a fuel pressure gauge. This should not to be confused with the standard fuel level gauge of the fuel tank. CAUTION Continued operation with the Air Filter Restriction Gauge reading 25 in. H2O If the oil temperature exceeds the maximum limits, a red warning light in the gauge will turn on.
