If no oil pressure is indicated STOP the engine. Engine damage could result.
Engine Oil Pressure - The oil pressure should be greatest after starting a cold engine. The typical oil pressure range for engines running at rated rpm and operating temperature with SAE 10W30 or 15W40 oil is 240 to 480 kPa (35 to 70 psi).A lower oil pressure is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:1. Remove the load.2. Reduce engine rpm to low idle.3. Check and maintain the oil level. Water (Coolant) Temperature - Typical temperature range is 71 to 96° C (160 to 205° F). The maximum allowable temperature with the pressurized cooling system at 48kPa (7 psi) is 103° C (217° F) with the cooling system pressurized. Higher temperatures may occur under certain conditions. The water temperature reading may vary according to load. The reading should never exceed the boiling point for the pressurized system that is being used.If the engine is operating above the normal range and steam becomes apparent, perform the following procedure:1. Reduce the load and the engine rpm.2. Inspect the cooling system for leaks.3. Determine if the engine must be shut down immediately or if the engine can be cooled by reducing the load. Ammeter - This gauge indicates the amount of charge or discharge in the battery charging circuit. Operation of the indicator should be to the right side of "0" (zero). Tachometer - This gauge indicates engine rpm. The engine can be operated at high idle without damage, but should never be allowed to overspeed. Overspeeding while downshifting, going downhill, etc, can result in serious damage to your engine.
To help prevent engine damage, never exceed the high idle rpm. Overspeeding can result in serious damage to the engine. The engine can be operated at high idle without damage, but should never be allowed to exceed high idle rpm.
The high idle rpm and the full load rpm are stamped on the Information Plate/Decal Engine Oil Temperature - This gauge indicates engine oil temperature. Maximum oil temperature at rated rpm with a full load is 104° C (220° F).Higher than normal oil temperature indicates a heat problem has occurred in the lubrication and/or cooling system. Higher than normal oil temperatures can damage the cylinder heads, the liners, the pistons and the crankshaft bearings. Fuel Level - This gauge indicates the fuel level in the fuel tank. This electrically operated fuel level gauge registers only when the "START/STOP" switch is "ON". Fuel Pressure - This gauge indicates fuel pressure to the fuel injection pump from the fuel filter. The indicator should register in the "NORMAL" (green) range. The minimum fuel pressure is 160 kPa (23 psi) when the engine is equipped with a numerical gauge and the engine is under load. A drop in fuel pressure usually indicates dirty fuel filters or plugged fuel filters. Service Hour Meter - This gauge indicates the total number of clock hours that the engine has operated.
