Joystick control system Preheater system Points to remember when troubleshooting How to use the troubleshooting tables Engine starts with difficulty (starting always takes time) Engine won't start Engine won't crank Engine cranks but no exhaust gases come out (no fuel injection) Exhaust gases come out, but the engine does not start (fuel injection is present) Engine revs unevenly (poor revs) Engine stops during operation Engine runs uneven Exhaust gases are black Excessive oil consumption (or exhaust gases are blue) Oil gets dirty quickly Excessive fuel consumption Oil in the coolant or splashing or low Coolant level The oil pressure warning light comes on The oil level is rising The coolant temperature becomes excessively high (overheating) Extraneous noise is heard Excessive vibration How to use the troubleshooting tables Engine starts with difficulty (starting always takes time) Checking and adjusting Regulatory tables Table of standard values ??for the engine Chassis
