2. Inspection and Adjustment IMPORTANT: If the coolant water runs short quickly or when the radiator runs short of water with the Coolant recovery tank level unchanged, water may be leaking or the air tightness may be lost. Increase in the Coolant recovery tank water level during operation is not abnormal. The increased water in the Coolant recovery tank returns to the radiator when the engine is cooled down. If the water level is normal in the Coolant recovery tank but low in the radiator, check loosened clamping of the rubber hose between the radiator and Coolant recovery tank or tear in the hose. Standard Engine: The radiator shall be filled up. (Unit:
liter) Engine coolant water capacity may differ from the above volume depending on an engine installed on a machine unit. (5) Fuel pipe and coolant water pipe inspection and maintenance Check the rubber hoses for fuel and coolant water pipes cracked. If the cracked hose is found, replace it with new one. Check the loosened clamp. If found, tighten it. (6) Inspection and adjustment of governor lever and accelerator Make sure the accelerator of the machine unit can be operated smoothly before starting the engine. If it feels heavy to manipulate, lubricate the accelerator cable joints and pivots.
Adjust the accelerator cable if there is a dislocation or excessive play between the accelerator and the governor lever. Refer to 3.2.3. (7) Warning lamp & instruments function check Before and after starting the engine, check to see that the alarm function normally. Failure of alarm cannot warn the lack of the engine oil or the coolant water. Make it a rule to check the alarm operation before and after starting engine every day. Refer to each manual for machine units in details. 2.2.2 inspection after initial 50 hours operation Be sure to check the following points after initial 50 hours operation, thereafter every 250 hours or 3 months operation.
(1) Lube oil and filter replacement (1st time) When an engine is still hot, be careful with a splash of engine oil which may cause burns. Replace engine oil after the engine oil becomes warm. It is most effective to drain the engine oil while the engine is still warm. 25 Model Coolant water volume In an engine 3TNV82A 1.8 3TNV84(T) 3TNV88 2.0 4TNV84(T) 4TNV88 2.7 4TNV94L 4TNV98(T) 4.2 4TNV106(T) 6.0 No. Inspection Item (1) Lube oil and filter replacement (2) V-belt tension check
