We all know that we should pay attention to the operation of diesel forklift trucks, but many people have ignored the correct way to start and turn off the engine, today let's take a look!
1、The starting method
Before starting, check the coolant height, oil and fuel amount, battery electrolyte level, lamp, surface, tire pressure, etc. The driver can start after careful inspection according to the procedures, contents and requirements that need to be checked before starting.
1. Operation method
(1) Tighten the parking brake and put the shift lever in neutral position;
(2) Open the combustion switch and connect the combustion circuit;
(3) Press the clutch pedal with the left foot, gently press the accelerator pedal with the right foot, pull out the choke valve, twist the gasoline engine, and turn the combustion switch key to the starting position to start; Turn the starting knob or button of the diesel engine.
(4) The engine starts, and after the engine idles, release the clutch pedal, maintain low speed operation, and gradually increase the engine temperature. Do not push the accelerator pedal hard, so as to avoid too high engine oil pressure, aggravate engine wear.
2、Precautions
(1) The engine should be preheated at low temperature. Generally, the method of heating water and crankshaft turning can be used to make all lubricating surfaces fully lubricated to prevent the engine from preheating. When the cooler starts in cold conditions, turn the electric fan by hand to prevent the water pump shaft from freezing, turn the gasoline pump rocker arm, and fill the carburetor with gasoline to preheat the engine.
(2) The operation time of the driving machine shall not exceed 5s, and the button shall not be pressed for a long time to prevent damage to the starter and battery. No more than 2 words are started consecutively, each time at an interval of 10-15s. If three consecutive starts are still not good, the diesel forklift repairman should be informed to check and start again after the stock index is cleared.
(3) Prevent starting by delaying, talking back, sliding down a slope or slamming on the clutch pedal to prevent damage and failure of parts.
3、The method of extinguishing
When the diesel forklift truck needs to stop after operation, the gasoline forklift truck only needs to turn off the combustion switch and investigate the shaking of the ammeter pointer to distinguish whether the circuit is blocked. Before stopping the engine, do not step on the accelerator to pump up the car, which not only wastes fuel, but also increases the wear of the engine. If the engine is turned off when the temperature is too high, the engine should idle for 1-2 minutes to cool the parts evenly, and then turn off the combustion switch. Turn off the engine. When stopping the diesel forklift truck, it should idle for a few minutes. After the spare parts are cooled evenly, operate the stop handle, turn the fuel injection pump column to the position without fuel supply, and then stop.
4、Common phenomena:
1. The engine suddenly stops running
2, no abnormal symptoms before extinguishing
5. Cause and treatment of failure:
1, no oil tank: treatment method: refueling
2, diesel mixed with water or air, treatment method: remove water or air
3, the pipe is blocked or broken, treatment method: dredge or replace the pipe
4, the fuel filter is blocked, treatment method: replace
5, the tubing joint loose air intake, treatment method: squeeze the joint exhaust the air in the oil path
6, the oil pump does not supply oil, treatment method: repair or replace the oil pump
