Replace Cooling Water; Check And Adjust Valve Clearance; Adjust Valve Clearance; Check Per 1000H Operation - Kipor KM2V80 Manual

(3) Install the fuel inlet/exhaust pipe, turn on oil tank switch, and drain out air in fuel line,
otherwise hard starting or stop running after starting will be resulted.
2.4.2 Replace cooling water: Drain out water after the cooling water is cooled down, in order to
prevent be scalded by the splashing hot water.
(1) Cooling water which contains iron rust or incrustation will deduce cooling performance, as
well as refrigerating fluid.
(2) Cooling water should be replaced at least once per year. Fill in soft water only after draining
out the cooling water.

2.4.3 Check and adjust valve clearance

Make sure that the valve is off, because only in that condition there will be valve clearance.
Notice: This single cylinder/double cylinder engine is marked from flywheel terminal to gearing
box terminal, which is different from the normal way. Upper dead point line for each cylinder is
marked on the flywheel; you can see them from the dead point view port hole on flywheel cover
（φ30）. Upper dead point line for single cylinder is marked on engine body.

(1) Adjust valve clearance

a) Make sure the 1
adjust the inlet/exhaust air clearance of the 1
b) Revolve flywheel 280° in anticlockwise direction after regulation, and adjust the
inlet/exhaust air clearance of 2
Notice: Do remember tighten the adjusting screw cap tightly after regulation, otherwise it will
loosen soon and cause engine fail to work.
2.4.4 Check and adjust fuel injector: Check and regulation of fuel injecting pressure and injecting
mist quality should be operated on the fuel injecting experiment table.
(1) If the fuel injecting pressure is incorrect, please revolve down the fuel injecting parts fasten
cap, take out adjusting gasket and replace for a new one , so that the fuel injecting pressure
can attach to the correct valve（13±0.5）MPa.
(2)If the fuel injecting pressure is correct while the quality of injecting mist is poor, please clean
the injecting hole or replace the fuel injector parts;
(3)When installing fuel injector into the cylinder cover, please use the original fuel injecting
washer to make sure the fuel injecting head extend 2.2-2.3mm. Too big mistake will affect power,
fuel consumption or exhaust smoke of diesel engine.

2.5 Check per 1000h operation

2.5.1 Check and adjust the injection advance angle (please leave it to specialist, for this task
needs special tools, knowledge and skill).
