(2) Refill engine oil to specified position.
(3) check the oil level again after fueling;if oil level is too low, fuel to specified level.
(4) Reinstall the service cap.

4.1.3 Oil tank/fuel oil filter
Cleaning:
(1) Remove the oil pipe from oil tank. Remove the fuel oil filter.
(2) Remove the clogging material in filter. Check the filter for damage. Replace if
necessary.
(3) Remove the oil tank. Clean it with detergent. After cleaning air dry completely,
then reinstall it.
(4) In quiet generating set, the cabinet must be removed.. Remove the oil tank.
Clean it with detergent. After cleaning air dry completely, then reinstall it.
(5) Reinstall the filter into oil tank. Connect oil pipe.
(6) Reinstall other parts in counter order for disassembling.
Refill the oil tank with diesel oil. Check the oil pipe for leakage.
4.1.4 Oil pipe/oil pump
(1) Check the oil pipe for deterioration, cracking, or leakage of diesel oil. If the oil
pipe has any abnormality, replace it.
(2) Check the magnet of pump for deterioration, cracking, or leakage of oil. If
there is any abnormality, replace the oil pump.
(3) Check for water accumulation or other foreign material in pump. If any,
replace pump.
(4) After assembling check all parts for leakage again.
Service: The fault phenomena is fluctuation of engine running or automatic
stopping -----fuel supply is insufficient or air presents.
Cause: Air presents in oil tank, oil pipe. Generally in new engine, or after oil-break
during running, a lot of air would be entered in engine pump or high pressure oil
pipe while fill oil.
Remedy:
(1)Stop the generating set. Check oil tank and oil pipe for oil-break;
(2)If oil-break happens, refill fuel oil.
(3)Loosen the circlip at the intake pipe of engine pump with a nipper pliers. Place
a container under the oil pump and oil pipe, discharge the air from oil pipe which
was entered in oil-break. Seeing oil flow out from oil pipe, connect the oil pipe to
the intake pipe of pump immediately and clip on.
Service: The fault phenomena is not starting or automatic stopping----------The oil
pump does not delivery oil.
Remedy:
(1)Loosen the discharging pipe at engine oil pump and high pressure oil pipe with
a open-end spanner.
(2)When starting open-shelf generating set by recoil or electric starter, pull out the
discharging pipe of oil pump. It is normal if there is oil in it. If no oil, replace the oil
pump.
(3)For quiet generating set check the 12V power supply first.
Checkout the voltage. Repeat the steps (1) and (2). Set the electric switch lock to
ON position. Checkout the 12V with a multimeter. If the 12V presents, replace oil
pump. If there is no 12V voltage, check the electric wiring and electric switch lock,
service according to the gauge panel.
