2.14. Fuel Injection Nozzle Check the housing crack, damage etc. and replace it if abnormal. Check if the idle operation and speed regulating lever’s sealing is removed. The adjustment and testing of fuel injection pump should necessarily be done at the test bench. 2.15. Battery Inspect for any leakage of electrolytic solution owing to battery crack, and replace the bat- tery in case of poor condition. Inspect for amount of electrolytic solution, and replenish if insufficient. Measure the gravity of electrolytic solution, if less than specified value (1.12 ~ 1.28), replen- ish.

Air Removal of Fuel System The suction room of fuel injection pump has the function of air removal continuously during the operation through a relief valve. In case that the suction room lacks fuel at all, for instance, in case of new installation of injec- tion pump, after loosening the air removing screws of cartridge filter respectively, remove the air by operating the manual pump of fuel supply pump until bubble will disappear. 2.17.
Fuel Supply Pump Every time of engine oil replacement, the fuel strainer installed at the fuel supply pump should be removed and cleaned. - 32 - TECHNICAL INFORMATION Viewing the gravity mete비r 중 Liquid level indicating line 는법 계를 보 L ind 는법
