The following maintenance tips are suitable for Shangchai diesel engine.
Check the
periphery of the engine each time before starting:
Check if the
engine is in clean state and free from useless things on it.
Check the
joints and connections of the fuel system, cooling system and lubricating
system for leakage.
Check if the
fan and its safety guard are fastened in place.
Check the
fastening condition of the accessories.
Check the
electrical circuits and the wire for intact.
Check the drive
belt for intact.
5.3.2
Checking fuel tank
Check the
fuel level in the fuel tank daily
5.3.3
Checking air filter service indicator
If the
viewing window shows the red piston, it represents that the intake resistance
of the air filter exceeds the specified value, and the filter element requires
to be replaced. Refer to Section 5.3.23 for the requirement and procedure of
the replacement. Press the button on the top of the service indicator for reset
after the replacement.
Caution: Be
sure that both end faces of the air filter are reliably sealed without leakage
after the air filter element has been changed.
Caution: Do
not start the engine without an air filter, and failure to do so would easily
cause early engine wear.
5.3.4
Checking oil level
Check the
oil level daily before starting the engine for the first time, and the oil
level should be near the mark 3 (static high oil level). Or check the oil level
daily at idle or low speed when the engine is in operation, and the oil level
should be between the mark 2 (dynamic high oil level) and the mark l (dynamic
low oil level). if oil is not enough, supplement it to near the mark 2 and if
the oil level is below the mark l, add oil immediately to near the mark 2.
Caution: Do
not run the engine when the oil level is below the mark l, otherwise it can
result in poor engine performance, or even damage to the engine. But the oil level
should not exceed the mark 2.
5.3.5
Checking coolant level
Check the
coolant level daily before starting the engine or after the engine has stopped.
Warning: At
operating temperature, engine coolant is hot and under pressure, and the
coolant steam can cause personal injury. Do not remover the pressure cap on the
radiator until the engine stops and the coolant temperature drops to below
50'C. Slowly loosen the cap to release the cooling system pressure before
checking the coolant level or making supplement.
Warning:
Avoid skin or eye contact with coolant to prevent personal injury because the
coolant contains alkali.
(1) Slowly
loosen the pressure cap on the radiator to release pressure before starting the
engine or until the coolant temperature goes below 50'C after stopping the
engine.
(2) Remove
the pressure cap and check coolant level from the filler or inspection port.
The coolant level should remain between the marks in the radiator or expansion
tank, or meet the requirement of the equipment manufacturer.
(3) Add if
necessary. Coolant should be added near the upper mark or meet the requirement
of the equipment manufacturer.
Caution:
Coolant should be added slowly to avoid air block.
5.3.6
Checking electrolyte level
Batteries
that are not maintenance-free need electrolyte level checking.
1）Check the electrolyte level before starting
the engine.
Remove the
filter cap and check the electrolyte level. It should be at the bottom of the
filler part. If necessary, make supplement as per requirement.
(2) Install
the cap.
5.3.7
Checking first stage fuel filter and draining water
The first
stage fuel filter has a function of fuel and water separation. Check daily if
there is water in the water container and discharge water if any. Loosen the
water drain cock to drain the water and sediment until clean fuel outflows.
Then tighten the valve until you feel suitable. Don't over tighten it.
