firmly and reliably, individual control mechanisms work normally, individual pipe connections are tightened
firmly, or oil leakage, water leakage or air leakage takes place.
●
Inspect lubricating oil level of engine oil pan, tractor transmission, rear axle and hydraulic system. Replenish
sufficient cooling water in the water tank radiator. Enough fuel should be filled in the fuel tank.
●
Pull the fuel circuit switch handle of the fuel tank to flow direction of the fuel pipe, so that the fuel circuit is
connected.
●
Inspect the transmission control lever and PTO shaft control handle, and set the main shift lever, PTO control
handle, front drive axle control handle to neutral position, and the distributor control handle to neutral position.
●
Pull up the shutdown cable locking device so that the shutdown cable withdraws and the fuel pump can supply
fuel.
●
Set the hand throttle to semi-opening state.
●
For the tractor that is new, overhauled or is not used for a long time, remove air trapped in oil circuit prior to
startup, so as to ensure smooth startup of the diesel engine. The method is as follows: First loosen the vent
screw of the diesel filter, and use a hand pump to pump fuel to remove the air trapped in the pipe section from
the fuel tank to the diesel filter, until no air bubbles exist in the drained fuel. Then, tighten the vent screw of
the diesel filter, loosen the vent screw on the fuel injection pump, and remove the air by the same method until
no bubbles exist in the drained fuel.
Important:
Foreign bodies should be removed regularly from the water tank screen, so as to avoid fault due to
improper heat radiation of the engine.
●
Important:
After the tractor is installed with a backsack harvester, due to bad radiation conditions during the field
working, it is recommended that an auxiliary radiation device is installed at appropriate position on the
tractor to ensure long-time continuous working of the engine.
