1. Oil level check and refilling
The fuel level shall be checked through the
fuel gauge on the side of the fuel tank or
the fuel level indicator on the combined
instrument on the front right of the cab.
Check once every day or every 10 hours.
To avoid the formation of condensate, the
tank should be filled up after daily work.
The fuel filler port is located in front of the
fuel-hydraulic tank.
2. Drain water and impurities from the
tank
Condensate and sediment are discharged
every 100 hours.
Loosen the oil valve to allow the
condensate and sediment to flow out. Once
fuel flows out, reinstall the drain plug.
Based on the quality of the fuel used, users
can redefine the cycle for discharging
condensate water themselves;
3. Clean the fuel tank
Clean once every 250 hours.
1) Prepare a container to receive the discharged fuel
2) Remove the oil drain valve and take out the filter screen located in the oil filler port. Fill half
of the fuel tank and empty again.
3) Clean the refueling filter and install it in place.
4) Reinstall the fuel drain plug and fill up the fuel through the filter in the fuel hole.
4) Exhaust the air in the oil circuit.
Attention: Only diesel instead of trichloroethylene should be used for flushing the
interior of the fuel tank.
