Operation in cold/hot weather

Operation in cold weather
Cold weather can cause special problems, so special attention should be paid to protection
to prevent serious damage to the machine. Maintenance in cold weather will extend the
service life of the machine.
1) Electrical system: Keep the battery clean and fully charged. Check the battery cables and
connectors, clean the connectors, and apply a layer of grease to prevent corrosion.
2) Lubricant: Apply each joint with lubricating oil of the appropriate viscosity. Please use the
recommended oils.
3) Fuel system: Is the fuel supply suitable for the cold weather at that time. Change to low
viscosity fuel.
Check the water in the fuel system. Cold weather can concentrate water in the fuel tank.
Check the water in the fuel filter every 50 hours of operation. If there is no water present, the
inspection cycle can be extended. Check the fuel tank for any water present.
4) Cooling system: Before operating the machine in cold weather, check the coolant to
adjust the appropriate mixing ratio. Use antifreeze suitable for the ambient temperature
conditions.
5) Working device: Before operating the machine, shift to low gear and slowly start the
machine, then stop the machine and operate the attachment for about 10 minutes, or until all
hydraulic cylinders are considered to be working properly before starting the operation.
2. Operation in hot weather
In order to prevent damage to the machine, please do as follows:
1) Ensure that the amount of coolant in the radiator is normal.
2) Check the radiator before the start of the hot season and replace the coolant if necessary.
3) Remove all dirt and scale from the radiator and engine surfaces.
4) Check the fan rotation belt.
5) Use lubricating oil of appropriate viscosity.
6) Use a suitable proportion of coolant in the cooling system.
7) It is necessary to regularly check the air filter for working in extremely poor conditions
such as high dust.
