3 OPERATION AND USE OF LOADER
3.1 Notices for Usage
z The diesel must be cleaned and deposited more than 72 hours before it is to be used. The
trademark should suit the rules.
z Transmission oil for the gearbox, torque converter, and the hydraulic oil for hydraulic system
must be clean.
z The loader must be maintained and lubricated periodically.
z Drive the loader until the brake pressure reaches 0.4MPa after the engine starts.
z Put some hot water or vapor in front of the engine for preheating it. Preheat the engine until
30℃~40℃ before starting if the environmental temperature is lower than -5 .℃
z There is no need to stop the machine or step on the brake pedal in changing the forward levers
during driving. When changing the speed from low to high, release the accelerator a little and
operate the Gear Control Lever at the same time, and step on the accelerator; when changing the
speed from high to low; release the accelerator first and then change the transmission slowly.
z After the lift-arm and bucket are moving to the required position, release the control valve lever
to the middle position.
z Change the forward or backward driving direction after stopping the loader.
z Full load work is allowed until the water temperature of the engine is above 60 and the mobile ℃
temperature of the engine is above 50 . But the water temperature of ℃ the engine should not be
over 95 and the mobile temperature of ℃ the engine should not be over 120 , otherwise stop the ℃
loader to cool it.
z Never lift the bucket to the highest position to transport material. The lower hinge of the lift arm
should be 400mm～500mm above the ground to ensure stable driving during the transporting
process.
z A diesel engine is used in the machine. The power of the diesel engine will go down as the
altitude, environmental temperature and relative temperature goes up. So please pay attention to
the environmental conditions and calculate the real power under the current environmental
condition according to the power correcting table in
