z Level the bucket and other work equipment to the
ground.
z Stop the machine on the level ground where there is
no danger of stone falling, coasting or flooding. If it
is necessary to stop the machine on a slope, wedge
the wheels to prevent movement.
3.4.2 Steps to Stop Engine
z Let the engine run freely for 5 minutes to cool all the parts equally.
z Pull the flameout control soft knob (if assembled).
z Turn the key to OFF position. And draw it out and keep in a safe place.

!
WARNING
Never pull the flameout control soft knob to stop the engine
before the engine is cooled.
3.4.3 Leaving Machine
z Use the ladder and handle to climb down facing the machine. Never jump down.
z Check whether there are particle-likes materials on the engine. If so, clean them immediately to
prevent fire.
z Clean all the flammable materials around the machine to prevent fire.
z Lock the door and window, and draw the key.
3.4.4 Do the Followings after Work Everyday
z Check the fuel reserves.
z Check the oil level of the engine oil pan and its cleanness. If the oil level is too high or diluted,
find the reasons and solve them.
z Check the oil pipes, water pipe, gas pipe and other parts for leaking conditions.
z Check the gearbox, torque converter, steering unit, fixing of front and rear frame, and sealing
conditions. And check whether there are overheating conditions.
z Check whether the rim bolts, transmission axis bolts and other pins are loose.
z Check whether the work equipment is in good working order.
z Check whether the wheel pressure and outside surface are normal.
z Add liquid oil to the adding points of work equipment.

z Check the quantity of the brake oil by opening the oil bowl cover of the brake booster pump.
z Drain the water in the air tank from the water outlet valve.
z Clean the outside surface of machine and the inside of the bucket.
3.5 Operations
3.5.1 Prepare to Work
Clean the working area, and fill-up any hollow spaces. Clear away the sharp stones and roadblocks
that may break the wheels and operation.
3.5.2 Modes of Work
(1) Loading Operation
z Work together with a truck which can help improve working efficiency especially for long
distance transportation.
z When working together, the loader digs the material and
the truck transports and unloads the material:
There are generally two loading and unloading ways:
z Cross Load:
The loader faces the material, then it moves backward
after digging a full load and lets the auto-unload truck
move into the position between material and the loader. This method costs the minimum time and
can reduce the cycle time most effectively.
z “V” Shape Load:
The auto-unload truck is fixed and forms almost a
60°angle with the backward direction of the loader.
After digging, the loader moves backward and turns
the designated degree and moves forward to the truck.
The smaller the loader work angle is, the more efficient
the work is.
(2) Digging Operation
Digging Piled Soil or Blasted Rock
When digging piled soil or blasted rock, the loader should face
the material and do as follows:
z If the bucket must be lowered while driving the machine
forward, stop the machine when the bucket is about 30cm
above from the ground, and then lower it slowly.

If the bucket hits the ground, the front tires will leave the
ground and the tires will slip.
z The operator must slow the speed immediately when the
machine reaches the material pile. Simultaneously step on
the accelerator pedal, and enter the material pile with the
bucket.
z Keep the bucket horizontal when loading the stockpile, but
keep the dumping angle down when loading the blasted rock.
Notice:
Do not let the blasted rock go under the bucket which will make
the front tires leave from the ground and slip. Try to hold the
load in the center of the bucket; otherwise, if the load is on one
side of the bucket, it will be unbalanced.
z Raise the lift arm to prevent the bucket from inserting too
deeply while thrusting the bucket into the material. The tires
will bring ample traction by raising the lift arm.
z If enough material is loaded into the bucket, operate the
working equipment control lever to take back the bucket in
order to load it fully.
Remark:
If the shovel edge moves up and down when thrusting material into
the bucket or when digging, the front tires will leave the ground
and slip.
z If there is too much material loaded into the bucket, the bucket
must be dumped and titled quickly to remove the excessive load so as to prevent the material from
dispersing during transportation.
Digging and Shoveling Material on Flat Ground
Lightly set the bucket edge leaning on the ground (see picture)
when digging and shoveling material on flat ground. Be
careful not to fasten the load to one side which will cause
unbalance. This operation should be carried out carefully in
gear .

z Lightly set the bucket edge facing down.
z When driving the machine forward, operate the working
equipment control lever to let the lift arm lower down to the
proper position so that it can pick up a thin layer of the surface
each time when excavating the soil.
z When driving the machine forward, shift the working equipment control lever backward and
forward slightly to reduce the resistance.
△
!
NOTICE
Keep the two sides of the bucket cutting into the material equally
to prevent only a single side working. Face the loader forward and
never let an angle exist between the front and rear frame.
(3) Conveying Operation
The loader must be used without a truck under the following conditions:
z The ground is too soft and not level, and the truck can not be used.
z When the transportation distance is within 500 meters, it is not economical to use a truck.
z The transportation driving speed is determined by the road condition.
z In order to get good visibility and stability, the bucket should be turned to its upper limit
location(bucket lift-arm touch the upper limited block) and keep the lower pin connection point
of lift-arm at the transportation position (400~500mm above the ground).
(4) Dumping Operation
z When dumping material on to trucks or into freight
yards, raise the lift-arm to the position (forward tilt to
the maximum position) where the bucket does not touch
the carriage or material pole. And operate working
equipment control lever to tilt the bucket forward to
dump. Part or all of the material can be dumped by the lever control. Act slowly and gently
during dumping to prevent the bucket from striking the ground.
z If the material sticks onto the bucket, move the working equipment control lever cyclically to
allow the bucket to tilt forward or backward to shake down the material.
