Important
* Permanent antifreeze or long term preserved
refrigerant is preferred.
* letting out the cooling water, cleaning the
watermark, add the mixed fluid of water and
antifreeze.
* No need to add antirust for the antifreeze
contains antirust.
* For the antifreeze is of incendivity, watch out the
fire. If contacting skin, do wash with clean
water.
4.6 Precautions after operation in low temperature
Clear the clay and water adhering to the
machine. Keep the machine on the concrete
ground or dry ground, especially the clay
around the wheel, which may incur abnormal
driving due to freezing. If there is no proper
place to park the machine, place board or
straw mat and park on it. If parking the
machine directly on the earth, the wheel shall
freeze on the earth in the next morning then
the machine can not be driven normally.
Especially, wipe clear the drops on the surface
of piston bar of hydraulic cylinder. If the drop
and clay is taken into the cylinder, it may
damage the airproof circle sometimes.
Discharge the stored moister in the fuel system
by drainpipe to avoid freezing of moister stored
in the night.
4.7 Check after starting
1. After starting, take a 5 minutes warming
machine running.
The performance of the engine and hydraulic
oil can not be fully played when they are
cooled. Do take the warm machine running
before running the machine. Before the end of
warm machine running, try to avoid urgently
accelerated running of engine.
2. After the motor is warmed, do confirm the
following items:
◎
Whether the engine oil lamp is off.
◎
Whether the battery charger lamp is off when
increase the engine revolution.
◎
Whether the exhaust is normal in color,
whether there is abnormal sound or vibration.
◎
Whether the pressure lamp of the hydraulic oil
is off.
Any leak of oil, fuel or water.
◆
stop the motor directly if any of the
following occurs:
1. Sharp drop or rise of the motor revolution.
2. Abnormal sound
3. Abnormal exhaust color.
4. The machine oil alarming lamp is on during the
running of the motor.
5. The hydraulic oil lamp is on during the running
of the motor.
Important
* Having any doubt during inspection and
maintenance, please contact the appointed
service company and follow its instruction.

Precaution of overheat
Operate as following when the cooling water is
close to boiling point or above
（
so-called
overheat
）
:
1. Stop it in safe location.
（
clear the load of the motor
）
2. Do not stop the motor urgently but keep it
rotating at medium speed. After cooling slowly,
stop the motor.
3. Wait for 10 minutes or keep away from the
machine when the steam is bursting out.
4. After the motor is fully cooled, solve
overheating according to the [reasons and
solutions of failure] and then restart the motor.
4.8 Stop motor
Keep the motor racing for 5 minutes or so. After
cooling slowly and operate as following:
1. Move the bucket operation handle slowly and
put the bucket on the ground.
2. Return the start key to [off] and make the motor
stop running. Then pull out the key.
Important
* Stop the motor urgently before it is cooled may
decrease the service life of each part, thus
urgent stop is not allowed except urgent
situation.
* The gun handle is of high speed so sometime
the motor cannot be stopped. Please make the
gun handle in low speed.
Important
* Stop the motor urgently before it is cooled may
decrease the service life of each part, thus
urgent stop is not allowed except urgent
situation.
*Do not stop the engine immediately if it is
over-heated. Run at medium speed and stop the
engine after cooling it slowly.
* Keep the forward and backwards handle bar on
[EMPTY] when stopping, leaving or repairing
machine and take the stopping brake. Keep the
shovel contacting the ground, and keep the
shovel handle bar on [EMPTY]; stop the
