inclination more than 15.
If the fuel gauge indicates in red range,
immediately refuel. Inclination of machine may
make the engine suck air and stop suddenly if the
fuel level is low.
2.4.3.2 MOVING ON UNUSUAL SURFACES
When moving on a slippery surface, keep low
speed and avoid abrupt stops and turns.
When moving on loose ground, do not move the
machine too close to the edge of cliffs and deep
ditches. It may cause overturn and fall down of
the machine.
When it is ineluctable to overpass an obstacle,
make sure that the obstacle will not incline the
machine more than 10, keep low speed and keep
the working equipment as low as possible to the
ground.

When you are going to park the machine on public road, please provide the signalling
device according to the local regulations.
When it is necessary to park the machine on a slope, please follow the procedures
following:
1) Position the machine with the bucket downward.
2) Lower the bucket and rotate it forward to rest it on the ground.
3) Engage parking brake.
4) Stop the engine.
5) Put wedges under the wheels.
2.4.4 PREVENTION OF ELECTRIC SHOCK
Voltage of Cables (kV) 1.0 6.6 33 66 154 275
Distance must be kept (m) 5.0 5.2 5.5 6.0 8.0 10.0
Do not travel or operate the machine near the electrical cables. On the working sites
where the machine may go close to electrical cables, follow the procedures below.
Otherwise it is possible to get an electric shock, which may cause serious injury even
death.
Before starting working near the electrical cables,
consult the power company what is the voltage
with the cables and inform the power company of
your coming work. If necessary, ask them to take
actions.
To prepare for any possible emergencies, wear
rubber shoes and gloves. Prepare all things you
need to call the power company immediately in
case of accident.
Even going close to the high-voltage cables can cause electric shock. Always maintain a
safe distance (see the table up) from the cables.
Use a signalman to give warning if the machine approached too close to the electrical
cables.
If the machine come too close to or entangled with the electrical cables, do not leave the
cabin and let any person approach the machine until the electricity has been shut off.
2.4.5 LIMITS OF THE MACHINE
This machine has been designed for one operator. More than one passenger on the
machine can be extremely dangerous. Never transport more than one passenger with this
machine.

Overload could cause serious injuries or even death. Never overload the machine. For
the detail capacity of machine, please refer the section of specification in this manual.
Do not try to get a better efficiency of the machine by doing any unauthorized change.
2.4.6 TRANSPORTATION
Particular care must be taken when loading and
unloading the machine.
Try to do the loading and unloading on a firm and
level ground or a proper platform special for
loading and unloading.
Always use ramps with adequate strength and
width. The surface of ramps must be clean.
Slippery substance on the ramp surface must be
wiped up before loading and unloading. Special treatment on the ramp surface is
necessary in rainy day. The inclination of the ramps can’t be over 15.
The transporting vehicle must be positioned by wedges under the wheels when
processing loading and unloading. Make sure the ramps are securely fixed on the
transporting vehicle.
The ramps must be parallel and never do steering when traveling on the ramps. If the
machine traveling direction is not accordant with the ramps, please get down ramps and
try again.
Always keep low speed when loading and unloading machine. Be careful that any part
more than wheels touching goods around can change your traveling trajectory.
It is advisable to keep the bucket downward on ramps when the bucket is empty. Also
the gravity center of machine will change suddenly at the joint between ramps and
transporting vehicle, travel extremely slowly on
this point to keep the balance of machine.
2.5 MAINTENANCE PREVENTION
2.5.1 GENERAL RULES
To do any maintenance position the machine on a
firm and flat surface, rest the equipments on the
