Please read the Operation Instructions carefully for safety.
1. Notes to Safety
Please read the Operation Instructions carefully and understand it thoroughly before use. Following
notes shall be observed for safety concern. In addition, it contains information on Danger, Warning and
Caution.
※Nevertheless it may contain some information not corresponding to your product. Please
understand it (if any).
1.1 Basic information
1) Please read it and understand it thoroughly
before use in order to ensure safe driving.
2) If the loader is lent to others, instruct the user
operation methods in details and to read the
Operation Instructions carefully in advance.
3) Do not make mechanical modifications willfully
because it is dangerous. Otherwise unexpected
incidents may occur and damage the safety of
loader.
4) Wear safety helmet, shoes and clothing during
driving, check and maintenance. If required by
specific jobs, wear goggles, dust-proof respirator,
sound-proof device, protective gloves, safety belt
and others. However confirm functions of
protective articles in advance. Keep the driving
seat clean around. If there is any oil, grease,
ice, snow or mud on the step or rail, driver may
fall. Additionally check if mud or any foreign
matter at the sole.
5) Please carry out pre-start check.
●Check if early operation causes such abnormal
changes as oil/water leakage, loose bolt, nut or
connection and broken wire on mechanical parts.
Resolve abnormality (if any) immediately.
●Use specific fuel and grease.
●Check pneumatic pressure, wear-out and
damage of tyres.
6) Lubricate the loader. Stop the running engine
during check and regulation. Forbid the open
flame when filling the fuel and prevent the
overflow of fuel.
7) Do not lift or drive any person with bucket of
loader.
8) Forbid persons under lifting bucket.
9) Do not touch overhead wire or obstacles when
lifting up the bucket. Touch may cause electric
shock even death.
10) Do not drive it if driver drinks alcohol, takes
some medicine or is unwell. Otherwise
unexpected incidents may happen.
1

Please read the Operation Instructions carefully for safety.
1.2 Notes to pre-start
1) Hold rails tightly to avoid the slip. Do not
jump on or down the loader. It is danger! Do
not hold operating levers when entering or
leaving the cab.
2) Adjust the seat properly. Improper seat causes
wrong operation and fatigue even unexpected
incidents.
3) Please check followings before starting the
engine.
·Check if any person is around the loader.
·Sit in the driver cab before startup.
·Check if operating levers are at the neutral
position
·Check if shovel touches the ground and stop
brake is normal.
·Check if any inflammable materials around the
engine.
4) Check working conditions of bucket, moving
arm, driving and turning after engine starts in
place free of person and block. If any
abnormality, settle and repair it.
1.3 Notes to operations
1) Sit in the cab and drive the loader correctly.
Do not gaze around, jump on or down the cab
during driving. Forbid unessential operators in
the cab.
2) Do not use it for unintended applications.
Otherwise it may not only damage the loader but
also cause unexpected incidents.
3) Check if the loader is exposed to any danger
before start. Increase the rotation speed of
engine and drive the loader slowly. Do not start
and drive the loader quickly.
4) Prohibit the entry of any person in the
operating area.
5) Fix the bucket tightly when loader runs on the
road or a long distance. Unintentionally touching
the operating lever will change the pose of
running loader, leading to incidents. The correct
pose of running loader is to keep bucket about
40m above the ground.
6) Abnormal drive such as quick start, brake,
rotation, driving in the zigzag form and high speed
will contribute to the turnover of loader and cause
serious injury even death. In particular, quick
rotation of loader at high speed can cause the
turnover to side. It is extremely dangerous.
7) Lower the bucket as much as possible when
loader delivers the sand to keep the center of
gravity at a low level. Loader cannot keep the
balance if bucket of running loader is raised
beyond the upper limit. Loader is exposed to
the danger due to higher center of gravity.
8) Uneven operating area may contribute to one
factor of turnover incident. Therefore select the
flat operation ground for driving. If there is any
stone or obstacles on the route, do not pass it by
inclining loader or at high speed. Such incorrect
operation may lead to turnover. The correct way
is to reduce the speed and run across an obstacle
when stability of loader is ensured. Check the
capacity of load of bridge or structure before
loader drives on it. If capacity of load is
insufficient, strengthen it.
9) Avoid any operation along a slope as much as
possible. Loader will lose balance and be
exposed to danger if excavating the inclined
section.
2

Please read the Operation Instructions carefully for safety.
10) According to Rule for Labor Safety and
Health, machine must be provided with protective
cover if it is used for application that labor is
exposed to hazard such as falling stone. In such
dangerous situation, do not use machine without
protective covers.
11) To ascend an abrupt slope, select the
Backward and keep the loader stable. Drive the
loader slowly and lift the bucket about 20-40cm
above the ground. To descend a slope, select the
Forward and keep the loader stable. Drive the
loader slowly with bucket close to the ground.
12) Do not make a turn on a slope as much as
possible. Make a turn on the flat ground if
possible.
13) Drive the loader at the relatively low speed in
the confined space, room and place with stored
matters. Meanwhile pay attention to surrounding
conditions.
14) Consider the possibility of collapse when
loader moves along cliff or abrupt slope.
Strengthen it or take other appropriate measures
if necessary. It turns more dangerous after it
rained. Do not approach such places willfully and
position where stone may slide down.
15) Soft ground may catch tyres, leading to
imbalance. In such case, check the capacity of
ground before operation. If loader descends a
slope or slides to side and ground is soft, lower
the bucket immediately as brake.
16) When loader drives or brakes on the
snow-covered or frozen ground, skid or lateral
slippage may occur. Do not carry out quick
brake, start, rotation and other dangerous
actions. Front wheels are typically furnished with
anti-skid chains. In case of jobs under snowy
conditions or requiring traction, both front and
rear wheels must be fitted with anti-skid chains.
17) When speeding down a slope, do not brake
wildly.
If pressing down the “low-speed securing” button,
speed descends and shifts rapidly when loader
drives at the high speed. Then rear section of
loader may be lifted a little and float. Sometimes
it causes danger. Reduce the rotation speed of
engine and shift slowly.
(1) Stop the engine when descending a long
slope. In such case, trigger the “low-speed
securing” button and brake of engine at the same
time.
(2) Operate the brake pedal for over-speed.18)
Do not operate the Stop Brake when loader is
running. Sudden stop is extremely dangerous.
19) It is very likely to happen that loader slides to
side or loses the balance in case of inclined
connection. It poses a great danger.
20) The steering wheel of loader is different from
that in car. It cannot return to original position
automatically after it is operated for turning.
Thus reset the steering wheel manually
21) If any tyre bursts, operate the loader as
emergency stop or lower the speed mildly but not
work the steering wheel in a hurry.
22) Goods may fall down to one side of cab if
loader operates unstable goods or jobs at a
relatively high level. Therefore do not lift bucket
too high or lean back when loader operates
unstable goods.
23) Turnover is very likely to happen due to
counterforce in case of abrupt descending or
emergency stop, particularly it is loaded.
24) Know positions of cable, gas pipe, running
water pipe, sewer and other underground
facilities before excavation.
25) Excavation under cliff is exposed to collapse,
falling stone and other possible great risks.
26) Indoor job may generate the waste gas and
cause toxic conditions. Ensure sufficient
ventilation for indoor jobs (in the shelter). Check
the loader outside in advance.
3

Please read the Operation Instructions carefully for safety.
1.4 Notes to post-operation
1) Park the loader on the flat ground. If loader
has to be parked on a slope, bucket shall fall
down to the ground. And place stop blocks
around wheels.
2) If driver leaves the cab,
·Bucket falls to the ground.
·Stop the engine and move operating lever to
release the pressure.
·Place operating lever of forward and backward
at the neutral position and lock the operating
lever of bucket at the neutral position.
·Take away the triggering key.
3) Before storage, cool the silencer and other hot
parts then close the protective hood. Otherwise
it may cause fire accident.
1.5 Notes to maintenance and service
1) Check and clean the loader and operating
parts. Stop the engine before each check,
adjustment and leave. It is dangerous to check
the running loader. Carry out any check at safe,
solid and flat ground.
2) During check and maintenance, identify the
serviced part with Label “In check and
maintenance” in order to avoid unessential
person from touching or operating the loader.
Place some warning marks around the loader.
3) Do not use materials that easily ignite fuel or
battery during mechanical maintenance and fuel
supply.
4) Ensure sufficient ventilation if maintenance is
done indoor or at place with poor ventilation
conditions. Local ventilation is a must when
exposure to waste gas, fuel, cleaning oil and
paint.
5) Use the approved service kits. Unapproved
service kits will not only reduce the working
efficiency but also cause injury.
6) Support and fix the engine hood and other
components before maintenance and check
around the engine.
7) Place the start button at Off position when
welding the loader. Do not place hazardous
materials between welding and earthing parts
because welding may generate heat and cause
the electrical spark. Otherwise energized cylinder,
sealing bearing and other devices may pose
danger.
8) Water in the electrical system can cause the
short circuit or abnormality. Keep battery,
sensor, connection and other electrical parts
away from water.
9) Wear goggles and position the oil leakage with
heavy board if leakage is found in a invisible small
aperture. If oil touches the skin, it may irritate skin
seriously. Seek for physicians immediately.
10) Cool the engine completely before check,
addition or change of cooling water in the radiator.
Silencer is hot just after engine stops. Touch can
cause the injury!
11) Lock the operating lever before check and
maintenance on the lifting bucket. Use the
support of lifting arm to prevent them from
descending.
12) Do not lift the loader with bucket before
service and maintenance. Do not allow persons
under lifted loader. If some persons have to
work under the lifted loader, place the safety mat
and support in advance to avoid unexpected
falling. And lock the operating lever.
13) Do not use any tyre with serious damage.
Otherwise it may burst.
14) Consult the distributor of tyre, inner tube and
wheel rim for replacement and repair.
(Replacement and repair shall be done by
specially trained expert if possible.)
4

Please read the Operation Instructions carefully for safety.
15) Gas in the battery may cause fire and/or
explosion.
·Do not produce the spark near the battery or
keep the battery away from open flame.
·Do not check the battery by shorting two poles.
Use the voltmeter or specific gravity meter for
check.
·Do not charge the frozen battery. Otherwise it
may cause battery explosion. In such
circumstance, heat the frozen battery above
15 in℃advance.
·When indicator turns red, please replace the
battery.
·Battery acid (thin H2SO4) can cause blindness
or heat injury. Rinse skin or clothes with clean
water if touching the battery acid. If touching
the eye, wash eyes then seek for physician.
16) After the loader is started, all mechanical
components, operating oil and lubricant are
exposed to high temperature and pressure. Hot
operating oil may cause scald. In addition oil
spraying under pressure can penetrate the skin
and cause serious injury. Ejected plugs and
screws under pressure may also hurt persons.
Therefore disassemble components in the
hydraulic system after temperature fall down and
pressure is released completely. Do not face
any plug and/or screw to be loosened directly.
Do not stay near fuel and/or oil leakage because
pressure is high. Touching oil and/ or fuel leakage
is dangerous.
