Foreword
It is particularly important that the operator should read these instructions carefully in order
to operate and maintain the excavator safely and correctly. Otherwise accidents or damage may
occur.
The manual supplies safety rules and labels which have been fixed on the machine so as to
provide the instructions of potential danger and the ways to avoid it.
SUNWARD cannot predict any kind of potential danger may occur in the process of
operation and maintenance. Therefore, the related instructions in this manual and on the machine
only concern the basic safety rules. It is the operator’s duty to take necessary measures to protect
safety if there is no corresponding method recommended in this manual.
The forbidden usages or operations that mentioned in this manual can not be engaged in any circumstances.
The excavator is designed according to the metric system, all the data presented are metric and only metric

1.1.2 Safety labels instruction
（1）Precaution for operation
Please carefully read all safety precautions
written in labels and all information
concerning safety, prior to operate machine.
Maintenance frequently and replace safety
label if required. In case that safety labels or
manual are damaged or lost, you can place an
order with our distributors. The procedure of
ordering them is identical with that of the other
parts and components. You must specify model
of the machine when ordering.
Use only trained and qualified personnel to
operate this machine. Follow all safety
precautions and instructions in this manual to
keep your machine in good condition.
Do not alter or modify machine rashly, this
may impair function and effect service life or
jeopardize personal safety.
Caution: all safety information described in
this manual covers only basic safety
information of this machine. It’s not possible to
predict every circumstance which might
involves potential hazards. So it’s necessary to
ask for instruction from your superior before
attempting any operation or maintenance
procedure.

（2）Precaution for operating engine
Diesel engine inspection
Stop machine on level ground, inspect engine
oil level (stop engine for longer than 15
minutes to allow engine oil to go back to the
bottom), inspect dipstick to make sure oil level
must be between the lines of “MIN” and
“MAX”. For engine maintenance procedures,
please refer to the “diesel engine maintenance
manual” enclosed with the other literature of
the machine.
Pre-start inspection
Keep control lever of pilot valve in LOCK
position, pilot handle and travel pull link are in
normal position (neutral position), operator sit
over seat.
While switching the key to ON position,
except engine hour meter and LCD module, all
indicators of test system must light up. Buzzer
must sound as well. Self-test is finished in 2
seconds to indicate test system is or is not
properly functioning.
Start the engine
Keep control lever of pilot valve at LOCK
position.
Switch key to ON position.
Sound horn to alert the persons around.
Turn the key to the right; hold it in START
position until engine runs. Then release the key,
switch will automatically. Return to ON
position.
Caution
Do not operate motor for longer than
5 seconds ever time to avoid damage
to machine. In case of failure to
start engine, switch the key back to
OFF position, wait 2 minutes before
a new attempt. Incorrect start may
damage to starter.

（3）Diesel label
Caution
Refilling fuel with extra care. Stop
engine before refilling fuel. Do not
smoke while refilling to fuel tank or
operating around fuel system.
Select proper fuel according to
different ambient temperature.
Refer to “stop engine” section for properly
parking machine and stopping engine.
Inspect fuel gauge on monitor, top up is
required.
Prevent dirt, dust, water and other foreign
matter from entry into oil tank and fuel system.
While refilling at the end of daily work-shift,
do not spill, drip any fuel to machine or ground
to avoid fuel clotting.
After refilling fuel, fasten cap securely.

（4）Machine posture symbol
Caution
Do not start engine when hydraulic
oil tank runs out of oil.
Inspect hydraulic oil level……daily
Park machine on level ground.
Completely retract arm cylinder and extend
bucket cylinder to full length.
Lower bucket down to the ground.
Run engine at low speed for 5 minutes.
Shut down engine, remove the key.
Place pilot control lever to LOCK (up)
position.
Open right side door to check oil level gauge.
Located on hydraulic oil tank, oil level must be
within level marks. Pump oil if level is higher
than MAX mark, refill if level is below MIN
mark.
add oil：
Remove upper breather screw cap by rotating
anticlockwise.
Refill oil through strainer. Recheck oil level
gauge.
Fasten cap securely.

（5）Service and lubrication symbol.
Proper procedure of maintenance and
inspection
Learn about how to properly service machine.
Perform proper maintenance and inspection
procedure in accordance with this manual. Inspect
machine before starting machine.
Check monitor.
Check individual liquate level.
Check hose and piping for leakage, twist, wear
out or damage.
Check surrounding the machine for any signs
of noise, heat etc.
Check parts for looseness and lost.
Caution
If any problems are detected, repair
prior to operation, or contact our
authorized distributor.
Use recommended fuel, hydraulic oil and
lubricant.
Use only genuine SUNWARD components.
The warranty is not applicable for any
damages arising from failure to use
SUNWARD recommended fuel, lubricant,
hydraulic oil and genuine SUNWARD
components.
Do not adjust speed limiting governor of
engine or safety valve of hydraulic system.

（6）Wiper label
Properly use wiper.
（7）Filter core safety label
Replace pilot oil filter every 400 hours
Stop machine on a firm and level ground.
Lower bucket to the ground.
Run engine at low-speed for 5 minutes.
Shut down engine, remove the key.
Relieve internal pressure which builds up in
hydraulic system by means of left/right pilot
joystick.
Set pilot control lever in LOCK (UP) position.
Use wrench for filter to remove filter housing
off the filter head cover by rotating
counterclockwise.
Remove filter core and used 0-ring.
Clean the area in contact by head cover and
o-ring.
Apply a new layer of fresh hydraulic oil, and
place it in position.
Lubricate new filter core with a thin layer of
clean hydraulic oil on the ring section. Push
filter core upward while moving it forward and
backward alternately to install it.
