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) Engine Operation Label
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
joystick 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.
Honk the 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 Label
Caution
Do not start engine when hydraulic oil tank
runs out of oil.
Inspect hydraulic oil level……every day
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
Caution
Posture for Checking Hydraulic Oil Level
Caution

on hydraulic oil tank, oil level must be within level
marks. Drain oil if level is higher than MAX mark,
refill if level is below MIN mark.
Fill oil：
Remove upper breather screw cap by rotating
anticlockwise.
Refill oil through strainer. Recheck oil level gauge.
Fasten cap securely.
(5) Maintenance and Lubrication Label
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 each liquid 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,
