4.5 Check before Starting the Machine
Be sure to check the machine before operation.
When any abnormality is found, be sure to repair it before starting the unit.
Be sure to make daily check before operation. If the unit is operated without prior check and without
noticing its abnormality, such operation could cause seizure of components or may even cause fire.
4.5.1 Check Engine Oil Level
The machine should be on level before checking oil level.
When you check oil level after you have once started operation,
wait 10 to 20 minutes after stopping engine, before checking the
oil level.
＜ Procedures＞
① Pull out the engine oil level dipstick, and wipe it with a clean
cloth.
② Then, re-insert the dipstick fully and pull it out again. If the
gauge shows the oil level between UPPER and LOWER limits,
it is normal.
③ When the oil level is below its LOWER, add engine oil.
(See 5.5.1.)
While checking oil level, check also for contamination. If the oil
is found dirty, contaminated, or should be changed according to
the periodic inspection list, change the o
il.
4.5.2 Check Coolant Level
Be sure to stop the machine first and then loosen the radiator
cap slowly, after the coolant water is sufficiently cooled and the
inner pressure is released.
If this procedure is neglected, its inner pressure can blow off the
cap, and steam jetting out of the radiator could cause scalding.
Check the coolant level in the reserve tank. If it is lower than
the limit, open the cap and replenish the coolant.
(Level must be kept above LOW mark)
If little coolant is left in the reserve tank, replenish the tank and
radiator also. (See 5.5.15)
