8-4 Checking/every 200 hours
Checking/every 100 hours is also required.
(1) Replacement of engine oil filter cartridge.
Refer to「8-2.(2) Replacement of engine oil filter cartridge See p.39」.
8-5 Checking/every 400 hours
Checking/every 100 and 200 hours is also required.
(1) Check on battery gravity.
Measure the battery gravity if there is a suspicion that battery
leakage has occurred especially where there have been instances
where the machine would not start.
The relationship between Battery Gravity and Battery Charging at
20 ℃.
Battery Gravity Battery Charging
Over 1.28 Over charged(need adjustment)
1.25 － 1.28
Optimal charging
1.24 － 1.25
Average
Below 1.24 Low charged(need adjustment)
In determining the specific gravity at a temperature other
than
20 ℃, use the following formula:
Ｓ
20
= St ＋ ０．０００７(ｔ－２０)
where Ｓ
20
: is the calculated specific gravity at 20 ℃.
St : is the measured specific gravity
ｔ : is the battery solution temperature reading.
(2) Replacement of fuel filter element.
① Turn the fuel filter cock to the close position. Remove
the ring screw and take out the filter cup and element.
② After replacement, fit the fuel filter back to its original position.
Make sure when the fuel filter is being refitted that it is not
overly dusty.
