(1) Replace engine oil filter cartridge.
Refer to ^8-2.(2) Replacement of engine oil filter cartridge Seep.39J .
8-5 Check/every 400 hours
Check/every 100 and 200 hours is also required.
(1) Check 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.

In determining the specific gravity at a temperature other than
20 °C, use the following formula:
S 20 = St + О. О О 0 7 ( t ~ 2 O)
where S 2o : is the calculated specific gravity at 20
°C.
St
: is the measured specific gravity
t
: is the batteiy solution temperature reading.
(2) Replace fuel filter element.
© Turn the fuel filter cock to the close position. Remove
the ring screw and take out the filter cup and element.
Ф
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.
