Maintenance methods
Figure12 check and replace the oil
Always check the oil level in the oil sump:
There is an oil gauge at the left side of the
cylinder block (look from the side of
flywheel). Before checking the oil level,
bring out the oil gauge and wipe it dry.
Then, put the gauge in and bring it out
again to check the oil level. The level should
be within the upper and lower limits of the
oil gauge (as shown in Figure 12). If the
level is not enough, add some oil, as
required, from the cylinder head cover.
Total oil volume in the oil tank is about 13L,
and the oil volume in the oil sump is about 11L. At the bottom of the oil sump, there is
an oil passage screw plug, which can be used when we need to replace the oil. Replacing
oil should be done just after stopping engine. At this time, foreign matters and oil are
mixed and can be replaced together. Waste lubricating oil should be collected after being
replaced in order to prevent polluting environment.

De-aerate the fuel in the fuel pipe
Figure 13 De-aerate the fuel in the fuel pipe
Outside the fuel injection pump, there is a fuel
supply pump, which is equipped with a hand
priming pump. The hand priming pump can be
used to de-aerate the fuel in the fuel pipe. When
using the hand priming pump, revolve the
handle cap and it will rise up. Push the cap down
again and again, the fuel can be pumped from the fuel tank to each fuel passage and the
fuel chamber. At the same time, loosen the air outlet screw plug and expel the air out.
After using the hand priming pump, revolve back the handle cap in case that the air go
into the fuel supply system.
