2.2.2 inspection after initial 50 hours or one month operation
Be sure to check the following points after initial 50 hours or one month operation, whichever comes first.
(1) Drain the fuel tank
1) Put a pan under the drain cock to catch the fuel.
2) Open the drain cock and drain off any water or dirt
collected.
3) When the water and dirt are drained off and the
fuel comes out, close the drain cock.
(2) Replace the engine lube oil and the lube oil
filter.
During the operation of an engine, the oil is quickly
contaminated due to the initial wear of internal parts.
The lube oil must therefore be replaced early. It is
easiest and most effective to drain the engine lube oil
after operation while the engine is still warm.
Replace the lube oil filter at the same time.
Beware of oil splashes if extracting the Lube oil while it is hot
1) Remove the lube oil dipstick and also the oil filler cap at the top of the rocker arm cover. Attach the
oil drain pump to the dipstick guide and drain off the lube oil.
[Notice]
For easier draining, remove the oil filler cap (yellow) at the top of the rocker arm cover.
When lube oil is absorbed without removing a oil filler cap, negative pressure grows big in the
crankcase and it may cause the rubber of the diaphragm cracked.
2) Turn the lube oil filter counter-clockwise using a
filter wrench to remove it.
