k k
WARNING
• Immediately after the engine is stopped, its parts and oil are still very hot and may cause burn in-
jury. Wait for the temperature to go down, and then start the work.
• If there is remaining pressure inside the case, the oil or plug may jump out. Loosen the plug slowly
to release the pressure.
Prepare a handle for the work.
1.
Stop the machine so that the TOP mark comes on the top
while a line between TOP mark and plug (P) becomes per-
pendicular to the ground surface.
2.
Remove plug (F) by using a handle, and check the oil lev-
el.
• When the oil level is near the lower edge of plug (F)
hole
The oil level is proper.
• When the oil level is far below the lower edge of plug
(F) hole
The oil is insufficient. Add oil.
Add oil until it overflows from plug (F) hole.
3.
Install plug (F).

METHOD FOR CHECKING BATTERY ELECTROLYTE LEVEL
k k
WARNING
• Do not use the battery if the battery electrolyte level is below LOWER LEVEL line. If you do so, it will
reduce the service life of the battery. In addition, it may cause an explosion.
• Since the battery produces combustible gas, it can explode. Do not bring any open flame close.
• Battery electrolyte is dangerous object. Also, take care that it does not stick your eye or skin. If bat-
tery electrolyte sticks to your skin, wash it away with large amounts of water, then get medical at-
tention.
• Do not add the electrolyte to the battery exceeding UPPER LEVEL line. It may leak and cause dam-
age to the paint surface or corrode other parts.
• Do not use a dry wipe to clean the battery. A wet wipe will prevent fire or explosion from static elec-
tricity.
NOTICE
If there is a fear that the battery water may freeze after refilling with purified water (such as a commer-
cial battery fluid), do the replenishment before the day's work on the next day.
Perform this procedure before operating the machine.
Inspect the battery electrolyte level at least once a month.
