It is possible to inspect the oil by removing the transmission plug behind
the transmission. If oil reach the lowest level of the plug, proper volume
is filled.
Replacement
1) Oil should be replaced at first 20 hours, and later at each 100
hours or every year whichever comes first. Prepare oil container and
remove the drain plug located in left side of transmission case.
Replacement guideline
First : at 20 hours
Later : at each 100 hours or 1 year whichever comes first
2) Place the drain plug in original position. Remove the transmission
plug and then put transmission oil.
Recommeneded oil : “SAE 90 “or “API GL-5“.
Oil quantity : 1.00L.
After the oil is filled, tighten the transmission plug securely to avoid the leak. Pay attention not to tighten the plug
too much. When the gasket(O ring) contact the position, turn the plug in 3/4 rotation to fix it.
ENGINE OIL
CAUTION
Excess or deficiency of engine oil will cause engine trouble. Add engine oil in case of deficiency and reduce it in
case of excess to maintain proper volume.

1) Use the oil gauge to inspect the volume and quality of engine oil
prior to every use.
2) Maintain the engine oil to be on maximum level on the indicator.
Replacement guideline
First : at 8 hours
Later : at each 100 hours or 1 year whichever comes first
In case of use in very hard or hot condition, it is recommended to replace
the engine oil earlier at 50 hours and to replace oil filter at 100 hours.
Replacement
1) Prepare oil container and loosen the oil cap. Then remove the
drain plug located in left front side of engine. Oil is drained smoothly when
oil cap is loosened.
2) When the oil is completely drained, place the drain plug and fix
it. Then remove the oil cap.
3) Put 1 liter of engine oil and run the engine for 30 seconds in low
engine rpm. Stop the engine and wait for 30 seconds, then add oil up to
FULL level.
4) After the engine oil is filled, make sure that oil cap is securely
fixed.
OIL FILTER REPLACEMENT
CAUTION
Do not use tool to fit oil filter, and fit it by hand.
Replace the oil filter one time against two replacement of engine oil, or replace oil filter every year.
After the engine oil is drained, follow the instruction below to replace the
oil filter.
1) Turn the filter A counterclockwise and remove it.
2) In order to avoid twisting, place new engine oil by finger around
the gasket(O ring) of new filter.
3) Turn the filter clockwise and screw it until the gasket touches part
B. And screw it in 3/4 rotation.
4) Put the requested amount of oil from oil cap.
5) Check the oil volume by level gauge, and securely tighten the oil
cap.
6) Run the engine for 2 minutes in low rpm, to check the leaking of
oil around the filter.
7) Stop the engine and check the oil volume again. Add oil in case
of deficiency.

HST OIL
Inpsection and filling up
CAUTION
HST oil is clean in the beginning, however, after the hours of operation dust inside the HST unit is accumulated
and oil gets dirty, causing problem for smooth work of HST unit. For the safe and comfortable use of machine,
regularly replace the HST oil. Especially in the hard condition, first replacement is recommened in less than 20
hours. Otherwise, metal powder inside the HST unit will choke the oil filter and cause trouble in driving(especially
reverse driving).
1) Check HST oil tank and level of oil. If the level is not in between
the UP and LOW, open the oil cap and add oil as needed.
2) Moisture adsorption sheet is placed inside the HST oil tank, in
order to avoid HST trouble and also to adsorp the water caused by
condensation.
Replacement
CAUTION
1) In case of HST oil replacement, wait until HST oil tank and HST unit is cooled down. They are still very hot
just after the engine is stopped, and it may lead to burn.
2) HST oil is also called as hydraulic oil, which transmits the engine rotation into to driving. It also helps to
lubrication, anti-rust effect, and cooling down. However, if oil is not properly maintained, it gives problem for
driving. Always use recommended oil for replacement and adding.
1) Prepare oil container. Loosen the HST oil tank cap, and remove
the oil plug(Hexagonal, M22) located in under the HST unit.
2) When the oil is completely drained, place the oil plug and fix it.
Then remove the HST oil tank cap.
3) Put 500ml of HST oil and also relace the moisture adsorption
sheet at same time.
4) After the HST oil is filled, make sure that HT oil tank cap is
securely fixed.
