Engine Oil Maintenance
Check Engine Oil Level
1. Move the machine to flat ground, stop
the engine, and pull up the parking brake
lever.
2. After stopping the engine, wait for ten
minutes; let the engine oil completely flow
back to the engine oil pan.
3. Open the engine hood, the oil dipstick
is located on the center of the right side of
the engine, the oil filler is located on the
front upper of the engine.
4. Draw out the oil dipstick, wipe it with
clean cloth, reinsert the engine oil dipstick
to the end, draw out again and check, the
oil level should between the "L" scale and
"H" scale.
5. If the oil level is under the "L" scale,
add engine oil; if the oil level is above the
"H" scale, loosen the drain plug, drain
some oil. Attention: Too much or not
enough oil may damage the engine.
Change Engine Oil
When the specified oil change interval
occurs, replace the engine oil. Park the
machine on level ground, start the engine
and wait until the water temperature is at
60°C, then stop the engine. Pull up the
parking brake, remove the drain plug on
the bottom of the engine oil pan, drain the
oil into a container and replace oil filter.
Fasten the plug; fill the clean engine oil
until the oil level reaches the "H" scale on
the dipstick. Run the engine at idle speed,
check the oil filter and drain plug for leaks.
Stop the engine, wait for about 10 minutes,
and let the oil fully drain into the engine oil
pan. Check the engine oil level once more,
if the oil is insufficient, fill oil to the oil
dipstick "H" scale. Attention: Within 15
seconds after engine starts, the engine oil
pressure gauge should have the reading. If
there is no reading, stop the engine
immediately in order to avoid damaging
engine, check engine oil level for correct
position.
