Engine oil and oil filter element
The engine oil level should be checked before
each ride. In addition, the oil must be changed
and the oil filter element replaced at the inter-
vals specified in the periodic maintenance
and lubrication chart.
To check the engine oil level
1. Place the ATV on a level surface.
2. Start the engine, warm it up until the en-
gine oil has reached a normal tempera-
ture of 40 °C (104 °F), let it continue to
idle for ten seconds or more, and then
turn the engine off.
NOTE:
_
To achieve the proper engine oil temperature
for an accurate oil level reading, the engine
must have first completely cooled down, and
then warmed up again for several minutes to
normal operating temperature.
_
3. Remove the engine oil tank filler cap,
wipe the dipstick clean with a clean rag,
insert it back into the filler hole (without
screwing it in), and then remove it again
to check the oil level.
