dipstick with a clean rag. Insert the dipstick
completely and remove it to check the oil
level. If the engine oil level is low, add the
specied engine oil from the engine oil
ller (B) until the engine oil level is in the
operating range on the dipstick.

tools. Release the two latch hooks on the air
cleaner canister cover and remove the cover.

lter by tapping the lter against another
object. Apply compressed air from inside of
the element to blow away the dust. Clean
every 100 hours or if necessary, replace
every 1 year or if necessary.

for safety. Using the thumb, gently apply
pressure to the midpoint (A) of the alternator/
fan belt between the pulleys. Check whether
the alternator/fan belt deects inward by

a pre-diluted coolant with an antifreeze to water
ratio that suits the local climate*.
