Changing the Oil

Remove drain plug

Using a 10 mm hex wrench, unscrew the oil drain plug, which 

is located on the crankcase underneath the oil filler/dipstick 

cap. 

Allow all the oil to drain from the engine.

1.

Drain oil

Drain oil into an approved oil disposal container. Contact 

your local auto parts store for information on oil disposal.

2.

Replace drain plug

Replace the oil drain plug and tighten with a 10 mm hex 

wrench.

CAUTION

: Worn out or dirty oil does not cool the

engine damage.

 

In addition to regular oil changes, it is necessary to drain the 

oil from the crankcase if it has become contaminated with 
water or dirt.
