Changing Engine OilNBMA0015WARNING:
IBe careful not to burn yourself, as the engine oil is hot.
IProlonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Stop engine and wait for more than 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.

CAUTION:
IBe sure to clean drain plug and install with new washer.
Oil pan drain plug:
: 29 - 39 N´m (3.0 - 4.0 kg-m, 22 - 29 ft-lb)
IThe refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.

5. Warm up engine and check area around drain plug and oil fil-
ter for oil leakage.
6. Stop engine and wait for more than 10 minutes.
7. Check oil level.
SMA097D
Changing Oil FilterNBMA00161. Remove oil filter with Tool.
WARNING:
Be careful not to burn yourself, as the engine and engine oil
are hot.
The filter is a full-flow cartridge type and is provided with a relief
valve.
