fuel filter.
6. Turn fuel filter upside down to drain fuel.
7. Remove drain plug from fuel filter.
INSTALLATION
Install in reverse order of removal, paying attention to following:
●Replace O-ring on drain plug with new one.
●Screw the fuel filter by hand until packing contacts sealing surface of bracket. Then tighten it by turning

Changing Air Cleaner Filter
ELS000CG
VISCOUS PAPER TYPE
The viscous paper type air cleaner filter does not require any clean-
ing operation between renewal.
Changing Engine OilELS000CH
WARNING:
●Be careful not to burn yourself, as the engine oil is hot.
●Prolonged and repeated contact with used engine oil may
cause skin cancer: try to avoid direct skin contact with
used engine oil. If skin contact is made, wash thoroughly
with soap or hand cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine
oil leakage from engine components.
2. Stop engine and wait for 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain engine oil.
●Install drain plug and refill with new engine oil.
Engine oil specification and viscosity:
●API grade CF-4.
●ACEA B1, B3, B4, B5
●Refer to MA-16, "RECOMMENDED FLUIDS AND LUBRI-
CANTS" .
Engine oil capacity (Approximate):
●The refill capacity depends on the engine oil temperature and drain time. Use these specifications for
reference only.
Always use the dipstick to the determine when the proper amount of engine oil is in the engine.
CAUTION:
●Be sure to clean drain plug and install with new washer.
●The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.
Always use the dipstick to the determine when the proper amount of engine oil is in the
engine.
5. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
6. Stop engine and wait for 10 minutes.
7. Check engine oil level. Refer to LU-18, "
ENGINE OIL" .

4. Remove the O-ring from the filter body.
●Push the O-ring in one direction, lift the slack part using fin-
gers, and remove the O-ring from the filter body.
CAUTION:
Do not use wires or flat-bladed screwdrivers etc. as they
may cause damage to the filter body.
INSTALLATION
1. Completely remove all foreign objects adhering to the inside of the filter body or O-ring mounting area
(body side and bracket side).
2. Install the oil filter and O-ring to the filter body.
●Push the oil filter into the filter body completely.
3. Install the filter body to the oil filter bracket.
4. After warming up the engine, check for engine oil leakage.
5. Check engine oil level and add engine oil. Refer to LU-18, "
ENGINE OIL" .
Draining WaterELS000CJ
1. Prepare a tray at the drain hose open end.
2. Loosen drain cock, and operate priming pump to drain water
from fuel filter.
CAUTION:
●Water in filter is drained with fuel. Prepare larger capacity
pan than fuel filter volume.
●Drained water is mixed with fuel. Prevent fuel from adher-
ing to rubber parts such as engine mount insulator.
3. After draining, close drain cock by hand.
CAUTION:
If drain cock is tightened excessively, it may be damaged
and fuel will leak. Do not use tools to tighten drain cock.
4. Bleed air in fuel piping. Refer to FL-16, "
Air Bleeding" .
5. Start engine and check fuel leakage.

a. Park vehicle on level surface and set parking brake.
b. Start engine and move selector lever through each gear posi-
tion. Leave selector lever in “P” position.
c. Check fluid level with engine idling.
d. Remove dipstick and note reading. If level is at low side of either
range, and fluid to the charging pipe.
e. Re-insert dipstick into charging pipe as far as it will go.
