GENERAL MAINTENANCE
1. GENERAL NOTES
Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performed.
Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).
Maintenance service after the last period should be performed at the same interval as before unless
otherwise noted.
Failure to do even one item an cause the engine to run poorly and increase exhaust emissions.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the ºFULLº and ºLOWº lines on the see-through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upper and lower level lines on the case.
6. BRAKE AND CLUTCH FLUID LEVELS
Check that the brake and clutch fluid levels are near the upper level line on the see-through reservoirs.
7. ENGINE DRIVE BELT
Check drive belt for fraying, cracks, wear or oil contamination.
8. ENGINE OIL LEVEL
Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL
Check the level on the dipstick.
The level should be in the ºHOTº or ºCOLDº range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all positions from ºPº to ºLº,
and then shift into ºPº position.
(c) Pull out the dipstick and wipe off the fluid with a clean rag. Re-insert the dipstick and check that the
fluid level is in the HOT range.
(d) Do this check with the fluid at normal driving temperature (70 - 80°C, 158 - 176°F).
HINT:
Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speeds, in hot weather, in heavy traffic or pulling a trailer.
11. EXHAUST SYSTEM
If any change in the sound of the exhaust or smell of the exhaust fumes is noticed, have the cause located
and corrected.

13. ACCELERATOR PEDAL
Check the pedal for smooth operation and uneven pedal effort or catching.
14. CLUTCH PEDAL (See page CL-3)
(a) Check the pedal for smooth operation.
(b) Check that the pedal has the proper freeplay.
15. BRAKE PEDAL (See page BR-7 )
(a) Check the pedal for smooth operation.
(b) Check that the pedal has the proper reserve distance and freeplay.
(c) Check the brake booster function.
16. BRAKES
At a safe place, check that the brakes do not pull to one side when applied.
17. PARKING BRAKE (See page BR-9)
(a) Check that the lever has the proper travel.
(b) On a safe incline, check that the vehicle is held securely with only the parking brake applied.
18. AUTOMATIC TRANSMISSION ºPARKº MECHANISM
(a) Check the lock release button of the selector lever for proper and smooth operation.
(b) On a safe incline, check that the vehicle is held securely with the selector lever in ºPº position and all
brakes released.

(b) Remove the 2 through bolts.
Torque: 5.9 N´m (60 kgf´cm, 52 in.´lbf)
(c) Pull out the field frame together with the armature.
HINT:
Align the protrusion of the field frame with the groove of the
magnetic switch.
(d) Remove the O-ring from the field frame.
HINT:
At the time of installation, please refer to the following items.
Use a new O-ring.
3. REMOVE STARTER HOUSING, CLUTCH

6. INSPECT BRUSH HOLDER
Check the brush holder insulator. Using an ohmmeter, check
that there is no continuity between the positive (+) and negative
(-) brush holders.
If there is continuity, repair or replace the brush holder.
7. INSPECT CLUTCH AND GEAR
(a) Check the gear teeth on the pinion gear, idle gear and the
clutch assembly for wear or damage.
If damaged, replace the gear or clutch assembly.
If damaged, also check the drive plate ring gear for wear or
damage.
(b) Check the clutch pinion gear.
Rotate the pinion gear counterclockwise, and check that
it turns freely. Try to rotate the pinion gear clockwise and
check that it locks.
If necessary, replace the clutch assembly.
8. INSPECT MAGNETIC SWITCH
(a) Check the pull -in coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween terminals 50 and C.
If there is no continuity, check and replace the magnetic switch.
(b) Check the hold-in coil for open circuit.
Using an ohmmeter, check that there is continuity be-
tween terminal 50 and the switch body.
If there is no continuity, replace the magnetic switch.
9. INSPECT BEARING
Turn the bearing by hand and while apply inward force.
If resistance is felt or bearing sticks, replace the bearing.
