2. Check engine oil
3. Check battery
4. Check air cleaner element assembly
5. Check spark plug
6. Check drive belt
Figure 1
Notice:
zCheck the belt deflection at the specified point See (Figure 1).
zSet tension to specified value when installing new belt.
zCheck the deflection to ensure it is below the specified value after the belt runs for over 5 minutes.
zReinstall the belt which has been running for over 5 minutes. The deflection of the old belt is regarded as
the standard for inspection.
zCheck V-belt for tension and distortion after the engine cranks for 2
turns.
